MF 35 tranny fluid

crazy as a mf

New User

Bought this '62 model 35 last year and changed the milky tranny fluid right away using Tractor Supply brand travelers Hi-tran. I want to change it again now to get any grit or impurities that was left the first time. My question is should I use the Hi-tran specially made for older tractors such as this, this time around? Supposed to be better on the brass parts from what I understand. I used the regular stuff the first time that I use in my newer stuff.
 
check your manual.
I have a 1957 model to-35 and it has bronze bearings in the trans.

You want to protect those transmission bearings. My older machine came with GL-1 mineral oil, they sell that oil, at a reasonable price, at napa or they can order it.

some use 10w40 oil in the trans/hyd system. I guess the new oils will protect the bronze transmission bearings.

just remember you must use an oil that will protect those bronze bearings in the transmission, if your tractor model still has them.

i assume they got smart and did away with bronze bearings in the newer tractors.
 
You should use GL-1, AKA "straight mineral oil" in your 35.

Once ubiquitous, this is becoming a bit more difficult to find.

Look for the GL-1 rating or oil marked "yellow metal safe" (SOME more modern GL-4 and GL-5 oils are marked such and are better alternatives) or Ford Transdraulic.

Such oils are available at your MF dealer, NAPA and SOME farm stores.

If you want to do it right, remove the inspection covers and the PTO shaft and spend a couple of hours with a solvent filled garden sprayer, paper towels, etc., cleaning the sumps. You will likely find about 1/2" of sediment in the bottom.

John(UK) over on the Harry Ferguson forum swears by 10W30 not only for protecting the yellow metal but also because it stays fluid to a lower temperature than the GL-1. Having said that I did put GL-1 in my 202 which I bought from Napa, they had to order it but it was there overnight. Even in warm weather that stuff is thick and sticky, I can't imagine how it would be at -20. I don't plan to use the 202 much this winter as I have a TO-35 that I'm preparing. I will be putting 10W30 in it as it will be used in colder weather for snow plowing etc.
 
I had removed the pto shifter cover when I changed the oil and found lots of sediment / gunk as you mentioned. I don"t know the history of this tractor nor of previous maintenance, however when I went to clean the strainer type filter I noticed it was wire tied (as is normal) in a fashion that looked to be original from the factory. Of course it was gunked up badly and the hydraulics barely worked prior to the cleaning and new oil. I now have a new strainer on hand and want to change the oil once again and install it. This is a "62 Diesel Deluxe with the Perkins and multi-power. The multi-power is froze up it seems but I will tackle that another day. Paid $500.00 for it last year and gotten to really like this old tractor. The working tach shows 34XX hours and still starts and runs well. Since I"ve owned it has been used on a five foot bush hog and in the hay field pulling tandem rakes.
 
My tractor is similar 63 35x. The multipower wasnt working and it turned out to be the valve in the bell housing was stuck in low and the bracket in there was loose and the lever to valve therefore not operating. I have it all back to gether and the multipower is working fine. I am getting some oil at the throw out bearing which makes me think the sealing rings (replaced) in the input shaft are letting some oil passed when in high multipower.
 
The strainer can be unwired, removed, cleaned, replaced and rewired through the inspection covers but it is time consuming.

You may want to semply remove the lift cover to properly clean the strainer and the sump and renew the lift cylinder bore and rings while the cover is off.

A few years ago I did this to a 61 35 Perkins Deluxe and a 64 FE 35 Perkins that I owned at the time. It is not a difficult job but you will need a helper to R & R the haevy lift cover.

'm also looking. Apparently, TSC stores in the USA carry a Ford TransHydraulic fluid that's yellow metal safe. Canadian TSC isn't the same company. I tried a Ford/new Holland tractor dealership and they'd give me a multograde product they claim will "do the job". I can't remember it's name.
