Hey everyone,
I have a Genie RT 2668 - hours somewhere in the 3500 range. Since owning it, the only issue I had was when a wire frayed between the upper and lower controls. However, between uses (about a week in between), it suddenly no longer lifts, or will lift very, very slowly if the controls from the ground are used.
I threw a gauge on the test ports on the valve block and got readings of 1,000 - 1,600 psi while trying to lift. I did not yet chock the tires and try to test the pressure while driving forward. I then took out the relief valve for the lift circuit and it appears to be fine visually.. I disassembled, cleaned, and reassembled it. No change. I then swapped it with one of the 'system' relief valves, and still no change. After that, I put together a couple gauge setups and hooked them up to the 2 outlets on the hydraulic pump. It would only crank for a couple of seconds since it was fighting the pressure, but both gauges bounced off of the 3,500 psi range.
Any ideas? I'm unsure if maybe one of the other 'system' relief valves could also be affecting the lift circuit somehow? It seems like if the pump was bad, I'd be getting bad readings directly off of it, and the other functions (driving, steering) wouldn't work. It also seems like if it were the cylinder seals on the ram, there would be some fluid release and I'd be getting proper readings off of the test ports. Oh, I also replaced the hydraulic oil filter.
Any help is greatly appreciated.
