What Is the PTO Side of a Briggs & Stratton Engine?
PTO stands for power take-off. The PTO side is the end of the engine where the crankshaft extends outward to transfer engine power to the equipment's drive system.
Briggs & Stratton 795387 seals the crankshaft at this PTO-side opening on compatible engines.
What Does Briggs & Stratton 795387 Replace?
795387 supersedes Briggs & Stratton 791892 and 690947.
Older engine diagrams or service information may still reference one of those previous numbers. Where Briggs identifies 795387 as the replacement, use the current 795387 oil seal.
What Engines Use Briggs & Stratton 795387?
Briggs & Stratton 795387 is documented across multiple small-engine families. Verified illustrated parts lists include applications within engine families such as:
- 21-series engines
- 31-series engines
- 33-series engines
- 40-series engines
- 44-series engines
Documented examples include 215802, 31R907, 31G777, 331877, 33R777, 33R877, 406777 and 44T977 engine specifications.
These examples do not mean that every engine within those families uses 795387. Always verify the complete Model, Type and Code.
PTO Side vs. Magneto Side Oil Seal
Briggs & Stratton engines can use a different seal at each end of the crankshaft.
795387 is specifically the PTO-side oil seal. For example, several Briggs illustrated parts lists that specify 795387 at the PTO side separately specify 391086S for the magneto-side oil seal.
These seals should not be treated as interchangeable simply because both seal the crankshaft.
When Should a PTO Oil Seal Be Inspected?
Inspect the PTO-side seal when engine oil is visible around the crankshaft where it exits the sump or crankcase cover, or whenever that area is disassembled during engine service.
Oil around the PTO shaft does not automatically prove the seal is the only source of the leak. Inspect the surrounding sump, crankcase sealing surfaces and crankshaft condition before replacing parts.
