4340 Clutch will not disengage?

[collincordell]

Hello All,

I just aquired a Zetor 4340 and thank God for this site as I have learned so much. This tractor is old but seems to work wonderfully except that I cant disengage the clutch. I found that the slave cylinder was shot so I replaced that but no luck. I inspected the Master and it shows no visable signs of leak.

I can run the tractor at a very low idle and force it into 1st gear only If I try to put it into any other gear it just grinds like crazy. I can put the tractor into high range 1st gear and crank the tractor in gear and cut my big pastures but I have to kill the engine to stop.

Any ideas? I checked out the master clyinder which I assume is the one right behind the clutch panel and I didnt see any place to bleed it, but I have bled the slave till the cows come home.

Please Help
Collin

Hi Collin

Do you have much pressure on the clutch pedal when you press it down ? In other words is it moving the slave cyl ? If it's okay then you probably have a broken buttress cap. This can be replaced through the inspection cover on the l/h side of the bell housing. You should be able to find how to do it on another post on the forum.

Yes there is plenty of clutch pressure and the fork is moving properly. I will check the threads on the buttress cap.

Thanks alot
