Ow yeah... thanks reynoldston. Kinda overlooked that option. Well, with the price of v-belts and the Toro eating them I assumed spending a little more on a new pulley is worth the money in the long run.
Also little scared of worning out my new axle, and I found it cheap with some luck. Wouldn't gamble on that again. It's kinda nice it is still possible to buy parts for a mower from 1989, the prices are always double of the amount I think is reasonable... This pulley in The Netherlands cost me some 170 bucks. Saw it on Amazon for 100 bucks, but only available in the US to ship to.
