    ADAPTER BRACKET motor and the equipment, raises the shaft height ptthe- M9484 motor by 0.75 inch to match that of the M941 motor. This is required on all valve linkage applications, Q607 External Auxiliary Switch applications, and on some damper linkage applications (either to provide clearance for the crank arm to rotate through the downward position, or to allow the damper linkage to reach the shaft).
