Change belt turntable - Pioneer PL-990 Turntable

It depends which type of turntable it is. If a belt one then change the belt, make certain you make a note of how the belt fits before removing it.

Direct drive turntables are more difficult. As it could be any number of faulty parts that cause it.
A build up of grease or dirt in any type of deck can slow the speed down.

A faulty motor on both types of deck will also cause it.

Any infinitesimal change in belt temperature would not cause such a change in speed. The speed of your turntable is governed by an electronic circuit and this is where the trouble is.

The cost of a repair is going to be mostly labor which may exceed the value of the value of the turntable.

There are some YouTube videos on changing belts for Marantz turntables, they might help.

OK

Belt is easy, Just remove the base, and change the belt.
Needle change is done by cartridge change. remove the old cartridge and insert the new one with the new needle.

The liely cause of the slow speed problem is the belt. Your turntable is belt driven, like components in your car's engine compartment. As the belt ages, it can begin to slip. Replacement of the belt will probably restore the speed once again. The PX-E860 turntable has been discontinued. There are parts, such as the belt, that are still available. How much longer these parts will be available for remains unknown. If you like the the turntable, you should consider purchasing several belts as the next time you need one, they may not be available or may cost much more.

1. Remove the turntable platter off from the turntable
2. Remove the old/damage belt
3. Wrap the new belt underneath the turntable platter - you will see a small lip on the bottom of the platter. Wrap the belt around this lip.
4. Put the platter back on the turntable
5. The turntable platter will have small holes, rotate the platter until you see the motor, and the motor shaft.
6. Pinch the belt, so that it wraps around the motor shaft
7. Turn on and enjoy!
