Oil Pump Gear Backlash/Clearance

[Herezja]

Just wondering if anyone knows what is considered excessive or acceptable for the oil pump gear clearance on a 360. Putting my Jeep back together and there seems to be a little play between the oil pump gears (about .010). Just want to make sure its not too much.

Have you read the TSM about this? It gives a spec for end play between the cover and the gears and side play between the body and gears. There is no spec for clearance between the gears. You could inspect the gear faces for excess wear, I suppose. My feeling is that it does not matter, because one gear is driven and the other is on an idler shaft and working against the oil pressure. So the faces of the gears will always be against each other, other than the film of oil between them.

Thanks for the info. I don't have a TSM, but have been trying to bring myself to spend the money on one. Right now I make due with my Chilton's manual and there wasn't anything in there. I suspect that it doesn't really matter myself, just want to double-check.

Look at any TSM on the www.oljeep.com site - 1974, 1976, 1982. They all cover the 360. There will be no difference in this topic from year to year.
