reillo oil pump?

[pmac10]

hi guys,
was at a burner tonight, no oil from the nozzel, it was real dirty underneath so changed it, still no oil. the solenoid was working as was the pump. opened the pump and the filter was also minging so i cleaned it and thought as i had the pump lid off i would open the lid beneath it to check the key which drives the gears for wear. as i removed it the little moon shaped piece which sits beside the gears lifted with it.
now no matter what way i put this piece back the pump siezes (it was fine beforehand),
i had a spare pump so fitted that and everything worked fine.
i still have the other pump, is there a way to put this back together properly??

Do you have the book for the burner there could be an exploded isometric view of the pump might make it easier to see exact siting.or even try riello website??

thanks for the reply DH, i will try a detailed search using the pump part number tomorrow, have taken these apart many times over the years in the factory where i work but this must have been a newer model as it had a roll pin to locate this part in the lid which is what lifted it and i guess the gears must have moved, thought this may be some sort of schoolboy error and the oil guys may have encountered it before.

I don't take them apart, unless I'm showing a cub how they work. Invariably riello pumps break down because the gearing's worn, and for £50-60 which the custard's forking out, just aint worth the heartache trying to rebuild them!

And another point. There won't be. Riello won't stand by the pump if you've dismantled it! I've even had them get funny about the filter being exposed to be cleaned!

thanks for the replies croppie, i was hopin you would get a look at this, i didnt charge for a new pump, i had a useable one, these were polish work colleagues whose landlord was trying to take the ****, told them the burner was fine, you need 300 litres in the tank for it to work!, nobody would would help them and one of the maintenance engineers at work pointed them in my direction, ill put the pump down to experience but one of the guys at CITB Belfast told me this was good practice, ( though Ricky contradicted this.)

Hi Macrut125, I have the same problem as pcmac10 with the Riello pump on an RDB1 oil burner. Using your link above takes me to eBay but it says the posting has expired (over 90 days). I'd be really grateful if you could re-post your repair instructions.
Cheers,

when you put the pump back together don't tighten anything up yet as you need to align the gears.....i do it with a cordless drill....then lightly tighten up and spin the pump with the cordless at high speed....and keep tightening checking as you go for tight spots seizures!!

I think for £10 and my time to strip one down and then re assemble it on an old pump it makes sense to pay an extra £40 and fit a new one for peace of mind and give the customer a guarantee, If you repair an old oil pump with the kit and it doesnt last 12mths youre going to have to buy the customer a new oil pump so you are out of pocket.

 

[macrut125]

Most of the people who buy my repair kit are private individuals.......who repair their own pump.
I have repaired several successfully...if the gear wheel slots are not damaged, the repair is permanent. My CNC manufactured carbon steel drive pegs are very robust and last, unlike the original Riello pegs, which wear out. It each case, I would advise the customer of the risk.

As kimbo says, I'd be fitting a new one, not worth the hassle or expense if the repair doesn't last.

First gear is usually badly damaged, as the pin cuts a track in it. Pity a Danfoss pump isn't made to replace the Riello pumps.
