Kohler oil seals pack of 2 (25-032-06-S) OEM crankshaft seals — fits CH/CV/KT series, factory spec

Genuine Kohler oil seals (part #25-032-06-S) — sold as a pack of two OEM replacements for a wide range of Kohler small engines.

Keep engines running reliably by replacing worn crankshaft seals with factory-spec parts. These two authentic Kohler oil seals are supplied by an authorized Kohler dealer and are manufactured to match original equipment tolerances. They fit many common Kohler single- and twin-cylinder engines used in mowers, pressure washers, generators, and other power equipment. Installing correct OEM seals helps prevent oil leaks and simplifies maintenance because they are built to the engine maker’s original dimensions and material specs.

How do I identify the correct part for my engine?

Locate the engine’s model, spec and serial numbers stamped on the engine housing or data plate. Those numbers let us verify fitment and prevent ordering the wrong part.

• Find the engine data plate near the recoil starter or blower housing.
• Note "model," "spec," and "serial" exactly as shown and include them when asking for lookup help.
• Contact the seller or Kohler parts department with those numbers for confirmation.

What are the benefits of using genuine Kohler oil seals?

OEM seals are produced to the same tolerances and materials as the original components, reducing fitment issues and premature failure. Using genuine parts keeps warranty and service records consistent and minimizes downtime during repairs.

• Exact dimensional match minimizes crankshaft wobble and leaks.
• Material choices resist oil, heat, and typical wear for the engine family.
• Sold in a convenient two-pack for twin-seal applications or spare parts storage.

How should I install and maintain these oil seals?

Proper installation extends seal life: clean the shaft and bore, use light lubrication, and seat the seal evenly without distorting the lip. If you’re not comfortable with engine teardown, a qualified service technician can install the seals quickly.

• Clean sealing surfaces thoroughly and inspect crankshaft for nicks or grooves.
• Apply a film of engine oil on the seal lip before pressing it into place.
• Use a seal driver or appropriate socket to press the seal squarely to the specified depth.
