CHANGING FLUIDS ON AN 841 (801) POWERMASTER

For oil.. Depending on your temp range, and oil pressure.. you might be able to use anything from sae 30w to 40w.. or a 15/40 or 20/50

Unit has 3 sumps inthe rear.. HYDS, TRANS and DIFFY... all 3 can use CNH M2C134D.. a thinnish UTF type oil ( generic UTF meeting the 134d oil will work ).. Or yuo can used gear oil in the trans and diffy, and aw 32/46 in the hyds.

If your seals leak between the 3 sumps.. use the UTF oil.

Crankcase fill at the breater.. Trans fill by the shifter, level plug on left side.. Hyds fill on front of hyd cover.. has dipstick.. Diffy fill on rear of tractor.. level check on lower left axle trumpet... All drains along the bottom from front to rear..

i seem to remember the diffy being 8qts.. and 6 each for the hyds and tranny.. Mind you.. My book is at home.. and I'm at work.

Both TSC and NAPA will have your oil filter available in a reference book.

Spin on is a fl-1 ( napa 1515?? )I think.. standard ford filter used forever.. But if you have a canister.. stick with it... NO reason to change.. My NAA has the spin on.. the 660 has the canister.. Both make a mess when changing.. And the canister is a bit tougher to resist rocks kicked up on it... I've actually seen spin on filters leak due to can perferation from a thrown bit of debri from a mower..

I *believe* the canister insert is a napa 1004.. again.. I'm not near my book.... Both NAPA and tsc hwill have a application chart though...

Also, my OPINION is that the trans and diff should be 80w90 or 75w90 gear oil. The new tractors all use the thin stuff, but they were made for it. The old iron was made for the thicker stuff to fill the clearances.

Like I said, it my opinion, others will have equally valid opinions. Mine just happens to be supported by the original manuals. Why change? Unless you have leaks between the compartments....
