Good To Know

Q: When should the wrist pin bearing be replaced? A: Replace it any time the top end is apart for a piston or ring job, since they are inexpensive and wear with the piston pin. A: A rough or loose feeling when you spin the old bearing by hand is a sign it is due for replacement.

Q: Does this bearing fit both the 1992 XP 580 and 1993 SPX 580? A: It is listed for both machines and cross-references OEM 290832320. A: Confirm your engine and serial number before ordering to be sure of fitment.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
