case 300 clutch problem

need help if anyone can tell me why my case 300 with a hand clutch and foot clutch will not move i tried to ajust the foot clutch no help put new clutch in no help is there somthing more to this ie. (hand clutch ajustment..filter,,or what )

there is a adjustment on the hand clutch, here is the procedure for the PTO clutch on the 400B tractor which is basicly the same as the hand clutch on your 300, to gain acces to the unit you will have to remove the top cover where the dual or triple range gear shifter is, if your tractor is just a four speed it is the cover in front of the trans 4sp cover, keep in mind there are two adjusting pins one locked and one unlocked at all times, it is easy to tell which is locked by looking at both, then follow the pto adjusing proceure, I have put the trans in gear to keep the rear shaft held while doing the adjustment ( like they say in the pto adjustment but theyare holding/turning the pto shaft) hope this makes sence to you cnt

Sounds like your hand clutch is bad, or out of adjustment. Pull the triple range cover off and take a look at it. Pull the coil wire and jog it over to see what is turning and what isn't in the hand clutch pack. The hand lever should lock upward with a brisk snap, as it goes over center on the collar and fork linkage.

Check the over center engagement pull with a scale similar to the one in the pix. With scale hooked right under shifter knob maximum pull should be 45 to 60 lbs.

To adjust the clutch pack disengage the lever and lift the triple range cover. You need not drain the oil but might help to drain it down some for better view on your first one.

Look at pixs for orientation. You will be turning the input gear (below the reflection in the pix) while holding the drum stationary to adjust the discs.

#2 pix is the complete clutch pack, note the spring loaded lock pins that I have labeled #1 (engaged) & #2. One of those pins will be engaged in a slot to marry the input gear to the clutch discs when the hand lever is in the disengaged position. You will not need a tool for leverage.

To adjust, from the left side of the tractor, with the hand lever disengaged, turn the drum & input gear so you can locate & pull out the pin that is engaged and hold it out with your left hand, turn the input gear with your right hand (CCW increase tension, CW decrease). The input gear will rotate about 10° and the other pin will drop into a slot that will again marry the drum & input gear. Continue releasing the pin that is locking and turning the input gear to get the correct tension. Check the over center pull tension each evolution, the tension change is not linear.

nice pics Joe!! and instuctions cnt

Hey guys, I'm trying to adjust my hand clutch after replacing the discs. I'm not getting throw over, I may have it too tight. Do I adjust with the four speed in gear?
