Wayne/Walter
Thanks for the help. I have a O-360H2AD (six quart capacity) engine. My
rebel has about 200 hours since the floats were installed.
After removing the pump handle, I was able to lift the pump rod out. I then
put it back in and turned the rod about 15-20 turns to the stop. I then
turned the rod back 1/8 turn so as to install the pump handle. That was my
problem.
What is to keep the rod from backing out again? Is the piston in the pump
kept from turning by a guide or key-way?
If so, the rod was never completly screwed in when installed.

Dale, sounds like you should take the pump apart and make sure the rod can't
come off the piston again, as next time you may not be so lucky with the
landing area. Unbolt the pump from the fuselage floor and put a pan under
it, then loosen the hoses enough to allow turning the check valve fittings
out of the pump to make the minimum mess.
I have never had a pump apart, but I can tell you there is no way the piston
is keyed in place or you could never make it seal. Would think the rod would
have a check nut to keep it tight or loctite. Maybe a call to MAM would
clear this up as if it was a check nut then it's now loose inside your pump!
cheers,
Wayne

pump failure
Hi Dale,
Well, I can only imagine the pucker factor with the failed pump on your
amphip gear and grass landing. I must confer with Wayne, and I will be very
interested in what MAM may have to say about the pump rod/piston failure. Keep use
informed with what you find out and your fix. Thanks

Dale Kopff
pump failure
Murphy group,
Prior to the pump failure, it required 20+ strokes of the pump handle to
retract the amphibious gear. Now, since I have screwed the piston rod in
completly, it takes only 13 strokes.
If anyone takes more than 15 strokes, it would be a good idea to remove the
pump handle from the piston rod and see if the rod is screwed completly in.

pump failure
I took off the pump handle on mine. The rod will turn,
although it is quite tight. Is this OK, or should it
not turn at all? It definitely was not loose, so maybe
the whole piston was turning which would explain the
tightness.

pump failure
Hi Walter
If the rod is tight on the piston turning the rod will turn the piston.
There's nothing to prevent the piston from turning but it should be fairly
tight because of the o-ring that seals it.
