Power Train
Built for performance, power, reliability and fuel efficiency.
Cat Engine
The 430E features the Cat ® C4.4 DIT (Direct Injection
Turbocharged) engine with ACERT ® technology and meets
all U.S EPA Tier 3/EU Stage IIIa emissions requirements.
The increased horsepower and torque rise deliver improved
loading and roading performance.
Electronic engine control provides precise fuel metering
for optimized power, response and fuel efficiency.
The water separator service indicator ensures the
operator is alerted when service is necessary.
Dry-type axial seal air cleaner with automatic,
integrated dust ejection system for more efficient pre-
separation. Both air cleaner and precleaner functions are
incorporated into a single unit mounted under the hood.
Transmission
The Cat standard power shuttle transmission provides four
speeds forward and reverse. Hydraulically shifted clutches
allow on-the-go direction and travel speed shifts. The optional
auto-shift transmission matches gears with grade and load
conditions. Top gear is selected with the twist grip control
on the steering wheel.
Hydraulic proportional control valves smooth speed
and directional shifts.
Transmission Kick-Down Switch/Neutralizer allows
the operator to downshift through the gears to first.
Standard Four Wheel Drive (4WD) improves mobility
and loader performance in poor underfoot and can
be activated on-the-go.
Maximum roading speed of 40 km/h (25 mph) for faster
travel between job sites.
Cat Rear Axles are designed specifically for demanding
backhoe loader applications. Axles feature outboard
planetary gear sets for easy serviceability and brake
design improvements for longer service life.
Brake Mode Selector
The brake mode selector switch has three positions: two
wheel drive, two wheel drive with all wheel braking and four
wheel drive. Two wheel drive with all wheel braking provides
better tire life while roading and engages the front axle when
brakes are applied for improved braking performance.
