Where was the oil that needed to be flushed? the rotor had rust on it. when I reassemble the motor, just a drop in the upper and lower bearings and how about the rotor? any lube for it?....20w non detergent oil is that something ace hardware would have, is it like 3 in 1 oil ? also once I'm done soaking parts can I dry them with my ryboi heat gun set 200F ?

Deash,
There is a felt pad in both ends of the motor, outside the bearing--it MUST be dry, and then it should be soaked with the oil--
Yes, most ACE stores sell the 3 in One brand of (electric) Motor Oil, SAE 20 Do NOT use the "regular", "household", or, "multi-purpose", type of 3 in One

P.S.
Whilst you are at ACE, purchase a sheet of "Crow-kus" Cloth" (not sure of SP ?), and use it to clean-up that rusty shaft--it should "shine"-- Ron Rich

Thanks Ron, I will pick the 3 in1 electric only and some Crow-kus cloth...I've never heard of that before is it like emery cloth ?
I'm drying the upper and lower bearings and rotor now on top of a portable oil radiator is that o.k. it's in the upper 70's in mid-tenn. today and don't have the furnace running I asked about a heat gun...yes,no good idea or not ?

Deash,
I would not heat the rotor too hot---a hair dryer on low will not hurt--but not on high--
On the cloth--yes, and no--there is no "visible" residue when using "crow-kus" cloth.

Be extremely careful about burnishing/polishing the motor shaft.... if it spins in the bearings freely, leave it alone.
Any wear of that shaft will cause rumble and noise while playing a record.
The main thing to address is making sure its oiled and free to spin when assembled.
And make sure the stepped drives on that shaft are clean... and the idler is pliable and not glazed/shiny on the edge. (rubbing gently with emory paper gets rid of any "shine")
If it's hardened, it needs replacing.... it just won't have enough grip to get the platter up to speed.
Same goes for the inside rim of the turntable platter...... clean/dry.
And..... clean/oil the platter shaft and a drop or two of oil on the bottom ball bearings.
The platter should spin free by hand with the changer turned off.
The Internet is a marvelous thing, however it's not a good substitute for actually being there.

No Ron, those V-M style motors (It's actually a Voice-of-Music record changer) have a rounded tip on the lower shaft that rides on a tempered steel plate inside the bearing cup.


That doesn't look like a Voico of Music changer. I think it is an Ensign (Admiral). It appears similar to a V-M from the top, and uses the same type motor, but the mechanism is completely different.

Still waiting for the upper & lower bearings to dry...you made it clear that they were to be DRY! Bought some non-detergent turbine oil for electric motors at Ace Hardware today they did'nt have any Krow-cus cloth but bought a sheet of 600 wet/dry sandpaper and will use that on the rotor only the shaft looks fine and Matt gave some warnings about messing the rotor shaft up.

Brian,
You be right on the changer. SAMS data indicates Ensign EN406-1.

This will be my last posting to this thread.... it's gotten for lack of a non-cencored word.... tiring.

No sandpaper.
read my previous posts.
Done.

Yea, platter now spins at right speed upon turning it on no more waiting, and whirring sound from the platter is gone, but now the platter spins backwards and will not reject....I really need to learn to take more pic's....I'll figure this out.

Funny thing about motors..if you install them backwards they run backwards...reinstalled correctly and then rej. linkage lined up correctly...that problem is done and the r/c comes up to correct speed when you turn it on no more waiting and awful whirring sound is gone thanks Matt and Ron. I have some other issues with this console and will start a new post.
