Clutch Drive - Calculating Pump Output
The standard pump output can be varied, from 0.010 to 0.050 cubic inches (0.1639 to 0.8195 cu. cm) per cycle, by
changing the position of the pump adjustment sleeve (2) (F
IG
. 1, page 6) located below the pressure gauge (3). The
high volume pump has a fixed output.
To calculate the pump output per hour, use the following formulas:
Table 1: Minimum / Maximum Pump Output
Standard Pump Adjustment
Table 2: Standard Output/Stroke Adjustment
360°
= Effective Ratio
Degrees of Throw
* Degrees of Throw can be found by using clutch lever diagram (F

. 7, page 11)
IMPULSES/HOUR
=
PUMP STROKE PER HOUR
RATIO
Pump strokes per hour x 0.010 = Minimum Pump Output per Hour
Pump strokes per hour x 0.050 = Maximum Pump Output per Hour
