7.3
See fig. 7.3. Place the V
-
belt from the hardware kit
over the upper grove of the compressor pully, over
the dynamo pully and over the new pully on the
engine crankshaft. Rotate the dynamo clockwise
until the V
-
belt is tight, then tighten the left
dynamo bolt snug.
7.4
Check the tightness of the V
-
belt by placing a
straight edge tangent to compressor pulley and
dynamo. Place belt tension tester in the center
and perpendicular to the belt between the (2)
pulleys and next to the straight edge. Push the
tensioner towards the theoretical center making
sure that a deflection force of 3.1 lbs. gets 0.2
inches of belt deflection at the center of the belt.
See Figure 7.4.
