Gear retraction issue

[pilotpat]

One thing we came across was a sticking pressure switch plunger: the plunger sits on top of the hydraulic pack and moves up and down by the system pressure to actuate a microswitch, which turns the pump off/on. The plunger was intermittently sticking (so pump may not start and gear may not continue moving after the accumulator pressure bleeds off) until fixed by a new o-ring kit, no problems since.
Good luck!
