You are the only mechanic on UTube that shows and explains in detail what, how and why. No beer drinking, backs of people doing God knows what and jerking around like a pack of gorillas. You are the professional. Thanks Mike.

Always great to watch your videos Mike. Calmly explained without cursing or condescension or slick editing to make it appear as though you never struggle or forget something. Always get what I need; every time. A true gentleman. Thank you for all you do.

Thanks a lot man! I've built Harley, and car engines for 30-plus years, but I have learned a lot from watching you and your techniques. Really appreciate it!

[@pacificmike9501]

Thank you.

[@rcanoli99]

this is such a great lesson and timely for me too since I have to replace the cam on this '81 WG I just got. I really love how you tell us the little details of what you're doing, like when you're pulling the cover back off and you say, "I'm holding the cam gear with my thumb..." - seems like a little thing, maybe obvious but for newbies to a cam chest like me those details are music to my ears. From watching your videos I'm building up the confidence to do this job. Thanks so much Mike you're the best!

[@pacificmike9501]

Thank You. I do try to show the things that are done "automatically" by people who do them often. Word to the wise for you: Be very careful selecting a cam for your 81. There are certain differences in the cylinder heads that have to be allowed for. Check with the manufacturer of the cam. Notice in the literature, that it addresses 81's.

[@rcanoli99]

@@pacificmike9501 Thank you Mike - yes I've noticed when looking for a bolt-in replacement that nearly every manufacturer states, "bolt-in except 80/81" but none explain why. I know the guides changed from steel to cast iron in 1980 and also the length changed to 2" in 1981. Beyond that I assume the manufacturer will know so thanks for the advice I will speak to the manufacturer before I buy a replacement.

[@garryfuller3400]

This video along w/ comments helped a ton. Hard to believe the timing marks on left don’t have nothing to w/ the ones on the right. Now we know. Awesome as per usual. Thank you sir.

[@keesketsers5866]

Great video! This shows very well that a gasket has a big influence on clearance in the engine in some cases! Never realized that fully I guess, also using non-factory gaskets (silicone bead gaskets etc.) might change things considerably. I really learned something today, thanks!

[@billvandyne4685]

Mike- I figured it out. A shim was stuck onto the thrust washer. I got it apart, cleaned everything up, and installed a smaller shim- problem solved. The end play currently reads 9 thousands. I may install a slightly thinner shim for a bit more end play. Thanks so much for the advice- your instructional videos are the very best!

There is a comment a couple above yours. Make sure you're not overfilling the tank. Always leave room for the breather to put some air in there. Watch it run with the oil cap off to make sure the oil is returning to the tank.

Mike, This video series has become invaluable to me and extremely relevant to my situation. My Dad passed and I brought home his 14k mile Dyna Glide Shovelhead that's been sitting for 30 years. I feel like following your videos are the guidance I need since I'm still learning about what makes a Shovelhead work. I'm wondering...what your technique is for getting to crankcase so clean? What do you think about trying to get it to fire up before taking anything apart?

[@pacificmike9501]

I'd check things out very carefully first. I'd crank the motor over by hand with the spark plugs out. How about the oil. I'd probably freshen an awful lot of stuff first. There are no Shovelhead Dyna Glides.

[@Brian-vr1rh]

@@pacificmike9501 My Dad's old Super Glide (Dyna oops) is still "new" to me as you noticed. How did you get that motor so clean? Brakecleaner? degreaser? brass brushes using either?

Great videos....you explain each process perfectly.On this,I would have liked to see you turn the motor over by hand at the end,to ensure all well and good with cam,breather and cover installed.My shovel tightened up after 2/3rd revolution.On rechecking,finding nothing,reassemble..... and same problem? With a new cam and bearing,breather,timing cover bush etc. it was found that the genuine cone cover was at fault. It had been bored incorrectly (about 0.025" out) for the bush,so cam ran out of alignment.....which would explain the excessive wear in there and the thrust washer blue with heat and welded to the cam! Just one of those freaky instances. It taught me to rotate everything by hand at each stage of assembly,to ensure all is good. That cover now hangs on a nail from the rafters! A second hand cover was found,re bushed,honed to suit cam, and all was perfect. Thanks again for these very watchable and educational videos. God bless.

