Harley Davidson Twin Cam - How To Disassemble Top End for Rebuild

In this video, I will show you how to disassemble the top of this Harley Davidson Twin Cam.

[@brianluck84]

What I'm mostly impressed about is that you didn't have to spend 3 hrs looking for the 10mm and inevitably going and buying a new one. Kudos

[@DeathProofProductions]

thanks.

[@jameshopkins8415]

How much tipaclly does a job like this cost

[@linussphinx1353]

[@goatandyourmom9690]

I'll do one better. I went and bought one before I even got started on mine lol.

Thanks will do.

[@user-rb8xo3cz8t]

I really need to learn this ASAP I am a mechanic I figured it out only thing confusing me is the valve tubes cut them with bolt cutters and replacing them with s&s adjustable is that why everyone cuts them of ?

[@DeathProofProductions]

We cut the push rods to make it easy to open the cam chest for inspection or cam swaps. Saves having to remove the top end.

LoL I got the balls.. About to embark with a big bore kit.. :) This video rocks.

[@dereknoel265]

So how did it go?

[@petelanzone484]

@@dereknoel265 I have it back together as far as I can go. Waiting on the heads from machine shop from port and polish. I just received notification they should arrive at my door step Monday Feb12th. I sent them out right before Christmas of 2023. Once I get them back I can commence. I already have the dyno/tune lined up. He is waiting on me ;)

[@petelanzone484]

@@dereknoel265 Bike is done. Dyno and tuned from the big bore upgrade. Picked up about 20HP and about the same in torque. Like the video, if this is something you wish to tackle your self . I say go for it. If you can wrench on a lawn more. You can do this. It was satisfying and learned things along the way.

Totally dig the channel man. Sub for sure. Got a used 04 road king at a great price, 37 thou miles, it's had the 95" top end done to it with s.e. cam plate with 525 cams. It's a strong runner, I've been using Lucas syn oil. My mechanic told me those flat top s.e. pistons are junk cause their not forged. What's your opinion on that setup?....any advice you have will be well recieved.

[@DeathProofProductions]

S.e. piston are hypertectec just like the rest. If ur not drag racing for a living your fine. Remember guys like that make a living selling parts. Always remember the that myth busters figured out frog pee doesn't cause warts.

[@DeathProofProductions]

go to my home page i have a video called cheapest way to prevent cam chain tensioner failure. I go into that. thanks

[@goatandyourmom9690]

Do you gotta tdc or anything? Or is it just cool to pop the heads and jugs?

[@DeathProofProductions]

You can just pull them.

[@petelanzone484]

does "Fast Freddy" still do porting and polishing of heads? I recall one of your other videos you put up his info. But found scare info on the web.

[@DeathProofProductions]

His son Ben does most of the work now. Alot of the racing guys in this part of arkansas have him do there work. I'm not sure if Ben has anything on the web our not but his number was on the card, give him a call and he can tell you more.

[@beausbargarage6213]

please can you just confirm to me that when removing the rocker arm assembly they just have to have play on both? as in push rods are no pressure? Does it matter what stroke the motor is on? Im going to just make sure they wiggle please if you can let me know

[@DeathProofProductions]

Really it doesn't matter if they have pressure on them. Just when you reinstall them take your time tightening them down. If your using adjustable push rods than you do bump it over until the lifter is level with the anti rotation pin. I almost never bring it to t.d.c to do anything on the top end.

[@whip-its_dad4239]

Thanks for the great informational videos . But you got to stop drinking that stump water beer and get some real good tasting beer. I wish we were neighbors . And Im just kidding about the beer .

Please god. What tool did he use to get those 1/4 hex bits off that crossover pipe between the jugs

[@DeathProofProductions]

You talking about the intake

[@stuartburchell8478]

what was the cause of the carbon build up? mine has 1/8" build up on cylinder ad head after 30000 miles

[@DeathProofProductions]

Breather gasket was letting rocker box oil leak into it and into the intake for about 25000 miles. I noticed when we rode to Sturgis that he had alot of oil coming from his air cleaner so I new the breather was leaking. That's why I had him let me tear into the top end and put all new gaskets in it and inspect everything.

[@jactilm8687]

And every body was saying the twin cams are junk.

[@davidswick8353]

Right now, my intake manifold bolts are not wanting to loosen!

[@DeathProofProductions]

What kind of Allen are you using.

[@davidswick8353]

Solved the problem with some heat. Prior owner used Locktite. Thanks for responding.@@DeathProofProductions

[@murphy6767]

You should do a compression and a leak down test on your Dyna to help us new bees... lol Thanks..

[@DeathProofProductions]

thats a good idea. I have several we're filming now but I might be able to squeeze it in.

[@murphy6767]

Thanks...

[@murphy6767]

question. When i done my compression test and i unhooked my auto compression releases the compression was 215 on both cylinders. when i left them hooked up front 100 and back 120. now i dont understand the difference between that? Pleases help.. Thanks

[@DeathProofProductions]

Let me make a video. It will explain it better. Alot of things can affect the readings. And since I'm not there to see the readings, just watch me on the video.

[@murphy6767]

Ok thanks I really appreciate it.

[@kennethmabus381]

I got a twin 95' kit just blew a head gasket on front jug. Had the compression release stuck open as the button came off and then didn't pop up. You think that would have caused it?

[@DeathProofProductions]

No that shouldn't have caused it more than likely it was a head bolt issue.

[@kennethmabus381]

@@DeathProofProductions thank you sir!

[@kennethmabus381]

Well I disassembled everything. That head gasket looks like new and came right out. The head is flat on the mating surface. Hard to believe that is was leaking. Head bolts were tight! But I don't know if they were torqued correctly as I don't see any marks.

[@DeathProofProductions]

Sorry for delay been covered up have you got her put back together.

@@DeathProofProductions yes sir!. Works good now. I'm watching your other videos on things I can tackle. Thank you for sharing!!

Are you going back with new rings and pins

[@DeathProofProductions]

No I checked the service wear limits and it's still got a long way to go.

[@calgreco8607]

Would you throw on new rings?

[@DeathProofProductions]

I checked the ring gap and thrust faces and they were well within the service wear limits. I usually don't replace parts if they have alot of life still in them.

[@Micahmcsartisticleather]

How do I get the last bolt out of the rear head, no clearance

[@DeathProofProductions]

I should have shown how I do that but I didn't think about it. Pry down with a piece of wood and pull it out. Remember it's rubber mounted so it has some play.

[@stevesayers1941]

whats a tawlit? lol :)

[@kennethmabus381]

So i have this nasty racket going on in my 95" big bore on a 2000 electra. I think its a valve . Ive watched your lifters install several times. Ive tried 3 different lifters. The hy-lift slow leak johnson, set of S&S and a cheaper set off eBay. Top dead center, 3 1/2 turns after no lash. No change. I guess I would ask what do i look for in valve body. Broken spring? Suppose ill have to remove the valves to know if ones bent? I pulled the heads and nothing stands out. But certainly sounds like a valve hammering away riding it.

[@DeathProofProductions]

what lift cam are you running.

[@kennethmabus381]

I suppose that's what you were asking is what cams are in it.

[@DeathProofProductions]

Sorry for delayed response been covered up. Did it make that sound after you installed the cam.

[@kennethmabus381]

@@DeathProofProductions no it started over time --after changing head gasket. Which was good it turned out the compression release was bad. But I think I messed it up when I put it back together. Cause I pulled the rockers, and push rods out the top. When I put it back together I put the push rods in, then the rockers and torqued them down. Which I assumed nothing changed as the motor didn't move. But they're adjustable pushrods.
