mahindra 8560 loss of power

[jjb2001]

info of tractor. Previous owner tipped on side while loading bales and left tractor idling witch caused catosprohic engine damage, mahindra warrentied the claim and rebuilt the lower end and installed a new short block. Ran great, I bought the tractor with 498 hrs on it. only 30 hrs on new motor, I changed oil in it and noticed some metal in the oil, just figured it was from the rebuild. At 543 hrs while brush hogging it windowed both sides of the block, i sent a rod thru both sides of the block. Mahindra warrentied it and a new motor was installed.

Now since ive got it back it doesn't have the same power that it had before not even close, in road gear i cant climb a little hill without downshifting, while pulling the disk i could disk in m3 before now its L2, just feels alround doggy. I've changed fuel filters and air filters. no change. Anyone with any other advise for me to get the power back.

Yep. Send it back to the dealer who rebuilt it.
Amazing that Mahindra "warrantied the claim" from an engine destroyed while running on its side... Even more amazing that the second engine 'grenaded' and you got a third engine and you're asking us what to do. Get it back to the generous dealer asap imo. Today!

spanner, I had to eat the labor and they ate the parts, as it was a bad batch of piston rods, the numbers machined into the rods were to deep and weakend the rods is what i was told, but i was trying to avoid going to the dealer as i need the tractor and i may have worn out my welcome as the last two times it was there it was there for 6 months apiece and i was a bit heated about that, and the dealer is 300 miles away. but it may require another trip to them. thanks.

Certainly I'd check the compression, and make sure that the cam and the pump were in time. You should be able to do that much yourself.
Assuming you've checked fuel quality (water, fungus, bacterial blooms) and delivery (filters, screens, etc.)
