I changed the bevel box oil yesterday at 2800 miles. I bought Morris XFX 80W/140 LSD oil from Classic Oils. Did the whole job from underneath. After a run to warm it I jacked the car up & drained the oil. Very black & did not seem that much came out. refilled with diesel fuel through the level plug hole & let the engine turn the wheel for a brief time. Drained & repeated with diesel. Filled with Morris oil again letting engine turn the wheel. Drained & refilled with Morris oil.
The drained oil was still dark so I'll put some miles on & do it again without the diesel. On a run today the box was maybe a bit quieter.
I bought a suction/discharge pump from Classic oils but useless for the job as the hose will not go in the level plug hole nor would the spout on the oil container. I used my small trigger pump oil can for filling. Take care not to loose the dowty seal off the level plug.
