Has anyone had experience with removal and inspection of the Pump/Motor Hydraulic Pack? Or, a recommendation for a service facility?

I suspect a problem with my hydro pack in an Arrow IV. Occasionally and intermittently, the gear will not fully raise when commanded. Electrical checks out fine. Motor operates when commanded with or without extension engaged. Appears that the hydraulic pressure is being bypassed within the pump. All other aspects of the hydraulic are fine. Hoof valve is fine. Actuators fine. Pump is full of fluid. No leaks observed. Probability is that a check valve or shuttle valve in the pump is misbehaving.

Anyone disassemble theirs? Are parts available?
