SNAP, CRACK, RIGHT SIDE will not move.

[wheeler]

Max 4
2002 model
I had just got done pulling something with the 6. After I unhooked the 6 from the thing I was pulling and started to pull away, I heard a Crack then the right side froze. Can not move the wheeler as it is froze and the right side will not move. The left side moves fine. But the chain is as tight as it can get on the right side. It's now 200 yards from my garage and I have no way of moving it. IDEAS will be much appreciated.
Thanks

I'd start with taking the chain off the T-20 on the right side and see if it's the transmission that's locked up, or if something is lodged in the chains. If it's the T-20 that's locked up, taking the drive chain off will at least let you tow the machine back to the garage. If the drive chain is so tight that you can't get the master link off, just cut the chain.

Good luck; let us know what happens.

Yes

I'm glad you brought that up. I completely forgot about taking the chain off to move it. I have been so busy this summer I have not had a chance to visit this site. Mike is there any movement with the Max corp. over across the pond. I'm not even sure if I need to get a new tranny where I can find one at. OR where can a guy get one repaired nowadays. Any ideas there?

Try this video. It shows how to repair the T20, step by step. I used it to repair mine, having never done it before.
This guy's name is Brandon, he repairs these transmissions, too. PM him, "MaxRules99" I think is his alias here, see what he says.

A tool that dropped in the tub and got caught in the chains will do exactly as you describe.
Also the @#@$$ seat-belts do the same!

[wheeler]

Yes, great ideas!

My guess is perhaps chain was just loose at onset and has doubled over either at frame or tensioner. If that is the case engine tower may need removal to get to it.
Good luck and let us know what you find.

I had a similar problem this week with my MAX II...the master connecting link on left side vertical jack shaft chain lost the clip, and the link fell out causing the chain to drop and become tangled in the chains, locking the left side. Long story short, I found that this machine is bear to work on, but several hours later, I finally got my pudgy arm down there, got the chain loose and was able to replace the link.

Well found the problem. The rear small drive chain under the engine platform has broken and folded over and lodged under the sprocket. I can't get the chain out with my mitts. Its wedged pretty tight. I cant move the machine yet, so i can't lift the engine and engine platform out. So onto figuring how I'm gonna do this?

[Rusty-Gunn]

My M-IV broke the right side primary chain and it locked up as yours did, but my nephew was able to get that chain out.
The thought I had at the time was to shove a 2x4 under the axle/floor (tub) to flex the bottom downward, thus giving more room to get the chain out. We never did it, but just maybe it might be worth a try?

[wheeler]

Anything is worth a try. I'm sort of lucky as the machine JUST made it out of the woods which makes it a little easier to work on.

In the field repairs on max4 I pull the rear seat and walk the engine and mount forward. Have don it by my self and dosent require much lifting at all.

And then leave the extremely tight back seat out and put plywood down so you can haul stuff.

Well got the jammed chain out. It was quite a surgical effort. I had to take a winch strap then attach a heavy duty piece of wire on the chain to the winch. I winched and got it to move a little. Took off the sprocket and then lifted the machine both front and back. Then spun the wheels until the chain came out. Now I need to get a link for the chain. I'm also looking for those black plugs that go in the chassis to keep water out. I've ordered them before but now can't remember where. What size are they for the MaxIV. 3/4 inch?

[Rusty-Gunn]

Plugs are 3/4" size.