[@pacificmike9501]

I agree. When I look things over, it's easy to tell they were in good working order. But rotation of everything to check is good and necessary practice. And, thank you for the compliment.

Hey Mike, thank you for putting out many video's on all different model bikes! I've learned a lot, I have a question many you can help me with this one. it's a 73 FLH, after I set my cam, pinion and breath gear and all my timing marks all line up right, does the fly wheel need to be on the lower dot which is the TDC or on the advance center line, or neither, and just adjust my points accordingly ? boy would love to hear from you! there really aren't a lot of old timers that know about older bikes, between watching TATRO and Mike's garage, your more thorough and easy to follow. thanks again for making these awesome videos!

[@pacificmike9501]

Thank you for the kind words. The timing marks on the flywheel won't line up with the timing marks in your camchest. Once those are set, and the cam cover is back on, bring up the advance timing mark (the straight vertical line) on the flywheel. This must be done with the front piston on its compression stroke. Both the intake and the exhaust valves on the front cylinder, should be closed. Read it in your service manual. With what they say and what I say, it should be fine.

[@Billybob58-xf4hq]

Mike, love your channel. I have a 2 part question. I have a 1966 FLH that the previous owner installed an ss oil pump-love it. Noticed that he has plugged off the primary chain oiler on the pump and removed the hose feeding it to the chain. He left the fitting in the inner primary but did not plug it, it is open to the atmosphere. When I pulled the outer primary off there was a small amount of oil in it, maybe a couple ounces? #1-Should I plug the fitting in the inner primary and add oil to a sealed primary, if so how much oil should I put in. #2-Should I install the fitting in the oil pump, run a new oil line and run it like stock? I'm not sure how this would not eventually overfill my primary, I don"t understand the oil return back to the crankcase set up either. Please let me know your opinion on this, I cant seem to get any definitive answers from any mechanic I know. Thanks, Bill

[@pacificmike9501]

I explain this on one of our videos (oil lines on a Shovelhead). I recommend setting it up like the factory did. A lot of people think they can eliminate the original oiling system to the primary. By putting a couple of inches deep oil in the primary, iit leaks out and never does oil the primary chain like it needs. If you look in your service manual ( probably the 59-69 book) along with our video, it should become quite clear. If not, write in again and we'll go over it again. The stock system works fine. That's the way it was designed, it doesn't leak everywhere and it runs a dry clutch.

Hey Mike, I absolutely love your videos. Thank you. I have a question. I purchased an S&S oil pump for my 77 FLH. It comes with a new breather gear. I went to measure end play, like you showed with a straight edge. I am coming up with .009 without a shim. You suggested .011 To compensate for gasket crush. Do I run without a shim?

[@pacificmike9501]

I believe I suggested .011 on the cam. This is something you should be going over in your service manual. You're missing too many important points. And, you'll find more info in the package of S&S parts. And, if you lost the instructions, go to sscycle.com

[@killat0r]

This is amazing! Just to clarify - do you not have to put grease on the Cam box cover gasket like you did the oil pump gaskets?

[@pacificmike9501]

Depends on the gasket. The manufacturer's recommendations should be followed. The thick ones usually are installed dry. They compress and make a seal without any help. The thin ones, well, maybe a little sealant. Oil pumps can be difficult. I like white lithium on them. You need to find the products you like. We just show how I do it.

Thank You. That wheel took a great deal of adaptation. I used one of Paughco's super long axles. I used sealed bearings, like the wheel came with, only 3/4" rather than 1" i.d. I had to use a very late rotor for the 2.2? center hole. I made my own caliper mount and spacers. It was quite a project.

Hi Mike , thanks for all your videos on you tube they are very helpful. I have a question about end play .As you discuss in the video Cam end play should be 5 thou . I have done that but find myself questioning myself as on the Net and forums talk about 10- 15 thou end play with Andrews Cams as they expand on Heat. Confused to say the least .just don't want things to bind once Running. .

