Buck at EFCConstruction used to sell them, and if i remember right he said he quit because of quality issues. You can e mail him and ask him about it. He is a straight up guy and will tell you all about them. If you talk to him tell him to stop by here. I believe he has in the past.

Clutch Free Peddle Adjustment:
1. The clutch peddle should have about ½” free play as you push it down before you feel any resistance of the clutch spring.
If it is much tighter than ½” there is a possibility of burning the throw out bearing out. This is like the problem of riding the clutch in an automobile.

Adjusting the clutch free play is about all you can do to stop grinding gears. After that it is probably time for a clutch replacement.

There are two types of clutch used on Mahindra/TYM Tractors.

Single Stage Clutch:
The single stage clutch is less expensive to repair due to less number of parts.
When you push the peddle down it should feel the same all the way down with no notch in the travel

1 Clutch out of adjustment - No free play
Refer to service manual for proper adjustment procedure of clutch, any associated hydraulic valves, and transmission brake, (if equipped). Clutch disc may be burnt due to improper adjustment. (Any clutch slippage, even for a short time, can ruin clutch).

2 Slipping and Chattering
Driver resting foot on the clutch pedal. Don't use clutch pedal to rest foot on. Adjust clutch. Release bearing may be failing. Clutch disc may be burnt at this point. (Any clutch slippage, even for a short time, can ruin clutch).

3 Clutch Slipping - Oil on clutch
Transmission or rear engine seals leaking. Replace clutch, bearings, and all seals in clutch housing. Grind or replace flywheel.

4 Clutch Slipping and hard to get or out of gear
Overheating due to excessive clutch slippage, disc warped. Replace pilot & release bearings, clutch disc, and pressure plate. Grind or replace flywheel. Always check transmission and rear engine seals.

5 Clutch has been engaged with engine RPM too high or too high of gear selected
Replace clutch, bearings, seals, grind or replace flywheel, and educate driver.

Synchro-Shift. Essentially a collar shift transmission, with the addition of synchronizers, which allow for crash-less shifting on the go. In order to achieve a smooth shift, the first thing that must happen is an "equalization" of rotational speed of the gears that you wish to bring into mesh with each other. This is the chief function of the synchronizer. Let's suppose our transmission is synchronized between 3rd and 4th gears. We'll start out in 3rd gear, and then shift into 4th. As we shift, the first occurrence in the chain of events is that we move the transmission out of 3rd gear, and into neutral. As we continue moving the shift lever towards 4th gear, a brass cone applies friction to 4th gear, increasing or decreasing it's speed to match that of the rotating collar. Once the speeds have equalized, the gears still may not be lined up with each other, so there are little triangular shaped teeth around the outer circumference of the brass cone, which serve to ever so slightly rotate the shift collar teeth, and the gear teeth into perfect alignment. This whole process occurs rapidly, usually allowing a straight-through shift, directly out of one gear and into the next. Synchro transmissions range from simple, where only a single pair of gears are synchronized, on up to full" synchronization of all speeds, including forward and reverse. Shuttle-Shift, which refers to synchronization between forward and reverse, is a real benefit to have on a tractor that will be used for front loader work. Still a reliable transmission, but a little more subject to failures because of the extra bearings, synchro rings, etc. that are in use. More complex = more potential for failures to occur.
