I'm wanting to remove this from my Super Bronc 2 VT-1040... I removed the bolt at the end of the engine drive shaft, but the drive 'clutch' isn't budging. Am I missing something? Do I need a grear puller or some other tool? Also, the belt that came on it is a NAPA 25-07800/24308 5/8" wide belt. Something that I read showed that the 40 series should have a 7/8" or 1" belt? Should I change out the belt, or am I good?
