We had excessive thrust play in out 9h d353.
We pulled the engine to find the thrust face to the rear of the crank chewed up.
The bearing is a 1n4335 that's stamped also with 5nedn unan 0.63 os 0.63 us
From what I found this bearing is listed as a 25 over 25 under or is it a 63 over/under?
Do they make oversized thrust bearings or should we be looking for a crank?
Is it possible to have the crank welded up and ground back to spec on the one thrust face?
I'll be calling a bunch of crank shops tomorrow to try and figure out the best possible route on this one.
The motor is still half in the frame so I can't really mic the crank or block. We were hoping for just a bearing but now it's looking like major surgery.
Any advice would be much appreciated.
