Hey guys I have to put in a new crank i could use some help? So i had a knock in my 92 xj so i put in all new mains and rod bearings go figure it only lasted about 1hr till the knock came back. So im going to just put in a new crank kit. Does anyone know of a good kit to get?

thanks

Here's the problem. When a bearing like that wears out its also worn out the other piece. You need to measure how much difference you have from the stock measurement.

 

Most people choose to have the stock crank reground to ture it up and then run an oversized bearing. And that would only be if the block and rods are perfect- meaning that a bearing hasn't spun and damaged the block or rods.

So it's probably best if you contact a good machine shop in your area and price both options. They'll be able to provide you with the information regarding a crank 'kit'.

 

also forgot to say when i put in all new bearings it was already .010 over, someone else was already down there messing with it. That is why i was thinking about the crank kit but sounds like im just gonna have to pull it out and take it to a machine shop and see what they say. thanks everyone for the help.
