Greetings,
This lift use to work just fine until one day I raised the disc I had attached to it and it wouldn't go down. So far I have drained and flushed out the hydraulic fluid. I have checked the movement of the valve and fork which are connected and move the valve in and out about an inch or so. I have removed the upper lift cover and peered into the case for anything obvious.
For an experiment I blew into the pressure tube on the assumption that the exhaust port may be plugged solid. I removed the valve from the pump to be sure it wasn't the cause of the plug. When I applied 125 pounds of air pressure nothing happened. There were no bubbles or noise.
Since the lift works going up I can assume the the line from the inlet port of the pump to the cylinder is clear, and that the plug, if there is one, is at the exhaust port itself.
Does this make sense to anyone or am I missing something? Has anyone tried to put pressure on the line to clear a clog? Is there another cause for the lift not lowering?
Thanks in advance,
