My 135 has been heavily modified (see pic in the thread of MF pics) with a commercial FEL and a home built backhoe. When I got it there were lots of leaks in the hoses and the fittings, many of which were just plumbing fittings. After replacing the hoses and putting in proper hydraulic fittings, the external leaks have disappeared. My problem now is that several of the functions do not hold under load. Eg. If I leave the outriggers in the up position they will slowly collapse to the ground over a few hours. Same with the bucket tilt. I would like to fix these problems but don't know how to determine if the problem is in the control levers or the internal seals on the cylinders. Any thoughts are much appreciated.
