My 620 has a generator type onan in it without the front PTO. I've been kicking around doing the briggs swap. Can you all tell me if there is an aftermarket front PTO I could bolt up to the briggs if I go that route?

Or would anybody be so kind to measure their clutch?

Need:

Height of the clutch assembly

DIA of pulley

Belt width

Thanks
