15 / 16 series block cracks

We are talking about the cracked block on the 3316, owned by jwcinpk. He didn't mention how he discovered the crack. See post #1.

See post #10-11.

My crack was substantial and obvious. There was oil gushing from the engine like a lung shot deer.

I'm pretty sure it would be quite obvious when a block is cracked, i.e. fluids leaking all over. One thing that should ease your mind; the 3215 has a loader bracket unlike the 2615. My dealer had a 2615 with a cracked block, come in for repairs. The owner had never even done the 50 hour service, or check anything on the tractor. He just ran it until it broke - total abuse. It cost him $4000 to fix it, and he loves the tractor because he knows he neglected it.

How many hours did they run without servicing?

jwcinpk, the guy ran the poor tractor for over 3 years without doing any maintenance.

I had the bolts on my 2615 Loader loosen up before Mahindra did the big Service Notice.

I cleaned the bolts and the holes and used some Red Loctite. 200+ hours later they are still tight. (Knock on wood). Loctite - it does a loader good.

The bolts should not loosen if the system is appropriately designed and the bolts are torqued to spec. The full torque is very important to keep the joints stable. Possible problems can arise and remain hidden with Loctite if the bolts are not torqued to spec. The bolts dont back out, but the joints move some and clamping pressure is reduced. I really like the product, but I feel safer seeing a system stay tight without Loctite.

I'm pretty sure the Service Bulletin that came out after I had done it specified using Loctite. I'm not an engineer but have worked with many and from what I can tell Loctite is a very useful tool in situations where vibration is likely to occur.

I continuosly had trouble with the wheels on my 7010 coming loose. I had a little bit of everything happening from wheels cracking to studs breaking. In the end we added a collar to the wheel and loctite. So far so good.
I agree the subframe should stay tight on it's own, but I think when mine goes back together it will have loctite on it. Loctite isn't a substitute for maintanence checks but I think I'll take a slightly loose bolt over really loose or missing bolts.
Just remember to check them periodically still!
