[T2] pilot bearing and main seal

[Patrick Harris]

Run a tap into the bushing. Remove the tap. Screw a bolt into the tapped bushing.  As the bolt "bottoms out" continue turning it and the bushing will be pushed upward, out of the crankshaft. Tap size and length of bolt are determined by you. Yes, this destroys the bushing.

I've remove them carefully with a small chisel or punch by driving one edge of the ring towards the middle of the circle. Otherwise an actual pilot bearing puller works amazingly. You can even pop out a good pilot bearing without damaging it. The tool costs something like 60-40. I just borrow one from a local shop.
> I bad pilot bearing can take out the main seal. I've never had any issue pulling the main seal. They always came out with relative ease using a flat head screw driver and levering off the center rather then trying to drive it between the outside edge of the seal and the case.  I have discovered deep gouges in the case from other people's efforts. If it is deep I like to clean it well and use a wee bit of jb weld to fill the void. Then sand it smooth.

I thought I could use a razor to shave if the unwanted foam. It is very hard to cut, sticks to everything you dont want it to and pops off of the areas where you want it. There are better sound deadening and insulating  products out there in my opinion.
