The Kawasaki KCM 67Z7 can be equipped with a 3.1-cubic-yard (2.4-cubic-metre) general purpose bucket for material densities between 2,800 and 3,000 lbs/cy. For loose materials between 2,600 and 2,800 lbs/cy, the 67Z7 has a 3.5-cubic-yard (2.7-cubic-metre) material handling bucket.
The 67Z7 is powered by a Tier 4 Interim, fuel efficient, Isuzu 4HK1 diesel engine, rated at 152 net horsepower. The hydrostatic transmission consists of two electrically controlled variable displacement axial piston type hydraulic motors in conjunction with a summation gear box. A variable displacement piston pump drives the motors. Axles are equipped with limited slip differentials as standard and internal planetaries and dual circuit, wet brakes. This powertrain package provides outstanding rimpull power and extremely smooth operation.
The fuel efficient engine is aided by the hydrostatic transmission to provide outstanding power at low fuel consumption. Two power modes are available to fit the application requirements. The efficient, proven Z-linkage provides excellent digging performance. Standard Auto Idle Shutdown prevents extended idling. The “natural” braking of the HST also saves on brake wear and reduces axle heating due to brake application.
The 67Z7 hydrostatic transmission allows for a Creeper function to allow the operator to control first gear speed precisely even at full engine speed. The inching pedal allows the piston pump of the hydrostatic drive to destroke and slow the machine in any speed range. The KCM IntelliDig system balances rimpull and hydraulic power to optimize loading.
