So Nick says



So who is right?

I will open her up if it's not the more solid bearing. But I need to know for sure.
I read the quote not your post. You are OK sorry to scare you. It's a bitch when you are in a hurry and misread something!!

The only other thing might be the lifters. I think Harley said they should be replaced on the older EVO's at 25,000 or so. The newer "B" lifters are said to be better.

Something not mentioned, this bike has the old design pulley/nut/spacer/lock setup.

In `94 the factory came out with an updated setup which consisted of a new pulley (thicker at the spline area) a shorter spacer, and a lockplate, to keep the nut from coming loose.

Although not a perfect solution, the new setup is much better than the old one, which used a single bolt threaded into the pulley in the hope that if the nut backed off it would stop when it contacted the head of the bolt (it did not work, the nut would just shear off the head of the bolt and continue to loosen).

That's a good point. I have owned my 1990 FLHS from new and there were several things that went wrong during the first few years. I have never had problems with the front pulley, although the oil seal behind it leaked. I have not had any problems since fixing it. I had it done by a Harley specialist, so don't know if he fitted anything different from stock. I have an S&S 107 in the bike now and the tranny is still stock.

That stock crankcase seal on the primary side is single lipped and meant to keep primary oil out of the motor but it does weep motor oil into the primary. If you're running a wet primary you're not apt to notice it, But with a dry primary (ie, an open belt drive) you will. But in either case if the oil starts getting into your rotor and stator you will begin to notice charging problems. There is an aftermarket double lipped seal (seals both ways) and that seems to be the fix. If you notice oil weeping out where your voltage regulator is plugged into the front of the case, you can silicone it up to stop the leak, but that's just a band aid, as it means your alternator is also getting gunked up . . .
