hello

when i check the clutch linkage to the clutch piston i noticed that the piston doesent come all the way down in the shift-control valvehouse.

so i disconected the linkage and noticed that the piston is pushed upwards by a spring of some kind in the bottom.

but when i pull the powershift to third gear its pressed down to the bottom by the powershift linkage.

should the clutch-piston be in the bottom of the valvehouse always when the clutch is reliesed or should it be about 2cm up in reverse + 1st + 2nd gear and be pushed down in 3rd gear?

if it should be pressed down what does the spring in the bottom do?

the reason why i´m asking is becaus the tractor slips a little och the clutch in rew+1+2 gears but never in 3rd gear

and if i pull the clutchpedal upwards it stops slipping
but when the clutch is pulled up the piston in the other end of the linkage is down as far as it goes

i also noticed that there is al little freeplay in the linkage on the left side of the floormount that could affect the piston to glide up when it shouldent.

Thanks for help C-J

HELLO

The spring is in place and works but the last cm it dosent

have the force to pull it up.

but there is a little freeplay in the linkage so maybe that wats causing the trouble

i will mount a new pin in the linkage this weekend.

and see whats happen.

thanks for all your answers C-J

As cshess said previousl, I'd check the spring on the pedal. The return spring must be the proper one.

as Rod said first thing make sure that spring at top of clutch pedal nder dash is correct an that should pull pedal back against stop under there.If you have to pull back with foot that is not necessary an you should not use till corrected.

If there is an upper limit stop bolt I would remove it. Early in the 70 series I did many and that bolt can keep the pedal from coming far enough to seat the clutch spool, it makes adjusting a whole bunch easier if you let the clutch spool do the pedal stopping.
I'd be surprised if it has an upper stop bolt.

yeaah thats a real powermachine

Thank you

this was all i needed.

not many shops knows anything about this tractors in sweden.

Thanks again C-J

But I be they've a handle on 2 cycle Saabs..........

When the clutch pedal is completely released(up) the spool in the valve should be pushed in the valve as far down as it will go. There is a spring and poppet in the bottom of the spool that hold trans pressure. That is why the clutch does not slip when you pull up on the pedal because then the poppet is held firmly in place. Those tractors use a very stiff clutch spring to pull the pedal up all the way. It is possible that your tractor has the wrong spring installed and not strong enough. Do what needs to be done to get that spool all the way down when the clutch pedal is up, a new clutch spring might be all you need, Rod.
