noisey boiler

[wcarew]

Hello I have a worcester 20/25 combi.Its been sitting in a damp house for about 9 months switched of.I turned it on and it started making a noise coming from the motor or oil pump??????????called a plumber he serviced it for me.Had new exspansion tank new diverter valve new auto air vent new flow switch.He said its the bearings.Would that be the bearings on the oil pump or the motor.Any body got some detailed pictures of this.I have the service manuel for the boiler it shows a picture of the burner,motor,oil pump together but not detailing where the bearings are.Can I undo the grub screws on oil pump and take that off without touching the oil lines.Its got flexi lines.Then take motor off and sort those pesky bearings out.Ive looked them up and the word on the street is 6202 2zz is this right.they are on ebay £7 for 2. What size are they.Its been such a good boiler.Any help much appreciated

Bearings on motor.
Probably easier just to swap the motor out.
I certainly never fiddle about with bearings if the motor has gone /is going.
