Gear Lubricant Filling Instructions
1. Attach a Leakage Tester to the vent hole.
2. Apply an air pressure of 69 ‑ 103 kPa (10‑15 psi) through the vent hole. The pressure should remain steady for at least 15 seconds while alternately applying two to three
pounds of force to the top of the shift shaft in the fore and aft direction.
3. Inspect the fill and vent sealing washers for cuts or abrasions. Replace if necessary.
4. Clean any metal debris from magnet on fill plug.
IMPORTANT: Never add lubricant to gear housing without first removing vent screw, or gear housing cannot be filled because of trapped air. Fill gear housing only when housing
is in a vertical position.
5. Slowly fill housing through bearing carrier fill hole with High Performance Gear Lubricant until lubricant flows out of vent hole and no air bubbles are visible.
