OIL SEAL 13x22x7 YAMAHA 93101-13800-00

Function and technical context

The 13×22×7 oil seal is part of the engine sealing system, sealing the area where the camshaft or crankshaft passes through the casing. Its mission is to prevent lubricating oil from escaping to the outside, maintaining the internal pressure of the system and avoiding losses that would compromise the lubrication of critical components. This seal works under constant pressure and direct contact with hot oil, which exposes it to progressive wear due to friction and hardening of the elastomeric material. Its failure allows oil leaks that not only reduce lubrication levels, but can contaminate the engine compartment and generate thermal stability problems.

When to replace this part?

Typical symptoms of a worn seal include oil stains on the base of the motor, visible dripping under the boat at rest, and gradual loss of lubricant level without apparent cause. This type of component must be inspected at each seasonal inspection and replaced if it leaks, since the lost oil does not recover on its own and wear is progressive and irreversible. Preventative replacement prevents offshore repairs and prolongs the life of items that depend on oil to function properly.
