So I unloaded the lazarette and tried to bleed the system.

There are no nipples on it so not quite clear how to do it. I cracked the hose connections one after the other while moving the wheel...

Re: Hydraulic Pilot Pump Problems

I would be very grateful for your instructions. I'll send my email by PM.

Re: Hydraulic Pilot Pump Problems

OK, so you think a hydraulic shop might be able to rebuild it? It's a "reversing hydraulic pump", like this:

Hydraulic Pilot Pump Problems

I believe my pilot pump, a Raymarine Type 3 (actually Hy Pro), is knackered.

It's a shame, as it was brand new only about 5 years ago.

I think I may have murdered it myself :banghead: I've...
