Washing Machine and Tumble Dryer Belts

If you are having a problem with a washing machine belt, this is usually a fairly easy problem to prove and to fix. The problem can usually be seen by raising the front of the machine and looking for the black rubber debris underneath the machine where the belt has worn and all of the grip surface rubber has been worn away by the motor pulley. The belt may even have been torn and end up wrapped around the motor pulley. Whatever the circumstance you need now to identify the belt in order to be able to replace it. The first line of research should be the model number of the machine, and if you type this model number and the word belt into a search engine you are most likely to get a positive result.

If this does not yield a positive result or you need to be reassured that it is the correct belt proceed with the following remedy. If you can recover enough of the belt to be able to read any of the identifying numbers printed on the outer surface, then great, what you require is firstly, the part number or if that is not visible the belt size and type usually 4 digits followed by a capital letter J or H and then another single digit, eg: 1240J5. If none of these are still visible you first of all need to count the number of grooves in the original belt, this gives you the last digit of the belt size. Next you need to determine whether the grooves in the pulley are V-shaped or U-shaped, ie rounded in the bottom of the groove. If a V shape then this is a what is called a J type belt and if rounded then it is an H type belt. You now need to look at the motor mounting to determine whether there is any adjustment on the motor to enable the belt to be tensioned or if the motor is fixed with no adjustment, the adjustment usually consists of a slotted frame so that one of the motor mounting bolts is able to slide up and down in order to tension the belt.

Once this has been ascertained you now need to measure the length of the belt which entails measuring around the two pulleys, the one on the drum and the one on the motor shaft. This is best done with the tailors' cloth tape measure or if not available the normal metal tape measure. The length would be expected to be around 1100mm to 1300mm possibly as long as 1450mm on some older, slower machines with larger pulleys on the drum. If the motor is adjustable this is the length of the belt that you require, be sure that the tension setting of the motor is set to the minimum length. If the motor is fixed and not adjustable then you require an elasticated belt, the one nearest in length below the measured length, it then has to be stretched to fit around the two pulleys, in this case the size would then be for example 1100J6EL or 1100H6EL, etc.

Remember! Always remove the plug from the mains electrical socket before proceed ing with any work or investigation!
