Got a Kawasaki 31hp (1.125" shaft) to repower my old PowerClean. Need a drive pulley with three five-inch groves to turn the 47 Roots DSL blower 1:1 and one four-inch groove so as not to redline the Cat 3CP pump. Can get a four-groove 4.125" pulley from Motion Industries, but it would underdrive the blower (it has a five-inch pulley, which is the minimum), and slightly overdrive the Cat 3CP at 3,000 rpm.
Appreciate (almost) any ideas.
