      The INNTECK OS184 crankshaft oil seal is designed for YAMAHA YZ 250 and FANTIC XX 250 from 2001 to 2026. The crankshaft oil seal seals the point where the crankshaft passes through the crankcase. A hardened or worn lip lets oil through and, on a two-stroke, lets air in as well.

      Specifications

      • Brand: INNTECK
      • Manufacturer part number: OS184
      • EAN code: 41228004
      • Engine: 2-stroke

      When to replace it?

      • Unstable idle, revs hanging or rising on their own.
      • Gearbox oil level dropping, white smoke (clutch-side seal).
      • Oil or black marks on the ignition side.

      At every bottom end rebuild, and as soon as these symptoms appear.

      Fitting tips

      1. Drive out the old seal without scratching the housing or the crankshaft.
      2. Grease the lip and press the seal in perfectly square, lip facing the inside of the engine.
      3. Protect the lip as you slide it over the crankshaft thread or key.
      4. Refit the cover with a new gasket.

      Frequently asked questions

      Do the crankcases have to be split?
      Not always: on some engines, the ignition-side seal can be replaced without splitting the cases. During a rebuild, replace it along with the crankshaft bearing and seal kit.
