Lubrication:
Do not lubricate - must be clean and dry to function:
- trip projection on turntable hub
- arm clutch assembly (holds the record size)
- all spindle parts
- all rubber parts (use CaiKleen RBR rubber restorer)
- muting switch
- the part that activates the power switch
- shutoff link on change cycle cam
- test track plate on change cycle cam and record setdown adjustment screw (if screw is on the cam)
- raising height adjustment screws
- pickup arm lift rod
- pickup positioning finger pin adjustment (on arm clutch assembly)
DO NOT LUBRICATE (or use only graphite powder):
- trip finger (on clutch assembly)
- trip arm
- trip striker (rests on trip arm)
- raising plate in arm assembly
Oil:
- pivot points of the idler wheel arm assembly
- idler shaft
- motor
- turntable center bearing
Grease:
- change cycle cam track for raising the arm
- change cycle record pusher roller
- change cycle cam center bearing
- gear teeth
- shafts of gears
- sliding parts of the idler wheel arm assembly (the speed control cam)
- record pusher actuating slide (but not the part that moves the pusher)
- pickup arm raising lever(s)
- pivot arm for change cycle drive wheel (but leave the end connected to the trip striker unlubricated)
- cycle stop stud on change cycle cam
- pivots and shafts of controls and their linkages.
- control shafts
- if the record setdown adjustment is on the plinth, grease the eccentric at the bottom, where the cam projection
rubs against it.
Put a very tiny bit of grease on the pickup positioning finger pin and let the change cycle carry it around throughout
the pickup arm horizontal track of the cam. But make sure there is NO GREASE on the part where the pickup
positioning finger pin moves as the arm tracks the record when out of cycle. Also make sure the pin, or any grease
on it, does not touch the cam at this point. Any such touching here will prevent the pickup from tracking the record.
The special grease in the pickup arm bearings normally does not fail. If it has failed, or has been removed, use my
special mix of damping fluid to replace it. The fluid is a mixture of 50% sewing machine oil and 50% Vaseline
Petroleum Jelly, well blended. I use this for both the vertical and horizontal pivots, and the lower arm shaft bearing
below the arm clutch.
