Motor mounting:

A Mk 2 double grommet conversion kit has been installed to improve isolation between motor and chassis.

This kit consists of 3 new precision machined higher profile mounting studs. 6 isolation grommets, clips and washers.

This upgrade is significant in that the noise floor is lowered another 10 db.  A difference that can be easily heard.

The Platter, Bearing and clutch:

The platter is iron and undamaged.  The strobe ring remains bright and un-marred.
The platter bearing has received maintenance and upgrades as noted below. (see "The Bearing:)
The clutch has received new friction material. Clutch mounting points have been cleaned and re-lubed at hinge and slider areas.
The upper platter shell (aluminum) has been straightened and will not rub.
The 45 hub integrated into the upper platter operates per design.
The original rubber platter mat remains supple and free of damage.

The Bearing:

The bearing shaft did not show evidence of wear (measured via micrometer). 
The shaft was micro-pollished with  Crocus Cloth to restore the smoothest possible surface.
New Oilite bushings have been installed into the platter bearing housing.  Bearing action is 'just right'.
The thrust bearing pad has been replaced with a Torlon 4301 thrust pad for longer wear.
The main bearing end cap has been replaced with a heavy Gun Metal Bronze cap.
New, heavy, longer lasting gasket seal is installed.
