necessary.
b. If the pump cover gasket (4) and mounting gaskets (11) appear badly worn or damaged, discard them and replace
with new gaskets.
c. Inspect the pump seal (14) carefully for good condition and replace, if necessary.
195. Water Pump Reassembly
a. Apply shellac to the gasket surfaces of the water pump body (10) and crankcase, and position the gaskets (11) on
the pump body.
b. Fasten the pump body (10) and mounting gaskets (11) to the crankcase with the six hex head bolts (8 and 12) and
lockwashers (9). Tighten the bolts securely.
c. Slide the seal seat (13) and pump seal (14) over the pump shaft and up against the pump body. Insert the
woodruff key (5) into the key slot of the shaft, and press the impeller (7) into place. Install and tighten the special nut (6).
d. Fasten the pump cover (3) and cover gasket (4) to the pump body with the eight hex head bolts (1) and copper
washers (2).

Section VII. GENERATOR AND VOLTAGE REGULATOR
196. Generator
a. Description. The 24-volt shunt generator is driven by a drive belt connected to the crankshaft pulley. Two brushes
are employed which are held in separate brush holders mounted on the commutator-end frame. Torsion springs are used
to apply proper brush pressure on the commutator. The armature shaft rotates in ball bearings on either end of the
generator. A ventilating fan is mounted on the armature shaft. Pole shoes strengthen and improve distribution of the
magnetic field and support the field coils in the field frame.
b. Removal. Refer to paragraph 92c.
c. Disassembly (fig. 78). Remove the band cover (14) by snapping back the, catch. Disconnect the leads from the
brush holders that are attached to the commutator-end frame (21), by
