Good To Know

Q: Why are alignment pins necessary during engine installation? A: They ensure the engine and transmission are perfectly concentric, preventing input shaft binding and premature seal failure.

Q: Can these pins be reused during future engine teardowns? A: Yes, the durable steel construction allows these pins to remain in place or be transferred during subsequent rebuilds.

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