DIFFERENTIAL OIL
Fill differential up to the top of the
diff cross-pins. DO NOT fill the diff
to the top of the housing.
TO ENSURE YOU HAVE THE SAME AMOUNT OF OIL FROM REBUILD TO REBUILD, DO THE FOLLOWING:
➊
Put the diff (without oil) on the scale and
check the weight (approximately 9.80g)
➋
Slowly pour oil into the diff and watch the weight.
LOW TRACTION 5 000cSt (HUDY #106450)
MEDIUM-HIGH TRACTION 10 000cSt (HUDY #106510)
SUPER-HIGH TRACTION 15 000cSt (HUDY #106515)
NOTE:
Softer oil increases rear traction, harder oil increases on-power steering.
LOW TRACTION 20 000cSt (HUDY #106520)
MEDIUM-HIGH TRACTION 30 000cSt (HUDY #106530)
SUPER-HIGH TRACTION 40 000cSt (HUDY #106540)
NOTE:
Softer oil increases steering, harder oil increases stability.

OIL
PROPER AMOUNT OF OIL IN THE DIFFS
Use a digital scale to measure the exact amount
of oil in the diff. Remember that during operation
the diff gets hotter and the heat may allow the oil
to expand. If there is too much oil inside it may
interfere with the diff operation and damage the
internal gears.
