Clutch Drive - Calculating Pump Output (if equipped)
The standard pump output varies from 0.010 to 0.050 cubic in. (0.1639 to 0.8195 cu. cm) per cycle, by changing the
position of the pump adjustment nut (A) (F
IG
. 1, page 6), located below the pressure gauge (D) (F
IG
. 1, page 6).
Use the following formulas to calculate the pump output per hour:
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
IG
. 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
