Good To Know

Q: How many bearings do I need for a full crank rebuild? A: Most crank rebuilds use multiple main bearings, so check the service manual for the exact count on the 1630 engine. Order the number your build requires.

Q: Does this bearing need to be pressed in? A: Crankshaft main bearings are usually installed with a press or proper driver tool and may need heat or chill fitting. Have a qualified shop handle the install if you do not have the right equipment.

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