Max II ?

[CROSSBOW]

Does all the Max II s make popping noise even when your going straight. I replaced all the chain and adjusted it with the tires off the ground.It sounds like a bull doser running on tracks. The left chain adjuster looks as if it sticks out to far, the bottom chain almost rubs it.The right side has good clearance. If i slide the sprockets over the chain would rub the tub. This is my first 6x6 and was wondering if they run quiet or if they made alot of noise.The bearings have a little play mabe 1/8". Thanks for your help guys.

My guess is a bearing is going out. Dousnt take much play to put a chain out of alignment then it will pop. If u don't fix it now next u will changing sprockets and chains.

Chain stretched or the sprockets are worn.
Maybe the chains are too tight.

Do all the sprockets line up? I had an old max once where the frame was tweaked and the sprockets on the jack shaft were out of alignment bad.

My friend's Max IV made a clicking and popping noise when his bearings were going bad.

[CROSSBOW]

It is clicking.I don`t think the chains are bad they aren`t but two weeks old. The adjuster is near the top.When i first bought it i took it to the only guy in town to fix 1 bearing when i got it back and 600.00 less he didn`t tighten the 4 bolts on the jack shaft,left the colar locks 3/8" away from the bearings and both chains on the left side popped off when i backed it off the trailor. My guess is the center sprocket might be out of line. I think i`ll try to replace the rest of the bearings myself. Thanks guys for for your help i hate to sell it i enjoy driving it but my 4 wheeler was less trouble. When it`s in the water it sounds ok.

Were the old chains stretched?
If yes than the pitch on the sprocket could be also.
New chain on worn sprockets will pop
The sides of the teeth will show signs of wear from the chain and the teeth will wear to a point then the point will break off.
Compare your sprocket to a new one and you can tell if they are worn.

$600 is outrageous! I'd say it's even a bit heavy for doing all 6 bearings. Bearings cost as little as $13 each to as much as $45 for the real good ones. Also assuming about an hour labor per bearing @ $60/hr shop time. Why did he even touch the jackshaft? Did HE replace the chains too? Jackshafts must be alligned properly or it could be causing your problem. First level and square your jackshaft, then tighten the nuts in even increments....what you do to one side you must do to the other to keep the shaft level and square.

No he just replaced the bearing on the outside. I bought the chains after getting it home. I cut the long chain 5'3 1/2" s long. After replacing the chain i did like the vid. on this site that Mike done. When its jacked up off the ground it runs fine ,hardly any noise. The guy that worked on it was the only one around here that was listed that worked on Max atvs. Took him 2 weeks. I don`t think he had ever seen a Max before, i know he didn`t know what a colar locks purpose was he left them loose on the axle. Why does it run fine when its off the ground? Thanks.

Try and back off the chain adjusters a bit and see if that helps

You have a bad bearing. Try replacing it yourself this time. If you had one that was bad....it is very likely the rest are not far behind it, you might as well replace them too.
Try buffalo bearings Buffalo Bearings Inc. They have inexpensive ones from about $13 each.

When your tires are off the ground it takes the load off the bearings.
BTW the lock collar on the outer bearings is what holds your axle in place....and your sprockets in allignment. I like to put a spacer between the sprocket tube and the outer bearing to hold everything in place (just in case).

Bearing failure is usually caused by a failed seal or lack of grease. if you think a bearing is bad replace it and grease the ones that seem ok. Don't over grease them or you could blow the seal...2 pumps and you should see some grease come out around the seal...if not it might need a couple more.

[swamp donkey]

This may just be my opinion but I try to jack my max up and have the axles spinning just a bit when I pump the grease into the bearings seems to make the outer bearings last longer but that's just my thought.

[CROSSBOW]

Thanks guys , I pulled the tires off the left side and placed a straight edge across the out side of the axle and the middle axle was sticking out a 1/2" past the other two axle. I moved it back in line and it helped alot with the popping. Now if i can stop the chain adjusters from popping up when i turn it should be ok. thanks again.

The chain adjusters will get worn and start to slip on you but RI has them and there not to expensive. My cousin made some for his max like the guys here at 6x6 world did and they work great that's probably what I'll do when mine start slipping.
