MP25

Many thanks to those who’ve contributed to this thread. I’ve just replaced the bearings in my Vent Axia Kinetic MHVR following the directions above. Unit is 6 years old and had become more noisy with some louder squeaking which sounded like a bearing being tortured. I encountered two issues: when disconnecting the motor cover the circuit board was left on the motor - there are a number of pins connecting it to the motor holding it in place, though was fairly easy to lift off and carefully put to one side. The second was that the bearings were a different size than those above! I’ve shown the motor number and bearing measurements from my unit, so a bit of a setback though quick enough to come from Bearing King - I ordered some high efficiency SKF bearings, more expensive though still only £24 for four. Enclosed are some photos of the process - including one of the poor old bearing that had clearly failed (one of the motors was much less free spinning than the other). While I had the unit off the wall, we took the opportunity to clean the vent pipes using a pull tape and home made microfibre “sweep” - photo included for those interested.
