Would you post the link as to where to find Mahindra parts diagrams are located?
PS
I finally changed the Royal Purple hydraulic oil on my Kubota L39 after near 1,500 hrs since last change. Oil was a bit dirty as it has wet brakes and wet hydraulic shuttle clutch. If I could super filter the oil, it would be good as new. The particular dual filters on the L39 have strong magnets in the filter bases. There was only a hint of metallic sludge on them. If you are finding metallic items in your suction screen, that is not good. suggest using a better oil.
On my Max 28 I plan on going a long time with the hydraulic oil (800-1,000 hours) before changing after the first 100 hour service. (I'll change filters every 200-400 hours)
