Good To Know

Q: How many of these should I order for a full rebuild? A: Order one for each connecting rod position you are servicing. Check your engine layout and replace all bearings that show wear together.

Q: Does this bearing need to be matched to a specific rod size? A: Yes, bearing selection depends on the measured rod journal clearance. Confirm the size class and serial number details before ordering.

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