Hi i recently bought a 1996 xj from a guy on craigslist it needs a water pump which i can handle and he said it needed some kind of bearing in the oil pan or something like that i know this is little info but if anyone knows what it might be could you please try to let me know. Im a mechanic and i should know what it is but im only certified in FIAT'S

crank bearing?

That Jeep Guy XJMJ

...... is it the oil pan bearing????

dallas96xj

it might be the crank bearing,
i didnt know there was an oil pan bearing unless your just screwing with me.

Rod bearing, main bearing?

dallas96xj

how hard are those to replace am i gonna need to pull the motor?

fishtaconc

You dont have to, but you have to remove crankshaft... you decide

UJSLOST

No oil pan bearing! LOL They just pulling your leg.

why would it need crank bearings and a water pump unless he overheated it?

Crank bearings are easy though - just drop the pan. They rotate in and out (2 piece bearing).

There's a question. Anybody hear of slapping in a set of rod bearing inserts AFTER it sounded up and have it work out? Granted the journal has already ready taken a beating....

dukie564

I'd say a visual inspection of the journal surface would be in order to make that decision - if it was badly scored I'd say the efforts would be wasted

UJSLOST

No that will not work if the journal has taken a beating it must be machined and an oversize bearing will be used. (I think I understood your question, if not sorry)

UJSLOST

I was always taught if you can feel it with your fingernail then it needs machined.

Just was wondering if anyone gave that a go. I tried it years ago on an old 20R. I cleaned it all nice and smooth, but nothing I had in my tool box could make it round again! It was toast and stayed that way. (I did buy a new crank, but found another Celica. That crank is still in the box, rusting around here somewhere)
Just looked on rockauto, about $17+ shipping for 4.0 rod inserts. Or they sell singles.
OP, If you end up going that way, you can put Pastiguage at two spots 90* apart, (say 4:30 & 7:30), and get an idea how out of round it is.

i bought the jeep for 300$ i towed it to my house and was told it needed a water pump and some bearings that are in the oil pan so im guessing that was what it was
