My grandad has a vax dual power pro advanced and he needs to remove this part as the belt has melted it, but we have noidea what it's called and where to get a replacement.
Looks like a bearing from the gearbox. Unfortunately I doubt you could just buy that part, but the whole gearbox isn't expensive. there's an example below. You will need to check the part is the right one for your machine.
FYI you have posted in the 'Forum Information' section which is for things relating to the use and operation of the forum. Your enquiry would have been better posted in the 'Appliances' forum where guys in the know about these things hang out. However, hopefully I've helped.
