INNTECK Crankshaft Oil Seal for GAS GAS EC 250, EC 300 1997-2019

INNTECK offers this crankshaft oil seal for GAS GAS EC 250, EC 300 1997-2019. On a 2-stroke it keeps the crankcase airtight, which a steady idle depends on; on a 4-stroke it keeps the engine oil in.

Why replace this oil seal?

The benefits:

• Stop an air leak or an oil leak at the crankshaft.
• On a 2-stroke, restore a steady idle and consistent carburetion.
• An inexpensive part to change every time the cases are split.

Why choose INNTECK?

Innteck, the Italian motorcycle-parts distributor founded in 2004 in Piedmont and part of the Athena group since 2023, develops off-road wear parts under its own brand with a carefully judged price-quality ratio.

When should you replace the oil seals on your GAS GAS EC 250?

Seepage around the shaft, a dropping oil level or, on a two-stroke, an idle that creeps up on its own are warning signs. The seal is also replaced every time the cases are split.
