1. Put the diff (without oil) on the scale and
check the weight (approximately 40g).
40g + 2.1g = 42.1g
2. Slowly pour oil into the diff and watch
the weight. Add 2.1g of oil into the diff. The
approximate weight of the diff+oil is 42.1g.
Do not overfill the differential.
If there is too much oil in the
differential, it may leak after
it cools down after use.
To enure you have the same amount of oil from rebuild to rebuild, do the following:
