Pilot Bushing Confusion-Need Help

Post  Cazador on November 21st 2017, 9:27 am

‘71 TJ motor’s going to have an NP435 behind it. The crank has two options for a pilot bushing. The outer step is a larger diameter than the inner step. I installed a brass bushing in the outer step but it protruded about 1/8” above the end of the crank. This worries me. I searched EVERYWHERE but couldn’t find a bushing to fit the inner step. The ID of that inner step just doesn’t match anything I could find: anywhere. What do you think about using the outer step bushing? Just seems like it should set completely into the crank and it doesn’t.
Would appreciate your insight as I’m very much a rookie; but having fun notwithstanding frustration at this point. Vic

That's right. And that's the outer "step", closest to the end of the crankshaft, that I was talking about. And the bushing I found that fits there protrudes about 1/8" beyond the end of the crankshaft on my motor. So two things: why? and is it safe to put a pilot bushing/bearing in that place and use it without worrying about it all the time?
