1983 Zetor 6011 main clutch and servo issiues

Hi everybody. Merry Christmas!!!


I have recently bought a 1983 Zetor 6011 which needs a little TLC and I have some questions and I was hoping to get some input:


1. The main clutch (clutch for the driving gearbox) does not free out completely. Is there an adjustment on this please? If yes, can anyone give me a short descripton as of how to adjust it?


2. I wish to change the servo oil on this tractor. I do have available an aw 32 hydraulic oil or a synthetic ATF oil which covers these specifications:

Automatic: ZF TE ML 03D/04D/09X/11B/14B/17C, Dexron II/IIIG, LT 71141, BMW LT-2,
MAN 339 Typ D & F, MAN Z1/V1 & Z2, VW G 052162, MB 236.10/236.11
Manual: API GL-4 (75W/75W-80 & 80W), MB 235.4/MB 235.5/MB235.10/Volvo 97308

I am a bit reluctant to use the synthetic ATF oil because it is synthetic. It's an old system, and it also have a tendency to leak.

Could someone put me in the right direction on this please?



3. Does anybody know where these tractors usually leak in the servo system please? When parked inside, there is a small pond of oil from around where the power steering tank sits after a while. It would be very nice to rectify the leak before I changed the servo oil.


Kind regards Martin

Is your 6011 got a hydraulic clutch? if so they are automatic adjustment. When your talking about changing the servo oil, where are you talking about? as the oil for the hydraulic clutch is brake fluid. 32 hydraulic oil is for hedge cutter heads and the like.
The power steering tank is in front of the radiator. the hydraulic clutch system can leak at the master cylinder or slave cylinder each which may need changing every year or two.
