Stop Press- I wondered after I'd written it that perhaps I might have turned the oil off inadvertently - I'd certainly played with the thumbwheel intending to stop the oil supply but thought better of it and left it as it was. Anway fiddled with the valve (I really don't think I understand how...
Thanks OilLecky for the vote of confidence. I didn't however disconnect the oil feed nor did I check the filter cartridge when I removed pump, only disconnected the nozzle pipe at the pump end. It sounds like I should have checked the filter cartridge anyway as good practice. Just now I've done...
Fitted new motor and reassembled. I'm pretty sure I assembled correctly especially fan/motor clearance. Initally fired but locked out after 30seconds or so. Reset twice and locked out quicker, the last time without firing although I think I heard a click like a spark before lockout. Is the...
Thanks Oilman for coming back so quickly. I suspected as much. I don't know of any secondhand rotors so will see if local spares supplier has a motor in stock. It looks like it just unbolts via 2 allen head bolts on flange. Is it as simple as that?
On further investigation I find the eroded keyed shaft on the oil pump is a removable plastic 'top hat' not metal as I thought (you all knew that already I'm sure) and I assume a replaceable 'weak link' of the motor assembly. That still leaves the eroded metal keyway bushing within the motor...
Have removed oil pump and oh dear! Forgive my ignorance of the correct terms but this what I see. Full of powdery oxidised crud. A 1 inch shaft coming out of pump with two keys diametrically opposite which are the source of said crud because they're almost totally worn away. This shaft turns...
Thanks OilLecky for your replies. Unfortunately work has kept me from getting my hands dirty this evening and doing what Oilman suggested but will get to it first thing Wed am. Still can't find an oil filter between tank and oil pump. Surely I need to put one in at some point?
I did check back along the line towards the oil tank but still no sign of any filter system, not that I know exactly what it will look like but just copper tubing seems to be all there is!
As for removing oil pump I'll have to leave it till tomorrow pm but I think I see what I have to do. I...
Thanks OilLecky and Oilman for quick reply. Forgive my stupidity but I can't see any obvious fuel filter. The copper piping enters the house at floor level within the boiler to a brass thumbwheel and thereafter continues as reinforced flexible hose into side of oil pump which incidentally is a...
Worcester Bosch Heatslave 15/19 Intermittent Lockout
First started mid Nov 2008. Any time of day but commonly first thing am. OFTEC boilerman serviced it and told me whilst ever it restarted on the reset button it would be like trying to find needle in the proverbial. He said he could try...
