124078, Crank sprocket clearance
Posted by dj_lethrow, Feb-15-09 04:45 PM
Installed my crank sprocket today. Took a picture of where I slipped the feeler gauge in. The oil pump has a little lip, but I measured from outside of that lip as you can see in the picture and got .052 inches for clearance. Would this be acceptable or do I need to be measuring from the inside lip with a greater or lesser clearance?

I am not sure what spec is, but that looks good.

The book doesn't give the spec for that i dont think. I didn't see it just scanning over it real quick but i stuck a feeler gauge on my new engine on the stand and it was .052 also. Tight fit at .052 but it went in. So what mike said, it looks good! :thumbsup

The FSM does. Your book sucks.

I remember the spec being larger than .052, so you're fine. That's one of those things I tend to just eyeball.

Remeasured it today with the crank all the way to the side and its a little closer to .057 inches. Would this still be in the range of being alright?

Yes it does. But i agree with you, just eyeball it.
