Change oil on power trim pump (model 290)

[the-sailer]

Does anyone know how to fill oil on this pump?
There is just one screw. Removing that will drain the oil.

Thanks

On my trim tab's hydraulic pump, one disconnects the hose from the cylinder at the cylinder end, and puts it into a container of oil and then flips the switch to "tab up" which causes the pump to suck oil into the reservoir.... should work for you as well. I have a copy of the Volvo OEM shop manual for the 280/290 drives, if you send me your email address, I'll send it to you... assuming PMs work on this new software/
