Component Layout. The component

location and hydraulic system design

provide the highest level of system

efficiency. The main pumps, control

valves and hydraulic tank are located

close together to allow for shorter tubes

and lines between components reducing

friction loss and pressure drops in the

lines. The layout further provides greater

operator comfort by placing the radiator

on the cab side of the upper structure.

This allows incoming air to enter the

engine compartment from the operator

side and hot air and corresponding engine

sound to exit on the opposite side away

from the operator. This reduces engine

compartment heat and sound transmitted

to the operator.

Pilot System. The pilot pump is

independent from the main pumps and

controls the front linkage, swing and

travel operations. The pilot control valve

operation is proportional to control

lever movement delivering outstanding

controllability.

Hydraulic Cross Sensing System.

The hydraulic cross sensing system

utilizes each of two hydraulic pumps

to 100 percent of engine power, under

all operating conditions. This improves

productivity with faster implement

speeds and quicker, stronger pivot turns.

Boom and Stick Regeneration Circuit.

Boom and stick regeneration circuit

saves energy during boom-down and

stick-in operation. This increases

efficiency, reduces cycle times and

pressure loss for higher productivity,

lower operating costs and increased

fuel efficiency.

Auxiliary Hydraulic Valve. The auxiliary

valve is standard on the 336D L.

Control Circuits are available as

attachments, allowing for operation

of high and medium pressure tools

such as shears, grapples, hammers,

pulverizers, multi-processors and

vibratory plate compactors.

Hydraulic Cylinder Snubbers.

Snubbers are located at the rod-end

of the boom cylinders and both ends

of the stick cylinders to cushion shocks

while reducing sound levels and

extending component life.
