PROX countershaft seal kit for SUZUKI RM 250, RM-Z 250, RM-Z 250 E from 2003 to 2026

PROX offers this countershaft seal kit for SUZUKI RM 250, RM-Z 250, RM-Z 250 E from 2003 to 2026. The front sprocket drives the chain. Its shaft passes through the case and an oil seal (often with a bush) keeps the oil in.

Why replace this seal?

The benefits:

• Stop an oil leak behind the sprocket.
• Protect the gearbox from running low on oil.

Why choose PROX?

ProX, the Dutch engine-parts specialist since 1975, has its parts made in factories that also supply the manufacturers: OEM quality at a more affordable price.

When should you replace this part?

Seepage around the shaft or a dropping oil level are warning signs. The seal is also replaced every time the cases are split.

Specifications and fitting tips

• Application: Countershaft
• Designed as an upgrade over OEM parts

Cross-Mania tip: Fit the seal square with a greased lip and check the running surface on the shaft: a worn surface quickly wears a new seal.

• Gearbox oil : LIQUI MOLY 10W30 1 L · LIQUI MOLY 1 L
