80-140

[miner09]

Is 80-140 gear oil to heavy for F40. I can't find 90 wt in a 5 gal. can. I can get it in qts.($5)Everyone has the 80-140.($55 for 5 gal) Only for show and will not be running it in cold weather. Will power lift work OK with heavy oil.

You can get 80-90 at almost any auto supply and Tractor Supply. The price runs about the same as 80-140.

Use 15W30 or 40 engine oil for best preformance all year round! All the many, many Massey Fergusons on our side of the big pond run on nothing else and they all live to tell the tale!. 90 weight or any other oil has never been specified here in my time working with these transmissions/Tractors.

That oil you mention is far too heavy, while you could use it in the transmission, it is the hydraulics that you have to consider, it is far too heavy and would cause the control Valve to stick and could also cause too much pressure to be developed and that could cause parts to crack due to the pressure. The oil that you should use now all year round and it is OK in hot or cold climates is Multi-grade 10W/30, this will remain fluid down to -25 and it is a good oil to use for the transmission because of how it is blended, it has anti-wear properties which is a big help on these hydraulics. Change the oil every 12 months and only when it is hot, leave it draining over-night and then refill 2 gallons at a time leaving some time before you add the next lot or the level could rise too high in the transmission and run through into the Clutch Housing. It doesn't matter that you are not using it in a cold climate, this oil is good for any use. A thinner oil is always better than a thick gooey one for hydraulics and it will spray around the inside which will help to prevent rust and condensation when it is standing long periods.DON'T use diesel or Kerosene to wash out the interior of the transmission as you can't drain it all out due to the shape of the floor of the housings, just drain it when hot..John(UK)....fergusontractors@hotmail.com

NAPA has the 90 wt. GL-1 oil. PN 65-205 (5gal. bucket) 65-201 one gal. jug.

They may have to get it in from the wearhouse.
 

[Jeff-oh]

Just re-checked the PN's are still correct.

This goes back to the threads a few months ago about what to pour in there- the 90 'mineral' is more like an engine #30, which I suppose is why 15w-40 is now acceptable to put in, but the 80-140 you mention... is the old fashioned standard transmission/ differencial oil... small bottles had the cone shaped cover do get into the diff plugholes, it's more of a syrup than an oil, nope. I wouldn't put that in there nope.
After dealing with the sheared bolts in the diesel and looking at the welding job someone did on the TO35 cover..... nope.
Go buy a pail of - OK 2 pails- of 15w40, you will have 2 gallons left for an engine oil change, and atleast nothing will break due to wrong fluids.

i buy my 90 weight gl-1 fergy trans/lift oil at napa.
best price i have found and they sell it by the gals.

right stuff for your brass or bronze bearings in your trans,

remember: it the bearings in the trans that need the right oil!!!!!!!!!!!!!

what good is a tractor with a good lift system if the bearings in the trans are out?

Maxwell, if 15W30 is good enough for tractors over here it will do in America,plus you have the benefit of instant hydraulics in winter. Bearings and bushings are not a problem in the 35/40/65 etc, maybe in the TE and TO range there was an issue. Micky, a couple of drums of 15W30 will sort out your hydraulics and a couple of engine oil changes also.....
