Hi, my burner motor (that sucks air in and powers the oil pump) has started whistling. The whistle starts about 2 minutes after the motor first spins up and comes and goes during operation.
Apart from giving it a good clean, just wondering if I can / should lubricate it and what sort of lubricant I should use?
Heres a link to the type of motor : https://www.ebay.co.uk/p/Burner-Moto...att/1466560610
Thanks for any advice!

ATF is very good for bearings that aren't going well.

Bearings from the sound of it. Might be a temp fix to lubricate, but could
be wear.

Whistle or a squeal?

Others have said bearings but I'd expect more of a squeal and for it
to not come and go once started.

A whistle could be from air flow through/around something, somewhere.
Give it a good clean out and see if it goes away.

Are you sure that the noise comes from the motor rather than the oil
pump, or maybe a bearing for the fan - if there is such a bearing? Oil
pumps don't last for ever!

It might also be an air leak, which will vary with the temperature.

Looks like a pretty standard burner motor with fan one end and oil pump mount at the other.
There are a few standard failures that could produce a whistle.
Fan touching the casing especially when warmed up
Bearing failure, likely the pump end one if the pump shaft seal is failing and allowing kerosene to reach the bearing. Commonly used bearings are shielded type with high temperature rating (C3 type)
Oil starvation - most likely cause part blocked filter.
See how you go and report back
