Do not overfill the differential.
If there is too much oil in the
differential, it may leak after
it cools down after use.
Use the following silicone oils included in the kit for initial settings:
FRONT diff:
5 000cSt
/ REAR diff:

#107865 HUDY Ultimate Digital Pocket Scale 300g±0.01g
To ensure you have the same amount of oil from rebuild to rebuild, do the following:
1. Put the diff (without oil) on the scale and check the weight:
- REAR DIFF approx. 39.30g
- FRONT DIFF approx. 40.10g
2. Slowly pour oil into the diff and watch the weight.
Add 2.70g of oil into the diff. The approximate
weight of the diff+oil is REAR DIFF approx. 42.00g
and FRONT DIFF approx. 42.80g
