Setup and Installation
This bolt is typically used to secure a clutch or brake lever to its perch on a motorcycle or powersports vehicle. Proper installation is crucial for safety and function.
- Preparation: Ensure the lever perch and the lever itself are clean and free of debris. Inspect mating surfaces for any damage.
- Lubrication: Apply a thin layer of appropriate grease (e.g., multi-purpose grease) to the unthreaded shaft of the pivot bolt and the inner bore of the lever to ensure smooth operation and prevent galling.
- Positioning: Align the lever with the perch, ensuring any bushings or spacers are correctly seated.
- Insertion: Carefully insert the 90112-MEB-670 pivot bolt through the perch and lever assembly.
- Tightening: Thread the bolt into its receiving hole. Using a torque wrench, tighten the bolt to the manufacturer's specified torque value for your specific vehicle model. Over-tightening can damage threads or components; under-tightening can lead to loosening.
- Verification: After tightening, check that the lever pivots freely without excessive play.
Note: The specific torque value for this bolt will be found in your vehicle's official service manual. Always refer to that document for precise instructions.
Function and Purpose
