Massey Ferguson 6180 clutch issue

[MF H]

Hi All,
Looking for some help regarding a clutch issue on my MF 6180.
The tractor is slow to react when operating clutch pedal. I have carried out a pressure test on the low pressure side at the clutch valve test point and have a good 17bar. When the clutch pedal is down it drops to 0 but takes a good couple of seconds to drop completely to 0 bar and provide a smooth gear change. If you do not wait long enough it is hard to get into gear. The main issue is when you have moved and you operate the clutch pedal the tractor takes too long to stop moving.
Other info:
Tractor is a Manual shuttle
Lift, pto, steering, 4 wheel drive and diff lock, dyna shift function ok
I have not tested the trailer brake system.

Any advice would be appreciated.

Try bleeding the clutch valve to see if it makes any difference

@MF H did you ever find a fix for this fault? My 6180 does the exact same thing.

Sorry for long time silence. Not been using the tractor much and with it being manageable at the time and lack of time to get to it never needed to delve too deep. I am now in a position to get back to it and I would say it has got a little worse.

Tried bleeding the clutch no air and no difference.

Carried out some more testing recently. 17bar test point on clutch valve is now around 13-14bar when clutch pressed drops to 0. Still takes considerable time to engage gear.

Other testing:
Testing at clutch valve test point again. Clutch peddle depressed and 13-14 bar. Pressure dips when operating pto and diff lock before coming back up. If you Rev tractor more pressure rises close to 16-17bar. With the tractor off any gear can be selected easily and if you start in gear no issues.

Any suggestions will be appreciated.

Thanks
