Some technicians may find that when removing the transfer case fill plug, it cannot be removed or is difficult to remove because of interference with the external rib on the transmission case. If you encounter a vehicle where the transfer case fill plug contacts the transmission case, remove material from the transmission case rib starting at the fill plug head, not more than 3 mm (0.118 in) by 25 mm (1 in), using a file or suitable tool to create clearance.
Caution
- Do not attempt to remove the remaining portion of rib adjacent to the plug head when the plug is removed because marring of the plug sealing surface will cause a leak.
- Ensure all debris from grinding/filing is removed prior to removing and reinstalling the fill plug.
