Crank pilot

Does anyone know what size crank pilot is on the steel 429 truck crank
, I'm hoping it is 1.375, but I haven't measured it.

mine is 1.850,sorry .i dont know about all them.what you got goen on?

I believe all of the early stuff has a 1.850" pilot size. IIRC, after 1972 is when they went to the smaller 1.375" pilot size.









Doug...

I got a lathe we can GIT-R-DUN , gonna rain all damn weekend

I called Coan, one of the tech guys said to use it as is, just put it together, and tighten the flex plat to the convertor, and go with it, you guys agree, or should I pull it back apart.?

Get with Mike (BigDog466)....he can hook you up....all you need is enough room between the front of the converter and the crank to slide the sleeve in....don't have to pull it all out. He is right....gonna' rain all weekend.
P.S.-I have ran without one before for a while...prolly not a good idea though...lol.

Has he got a shop, or someplace to do it, I would tow it to his place?

I don't think you would need to take it there....just take some good measurements with a set of calipers and he should be able to fix you up....or at least get you close enough that a little polishing will make it slip in....he is pretty sharp.

you dont want to run it without the ring on it.the best thing that would happen is the bushing in the pump gets beat out,then the leaking starts,and you dont even want to know the rest.
