Re-lubricating old DUAL turntable

I also lightly sprayed some WD40 into the motor as well, and let it sit. This may not be the correct lubrication method or oils, but it will have to do.

After I reassembled the turntable I tested it, and things seems to have quieted down quite a bit. Not sure if this is permanent, but it's good for now. The only thing that bothers me is that I have grown quite attached to the 1229. I have a Music Hall 2.2 LE, and can honestly say that the Dual beats the pants of of that thing in every way shape or form (except for the sexy red paint on the MH) with any cartridge/stylus combination I have tried.

Again, thanks for the response!

Guaranteed not permanent and with Water Dispersant #40 in it, you now definitely have a problem. WD40 is thickeners and solvents to thin it out. The solvents will rapidly evaporate leaving a new batch of goo behind. There aren't many things that are worse than WD40 in a motor.

Post a picture or 2 of the motor. ISTR slots stamped into the shells that may have been there explicitly for prying off the shells.

You should have a warm spot for the 1229 as it was one of the finest automatic tables built and compared well with just about anything else in its day. Properly restored it need offer no apology.

I've attached a picture of the motor and one of switch that I used to convert the table to manual mode only (purists look away!):

I thought about putting the motor in a vise, and using a screwdriver to tap at the indentations in the motor housing to push them apart. Right now though, the table is back together and the noise is gone, probably due to the help I got from the micr-oiling pen I used to get the oil into the motor in the first place.

I'm keeping my fingers crossed...

Are you trying to take that round black motor apart?
I have done it many times. Unfortunately I don't have one on hand
to photograph, so I'll explain.
Get two flat blade screwdrivers and a block of wood roughly
1 & 3/4 in. square, a large dowel will do.
Slip one screwdriver blade into each of two vertically adjacent slots, place
the block of wood between the two screwdriver shafts and adjust till
you can get enough leverage to squeeze the two screwdriver handles
together and begin popping the motor apart. Work slowly, a little at a
time and work around the motor going from slots to slots.
It may help to heat the motor casing just a bit with a hair dryer on high.
Make sense?

YEAH, that's the ticket! It's been so long I forgot that obvious 'trick'. I'm embarrassed I didn't remember.

Well, yesterday I came across a vintage Dual 1229Q with wooden base, intact dust cover, original cartridge clip, and turntable mounting instructions.... no user manual though. I don't know why I had to buy a 1229Q. I already have a 1229 I purchased new in 1972, but made my own solid walnut base. I guess it was to have a complete Dual set up. And the 1229Q is just magnificent.

I just had to tel someone, and though no one has posted here for awhile I have a few question since am new here. I had a bit of noise from the motor and had a bit of a time getting the motor apart. I thought it was bearing noise but it actually turned out to be something a bit bizarre. There is a ferrite ring magnet at the top of the motor stator and after disassembling it (several times) I found very small pieces of chipped ferrite clinging to the ring, and field coils. So from time to time a piece would shift and rub inside between to stator and the field pole pieces. I finally got all the pieces, but those buggers were everywhere! I'm wondering what caused the chipping? I think it may have been some harsh handling. The motor stator has quite a bit of vertical up and down free play so perhaps it slammed into the mtor housing top inside?

The inside looked very clean, no gumming and sleeve bushings and motor shaft showed no scuffing. Almost like new! There was a repititious squeak-squeak-squeak also, about the speed of the idler wheel rotation, but after cleaning it has disappeared. Now the unit is quiet and smooth.

Well, I'll go for now, but am wondering where I may be able to get a new ( maybe old stock) idler wheel. I think I know the answer. . . but I sure wishI had bought a couple years ago when they were cheap and plentiful!
