Rear diff capacity?

[WLM_RAMMAN]

What is the exact oil capacity of of the Dana 80 in the rear of the Cummins?... I can't remember what I read in the manual and I want to be sure to get enough 75W-140 for the change over.

I'm posting from memory here, but I believe the capacity is 7. 8 pints or not quite 4 quarts. When it starts running out of the fill plug, you will know you have enough in.

I just got through filling mine. I put in 10. 1 pints. I think it makes a difference if you have a 4X4 or not.

Thx guys... I only got 4 quarts, so I guess its order time again!

Out Of The Book

Okay, Vol. 1 page 0-6 says for 2wd 6. 8 pts** for 4X4 10. 1 pts***



** includes 0. 25 pts of friction modifier



*** includes 0. 4 pts of friction modifier



Hope this helps... ... ... ... ..... Pete

7.8 pints for transmission

The NV4500 takes 7. 8 pints of fluid. Regarding the 6. 8 pints for the Dana 80, I am glad that I changed to the Mag-Hytec cover. I'm running 14 pints in the differential right now. That has got to be much better for the axle and gears.
