Ecoflam Minor 4 electric motor bearing replacement

[mopfe]

Hi - happy 2019 & I know this boiler (Iona 90) is old - but so am I!

Problem
Ecoflam Minor 4 electric motor -Simil - bearing on fan side - noisy.

From posts by @oilman - "The bearings are 6206-2RS and 6206-2Z"
No disrespect intended, posts were from 10 years ago, but is this still accurate?

A) Which is the bearing for the fan end?
B) How difficult is to change the bearings?
b (i) - Any special equipment needed - pullers, press & the like?

Any and all help appreciated.

for the cost of a new motor for these i would just replace the whole motor, changing bearing on a motor over 10 years old is not really worth it as the windings would have already been damaged with noisy bearings

It turned out that the noise was because of a buildup of "crud" between the impeller fan housing and the motor body with some ingress onto the motor shaft. Cleaned out, using a thin rope and sawing that back and forth. Also, I was able to insert the back of a hacksaw blade into the gap between the shaft and the impeller, so as to shift the debris. - now super quiet. However, I would still like to know about the bearings part no(s).
