Drive Leg losing trim

[robyonfrome]

The leg trim is droping down to minus, the hydriodic tank is half full so I don’t think its that, any ideas,

one of the trim legs rams is loosing its pressure, look for possible leaks around all hoses..
May also be the damper ring seal inside the ram, try replaceing all the hydralic fluid with new.

There's been lots on this topic over the last 18 months - have a look in the search option.
We had the same problem and it turned out to be a scored ram piston. Took it to a back-street sweat shop in the Black Country for welding and polishing, thereby saving lots.

Getting the rams off is a sod of a job - our local V agent didn't really want to do it due to previous experiences. Our "cure" meant we didn't have to do this.

Leg still drops even now but only very slowly so we can live with it. It used to drop even when not under load but this is not so anymore.

Good Luck
