i've been researching this for a month and cannot find a definitive answer. How many MM is the driver side pulley? 70, 80 or 90?

 

PQR101150 is 80mm>>

thanks over, i thought so...now hopefully i can find one for a little cheaper than $50!

 

the tensioner has great tension on it but isn't new by any means...i have heard of putting replacing old idlers with one size bigger to increase tension...wondering if there are opinions of this out there.

 

is this the correct pulley for the tensioner?

They have all the bearings and different grades generally in stock.

 

The tensioner is spring loaded. Increasing the pulley diameter won't have any effect on the belt tension. The spring is doing that.


You don't want crazy tension. If the belt is in good condition it doesnt need to be guitar string tight to spin stuff.

Full tensioner unit isn't expensive. I would swap the whole thing if you suspect anything. V easy job. Mine had a plastic wheel and was in a terrible state. Bearings were shot. Was scratching it's way around.
