Belts How long should they last ?

I bloke I work with got just 18 hours out of main drive belt for his Rayco RG50

At $450.oo a pop what are your hints to ensure this doesn't happen again,

Whats the correct tension ?
Pully alignment important ?
Will keeping the teeth really really sharp all the time help ?

any comments would be greatly recieved

Screw those expensive belts ... worth changing over to Vee belts, perhaps triple with B profile.

A few have done the change over.

I run only 2 belts on my Kanga not 3 as it's direct drive and no adjustment ... yeah, like what sort of idiot designs a belt drive machine with no adjustment? You have to lever the belts on which every belt place will tell you destroys them ... anyway I get like 50 hours out of them easy and if starts to slip too much pop a third belt on.

Look at getting pulleys fitted or machined up, my belts cost $20 each and available everywhere.

Crikey, I even seen dirty great chippers run with v-belts not toothed.

Had sprockets and chain drives on my 4404 Carlton. Did the same and changes to v belts and pulleys...purely for the cost factor.

The polychain belt sharpens the drums teeth snapping the belt,change over to a triple pulley set up and run fan belts.
