Riello pump covers

When doing service on a Riello pump that has phillips screws that are all rounded off how do you get to the pump strainer to make sure it is clean????

I have use plyers and squeeze real tight. You will only turn a small amount every time but once it snaps free you can get it out. Try a flat head screw driver. The right size will fit and hit the end of the screwdriver in tight so it will grip. good luck

When we first....

Started seeing more than a couple Riello burners, I notices that the pump cover screws were made out of butter or something similar in hardness. I went directly to a marine supplier that sold Westerbeke diesels that was nearby. He measured the thread and pitch. He went out back and gave me a box of hex head bolts that were the same except that you could use them more than twice. I bought a box of 100, and after the first 25 tuneups got some more.

Riello has changed the cover bolt on their pumps to allen heads in the last few years. I would still go to someone who carries metric hardware and get a box or 2 of the same size bolts with hex heads.(as I remember the heads were 5/16, the same as most pumps sold in the American market) The techs coming behind me to service a Riello burner were eternally greatful after the switch. Just a suggestion. Chris

Pump screws

You may want to invest in a posi drive phillips head screwdriver from Snap On Tools. It will remove most damaged screws unless they are totaly rounded. I would then replace them with Alen heads.
