Feltwell said:Central heating boiler fan starting to get noisy, sound like it's rubbing on it's case. Take the boiler apart this morning, the rubber mounts the fan motor sits on are ever so slightly worn, just enough so the fan has enough movement to catch the case when it starts or stops. Can I buy the little rubber mounts that must cost about a ha'penny? No, of course not, that'll be £110 + VAT for a complete new fan assembly Sir :evil: .
A red fibre washer under each mount to pre-load them ever-so-slightly and stop the excess movement and all is fixed for a good few years to come
I have used rubber grommets in the past when needing to mount equipment sensitive to vibrations. Also used rubber widgets & wotnots from various cars/bikes when something a little more substantial was required - Exhaust mounting rubbers & battery tray mounts are very useful.
