Tightening Water Pump Packing Nut
There is a packing nut at the water pump shaft to prevent water leak-
ing out. (Illus. No. 3, page 56.)
To stop a leak, turn the nut in the same direction the shaft turns, just
to the point where the leak stops. This should be done with the engine
not running. Do not draw the nut too tight.
If the leak does not stop with a moderate tightening, see page 37 for
re-packing the nut.
Adjusting Fan Belt
To adjust the fan belt, loosen the nut in back of the fan bracket
(Illus. No. 3, page 56.) To tighten the fan belt, raise the fan assembly.
Do not draw the fan belt too tight as this will cause undue wear in
the fan and generator bearing. A proper adjustment is obtained when
it is just possible to rotate the fan with the belt held stationary. After
obtaining the proper adjustment, be sure to tighten the cap screw.
