Removal of the end-bearings, noting the orientation of the main body of the motor is first.
(I draw an arrow on the motor body pointing to the stepped output shaft)
Also note the orientation of the spacers on the bolts, one end is beveled for a reason.
Correct re-assembly is a must, later on.
Each bearing assembly needs an overnight soaking in solvent, allowing thorough penetration of solvent into the
sintered bronze and felt oil retainer.
Also wipe the shaft with solvent.
Once cleaned, and dried off, the felts can be saturated with a good quality light oil, like turbine oil.
Some oil can be applied to the bronze bearings as well.
Then re-assembled, lightly tapping the side of the shaft to help center the bearings.
The stepped motor shaft should be clean and dry.
The idler shaft should be lightly oiled.
One fiber shaft washer should be on each side of the idler.
Then the "C" clip goes on.
Clean the turntable rim inside, and the idler rubber rim.
Of course, this is just a partial "repair", since it's best to clean and re-pack the turntable bearings, clean & re-grease the mechanism. and do speed tests with a stobe disk.
The Internet is a marvelous thing, however it's not a good substitute for actually being there.
