Electro-hydraulic pilot valves assist operations of ripper
and dozer tilt controls. Standard hydraulic systems include
two valves for carrydozer and dump, and a regeneration valve
for quick dump.
Standard Ripper Control
Two additional valves for ripper function
• Hydraulic shank pitch adjustment
• Optional pin pull on hydraulics
Track Roller Frame
Oscillation 362 mm 14.3 in
Features
• Lifetime lubricated rollers and idlers resiliently mounted
to roller frame by a series of bogies
• Tubular design resists torsional loads
• Bogies oscillate on sealed and lubricated cartridge pin
connections, travel controlled by resilient pads
• Roller frame attaches by a pivot shaft and fully pinned
equalizer bar
• Eight rollers per side
• Large pivot bushing operate in an oil reservoir
• Equalizer bar-roller frame ball joint pins and high capacity
bearings have improved seal and operate in oil reservoir
• Improved center bearing in equalizer bar for improved
life. Improved pin corrosion resistance, provides ease
of serviceability
• Recoil system is fully sealed and lubricated
• Large idler caps with three-bolt mounting
Steering and Brakes
Electronic Finger Tip Controls (FTC) combine steering clutch
disengagement and braking for each track. Pull back slightly
to disengage steering clutches, fully back to brake track.
• Low-effort Finger Tip Controls for steering
• Hydraulically applied multiple-disk clutches
• High capacity brakes are hydraulically released, spring
applied, and have computerized electronic brake control
for excellent brake modulation
• Single pedal simultaneously applies brakes to tracks for
fast stops
• Parking brake applied electronically, which engages
parking brake and locks the Finger Tip Controls
• High capacity (high power dissipation)
• Large diameter disks 610 mm (24 in)
