Here it is on another forum, with pics ...
How to Install Cam Gears in your IronHead
http://xlforum.net/vbportal/forums/s...d.php?t=239641
It sounds like you do not have the factory service manual 99484-78 or the factory parts catalog 99451-78B. It is essential to have both of these in hand when working on these old bikes, especially when doing any engine work.
TDC is irrevelant to installing cams. You must have the pushrods out. You do not have to take off the heads or the rocker covers. Make sure that you have all 4 pairs of marks are lined up beginning with the pinion gear mark.
Did you have the pinion gear off? There is a specific way that it must be re-installed.

The Pinon gear is still engaged...
I have the service manual for the bike..I am 20 years old and just making sure so i dont mess anything up..I really appreciate the help,Thank you.
When disassembling the pushrods do I have to make sure all the valves are closed? and It does not matter where the pistons are in the cylinder?
I understand lineing the timeing marks on the gears.. I just have spent alot of money on this bike and am down to my last dollars and the bike is about ready..

You do not have to remove the cylinders and heads. The manual gives you the steps to follow.
It is easier to have the valve fully closed to remove a pushrod. You do this by rotating the engine while watching a particular pushrod. When it gets to it's highest point of lift......Stop. Now go to the like pushrod on the other cylinder and turn the adjustment bolt inward. This valve is fully closed.
Do the same with the 3 other valves. You're going to find that a couple of pushrods are going to be 'tight' when removing them, even though the adjustment screws are turned all the way in. It's just the nature of the beast.
Be certain to replace all 12 cork washers in the 4 pushrod tubes when things go back together.

With the back wheel off the ground, the transmission in 4th gear, rotate the engine until one lifter is fully up. Then remove the corresponding pushrod on the other cylinder. Repeat until they are all out.
Just save enough $s for fuel and oil.

It is not necessary to remove the tappets. What i do is attach a cloths pin [or elastic or whatever] to each one to hold them up out of the way.
IMO it is not necessary to do anything with the cam gear end play. This is one of those controversial topics - some guys say you should shim the cams others do not. Here on my SkyDrive account is the HD service bulletin about that. Click on this link then click on DownLoad ...

Hey Dynaman,anythings possible when you're just learning. Will a cam cover come off with pushrods installed? Yes. Can you pull a cam gear out with the tappet at lowest point? Yes. When a novice takes something apart anything is possible, when a novice who is unsure of the right approach first works on something they can make misstakes, most people learn from the missteps that they've taken. Most people do learn, if someone is willing to politely point out their missteps and let them know when they've done right.
It's pretty obvious you've never seen that side of looking at things, shame really cause at times you actually sound like you might know a thing or two, but then there is the rest of the time.
