Good To Know

Q: What are the signs of a bad crank seal? A: Common signs include a lean running condition, loss of crankcase pressure, oil migrating into the combustion area, and rough or erratic running. A leakdown or pressure test can help confirm the seal is the problem.

Q: Does this kit replace every seal in the bottom end? A: This kit is focused on the crankshaft and crank oil seal positions rather than every seal on the engine. Review your service manual and parts diagram to confirm it covers the seals you need for your job.

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