Zetor 3340 with air in the clutch

[llazyllama]

I have a Zetor 3340 that is getting air in the clutch. I can bleed it off and it gets air back in it within an hour or two. I can not see any fluid leaking externally. Not sure how to figure out if it is the Slave cylinder or the Master cylinder. Any advise would be appreciated.

95% of the cases, its the master cylinder. Dismount the dashboard sheet, bolt out the pedal/cylinder assembly and pull it towards you and check for oil sweating out on the open end of the cylinders.

Thanks, I pulled the clutch master cylinder and found a tiny leak on it. Ordered new one through Ridgeway Enterprises, It came Friday and put it on Saturday. Tractor is back to new. Thanks for your help .
