hi... i am ordering 2 new brushes for my 116119 Lamb Motor, in a Beam 294 power unit. Motor needs a whack to start. i took motor out and inspected brushes, and found 1 brush worn down to only 1/16" left, and the other has 5/16" left. never seen that much difference. the bearings in the motor seem fine, there is no play. do you think this uneven wear in indicative of another problem?
thank you for this wonderful website. we bought our new house with central vac a year ago, and i have no experience with them. your website information on motor replacement and repair was exactly what i needed.
