Riello RDB Pump Needle (Solenoid) Valve

[bedlam]

Hi
Can anyone tell me how much travel there should be on the "plunger" of the Valve, the one I currently have fitted seems to have virtually none, also should the plunger and stem be able to be separated for cleaning?
Mine can't..... just trying to establish if it is jammed and needs replacing, I can rotate the "plunger" with a needle through the port holes and that is about all

How are you going to set the pump up after you've finished faffing about with it?

Hello Bedlam
Can I ask what has brought you to want to start dismantling the coil stem of an oil pump?

Eh up. They're all out tonight.

You are, I would guess, inexperienced with these appliances.

These burners/Boilers can be extremely dangerous.

Please get a qualified oil technician/Heating Engineer to reassemble it/ repair and recommission it for you.

I am trying to eliminate a "lock out", I am aware that I cannot set up Pressure, Emissions etc.
although removal of the valve should not affect that - should it?
I just wish to establish how much lateral movement there should be on the "plunger" is all, it rotates in the stem ok
I am also not a numpty 30 years in power plants taught me that

And let them know if its an RDB or Mectron pump they need to bring with them once you have knackered the one you have!!!!

Very high pressure fuel pump and an overall sensitive bit of kit ( The Burner).
It's really not worth trying to DIY.

I'd like to eliminate people who think it's OK to play with things they should not.

Looks like we both will be disappointed.

You've knackered the oil pump for a start. Which makes me question your last sentence.
