Good To Know

Q: How many bearings do I need for a full rebuild? A: The quantity depends on your specific crankshaft configuration, so check your service manual to confirm the correct count before ordering. Ordering the right number the first time avoids downtime during reassembly.

Q: Can I install this without machining the crank? A: Installation should follow the clearance specs in your service manual, and any worn or scored crank journal should be inspected first. If the journal is out of tolerance, a replacement bearing alone may not restore proper oil clearance.

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