Content-Type: text/plain; charset="us-ascii" ; format="flowed" My pump was one of the hydraulic pumps with the spool valve installed backwards. Many thanks to Chris Zavatson for helping me fix this problem. It delayed the first flight of my 360 back in Feb. (the third delay), but I did get a ride in his 360 from Concord, CA, to his hanger up in Woodland, CA, and back. One very simple test to check for this problem is to raise the gear part way. Some time near the half-way point of the up cycle, put the gear switch back in the down position. If the gear does not start back down instantly, then the spool valve is probably in backwards. My gear would wait 10 to 20 seconds before starting back down. After we reversed the spool valve, the gear would reverse instantly any time during the cycle, and I was able to lower the up pressure switch setting. You will be able to get the gear to appear to operate normally by raising the up pressure switch setting with the spool valve in backwards, but you will not be able to instantly reverse direction during an up cycle.
