Hello everyone,
I am having trouble with my 1998 Max IV tranny. After reading some I see that there is a lot of knowledge here and I need some. I just bought this machine and I knew it had problems but I wanted one and I am willing to put in the wrench time.
When I put it in reverse and pull back on the right handle nothing moves. The left handle makes the left side spin but the right does nothing. I checked and the sticks seem to move back about the same distance. Everything works fine in forward. I am wondering if it is the same band on the right side for forward and reverse or are there different ones. I am pretty sure the bands need adjusted. But if it works in forward would being far out of adjustment really cause that one side to do nothing? I couldn't get to the top of the slide rails to measure them but the bottom rails on both sides are almost an inch from the tranny housing. That is with the springs still connected and I didn't pry them out. I read that they should have about 5/16" of travel when the springs are removed and they are pried out with a screw driver since I don't have the adjustment tool. I also saw how the linkage for forward/reverse went to both sides of the tranny I wonder if it is possible that the left side is moving to reverse but the right side isn't getting all of the way back into reverse. The linkages don't look bent in any way. When I pull back on the right side it almost sounds like it is still in nuetral it doesn't squeel the engine just revs and nothing. I also checked the fluid level which is ok. I am going to take the engine off today along with the platform it sets on so I can get to the tranny and try to adjust the bands. Any help would be appreciated. I have never had one of these apart so I am nervous to tear the tranny apart and not be able to get it back together. I can usually put anything back together I am just worried when I pull it apart gears will fall out and I will not know where they go. Are there any shops in S.C. that work on these? Also does anyone know the setting for the fuel mixture screw on the side of the carb? mine is running too rich and when I leaned it out the motor would bog down on hills and the wheels wouldn't spin it just stopped and I had to roll back down. Even with the motor at full throttle when I got half way up a steep hill it would bog down and stop.
I am also curious I thought the smallest motor they put on these was a 18hp vanguard but mine has a 16hp, also the metal plate riveted to the front has Max II on it but it is a four seater and doesn't look modified. Thanks again for the help.

I'm kidding, even that is much more simple when the T20 is out of the 6x6. It really is a simple rebuild. The rebuild kit include seals, orings, washers, etc and it is very cheap. I think it was around $50. You can buy it direct from the manufacturer
