Fitting:
The PTFE thrust pad simply drops in on top of the original thrust pad. Use a small smear of grease to hold it in place.
On some players you may find that once you've fitted the PTFE thrust pad the magnet assembly of the motor now binds on the upper bearing. If this happens you will need to space the lower bearing assembly away from the upper bearing and the kit includes two shim washers for this purpose (see photos).
