8. Remove the pipe cleaner and measure the distance from the bend in the pipe cleaner to the lubricant level.

Specification
The distance between the bend and the lubricant level should be 15-40 mm (0.6-1.6 in).

9. If the measurement is greater than 40 mm (1.6 in), add lubricant until the level is between 15-40 mm (0.6-1.6 in) from the bottom edge of the fill plug hole. Use the proper fluid. Refer to Fluid and Lubricant Recommendations .

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.
