Apply the gear oil through fitting (3). Fill with gear oil until the gear oil reaches oil level (4) at the top of the hex head on the fitting. Remove any excess oil. This will maintain a volume of air. Refer to Caterpillar Machine Fluids Recommendation, SEBU6250 for the appropriate oil viscosity that is suited to the ambient air temperature. The gear oil must be applied with a 7H-1680 Lubrication Pump or a suitable grease gun. Use SAE 90 API GL-5 gear oil, 85W90 API GL-5 gear oil, 80W90 API GL-5 gear oil, or 75W90 API GL-5 gear oil. The gear oil has excellent load carrying capacity.
Install plug (2) .Note: THE USE OF GREASE (MPGM) IS ONLY ALLOWED FOR A FAILED SEAL. THE SEAL SHOULD BE REPLACED AS SOON AS POSSIBLE. THE COMBINATION OF GEAR OIL AND MPGM IS NOT HARMFUL TO THE MACHINE.Earlier Version
