Failure to follow these precautions may result in personal injury and/or damage to the vehicle or its components.

    Important: You must use a brass feeler gauge in order to obtain correct measurements. A steel gauge will not conform to the guide and will not provide correct measurements.

  3. 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 3 pounds of force.

    4. 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.
