Question 1

What does the '-20' in the part number mean?

Accepted Answer

The -20 indicates this is a 0.020 inch undersize bearing set. This means the bearing is designed for a crankshaft that has been machined 0.020 inches smaller than the standard size. Always measure your crankshaft before selecting bearings.

Question 2

How should I install these bearings?

Accepted Answer

Refer to the manufacturer's installation instructions for proper procedures, including any specific torque specifications or sealant requirements. Proper installation is critical to ensure the longevity and performance of your engine.

Question 3

What other parts should I replace when installing new main bearings?

Accepted Answer

When overhauling your engine, it's best practice to replace all the bearings at the same time, including the connecting rod bearings. You should also inspect the crankshaft for wear and have it machined if necessary. Always use new gaskets and seals when reassembling your engine.
