Oil leaks on differential

It was true that GL-1 was available from the Wal-marts here in the US, however, their supplier, Quaker state discontinued production of that product earlier this year. GL-5 and R&O oil are the only Hydrolic oils available there now. And neither is 1st choice for this system. R&O is NOT recommended.

I recommend the use of straight 90 wt. Minerial Oil (i.e. GL-1 rating) 90 wt summer 80 wt winter, though I have not seen 80 wt.

The GL-1 oil is available from several sources...

Massey Ferguson Dealers PN MF-1103 and goes for ~$37US / 5 gallon
Shell DENTAX GL1 oil- available from a shell oil distributer (see local phone book) also goes for ~ $36US / 5 gallon.
Another source is NAPA auto parts stores. PN 65-205 goes for ~$27 / 5 gallon this is a special order item from the whare house and takes a day or two to get it. (at least here in Cincinnati)

Lastly if you are near Latham Ohio you can get GL1 oil from the Latham auto parts store for $17.99 / 5 gallon.

You can also get the FORD Transmission oil from TSC though this is reporttedly a GL-3 oil.

Just don't waste your time at the surburban auto stroes like PEP-boys, AutoZone, etc. They don't know squat about tractors and look at you funny when you finally admit what your looking for.

Theses systems require a balanced oil to do the two jobs.

You may not be in immediate danger of doing damage to the transmission but I would suggest you revisit the parts shop, and research this site to verify that you do or do not need to change the fluid out. Check out the link on oils by llamas.

• LLAMAS oil article.

Couple of questions first.
Are you going to change out the trandmission oil or reuse it?
Does the oil have water in it?
Where are you located? US, UK, Austrailia, etc...
Do you have any problems with the hydrolics... i.e. leak down etc.

These questions will help to determine where to direct you. And also while you have the backend drained it is a good time to fix a lot of thoes little problems.

1st: To replace the PTO oil seal. All you do is drain the system, then remove the 4 nuts around the PTO. This allows the retaining plate to be removed. Then the PTO it pulled out. It can take a little effort. If it is big effort some twisting in the PTO could have occured. Check back if that is the case.

Once out the PTO seal retainer should just slip off. Remove the "O" ring and drive the inner seal out. Get a new seal ~$13US from a full line Massey Dealer & $1US for the "O"ring.

The new seal is put in then drive it flush with a piece of wood. The seat it in the retainer. I used a PVC coupler and a vice. The PVC coupler was thick enough to catch the edge of the seal.

For the axel seal I have heard of a product called sure seal. Search the archives, here and on the N board. The process has been described a few times.

Mineral oil in Petrolium oil as opposed to vegitable oils etc. What you want is 90 wt. GL-1 Gear Lube. This is sold under many brands.

Massy number is 1103 and is ~$38US/5 gallon
Shell Oil produces "Dentax" at ~$36US/5 gallons
NAPA sells it for ~$26 /5 gallon Part Number ????
I have to get back with that.

If in the US look in the phone book for oil distributers... They will have or can get the Shell brand stuff. You are right Auto parts chain stores are helpless here. Particularly PEPBoys Just terrible.

There is a water clean-out peocedure if needed.
