Specs At A Glance

Good To Know

Q: How do I know if my PTO inner crankshaft oil seal needs replacing? A: Common signs include oil weeping at the PTO end of the crankshaft, low crankcase oil, or water intrusion found during a rebuild. Inspect the seal lip and casing for wear or hardening whenever the engine is apart.

Q: Can this seal be installed without splitting the cases? A: On most 1500 engines the PTO inner seal is serviced during lower-end work, so access depends on your specific teardown. Confirm the procedure for your model year before starting the job.

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