[@pacificmike9501]

Good question. I don't remember what your bike is. The generator type motors call for the 1-5 thou type of end play. Sorry. Too tight for me. The later manuals (alternator type motors) call for much more. I favor loose over tight any day in a motor. The late manuals (Evos) say enormous camshaft endplay. I believe most of them didn't even have a cam shim in them. .011, .012, .014, .015. All good to me. If you have a Knuckle or Pan, or even a generator Shovel, you can run it a little tighter. I hope this puts you at ease a bit.

It's not set up that way. Just do it, like you said, by the mark on your pinion gear. Don't overthink this one. The pinion gear only goes on in one position. It's a little maddening when you think about it. Line up the mark on the pinion gear with one of the marks on the cam gear, with the other mark on the cam gear lining up with the breather. Just be sure of your end plays.

Mike, can your flywheel be 1 rotation out when you re-align your cam and breather? My timing marks aren't jiving with top dead center anymore. Thanks!

[@shovelhead1871]

i have same question..... i just installed a new cam, andrews "b" grind.... there is no suction through carburetor

[@pacificmike9501]

Nope. You don't time your cam and breather gear to the flywheel marks. You time to the the pinion gear which only assembles one way on to the pinion shaft. Mark on pinion gear points straight up. It lines up with one mark on the cam gear. The other mark on the cam gear lines up with the mark on the breather gear. Now, before starting the engine, rotate it to time the ignition to the timing mark on the flywheel when the front cylinder is on its compression stroke. Both valves are closed and the piston is coming up. Its hard to accept the fact that the timing marks on the right side don't reference to the timing marks on the left side.

[@flagstamp]

@@pacificmike9501 Thanks Mike! That makes sense. I'm getting tripped up on my rear cylinder pushrod adjustment, because I'm not getting the small dot in the viewing window. I thought it was due to my cam being out of sync. I'll keep at it 👍

[@pacificmike9501]

I think you're looking for a problem you don't have. Set up your camchest. All this is on the right side. Now , adjust your valves and set your timing (using the flywheel "advance" mark, which is a straight line). This is done off of your front cylinder. I'm assuming you're not dealing with a "dual point" setup. Just a question for you: You've picked an Andrews "B" grind cam. Are your valves set up for that much valve lift?

[@billvandyne4685]

Mike--i have a question. I am in the process of installing an Andrews J grind cam in my '77 FXE. In measuring en-play, it seems to be good without a spacer ( only the trust washer is installed). Is it OK to run the cam without a spacer? Thanks.

[@pacificmike9501]

Yes, but, did you remember to measure with the gasket installed and allow for it's thickness?

[@billvandyne4685]

@@pacificmike9501 Thanks. Yes, I've measured it with a new gasket installed. I can't detect any movement in the cam w/o a shim installed but the thrust washer moves freely--so, it obviously isn't jammed against the washer.

[@pacificmike9501]

You have me a little bit concerned. '77 early bikes had different gears in the camchest than late '77 and up. The late cam gear has a groove on its face and the early does not. Make sure you have that right. Next, is this the original cam cover that came with the engine? Is the breather gear shimmed correctly. Next comes the face on the bushing pressed into the cam cover. Is the cam bearing seated into the crankcase all the way? Finally, there are different cam cover gaskets made by different manufacturers. Some are thicker than others. Remember, that camshaft is better a little loose, than too tight. I'm truly sorry I can't see it from here.

[@pacificmike9501]

Also, the cam grinder recommends a specified clearance. Read and adhere to the directions.

Put the oil pump gear spacer and pinion gear in, went through all the steps with the breather gear and clearance for camshaft. Gear on the camshaft is out further than the pinion gear by almost 1/8”. ????

[@pacificmike9501]

I can't see it from here. Is the cam bearing seated in the case? Is the cam gear pressed all the way onto the cam? How thick is the cam shim? Is the "cam plate," the "bow tie" looking piece? What year is your motor? Is the camshaft correct for the motor. Big groove on the face of the gear for late 77 and later motor. No groove for 70-early 77 motor.

