Stove/Furnace Make: Riello oil burner

Post Sun. Oct. 13, 2013 3:18 pm

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.

My confusion unfortunately extends to R-tight L-Loose, because I'm not sure whether that applies from the back or front in this case. Here's a picture of the leaky hydraullic ram, with the capillary tube coming off the back of it:

If I were to approach from the front , like so http://i.imgur.com/BBC0M9y.jpg (with the nut in back of the jack), would that be counter clockwise or clockwise?

You have done this sort of repair? I have another question about parts related to the attachment of the capillary tube. The new part (of course) has a corresponding place for the capillary tube to enter. It is a female threaded connection.

There is a male threaded connector in the existing (female) jack connection, and I'm not sure how easy it will be to get this male threaded bit out.

I thought I would have all the necessary parts to swap, but will this connector be easy to get out and reuse?

I just saw this post .....and have an old mectron in the shop. I'll check it in the AM and reply here on the forum. It is easier than you think. Reillo is one heck of a burner......30 years and still efficient, .......with parts availability. The last one I changed.......many years ago. :idea: :)

Unscrew the male fitting while the jack is still screwed on the blower frame, counter clockwise as viewed from the tube side. Remove the phillips head screw by turning it counter clockwise, as you are looking at the screw head.
