Can anyone let me know roughly what belt sizes I need for my 20B FD set-up.
I am running FD waterpump with alternator and P/S in stock location. Air pump and Air Con pumps removed. Have a standard underdrive pulley set on.

Thank you

measure from the outer edge of each pulley, the total distance along the style of pulley it will be running on with will be enough to be able to get the correct belt from any shop

 

Put a string around the pulleys..get a measurement.
belt size is in cm or inches so either way you can get what you need.
Go to a Auto part store and the can sell you a belt that size.If it does not fit just return it and go one size up or down.

My setup is real ****-eyed,Changed frequently too,so I have done this and I have had no problems doing so.

 

Fair point. I have not got all my pullets on yet as I cannot fit my P/S pump yet. So I was hoping to get belts in advance ready for when I next work on the car.
But I guess there is a risk everyone else setup is a touch different. So I better wait.

Right I am having some bother here. I measure around as suggested and come up with a 5PK0750 required for the alternator belt with the air pump no longer in place. However having rung around a few places the nearest I can seem to get is a 0737 or and 0768 which neither are going to fit. So either I have done something daft or I do need that belt and it is just a real odd size?

Anyone got any info they can offer?

Thank you

Don't forget to take into account your adjustment for tension, failing that you may have to put in an idler
