Crank shaft end float.

(1/2) > >>

Vince Caldicott:
Does anyone know what tolerances are acceptable for crank shaft end float on a 427 side oiler?

minimans:
I have .008 to 0012  on a street build

minimans:
Factory spec is .004 to .0014

Vince Caldicott:
Thanks for the reply, I have quite a bit more than that. Is there an easy fix?

'Easy'...
   Well, first you have to identify why you have greater clearance than stock.  Worn bearings (easy to fix, but why are they that badly worn?) or worn crank (not so easy to fix).
   What sizes are your crank journals, and how badly worn are the shell bearing surfaces?  If the whole shebang is worn, a grind and new bearing shells shoud fix it.
   If it's crank damage, you need either a set of shells with oversize thrust faces or a wider crank journal to take up the excess.  I don't know if anyone makes plus sizes in thrust bearings for the FE.  If the crank is worn/damaged, you need to think about either a new crank or metal spraying to build up the lost material and machining back to size.
   How much out are you?
   Never start an engine with your foot on the clutch...
