2.5 V-Belt Drive System (10-50 HP)
2.5.1 V-Belt Tension Adjustment
The KI-Series and KIV-Series compressors (belt driven 10 through 50 HP) are equipped with an
automatic belt-tensioning device and requires no adjustments between belt replacements. Belt tension is
established by springs between the compressor assembly base and the motor mounting plate.
By compressing the springs, additional tension is created on the belts. Spring compression dimensions
are listed Table 2 below:
Table 2. Spring Height Dimensions.
UNIT DRIVE DIMENSIONS
KI(V) 10 - 50 Belt 2.125 to 2.250 in (5.4 to 6.4 cm)
When a spring is relaxed it should have a dimension of 2.375 in (6 cm).
Measurements should be made from the face of the drive mounting plate to the top of the washer under
the lock nuts. See Figure 1.
