Text. Components of track-type tractor.
Track-type tractor D6E produced by the Caterpillar Company consists of 5
main components:
1. The engine
2. The undercarriage, track and track roller frames
3. The transmission
4. The steering compartment
5. Work tools (rippers, blades)
The starting system and hydraulic arrangement may be added as well. Cater-
pillar four – stroke turbocharger diesel engine
with six cylinders delivers plenty
of power for quick response, big loads. Direct-injection fuel system with injec-
tion pumps and valves precisely meters fuel for maximum productivity per unit
of fuel. Aluminum-alloy pistons have three rings each. All parts of the engine
are lubricated under pressure with full-flow filtered oil. Dry-type air cleaner
with primary and secondary elements prevents engine parts from penetration of
dust particles. Electric starting system available in the machine cranks the en-
gine and operates gauges on the dashboard in steering department.
The undercarriage
with heavy-duty rollers and segmented sprockets ensures
long life and minimum maintenance. It is used for mounting tracks. Track roller
frame has box section construction. It includes sealed and lubricated tracks, roll-
ers and the idler. The equalized bar located under the main frame lets roller
frames oscillate for a smooth ride.
The powershift transmission
or change gears. There are 3 speeds forward, 3
reverse. High – torque capacity of clutches permits quick speed and direction
changes.
Operator's compartment.
A ROPS and FOPS tested cab is comfortable and spaceous steering system
combined with braking system. In helps the operator both disengage steering
clutches and use the brakes with the hand levers. Single lever at the operator's
right hand controls raising, lowering and tilting functions. Monitor panel
mounted in the cab keeps the operator informed of the machine status. Multiply-
disk oil clutches require no adjustment.
