88pathoffroad Posted December 3, 2007 Share Posted December 3, 2007 Chilton's says no need, pack the pump full of petroleum jelly first, then start 'er up when ready. Link to comment Share on other sites More sharing options...
unccpathfinder Posted December 3, 2007 Share Posted December 3, 2007 hmm so you have to do some tearing down for an engine thats been pulled for a while then... Link to comment Share on other sites More sharing options...

unccpathfinder Posted December 6, 2007 Share Posted December 6, 2007 Let me try to remember to check the FSM to see if it has a procedure...but I do know the JY i used to work at had 3 oil pumps fail or not prime after a swap Link to comment Share on other sites More sharing options...
Roost Posted December 6, 2007 Share Posted December 6, 2007 (edited) Yes you have to prime the oil pump before you start it. If you don't, your looking at investing another chunk of change. Use some white lithium grease and pack it into the hole that is about the size of your pinkie finger. Use your finger to stuff it in until it comes out a very small hole on the other side. Trust me when I say it seems like it takes a lot of grease, but $5 worth of grease or $200 for a new oil pump and then the grease?

madhatter_xe Posted December 12, 2007 Author Share Posted December 12, 2007 (edited) I was thinkin more about this b/c my engine is already in and there's no turning back...and I figure if i'm just dropping in a used engine wouldn't it be the same as somebody letting a car sit for 6 months and then firing it up?

Your choice, of course, but if it is a new oil pump, I would HIGHLY recommend priming it with the grease now and avoid the 200 bones to replace it later.

Roost Posted December 12, 2007 Share Posted December 12, 2007 Another note that just occurred to me is that you will need to take off the cap that is about 21mm to see when the grease comes out through that little pin hole while you stuff it in with your pinkie.
