Installation is very do-it-yourself. No need to remove the motor; it is done in place! Unplug the unit and remove the four screws holding the bottom plate, exposing the motor. Locate the motor. Clean the surface. Let dry. Use a small amount of glue (approved for nylon to metal such as Loctite Epoxy Plastic Bonder) to attach the nylon housing to the motor. The perfectly machined housing takes the guesswork out of positioning. Once the glue dries, plug the motor in and tighten the screw with a small plain screwdriver until the knock disappears. Replace bottom.
I was stunned at the immediate difference this kit made in eliminating the knock in a Thorens TD-145 motor I could hear across the room! Just a couple of turns of the pin, and the noise was gone! I positioned my ear just inches from the motor and I could not even hear it running! Unlike a similar kit on the market, this kit uses a nylon housing to reduce resonance, there is never a need for additional lubrication, and the internal spring exerts constant and consistent pressure.
Some have asked if the kit will help to prevent motor knock from developing in their Thorens motor, and it is my opinion it will because it raises the motor spindle off of the internal bushings. Instead, the spindle is riding on the stainless steel ball bearing tip.
