4.3 HYDRAULIC PUMP
The hydraulic pump is a gear type and consists of the primary pump as the main pump (13 cc/rev) and
secondary pump as the steering pump (7.0 cc/rev). The drive shaft set between these two pumps receives
engine power directly through the drive gear of the engine crankcase.
Pump capacity (at rated engine RPM)
Primary pump: 13 cc/rev. X 2,600 rpm = 33.8 lpm
Secondary pump: 7.0 cc/rev. X 2,600 rpm = 18.2 lpm
