Countershaft Bearing Tab Washer for KTM 450/500 EXC-F 2008-2026 - 78033132000

This genuine OEM tab washer is designed to secure the countershaft bearing within the engine case. It ensures the bearing remains properly seated during high-stress operation, preventing axial movement that could lead to transmission issues. As an original part, it guarantees the precise fitment and material strength required for internal engine components.

Compatible with a vast range of models including the KTM 450 and 500 EXC-F, SX-F, XC-F, and Rally Replica from 2008 to 2026. It also fits Husqvarna FC 450, FE 450/501, FS 450, and FX 450 models, as well as GasGas MC 450F, EX 450F, and RX 450F Replica. Additionally, it supports older KTM 400 and 530 EXC/XC-W models and Husqvarna FE 390/570 series.

Constructed from high-quality steel, this tab washer is built to withstand the extreme temperatures and vibrations found inside a motorcycle engine. Its specific crescent shape and dual-bolt mounting design provide a secure mechanical lock for the bearing. Replacing this washer during a transmission rebuild is essential for maintaining long-term engine reliability.

When installing, ensure the mounting surfaces are clean and use the correct torque specifications for the retaining bolts. It is recommended to inspect this washer whenever the engine cases are split or the countershaft is serviced. Using a new OEM washer prevents the risk of metal fatigue or failure in the shifting mechanism.
