Specs At A Glance

Good To Know

Q: Will this O-ring fit my STS 900? A: It cross-references to OEM 92055-3740 for the 2001-2002 STS 900, so it fits those machines. Confirm your serial number before ordering.

Q: Are O-rings like this reusable? A: Once compressed, a used crankshaft O-ring can harden and leak, so replacing it during service is standard practice. It installs into the crankcase groove with a light coat of grease.

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