My Gear Driven Cams Install
After reading and studying this forum and other forum posts (with my thanks to the posters) about installing gear driven cams I decided to do my 2001 FLHTCUI with 30K miles. I completed the job without using any special tools. I did buy harbor freight (HF)3-JAW PILOT BEARING PULLER to pull the inner cam bearings; I slightly modified it to fit behind the inner cam bearings (cut about 3/16-1/4 inch off puller tips). Cut the pushrods out with bolt cutters. I used channel locks/pliers and a drill bit to to pin back the tensioners; the tensioners were worn about a 1/8th inch deep on each one; I think they would have lasted another 20-30k miles. Put transmission in 5th gear and applied the rear brake to remove bolts from crank and cam shaft sprockets. I used a heat gun to heat cam support plate and the bearings/cams came right out; I did have to apply a little pressure to the roller bearing to get it out. I used the harbor freight (HF)3-JAW PILOT BEARING PULLER to pull the inner cam bearings. The heat gun and dry ice was used to install bearings/cams; I used one of the old chain drive cams and a rubber mallet to install/tap-in the inner cam bearings. My crank journal run-out was about 0.0025 TIR. I did not check the inner bearing backlash but the cams rotated freely. I used an undersize pinion gear and checked outer gear backlash and it was about 0.0005-0.001. Installed SE adjustable pushrod kit per the instructions; it took about 25 minutes after adjusting a lifter for it to bleed down. The bike started right up; I let it run about 5-10 minutes; no noticeable gear noise or leaks. When the snow and ice melts here in Oklahoma I will go for a test ride. Oh, I installed S&S 510G cams. I think I have put my cam chain tensioner worry to bed. Will be ready to hit the open road when warmer weather comes.

Congrats! I'm starting my first rebuild with upgraded parts. I bought some special tools just to make life easier but you handled it well. Let us know how it rides.

Cool, good job.
I have a box full of parts waiting to do the same. I'm going to swap out my S&S 510G's for a set of HQ-0039G's. I hope mine goes as smooth as yours did. I've been alittle busy snowplowing up here in IOWA this past week. I might get to the cams next week, will see.

RE: My Gear Driven Cams Install
Condrats!!! I am ordering acomplete cams kit tomorrow. Already heve the pushrods. I also bought the lifters to be installed. Was advised to do so.7 to 10 days to arrive. Then will need to wait about a week to have the job done. Idon't think I can do it myself.Besides it will be faster to get it done. That way I can ride the same day. Is there a break-in period for cams like for pistons?

Good job! Glad to hear that it went well. The only break in would be for the gears to settle into each other. I just bought a set of 95" jugs and pistons - going to do the top end before riding season starts - that should compliment the 26G I installed a couple of weeks ago.

Yes, there is some whine - I figure that a bit of break-in with good Red Line Synthetic might quiet it - but, it really isn't all that bad. The difference in torque makes me forget it - LOL. Now, it's time to install the bigger jugs - that's the easy part compared to the cams, and THEY were actually pretty easy.
