Toyostove blower motors don’t seem to go as long as they did in the past. Laser 56 and 73 blower motors used to last a long time. Now a Laser 730 blower motor is likely to last only about three years. A Laser 560 will only go a little longer.
When Laser 30 heaters came out, it became evident the blower motors didn’t last anywhere near as long as a L56 or L73. They might only go three or four years in some cases.
I never rebuilt any Laser 56 or 73 motors, as the shaft is pretty long and if the bearing didn’t come out easy, it was too much trouble to get them off. Toyotomi did provide a set of bearing and information on how to replace them. When ordering them you would get a set of two bearings which were alike.
Laser 30 and the newer OM 22 and OM 23 motors were much easier to get the bearing off. I did make a habit of rebuilding those motors. When rebuilding those motors it was noticed the bearing were not the same size. One bearing was much smaller then the other. This was a strange approach, and I could not figure it out. It didn’t seem like a good idea and since the motors didn’t last as long as L56. L73, I blamed the short life on the smaller bearing.
Now that I am back in the service business again, I have noticed the L300 and L530 motors don’t last as long as I expected. It has become evident that the Laser 730 and Laser 560 motors don’t go as long as I expected either.
I just noticed the other day that L730 and L560 blower motors have two different size bearing just like the L300 and L530. The use of a smaller bearing on the bigger heaters seems to be the reason these motors don’t last as long as they did in the past. The bearings are all NSK bearings and I can only assume they are of good quality.
If this is a cost cutting idea, it is not working for the customer. Having to replace the blower motor every three years or so is an expensive approach.