[@tomteevo]

@@pacificmike9501 After looking at it and guessing at the measurement i got a straight edge and gauges and checked it, the cam gear is .056 out further than the pinion gear and breather gear. I am using a new set of S&S cases after i found that the right side case i was going to use was cracked. The cam bearing is seated correct, got the cam gear spaced correct , and after three tries i got the clearance for the cam shaft. The cam plate is indexed as you showed in the video, and the cam shim is .065. Cam is Andrews "C" for a 1974 shovelhead, also have a Andrews "7 grind" cam and they both fit alike. Everything was ordered for a 1974 shovelhead, hot kit, and cases.

I meant breather gear where i said cam gear spaced correct

[@Cickstart]

question ...... on a panhead ... all the timing marks gears in place, if i drop the Distributor in place with the timing marks to the points TDC ... does that guarantee that the front cylinder, with the flywheel mark is the correct TDC for the timing order ? and not 180 de grease off?

[@pacificmike9501]

Nope. Once all the timing gears are in order, forget about them. Now, we'll time the distributor. Rotate the engine to bring up the timing mark and watch the valve lifters go up and down for the front cylinder. When the flywheel timing mark comes up and the points cam is getting close, and both front valves are closed, you are there. You are timing on the slash mark which is the Timing advance mark. Look in your service manual. This is with the timing fully advanced.

Hey mike, got your email on the rear centerline rim. i wrote down all the info you gave me and will be looking into it. my axel is at the salt lake chrome with some other parts, as we are in northern wyoming and he has done good stuff for me in the past. i think the previous owner who is dead now so i cant converse with him as yet, put on a wider rim. i measured the out side to outside and its like 4 3/8 wide with calipers across the outside. i thought 73 flh's had a 3 inch rim. so when the axel comes back i'll measure the length and see if its a longer than stock. we purchased the bike in 2008 and the previous owner who bought it new did some stuff to it like S&S rods and flywheel for 4 1/2 stroke and S&S pistons. Offhand, do you know what stock harley rim width for 1973 flh was. I have to get a new tire anyways, thats why i was contemplating that rim i saw on yours. I'll remeasure the rim inside when the tire is off. I guess that rim like yours would work on the 73 flh if i change the bearings to accept the 3/4 axel and have to wait and see what my axel length is when it comes back. and i would have to fabricate brake brackets. that is a 16 inch rim? that frame in video you have the shovel head engine and that harley centerline rim on, is that a 70's shovelhead FLh frame? thanks Mike. Dave in northern wyoming

[@pacificmike9501]

Yes, stock rim width is 3". I did so much stuff there, I think yours is a little simpler. Stock axle is long enough and should work fine after you've installed bearings with 3/4" i.d. I used an earlier round swingarm. It was something I always wanted on the bike. The brake was the big part of the job. The caliper and rotor are off of a (I believe) 2008 Dresser. The center hole has to be 2.2?. I made the caliper bracket from scratch.

[@georgejanz1313]

I used the headless bolt alignment method, time and frustration saver! Question, 3 types of gaskets are available for the cam cover, paper (.031 thickness specified), paper with bead (thickness not specified), and rubber covered metal with bead. (thickness not specified) The choice may impact the cam gear end play? The old one was paper, no bead. I'll most likely stick with that unless there's a strong recco to change to one of the other options. Thanks for the vids and in advance for reading this.

[@pacificmike9501]

The point of using any specific gasket is to end up with the endplays (cam and breather gear) that you want. Set the breather gear acoording to the service manual and the cam according to the cam grinder. If you use the same kind of gasket each time, you'll more easily be in the ballpark on your requirements.

[@georgejanz1313]

thanks. If I am understanding, the manual says for Cam gear end play .001 - .005. Measuring mine, I can't get .0015 in there.Current spacer size is .075. My choice is a space of .070 so I will end up with about .005. Correct path? @@pacificmike9501

I measured the breather gear as you/then manual describes and end up with .002. Thanks

[@pacificmike9501]

Did you allow for crush of the gasket? Sounds a little tight to me.

