Re: 300 Utility Clutch with TA Problem in reply to Joe Kimbriel, 03-15-2009 08:52:53 On a mechanical TA there are three adjustments you need to get correct.
1) free travel on the engine clutch
2) free travel on the TA clutch
3) the TA clutch shaft must move as soon as either the engine clutch pedal or the TA clutch lever is moved
To adjust the linkage start by disconnecting the main clutch linkage pin at the clutch shaft. Remove the interconnecting link and spring between the engine clutch shaft and TA clutch shaft.
Adjust the TA clutch linkage so that with the lever ahead and the pin in the slotted hole, the pin will move 3/16 on an inch between the front of the slot and the point where the release bearing contacts the levers on the clutch pressure plate. Hold the pin to the rear to compensate for worn pin and hole when making this measurement. That takes care of the first adjustment.
The next step is to set the engine clutch free travel. Hold the bottom of the clutch to the rear and adjust until you have an inch of free travel on the pedal. Holding the lever to the rear will compensate for worn pin and hole.
The last step is to connect the spring between the engine clutch shaft and the TA clutch shaft. Adjust the connecting link as short as possible without moving either shaft while inserting the pins.
Check the adjustment by watching the TA clutch shaft as you move either the engine clutch pedal or the TA lever. The TA clutch shaft should move as soon as either lever is moved.
Dynamic testing can be done by driving the front of the tractor up hill. With the TA ahead and the tractor in a forward gear, the engine clutch should should release about have way down. About 3/4 of the way down the TA clutch should release and the tractor begin to roll backward. This will ensure that the TA clutch engages before the engine clutch. If it does not engage first you will get a double shift when you release the clutch.
