Dowel through flywheel into crank? Hey all,
I'm sure this is a stupid question, and I'm surprised it hasn't been asked before, but I see a hole in the back of my crank and in the flywheel. Is there supposed to be a dowel there? I can't believe I've never asked this because if it's supposed to be there, I've been doing without for quite some time, and I'm putting down a respectable amount of power. Hopefully I haven't been risking a catastrophy all this time.
Thanks in advance!

That's where the Transmission input shaft goes. There is a pilot bearing in the end of the crank as well. When aligning the clutch, there is a tool that is inserted into the pilot bearing that properly aligns the clutch with the flywheel. After everything is bolted down, the tool is removed and the transmission is reinstalled.

Most likely the OP's engine is "internal" balance so I would assume his crank (and rotateing assembly) was balanced without the dowel.....so don't install one and line the FW up so it's hole lines up with the dowel hole on the crank.

If you were to use the dowel pin on an internally balanced motor, would it throw things off that much, in respect to balance???? Also, when you install the pilot bearing, I assume it should be flush with that particular hole in the crank???? And, which is better, bronze or needle roller pilot bearing???

pilot bearing face should be flush with crank end. DO NOT push it in to bottom of crank hole. There will be space behind PB///so you can use a tool to remove it.
needle vs bronze....you will get both opinions. Mine is needle
