I took my new Max II (less than five hours old) out for ride this afternoon and tried to cross a creak and in the process lost power to the left three wheels. I made a cursory inspection down in the creek bed but could not see anything obviously wrong. It was dark by the time got the Max II back to the house so tomorrow I intend to dig a little deeper to see what is the problem.
Any suggestion on where to focus my search would be appreciated.

New Max II less than 5 hours old. Does this mean it is a 2007 or 2008 or is it used but new to you?
To start:
I'd check to make sure the shift lever is fully engaged in the down position and the control levers are pushed all the way forward. |

Used but new to me. Totally rebuilt including a new engine, tires, bearings, seals, chains, etc. Not sure about the transmission though.
We checked the shift lever in the up and down position but we got the same result. Just the left three wheels spin. Any advice would be appreciated. |

Check the part on the transmission that the shift levers attach to. The should be sort of diamond shaped flat steel. There will be a plate held on by two bolts that hold the "shift group" in place or if it is older there may be snap rings.
Remove the plate and shift linkage rod and pull the shift group piece up out of the transmission. On the bottom side there will be a steel pin about the size of a #2 pencil eraser. If the pin is gone then the shift group piece will just pivot but the transmission is not really shifting on that side. If it is there look down inside the transmission for a shift collar, check it for damage or a broken piece missing from it. If it looks ok use a screw driver and move the collar and see if it engages and you get power to that side. |

Jerry;
Excellent advice! This weekend I am going to try your suggestion and give you some feedback.
Do you recommend that I jack up the vehicle and test it with the tires off the ground or just test it on the ground?
Thanks! |

You don't need to jack it up for this, you can just do a quick check. They get broken like this on the trail sometimes and a person can pull the shift group and slide the collar into gear and contine the ride in forward. |

Jerry;
Your advice was right on. The plate was held on with two bolts just as you described.
I removed the shift group and the steel pin about the size of a #2 pencil eraser was intact. I used a screw driver to move the collar and it engaged and I was able to restore power to that side.
I is good to know that nothing major was wrong but How do I keep that from happening again. |

I'm glad you found the cause of the problem. Make sure the plate is holding the shift group down all the way so the pin engages fully in the shift collar. |

Jerry;
Seems I spoke too soon. The problem is not fixed as I was told. We only can get power to the left side and not to the right side. I removed both shift groups and the little steel pin in intact and in good condition. I looked down into the T-20 can could not anything thing broken. I did notice that the T-20 appears to be low on lubricant. I stuck my finger in the inlet port and my finger came out dry. I am going to fill up the T-20 with Dextron III before I tinker with it further. Could the lack of lubricant be causing the problem? I don't believe the T-20 is completely empty because I can see that the shift collars are wet with lubricant but not submerged. |

Thanks Cato. I am hoping that my problem is not so severe as yours. I guess I need to open up the T-20 and take a look see. |

Cato;
I found what I think is the problem.
I am not sure of the correct name of the broken part but I'll describe its location and maybe someone will educate me. I seem to have power coming out of both sides of the transmission but on the right side the first set of chain and sprockets are turning but the subsequent set of chain and sprockets are not. The number 2 sprocket and the number 3 sprocket are on the same shaft. The number one sprocket is located on the shaft coming out of the transmission. The problem seems to be that no power is getting transmitted to sprocket number 3. With the engine running I can see the first set of chain and sprockets turning but the number 3 sprocket just wobbles.
In an effort to get the number 2 & 3 sprocket assembly out of my Max II I removed the four carriage bolts and for chain adjuster nuts but I am unable to remove the assembly from the general area even though it is complete lose and free. I am reluctant to take more of the Max apart to get this broken assembly out but I don't see any other option. Any and all advice would be helpful.
Does anyone have a number 2 & 3 sprocket assembly for sale that accepts e. mail communication? |

My biggest problem now is how to remove the assembly without doing a major teardown.

It sounds like from your description you are working on the jackshaft. It won't come out just by removing the carriage bolts. You also need to remove the two cotter pins at the ends of the shaft and then slide the shaft toward the inside of the frame through a hole.
You description gives me the thought that the teeth are stripped off the sprocket on the jackshaft that runs down to the center axle sprocket. |

Hi Jerry;
I suspected that the two cotter pins played a role in the disassembly but I thought I could wait until the assembly was out of the Max and on the work bench before I removed them. Thanks!
