@001 MAX IV with Rubber tracks

[Hogneck]

WHY WHY WHY WHY?!!??!!
My max with factory rubber tracks and track kit w/5'' extenders.Solid axels with support channel connecting all 3 wheels. Tracks have cut an immense groove through the rear of tub on both sides !!! All axel bearings are good no movement in axels at all There is at least 3 1/2'' between tub and track. The only thing comes to mind is when torquing a hard turn the the tires give on the side walls enough to bring the track to close to tub All tires are at 4 1/2 #'s of air and holding on rim just fine. If this is the way it is going to be......anyone want a Max??? Only riding I have been doing is a little plowing around the yard !
Next question .......can the tub be welded back together and how?

Sorry to hear about your troubles. I can't say what happened but it can be welded using a plastic welder Nd some abs welding rod. It sucks to have to fix it but at least its fixable.

I got my plastic welder off Ebay. Urethane Supply Co Model 5600HT Mini-Weld Model 6 Airless Plastic Welder (0694687001445) | eBay They are easy to use, just make sure you have the correct welding rod, HDPE. The kit comes with only a LDPE rod. HDPE welding rod can be gotten from US Plastics Corp 1/8" HDPE Oval Welding Rod | U.S. Plastic Corp. One pound of welding rod will last a long time. Just make sure that the unit is turned off before plugging and unplugging it or it will burn out.

Hey Hogneck,

Some pictures of the damage to your machine would go a long way to determine the proper way to fix it. Since your Max IV tub is polyethylene, a good start would be to get some scrap HDPE from one source or another, and try to weld the holes/cracks back together with some thing welding rod you make out of the scraps. Let's see the damage first, before we get too far.

We can save it.... I promise.

How do I drop pictures onto a thread?

THE CUT IS ALL THE WAY THROUGH TUB ON LEFT AND RIGHT SIDE

THERE SEAMS TO BE ENOUGH ROOM TO RUN TRACKS.

Man, that's tough....

The only thing I can surmise, is that you're getting a lot (a LOT) of flex out of the side walls on your tires, and that's letting the tracks slide over toward, and grind into the tub when you're either turning, or when one side of each track is on an incline. I've seen something similar on Adair tracks when one side of the track is tweaked over toward the tub. I don't think it rubbed the tub, but it came darn close.

What tires are you running, and at what psi? Outside of repairing at this point, let's figure out how to alleviate the problem. Is a couple-more psi an option, in order to stiffen up the sidewalls? I think that welding up the tub with some home-grown poly rod is an option. If you struggle to find any black poly, I have a butt-load of black poly from an old black Max IV tub I can mail you.

Mike , can I use oxy acetelyne torch with small tip to weld with. Kind of like brazing? I have hdep plastic

Just to help clarify what you want to use, I meant hdpe when I said abs in me first post. Abs will not work and I bloom me errar un to a rapid response and lack of prooph reeding abilities on y part.

After looking at the pics. It seems to me that it looks like a left turn caused the rear of the track to come off and rub without being noticed. It probably wasnt all that long, just until the right turn pushed it back on. Because it fell to the inside it didn't come completely off thus allowing it to correct itself after a little damage. I would suggest more psi, different tires, or making sure you ot someone watching your rear. Btw were you doing doughnuts with your tracks on?

I would get someone to drive it like you were and you should stand outside and watch what's going on best way to diagnose

Plowing with alot of ice under foot while turning at the same time........maybe?
