Evo Motor Assembly Part 3 Installing Cam Bearing and Main Seal

[@truethought369]

Hi Mike, Nice cam tool, like you say, having the right tools really helps! Yes, I prefer Needle rollers rather than bushes to. Showing things a few times over is the best way for people to learn. The old saying comes to mind: "Repetition is the mother of Retention".

[@pacificmike9501]

Thank You. I started my first job in a motorcycle shop by picking up a broom and sweeping the parking lot. No pay. Nobody asked me. A mechanic asked me to come in and give him a hand, for a minute. That minute stretched into a lifetime. It's been a blessing and a curse. I wouldn't trade it for anything.

Really loving the EVO rebuild I have a 95' EVO 80 and I am having what appears to be lifter/vaulve noise. when you get to that point could you please show a detailed view of adjusting the vaulve/lifters?? I like to do my own work and I am a novice when it comes to the mechanics of this bike. again thank you for you teaching style it really resonates with me.. great job!!!

[@pacificmike9501]

Thank you, and, yes I will. Don't know how many miles on your Evo, but, if it's making lifter noises, better inspect. When they "self-destruct," they can cause some damage.

Thank you for all your videos, they're very helpfull. I have a leak from the main seal to my dry primary. Can I replace the main seal and the spacer easly or I need some special tool to extract the spacer?

[@pacificmike9501]

Yes you can! Just be careful you don't damage the area the new seal is going to contact.

[@a_aronhdtech]

great vid. If I can be so bold as to put my 2 cents. I'm not sure what kind of bearing you installed. In my ,15 year, career of working on Harleys I would always recommend a continues bearings vs the cage bearing that comes from the factory. Makes for a much stronger bearing. Ok, I'm done. Thanks and I enjoy watching your vids.

[@pacificmike9501]

You bet.

[@61espo]

Great info!

[@pacificmike9501]

Thank you.

[@michaelschramm6571]

Great video Mike. I have a problem, 1990 Evo on my Heritage keeps filling the primary. I've replaced the seal and spacer twice and although slowed, I'm still getting oil leaking into the primary. What am I not doing right? I have the seal going in just like you showed in the video. I need your wealth of learned knowledge. Thanks, Mike

[@pacificmike9501]

I'm just an old mechanic. I certainly can't see it from here. But, I do recall in about 89 or 90, there were some crankcases that failed. They cracked where the boss for the drive side bearing race was "cast in." I hope that's not it, but it is fairly common.

[@Kevin_747]

Any issues with using an old camshaft to drive a new bearing in? Thanks for the video.

[@pacificmike9501]

I prefer the tool that takes it in slow and easy. Do what you prefer. I show my favorite methods.

[@dougkommersmith6129]

Wanting to put a ev27 cam in my 1986 soft tale. I've heard people say to use your stock cam gear. Is it nessary to do that ? Love your videos. Thanks Mike.

[@pacificmike9501]

You're probably okay with the Andrews cam gear that came with the cam. If it isn't noisy, cool.

[@batsy74]

Is that main seal rule the same on a shovel head? If I convert to an isolated primary (i.e. primary not running off of the oil pump) or to a dry belt drive do I need to pull the seal and spacer and flip them around (after I replace them of course)?

[@pacificmike9501]

When you modify things, it's on you. But, as I mentioned in the video: Are you trying to keep oil in, or out? That destermines the direction of the seal.

[@brianvandemortel6710]

I picked up a 95 Sportster 1200 for my son on a trade it’s a little rough but I have gotten it to run pretty good but have noticed a leaky base gasket do you have any videos on something like that it would be a great help thanks Mike

[@pacificmike9501]

It's basically the same as on a Big Twin (91 and later) Evo. Details are in the service manual.

[@irakoflowitch9368]

Mike, Love the videos. You are an excellent teacher. I have a '93 Evo that I purchased brand new. I changed the oil and filter every spring and never abused it. At about 35,000 miles the cam bearing failed, and I needed to rebuild the engine. I have been informed that this is a fairly regular occurrence on early to mid 90's Evo's. What do you know about the Motor Company using an inferior cam bearing in these engines?

[@pacificmike9501]

It is recommended that the original cam bearing be replaced with a Torrington bearing with a full compliment of rollers in it. This is recommended by camshaft manufacturers and as mechanics, anytime anyone is into the camchest on an Evo, with an original bearing, we generally replace it. Customary to replace it when replacing the cam. Personally, they rarely fail. But, I've certainly replaced a bunch of them that were doing just fine.

[@jberschi]

@@pacificmike9501 Is there a tool to pull that bearing out without splitting the cases and pressing it out from inside?

