Edition Fifteen is a comprehensive update to the CTS Handbook. Nearly every wear chart
in the book was updated. The General Information section, the Management & Merchan-

• The rounding was removed from all measurements for the Ultrasonic Wear Indicator.
• The carrier roller wear limits were increased for use with Heavy Duty, Rotating
Bushing and Extended Wear Life Track.
• Track roller wear charts for elevated sprocket machines now extend to the point at
which the wear surface meets the retainer bolt holes.
• Greater and Lesser Allowable wear columns were combined into one for large
excavators.
• The machine layout is now similar to the PSK, starting with small machines and
ascending to the large ones.
• The machine models are up-to-date.
• Pipelayer model numbers were added to the applicable section headers.
• The three excavator sections, the 300-Family, 200-Family and E-Family, can be more
easily located with the new, individual tabs.
• Undercarriage Codes for use with the CTS computer program were updated and
included in the front of each section and below each wear chart.
