Generator
The electrical output of the generator is controlled by the setting of a third brush
and the maximum output permissible is 17 amperes when the generator is cold.
On cars equipped with radio or fitted with the two-charge generator control, the
generator charging rate should be set to a maximum of 22 amperes cold or 17
amperes hot. This adjustment requires the use of an accurate ammeter and voltme-
ter, and should be made by an Authorized Terraplane and Hudson Service Station.
A few drops of light oil should be supplied to cups (A), Figure 6, every 1,000
miles. Do not over-lubricate.
The generator is driven by the "V" type belt, which also drives the fan and water
pump. This belt must be kept sufficiently tight to prevent slippage on the pulleys.
When properly adjusted the belt will have from to 11/4" of slack at a point
midway between the fan pulley and generator pulley, as shown at (E), Figure 6.
This adjustment provides sufficient tightness to prevent slippage without causing
undue wear of the fan and generator bearings.
To adjust the belt tension, loosen nut (B) and swing the generator away from the
engine until the proper position is obtained. Tighten nut (B).