[@Cpcsof1]

I notice the new torrington bearings have koyo on them. Are the new ones as good as the old ones that said torrington on them? Also, I looked up the Jims tool cam bearing installer that you are using. The specs say it only installs the bearing. They list another Jims tool for removing the bearing. Do you use another tool for the removal?

[@pacificmike9501]

Yes.

[@Cpcsof1]

@@pacificmike9501 Thanks! These videos are very helpful.

[@donniemiller7347]

Really good videos, thank you. Have a question, I'm rebuilding a 1989 Electra glide classic with a 1340 evo motor. I have it all broke down, trying to replace the bearings on the crankshaft, have any suggestions of what kind and where to buy them?

[@pacificmike9501]

Buying them is no big deal. Anyone who carries parts for Harley Davidson motorcycles can get you anything you need for that motor. Installing new bearings in the lower end without experience or special equipment could be disasterous. I don't mean to talk down to you. You could very well have twice my intelligence and capabilities. But, this requires the attention of a trained professional.

[@timwillis73]

When you break a engine down this far do you always replace all of the bearings for crank and cam. Tim

[@pacificmike9501]

If you're going that far, replace everything you can. Don't want to go back there for quite a while.

[@dictumfactum9468]

Hi Mike, Im getting ready to do a cam and bearing upgrade on my EVO. Im guessing you removed the original cam bearing when the cases were split. Do you have any video of a cam bearing removal with the Jim's puller? thanks

[@pacificmike9501]

I looked through the videos we've done and found I've never shown the actual removal of the cam bearing. In the next few weeks, I will have an Evo apart for one one of my old friends. We're putting a fresh High Performance topend on it and I'll be changing the cam. Therefore, I will remove and install a new cam bearing. The process is the same for 1958-1999 Pan, Shovel or Evo. Sorry, waiting for the topend to be done. Again, super high performance. Great things take a little time. It will be here in few weeks and I'll demonstrate the cam bearing removal and installation.

Hello mike I have problem my 1995 Harley Davidson blew a rear head gasket on the right hand side witch burned the area of the cylinder.the Bike is a Electra glide classic So my question is if I had it professional welder take care of that or just replace the cylinder all together thank you for your information. Have you ever done this before as welding the cylinder. I will be running my compression 10 to 1 ratio using S&S Super Stock Heads with the corresponding pistons. Thank you .

[@ajkylen]

This is a evolution motor 1995

[@pacificmike9501]

I'd buy new cylinders. The question is, "Why did the gasket blow? Did you pull cylinder studs?" Better inspect things very carefully.

[@RM-oc8tc]

Great videos! One question my local guy, been working on harleys for a long long time installed my cam bearing backwards, rounded side out. Should I have It pulled and a new one pushed in properly or if it spins freely leave it? Thanks.

[@pacificmike9501]

Can't see it from here. But , probably okay if it wasn't distorted, which would make it not turn freely.

[@RM-oc8tc]

Hello Mike I have a 98 road king and I’m doing a cam upgrade and when I put the piston to top dead center the timing marks don’t line up I need to move the piston down to make the pinion gear mark at the top. Any help would be appreciated. Thanks

[@pacificmike9501]

The timing marks on the gears only relate to the timing marks on the gears. Don't worry about anything else. When installing the gears in the gearcase nothing else will seem to be in proper sequence. You're fine.

[@lawrence9504]

You’re good

[@pacificmike9501]

Thank You.

[@joerectifier]

Especially because you have the proper cam bearing install tool, there is simply no need to install the bearing with the case split. For folks that might be “improvising” with methods or experimenting with improvised tool devices (IDDs), they might find some leverage in pounding the bearing in if the cases are split and the cam chest half’s back side can sit flat on the table for said pounding 😅😂

[@pacificmike9501]

This is no place to mess up. Buy the tool.

[@pacificmike9501]

Depends on how bad it is, and where the pieces went. Worst case, complete teardown.

If the bearing fits good and tight, maybe there's enough lip for the bearing to "register."

[@bah667]

Do cams come with a bearing? or is it one size fits al

[@pacificmike9501]

Not usually. Open your parts book and look up the part number. Or, look in a catalogue that carries such things and order the bearing for your specific year and model of motorcycle.

[@Bidenrocks13]

Always buy the harley manual for your specific year and model. Best money you will ever spend. I also buy the year model specific parts book. There are great breakdowns i use to locate items.

Mike, you forgot to check to see if the needle bearing rollers are straight and that the rollers turn free after installation. It is important to check things like that.
