i have not done a forum before so here, im trying to fix my grandmothers record player that says it is a w700 w800 LR13392. i believe that some springs are missing. because the drive disk will not contact the motor shaft. im trying to find pictures or some thing that will tell me if they are missing or in the wrong place. thank you. i can add a picture of it if i figure out how and you need them. if the numbers do not mean anything. thank you

Welcome to ARF Phono forum.

The service manual is located here, if that is your model.
A photo would definitely assist.
Best,
Hotwax

That was the right information. It made me understand how the drive system operated. Is there a website people can order things like a motor?

Please elaborate re: ordering a motor ?
What are the "motor" problems ?

The motor will spin when i have the record turn table removed from the top of the unit. Occasionally i had to spin it with my fingers to get it to start spinning, and occasionally it would stop or go into a lulling or hunting rpm.Then when i put the turn table back on top of the unit it will do the same thing but also eventually stop, as if it was to much of a load for the motor. But, can be restarted for a while by spinning the turn table manually bringing it back up to speed.

It could well be that the lubrication in the motor/bearings
has hardened and is slowing it down.
Most people recommend dis-assemble, thorough cleaning,
and lubrication of motors with turbine oil.

You can bet it most likely has not been rebuilt.

In addition, if your record changer uses an idler wheel
to transfer motion from the motor to platter,
the idler wheel will need to be replaced.
The rubber idler wheel hardens with age and the idler
loses its friction grip.

Also make sure the inside rim of the platter is cleaned with
isopropyl alcohol. Same with idler wheel and motor drive
surfaces. If there is any oil/grease in these areas, this
could be another source of symptoms you described.

Thank you. I will disassemble the motor and clean i assume with contact cleaner and lubricate and order a idler wheel. Yes it has one. i found "the voice of music" website. is that one you would recommend?

1. You can clean the rotor and shaft(s) of the motor with 91%
isopropyl alcohol. Cheaper than contact cleaner.

2. Yes, voice of music is very reliable.

Hello hotwax I just got the turbine oil in the mail today. Do I only put the oil in the bronze/brass bushings in the opposing ends of the housing? or also around what I believe is called the stator. Thank you.

Correct, only apply the oil to the bushings on opposite ends.
Do the bushings have felt oil reservoirs in them ?

Keep oil off of the rotor, too, obviously.

If you could post a good photo(s) of the motor, that would
greatly help.
I'm giving general advice from other types of record changer
motors I have rebuilt, such as General Industries and Alliance.

Good photos.

Have you taken a q-tip and cleaned out the
bushing base where the rotor sits ?
Also, I presume you cleaned the rotor shaft
and tip ?

It looks like there were felt oil pads in the bottom
bushings, but they can deteriorate and fall out.
Also, check for upper bushing oil pads.
If the pads are in there, you can add some
turbine oil to them.
I'm not sure if anyone has found a way to replace
missing felt oil pads.

Thank you for all your help. I am waiting on the idler still and will then reassemble. I will let you know how it turns out.

Thank you Hotwax. It spins very well and freely. replaced motor mounts idler wheel and cleaned and lubed motor. Starts and spins right off the bat no jump start needed. Im working on getting power and sound from the speakers now. Might post more questions in the future. thanks again.
