The parts work very well. BUT, the cost of shipping these two small parts was ridiculous. A box 4"X4"X10" and a cost of over $29.00. Who ever is in your shipping department needs a talking to.
The motor brushes on the Lamb motor are easy to replace and worth the price to repair the motor. The wires are fixed to a brass shim that slips into the brush housing. No soldering is required.
It would have been helpful to have instructions indicating how to disconnect the wire connected to the existing brushes. I had to examine it for awhile and pull on wire gently for fear of ruining the wire connecting the brushes to the motor. Otherwise, worked well.
