Scott:

For what it's worth.

Mine started doing the same thing ("burping" every 10 seconds or so upon
retraction) after about 500 hours of flawless operation. Having been told
that I need to send my pump to Oildyne for a modification (addition of a
high -pressure relief circuit) and deciding that getting the damn thing out
to send in was going to be a real hassle, I decided to try manually
releasing the high pressure when the thing started pulsing. I now routinely
momentarily crack the dump valve if the system starts pulsing and all is
well. The pulsing stops, the gear stays neatly tucked in the wells, and I
don't have to fight the pump out of the airplane.

No other aspect of the gear operation is affected. Should the system
operation deteriorate further, I will do the right thing and send the pump
in, but not as long as it's working as I've described. In it's present
state, I can live quite happily with it.
