Good To Know

Q: How many main bearings does the 1630 engine use? A: The 1630 three-cylinder engine uses a set of main bearings along the crankshaft, so confirm how many your rebuild needs before ordering. Q: Should main bearings be replaced as a set? A: Best practice is to replace main bearings as a full set during a bottom-end rebuild so wear stays even across the crankshaft.

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