My sony pslx250h turnable belt was ordered and i can't find the repair book to repair it.

There are appliance parts stores that repair people go to. Check your phone book

you have a real antique there. Go to radio shack and take the belt with you so it can be measured, they have a parts order book there where you can find the correct belt. its so awesome that you still have this beautiful peice of equipment.

The Operating and Install Guides are here...

Follow this procedure to install the belt on the turntable.

1. Lift up on the dust cover [FIG. 1] and remove it from the turntable base [FIG. 1].

If the ribbon is not present make sure you fashion one of your own so you don't contaminate the belt with oils from your skin.

in order to be 100 % sure
you would have to check voltage to the motor while its suppposed to operate
take off the bottom 6 screws, you might need whats called a safe t, a torque wrench or star with a hole
most use phillips,
drop the bottom, you should see the turn table motor
disconnect the two leads and connect them to a voltmeter,,,
turn the unit on
you should read voltage to the meter
if not the problem is in your control board and will need to be replace
if you do read voltage and the motor is not turning
you will need to replace the actual motor
either way its a pretty simple repair and can be done without taking the unit dwon

Most parts stores can print this out for you for free.

its simple the belt goes around the platter and the motor spindle, thats it!

It is possible you are looking at the page for the 1994 960 and not the 940. The 960 had one (serpentine) belt. Your 940 has three. Hopefully chiltons has the repair order for the 940s as well.

I know it's not alot, but I hope it helps

Usually, for most turntables, the belt goes on the bottom of the platter first. Then you put the platter back on the turntable. From here you should see an opening on the platter where you can 'grab' the belt. Pinch the belt, and then wrap it around the rotating motor's shaft. This is usually at the top left side - around the 10 o'clock position.
