Correct Oil for SFA GBox and Tcase and Diffs

Post by Big D »

Hi All

What is the correct oil for Gbox, tcase, front diff and local (gearmax) rear diff?

And how much of each.

Thanks

Thanks Mark

But I need more Help

The Workshop Manual says:
Gbox: 75w90
Tcase: 75w90 or API GL5 or GL4
Diffs: 80w90 or SAE 80W

Mayfair Gearbox (they redid my Gbox) says:
Gbox 75w90
Tcase 85w140

Trail Gear (suppliers of my low range gears) says:
Tcase : 80/90W GL5 wees

Gearmax (local diff supplier) says
Diffs: 85w140 GL5

Any Help on chosing the correct one?

The Workshop Manual says:
Gbox: 75w90 The owner's handbook says EP SAE 80W-GL4 Transmission oil
Tcase: 75w90 or API GL5 or GL4 You can use the same as the gearbox.
Diffs: 80w90 or SAE 80W The owner's handbook says ISO 460 85W 140 GL5 for rear diff (local G/max) ---- EP 90 GL5 for front diff (import)

Mayfair Gearbox (they redid my Gbox) says:
Gbox 75w90 Same as what the handbook says.
Tcase 85w140 Maybe they feel a diff oil is better .... can't do harm if that's what they used.


Trail Gear (suppliers of my low range gears) says:
Tcase : 80/90W GL5 wees Follow their reccommendation.

Gearmax (local diff supplier) says
Diffs: 85w140 GL5 Same as what the handbook says.

Any Help on chosing the correct one?

I've just put 85w140 (Shell Spirax) in my front diff. Should I drain it and put in 80w90 (or EP90)?
