3215 diff lock not working (Popping)

[POC]

Mine is now, after moving some snow yesterday and attempting to use the locker, it acts like the diff is lobed, the pedal goes up and down, up and down....Tractor is a 2007 model, I bought it in 2008, 90 hrs, but the dealer has gone out of business now.
What should I do?
Thanks,
Patrick

Check your owners manual as it may give directions to adjust the diff loc linkage, and if it doesn't let me know and I will try to email you the directions.

See, I said that you were going to be "MY dealer" now.

If he needs a copy of any pages from the service manual let me know and I'll scan them last time I believe you had issues with your scanner.

I appreciate it and I will let you know. I most generally have issues when it comes to computers. It couldn't be me could it. You see I was going to put a smiley face by that and I can't figure out how to do that. Oh Well.

Ok, just got back online....
No, I found nothing in the manual about adjustment of the linkage.
Something would be great.
Thanks,

I don't know if you remember but my NEW 2516 had the same issue. They fixed it and turned out it needed a new piece of metal and some springs replaced. Now it works.

Funny thing is my dealer emailed me saying he had 2 new 2516's come in to the dealership and both of the diff locks on them were not working from the factory. Might be something going on the assembly line?

Well then, let me help you help your dealer get this fixed right. The 3215 is a wonderful tractor.

There are three issues that affect the diff lock prematurely failing. One is the adjustment, some of them just don't engage the cogs fully. The pedal pushes down on a lever and it just doesn't push far enough. A little piece of metal tacked onto the lever takes care of that. Secondly, operator error as some guys apply the diff lock while the wheels are still spinning. That is hard on things. Thirdly, the front axles on these 32/3315's do not pivot as far as they should, so you end up needing the diff lock way too often as when the front axle reaches it's pivot stop it lifts the rear tire and you spin. For years now we have "adjusted" the pivot stop on all the 32/33 16's before they go out and we have seen no diff lock failures on any tractors that we have so modified.

Mahindra is aware and has made Mitsu aware. Your dealer can call Mahindra and talk to the service folks to make sure he fully understands the procedure.

You will note that there really is no adjustment to the pivot stop. The cast block on the front axle is too tall and must be shortened by about 1/4". I won't outline the procedure here since I don't want to feel bad if someone does it wrong and cuts a power-steering hose or messes something up. Talk to your dealer.

I may be wrong, but from the only two posts that he's made since joining this forum, all I see is either someone who has abused the tractor or has made operator errors when engaging either the diff lock or the 4WD.
