My 1958 Massey Ferguson T035

Hello I just bought a Massey Ferguson T035 from 1958. It's in pretty good shape, and runs good, everything works, BUT I checked the tranny oil and its milky, I looked it up and it said the rubber boots were wore, I checked and they were severely worn allowing rain water to enter around the gear shift, I want to drain tranny and rear end and replace with new oil, When I drain it, Can I fill it up with diesel fuel to clean, and if so, do I run it and use the life and pto, Or just fill and drain. Or not use diesel at al to clean, I don't want to hurt the tractor.

You have now got one of the best tractors ever made, IMHO ! No complex systems to go wrong, easy to work on if needed, and there are still so many around
worldwide that repair part costs (eg, Perkins diesel overhaul) are about the cheapest of any makes!

I had several, all had the milky fluid when I got them, and I just r=drained and refilled.

And there are actually 5 holes or chances for water to get in . . . .

2 on the gearshift boots, a third if the gasket is missing or buggered on the oil filler plug, the fourth is the breather vent under the seat (the cover usually
gets knocked off and leaves a small hole open to the elements), and the fifth - the rubber boot on the three point top link hookup point at the rear.

And that one is a challenge to re-do properly!

I like to jack up the front when adding the tranny fluid to keep from overwhelming the front seals.

Funny, I bought a 59? MF TO35 recently and the transmission fluid was milky white too. I drained, put 4 gallons of used transmission fluid in I
saved from another tractor. Ran that for awhile, drained, and put another 4 gallons of used in. I plan to top that off, run it a couple months then
drain and refill. Apparently these tractors have a screen filter in the housing so clean that when you have it drained. Read about it in the owner
manual. Now I am working on fixing the sloppy steering.

I have a 1957 model TO35,
I just took the tractor out and broke up my truck patches, Using the tractor about as hard as I ever use it,
You want the transmission oil hot if you can get it hot before you drain the oil

Brought the tractor straight to the work shop and drained the transmission oil,
You will have about 8 gals of used oil, be sure to have drain containers available to accept that much oil,

It takes hours for the oil to drain out,

My advice: If the transmission lift system are working properly, then do not fix it, just drain the oil and replace with new oil,

What oil to use, you have no transmission oil filter, system was designed to use non detergent oil, so dirt particles fall out to bottom of sump and
will be drained out,

I replaced the oil with NAPA non detergent GL-1 90 weight mineral oil, what was called for in owners manual, but there may be other oils out
there,
Would like to have used 15w40 non detergent oil, but you cannot buy it over here, they do sell it in England, why we can not buy it I do not
know,
Note pour new oil in slow it has to travel into three different sump areas so it takes time to let it settle out,
No horse race here,

any idea when filters appeared for the hyd system ??
thanks.

Yes, but don't forget that you are raising the the oil level at the rear outer hubs or inner brake units if you have a tractor with dry disc brakes or shoes.
There could be a possibility for oil contamination.

Missed that it was a 35 but still applies.
