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.
Tighten
| • | Tighten the pump to housing long bolts to 12 N·m (106 lb in). |
| • | Tighten the pump to housing short bolts to 10 N·m (89 lb in). |
Important: A brass feeler gauge needs to be used to ensure correct measurements are obtained. If a steel gauge is used, the steel gauge will not bend to conform to the guide and will cause incorrect measurements.
| 4.1. | Inserting a 1 mm (0.040 in) brass feeler gauge between the chain guide and the chain. |
| 4.2. | Press the guide against the chain. Use about three pounds of force. |
| 4.3. | Tighten the chain fastener bolt. |
