Ha ha ha! It does have chains on chains on chains. But the chains on this one are well oiled. I’m not anticipating any issues with that yet. But I do plan to find out the size of each chain and stock spares.

My credo
Its probably better to be self deprecating than self defecating.
Duramax... before you can be strokin or cummin you need to be hard as a rock.

Don't discount it just because it is a single cylinder, some of the industrial singles are up around 20hp...

You can't put that much power through 734 feet of chains!!!
You can do almost anything once. Whether it survives or not is another story...

So I did a little research and there was a guy on U toob that went over how he does his trouble shooting. He recommends disconnecting all the kill wires to eliminate the possibility that it’s a bad switch or grounded out wire. So, I’ll be trying that when I get the time next week.

So I forgot to update. I got her running! The points were rusted shut and the coil was rusted to hell. I went ahead and put a new carb on it too. It’s a lot of fun but lacks power. I just found a 18.5hp 3cyl Kubota diesel engine at a local shop for less than it would be to get a new honda engine for it. Plus the charging system will work out fantastic with the alternator, I’ll be able to put together a heater for those cold days and fuel mileage shoul be significantly better!
There will be a little fabrication involved to get it to work though. I plan to do that swap over the summer.

Finished the dog box yesterday. Haven’t started building the tracks yet. I need to go buy some more metal before I can.

Started building the snow tracks. The aluminum cost me way too much. But I think it should work. When I get home I’ll start making the backing plates and hopefully get some of the guides installed. After I get them all installed I’ll have to build a couple hinges to tie the tracks together.

I had a max ii in the day. (Around 2013). Mine had the vanguard V twin.

Best thing you wanna do is get the bearing cages for the front axles, also with that kubota engine i wouldnt expect it to float very well, and i would also plan on rounding off alot of chain sprockets. The T20 trans is a pretty stout piece however.

A guy i rode with had one with a 40hp kohler in it. Thing was insanely fast. My 16hp briggs only did like 20-25 but you would be surprised the torque a lawn mower engine makes. It would climb anything.

That’s awesome! The front axles are the ones that have bearing issues? I looked around but couldn’t find bearing cages. Do you have pictures of them? Maybe I can build some. I really haven’t drove it much and plan to mainly use it as a snow cat for hunting.
The kubota weighs 50lbs more than a 20 hp briggs but should get better fuel mileage. I haven’t torn it down yet so that’s a long term goal. Right now it still has a 15hp singly cylinder briggs which is fairly under powered. It’ll go 10-15 mph I think.

Thats not the stock engine then. They only came with 2 stroke snowmobile engines untill like 93 when they switched to the 4 stroke twins. The snowmobile engined ones were fast (35-40mph) but the 4 stroke twins were much better for trail riding.

The bearing cages are basically a bracket that bolts to the tub and the axle rides in them. Otherwise the front axles bend very easy.

I cant find a picture. But its actually more of an axle cage then bearing cage.

Try www.6x6world.com if the site isnt totally dead. Those guys live and breathe these things.

RI (recreative industries) the ones that built the max got bought out in 2017 by mudd-ox. Somethin happend there and someone else bought the max brand to revive it but last i knew they hadnt yet.

So parts are hard to get espicially things like the cages. Custom or used is the only real option, last i knew. I kinda quit following these when i sold mine.
