It is 21 years old. It will not agitate once it has filled w/ water and the pump runs. I tried changing the belts, because a lot of black stuff was coming off of them. Now with the new belts on, you can smell burning rubber occasionally.
Answer Mark, raise and block the front of the washer up(you can remove the front panel, if you want)) remove the belts. Grasp and turn the transmission drive pulley and turn it clockwise, aftwer approximately 1/2 to 3/4 revolution, the brake should "unlock" and the tub should start to spin. Turn the pulley counter clockwise, it should be a bit easier to turn, and have a helper look in the drum and check to see that the agitator is iscillating. If all OK, you'll need to look at the motor carriage and rollers, motor, and pump. If it is hard to turn clockwise, you'd have a worn out tub bearing assembly. If you cant turn the pulley counterclockwise, or it makes noise,then you'll need the transmission, tub bearing and tub seal kits.