[@georgejanz1313]

For both measurements I used the gasket that was on the bike when I began the operation. I'm waiting for a new one. I measured the thickness of the one I'm using in it and it is .030. when I measured the cam gear end play I also put the cover back on and torqued it down to the 80-in pounds. My take is they're both a bit tight. So I bought the appropriate sized spacers. I have a second super glide exactly like this one. I'm going to put it on the lift and measure the cam gear and play for a point of reference.

[@mattroscoe7810]

Love the videos but I do have a question when u have the cam installed are you on TDC? I'm working on a 78 shovel head and it's a rebuilt engine but had to remove cam gear cover due to engine setting but with it off TDC marking on flywheel never has the cam and crank and the breather gear line up

[@pacificmike9501]

Don't try to find a correlation there. They aren't interested each other. Don't let the right side even converse with the left side. I know it sounds silly, but it is true. TDC is with the flywheel mark (Front cylinder) with both intake and exhaust valve lifters on the front cylinder in the bottom position.

A little too tight for me. A seized cam is really ugly. Be sure and pay attention to what service manual you're using and the cam grinder's recommendations.

[@72nortoncommando]

Better off without the flashlight with timing marks.. camera picked it up just fine..another great class. While on cam covers, the difference between early 1972 and 73, and 73 and up which has several changes is not really covered by HD. Maybe you could clear it up a little better, putting wrong cover on a new build would have disaster written all over it

[@pacificmike9501]

It's usually, "Does this motor have side oiling or center oiling into the pinion shaft."

[@pacificmike9501]

The other question is, "Did this cam cover come with this motor, or has it been changed." It can get real exciting from there.

I have an 83 flht that I am rebuilding. I dont like how hard it has to work to keep up with traffic on FL highways so I am looking at replacing the the cam, rear sprocket and trans sprocket. Do you have any recommendations on what I should get to give me the power and performance needed to keep up with the flow and not kill the bike? Any advice would be greatly appreciated.

[@pacificmike9501]

A couple of teeth on the trans sprocket usually will do it. The five speed gives you a low enough first gear. A nice hydraulic cam (first step, nothing too wild unless you build everything else to match), but I don't push brands. You'll have to decide what compression you're running to pick a cam. Use a good set of aftermarket hydraulic lifters. If possible, a more free flowing exhaust system, better carburetor and ignition system. This should all be planned carefully.

[@pacificmike9501]

Problem is, I can't see it from here. But, it sounds like you have an earlier pinion gear. Looking straight at it, the mark at two o'clock would align with the circuit breaker gear on a '69 and earlier motor. The mark straight up will line up on your cam gear. Check this out very carefully before starting your motor. I think it's a case of mix and match.

No. Everything in the camchest times off of the pinion gear. It all matters, but you arrive there by timing the camchest, then the flywheel mark and then the ignition. The pinion gear only installs in one position.

Some of that stuff only goes together one way. Flywheels onto the crankpin. Pinion shaft onto right flywheel. Pinion gear onto pinion shaft. Now it goes into the cases. When the pistons come up, the timing mark on the left flywheel comes up in the window. Other than adjusting the ignition, it's all timed. Oh, now you want the gears in the camchest. Timing marks on pinion gear (which only goes on one way). Now slide the gears in place as per the picture in your service manual.

Hi Mike On a 69 generator shovel is it possible to have the breather gear 180 out . All timing marks where lined up.

I was able to kick it over and slide breather back into alignment. Just didn't know if it can be 180 out.?? Thanks

[@pacificmike9501]

First off, don't do that. You can rotate things slowly by hand before pushrods and sparkplugs are installed. The cam should be supported by the cam cover, If your gears are all lined up properly, they are because the marks are all in place. They only go together one way. You're probably just fine.

It's no big deal to change the cam bearing. The tools are specific to the job. I can't tell you how many guys would bring their bike in the back of a truck, with the cam cover off.

The cam bearing should be replaced if there is any question. Replacing one when the cam is replaced is standard procedure. It's simple to do with the proper remover and installer.
