Stripped threads on bleed screw on oil burner

Lou1978

I have had to bleed the oil burner a lot recently. Today, I went to bleed it but the threads on the inside of the bleed screw hole have stripped and the screw won't tighten! What do I do? Any help is appreciated.

What burner is it?
You could try some PTFE tape on the thread.

It's a SIME?

That's the boiler not the burner, however it is probably a Bentone on the Sime. Again, short term fix is PTFE.

Lou1978

Do you have any idea what a long term fix would b? If I was to replace the part, do you know the name if the part I'd have to replace?

The oil pump

Billy Bunting

It will likely require a complete pump but what burner is fitted to the boiler ?

Lou1978

How can I find out what burner is on it? Is an oil pump expensive or will that depend on the type of the burner?

Lou1978

A Riello 40, would that be it?

jjf1974

an oil pump for a Riello burner is around 90 euro to buy.http://www.pjmatthews.ie/oil-boiler-spares

An oil pump for your burner would set you back somewhere in the region of €140-€160.If its a case that you run out of oil regular it might be no harm to get a boiler bleed fitted at the same time it will stop the bleed screw getting wrecked again

Lou1978

Are all riello oil pumps the same or is there a specific number that I would need to get? Sorry for all the questions, I really don't have a clue.

PTFE...ERR.. noooooo.....replace, a leak is a lot more costly that a new pump!

And in future use the vacuum port for bleeding, not the pressure port.

I think it was the vacuum port is was using. It is a gold coloured screw, not the black one.

Then it's definitely a new oil pump you will need someone who knows what they're doing to fit it preferably Oftec reg.Where are you located because there are plenty of good oil men here someone might be able to sort you

jimf

The hills of Donegal! If I were to order a new one online, I'd b afraid that I'd order the wrong one. Are there different types or a number anywhere on it that I need?

Repacing an oil pump is not a diy job, you will require the burner to be set up, ie, oil presure and flue gas analysis, without it your just guessing.

There's no point in you ordering one and trying to fit it yourself as you need specialist tools to commission it.Ring your local oil boiler repair and service company.If you had a set of tap and dies it is possible to retap the damaged tread just as Jim said

Billy Bunting

PM sent.

Not quite sure. Being female, I'm not great with these things.:( It says RBL on the pump, is that of any significance?

Is the rethreading hard to do? I know my brother has one of those sets. Would I need a specialist to do that too?

in the right hands i would say its not hard but as already pointed out by billy
and robbie the important thing is to make sure the burner is set up properly afterwards

If you get bits of metal from threading in the pump you could damage it

I did state short term fix! Get him going over the bank holiday weekend.

Lou1978

Really appreciate all this. Good to know I have options!

Billy Bunting

I honestly would advise the OP not to use PTFE and hope for a short term fix, we are talking about huge pressure here and if it pops there could be a substancial leak.

BSP is a type of screw thread (British Standard Pipe). When you get the pump sorted you should consider getting a Tiger loop fitted,no more bleeding.

jimf

would agree as well billy but as shane said short term fix

the problem with short term fixes are bucket its working fine now and short term becomes years
