Mahindra 50 hour service and rear end squeal

[TWinton]

Hello forgive me it this is already addressed in another link, my search found nothing.
1.Which hydraulic fluid is best for a Mahindra 2638, the manual calls for 80W/90 oil which can not be correct.
2. After using it yesterday to move gravel and dirt I was returning home and a loud squeal started as I was driving home.
3. Are there any good videos on how to accomplish the 50 hour service?
4. Can I purchase the service/repair manuals.

thanks for the help in advance.

Search engine on here, is not real good IMO.

There is a You Tube video on the 50 hour service, of changing all the fluids and filters. It's not too bad. The main thing is to be sure to find all the drain plugs and grease zerks. I think the grease zerk locations are marked in the owners manual. They were on my 2538 (early version of 2638, and same drive train).

A word of warning as you get started to change fluids. Mahindra seats all of the drain plugs at something north of 1000 psi on their air guns at the factory. Then they paint them shut for extra aggravation on our part. The first fluid change I did took me 2-3 hours, and most of that was trying to loosen the frigging drain plugs. I had to use a torch to heat up the front axle drain plugs before they would come loose with a long breaker bar.

Another TBN poster was kind enough to post a link to the service manual. I don't remember the link, but if you private message me with your email address, I think I can send it to you. (it's a big pdf file, like 16 meg)

As far as hydraulic fluid goes, I use Tractor Supply premium in rear and front reservoirs/axles. No problem over the 1500+ hours I have on it. 1 more warning, there is ~8 gallon of fluid in the rear reservoir. And once you start draining it, it's tough to stop it, so have a LARGE catch container, or have a 2nd one handy so you can switch it easily.
