My Riello Mectron 5M oil burner developed a leak in the hydraulic jack (after 20+years). I have a replacement part - a new jack of the long type, #3006499. This part opens a shutter on the blower during operation.
DIfficulty - I have no idea what I'm doing, though I have read this oil jack is a simple part to swap out. I must detach it from the housing, which is easy enough, but removing and replacing the capillary tube that brings oil from the pump has me worried.
Does anyone have experience replacing a riello hydraulic jack? Facing the device head on, the order of parts is jack, then a screw/nut that attaches the capillary tube to the jack, and then the capillary tube, which carries oil into the jack from the pump.
As I face the burner, WHich way should I turn the hex (clockwise or counter clockwise?) THe hex nut is is very, very tight. I presume I must reuse the hex and the screw it turns on, which attaches the capillary that feeds the jack, as there is only an empty threaded place on the replacement part.
Should I remove the jack from the housing before attempting to detach it from the capillary?
Any help at all would be very welcome.
