  1. Install the balance shaft chain tensioner.

    2. Important: A brass feeler gauge needs to be used in order to ensure correct measurements are obtained. If a steel gauge is used, it well not bend in order to conform to the guide and it will allow for incorrect measurements.

  2. Adjust the balance shaft drive chain tension by inserting a 1 mm (0.040 in) brass feeler gauge between the chain guide and the chain. Press the guide against the chain using about three pounds of force.

    3. Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.
