Are you referring to the power steering cylinder?
If so, just take it off and bring it to a Mahindra dealer and let them re-pack it. That's what I had to do with my '97 Mahindra 485 DI. It wasn't difficult or expensive from what I remember.
You may also wanna try a local hydraulic cylinder repair shop to see what they can do. There are parts Mahindra parts breakdown diagrams on the internet where you can find part numbers on whatever you may need. But if it were me I'd just take the cylinder to a Mahindra dealer and be done with it.
I no longer own that Mahindra beast anymore but the dealer I bought it from was super. Been selling Mahindras since they came in the U.S. Very knowledgeable about them. Let me know if you want their information. Also, from what I've read there seems to be 2 or 3 good Mahindra dealers that participate here on TBN.
I'm hoping it's the power steering cylinder you're talking about and not something more serious. Good luck and keep us posted!
