Briggs & Stratton 795387 Crankshaft Oil Seal (OEM Replacement)

Stop oil leaks at the source and protect your engine from costly damage with this genuine OEM Briggs & Stratton crankshaft oil seal (Part #795387). Designed to create a tight seal around the crankshaft, this component prevents oil from leaking out of the engine’s lower end during operation.

Why This Part Matters

A failing crankshaft seal is a common cause of oil leaking underneath your engine, especially around the pulley or PTO shaft. Replacing it restores proper sealing and helps maintain correct oil levels.

Common Signs You Need This Seal

• Oil dripping from the bottom of the engine
• Oil buildup around the crankshaft or pulley area
• Oil spots on the ground or mower deck
• Engine runs low on oil without an obvious top-side leak

Product Features

• Genuine OEM Briggs & Stratton part 
• Designed for a tight, leak-free seal
• Built to withstand engine heat, pressure, and rotation
• Helps prevent oil loss and internal engine damage

Fits

Compatible with many Briggs & Stratton engines, including select:

• Intek Single Cylinder engines
• Intek V-Twin engines

Installation Notes

• Typically installed behind the engine pulley or PTO shaft
• Removal of the pulley and surrounding components may be required
• Always inspect the crankshaft surface for wear before installing a new seal

Why Fix It Now

Running your engine with an oil leak can quickly lead to low oil levels, overheating, and severe engine damage. Fixing a leaking seal early is much cheaper than replacing an engine.

Pro Tip

If oil is leaking from the top of the engine, the issue may be a valve cover gasket instead. If the leak is coming from underneath, this crankshaft seal is a likely cause.
