Specs At A Glance

Good To Know

Q: How many bearings will I need for a full crankshaft service? A: The count depends on how many main bearing positions your 1630 crankcase uses and how many are worn, so check your service manual before ordering. Buying the full set for the crank is common during a rebuild.

Q: Do I need to measure clearances before installing new main bearings? A: Yes, plastigauge or a micrometer check confirms the oil clearance is within spec before final assembly. Incorrect clearance can cause early wear or engine damage.

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