bought a lazy boy 3hp. tiller with the trans. in a box. need help to assemble the trans. i put it together the way it appeared it was but it tilled about 5' and locked up. disassembly showed the sprocket[9t x 54t] drive chain had bound up and damaged the teeth some . i filled off the burrs. some problem with the chain to the tine shaft gear[20t]? there were three chains in the box, but only two would fit. does somebody have an exploded view of the trans. that would guide reassembly. the housings have 18 bolt holes. need model# to order parts. how many links per chain? 3hp.b&s motor runs fine. the pulley shaft has 11t. the tine shaft and the pulley shaft can be assembled with left and right ends swapped.
