RE: 26G Cam Install Update
About the only thing you really need is an inner bearing remover/installer. All else is doable without the proper tool. I did my 26g and only used the inner bearing remover/installer thatI bought for $85. I did have alignment pins also.[/align]

RE: 26G Cam Install Update
I rented the Jim's inner bearing removal/installer tool -- man it worked great. Probably made this the easiest part of the entire job.

RE: 26G Cam Install Update
Hi Taterdog,
Just got my 26G's in the mail today and will be hopefully putting them in this weekend. This has been a Great thread to read with a ton of advise from all. While I had mine apart I decided to order a new Feuling Oil Pump and Feuling Tappets, which should be in tomorrow. Can you give me more info on the Oil Pump alignment pins and how they work. The manual just talks about rotating the rear wheel while you tighten the pump bolts. Last this I want is to do isfry that new pump because I have it out of whack. Also, was thinking about do the same thing you did with the freezing and heating of the part to press them together, how hot did you set the oven and leave them in for??
Philm, Your tips on dumping oil down the tappet blocks and pre-cranking to motor are very good tips. You Rock...

RE: 26G Cam Install Update
Hey, tdaffner, sounds like you've got a good weekend ahead of you! 
I've read different things regarding using the alignment pins. Basically you should be able to install them in two diagonally opposite bolt holes, say 3 and 4, then just install bolts in holes 1 and 2, snug them down, remove the pins, and install bolts in 3 and 4. I also read that it doesn't hurt to rotate the engine while installing the alignment pins, so for whatever reason that's what I did just to make sure. You might want to check out the following link to Harley Hogs Lair site. He also installed the geared cams and Fueling oil pump and has very good pics on the installation.

I heated my parts for 25 to 30 minutes at 325, and usually had them in the freezer about ten minutes more. Everything worked great, but be prepared to work quickly when you do the assembly. I didn't have any problems, but parts tightened up pretty quickly once assembled. And be sure you get the alignments correct. Since the cam plate is aluminum, and its expansion coefficient must be greater than steels, installing the bearing/gear/cam assemblies into the plate was very easy, as it took a while for the aluminum to shrink back down for a tight fit. From what I hear, many people use this method and some prefer it since it doesn't side load the bearings. Made since to me. Good luck with your project.

RE: 26G Cam Install Update
Hey Taterdog,
Thanks for the advise and the link on the Feuling install. I am going to see if I can find a set of alignment pins, if I have to order them from Jims it sounds like it would still be worth the wait over messing up that new Fueling Pump. I also ordered the PCIII from Jamie at FuelMoto yesterdayand got the new D&D Fat Cats last weekend. Can't wait to get it all together.

RE: 26G Cam Install Update
The Jims tool and the HD tool are good, but the only thing that I didn't like about using them as opposed to the one I bought made by a machinist, was that with the plate attached to the cam chest you can't see what you're doing. You can see in the pic that the combo tool that I had used lets you see everything.
You can unload the tensioners with a open end wrench and stick a small allen wrench through the hole to hold them open. You don't need the gear lock either to remove the stock cams, you can put the bike in gear and push down on the rear brake pedal while removing the bolts. You also can successfully align the pump without the pins by having a buddy spin the rear wheel while alternately tightening the two bolts where the pins would be. Here's a tip that I found useful so you don't mix up the cam plate bolts with the cam cover bolts
Then of course the freezer/oven works well if you don't have a press, here you see cams fresh out of the freezer
I also like using a straw in the spark plug hole to help me find TDC when rotating the wheel while bike is in gear.

RE: 26G Cam Install Update
Yeah, I had seen a tool similar to what you used to install the inner bearings and thought about trying to find one, but I had absolutey no problem using the Jims tool. I did shine a flashlight into the cam chest and was able to see just well enough to verify the bearing was aligned with the bore, which it was both times. I think either works just fine.
I also used the straw in the cylinder to verify TDC, and rotated the compensator nut to rotate the engine -- either I'm getting old or my rear wheel is a b**ch to turn in 5th gear.
