a. Place the new diaphragm and rod assembly in the governor
, housing. Be sure that all the holes in the diaphragm are aligned with the threaded holes in the rim of the governor housing. The bent ends of the rod should point out. Place the diaphragm cover in position, being sure the vacuum passage holes in the governor housing, diaphragm, and diaphragm cover are all correctly aligned. Insert the eight diaphragm cover screws and lockwashers, spacing evenly the three screws drilled for lock wiring. Turn the screws in until the flanges nearly meet but do not tighten the screws. Place the governor diaphragm gauge, Snap-On Tool No. MC-141, on the governor housing as shown in the illustration and hook the end of the diaphragm rod into the slot provided in the gauge. Tighten the eight diaphragm cover screws securely before removing the gauge. This procedure will stretch the diaphragm sufficiently to insure full travel of the diaphragm and proper governor operation. Install anew safety wire and seal to the three diaphragm cover screws drilled for lockwiring.
