A coating is applied to the new intermediate gear wheel which sets the correct tooth backlash through wear.
When intermediate gear wheels are coated to areas around the circumference, a white spot is fitted to ensure correct installation position.
The intermediate gear wheel without white spot is fully coated around the circumference.
Caution
When installing the intermediate gear wheel ensure that the thrust washer is seated correctly

Who makes these pages, and how
TorqFix was built by a mechanic — after a 2,700 km drive with five roadside repairs that no diagnostic tool could explain.
The figures on this page come from manufacturer workshop documentation and are shown as they are. The page is assembled automatically from that data — it is not written by an AI. The AI works in the chat, where it answers for your specific car. It writes nothing here.
Variants of the same model differ. Cross-check torque against the factory manual for your engine before final tightening.
