? Offering of the model D5B
? Updated wear charts, see Attachment II
? Link Assemblies with split master links includes the master bolts as part of consists.
? Sealed and Lubricated Link Assemblies have a stopper (with blind recess) in the end of the pin to retain the oil. If service is required then use plug and stopper as shown in the parts list.
Caterpillar is pleased to announce the expansion of the ?Classic? line of lower cost repair parts to meet the needs of owners of older Caterpillar machines. The D5B/955/951/D6 have been added to the current list of D6, D7, D8, Track-type tractors and 955 and 977 Track-type loaders (see model selection for specific pitch size and serial numbers), Classic Undercarriage provides a value-priced repair alternative when the age, application, utilization or remaining life of the machine demands a more economical replacement solution.

Availability/Ordering
? Initially components will only be stocked and available in Morton and Denver.
? Orders should be placed through the ANTARESSM system for both stock and emergency orders
? Emergency order charges and freight cost apply
? Parts are returnable to Caterpillar under standard parts return policy.
? If Classic parts are unavailable, Caterpillar original parts should be substituted
Part Numbers
See attachment I by model for individual Classic Undercarriage part numbers offered in this program. Cat Classic Parts are cross-referenced to the original Cat new part number (where applicable) in the following Caterpillar parts and service information systems, including ANTARES, DBS system, and NPR.
Pricing
Cat Classic Undercarriage is priced competitively with the leading after-market manufacturer and is a less costly alternative for older non-current machines operating in less demanding applications. Caterpillar Premium undercarriage is still recommended for high production applications.
Product Packaging and Identification
Cat Classic Undercarriage components are normal Cat branded parts and utilize traditional Caterpillar parts packaging, labeling and identification. Individual components, however, will be labeled Classic, as shown below.
Note: A non-descriptor insignia shown below (right photo) will be used for identification and warranty purposes. Until current ?Nexus? branded inventories are depleted, the initial undercarriage products may have the words ?Nexus? forged into the components. This will eventually change, as product with the new insignia/marking becomes available. The new insignia shown below and packaging label will designate the part as a genuine Cat Classic Part.
Former/Current Future
Promotion
Promotion materials being offered to support your efforts in creating awareness and generating an interest for this new parts product line are:
? Cat Classic Cornerstone brochure (PEDP9129)
? Cat Classic Datasheet ? Undercarriage parts (PEHP9567)
Warranty
Cat Classic Parts are covered under Caterpillar?s parts warranty, six months due to defects in material and workmanship. Track Assurance, however, will not be offered.
Servicing
? No special tooling is required to service Classic components.
? Link Assemblies are serviced; individual track service components (links, pins, bushings, seals, etc.) are also available for normal track servicing.
? Caterpillar track seals should not be used in Classic link assemblies. The counterbore size does not permit mixing of track seals or thrust rings.
? Track rollers and carrier rollers will only be serviced at the group level, roller shells will not be offered.
? Idler assemblies are offered without bushings.
? Idler groups offered with bushings and shaft (not a complete top level group). Caterpillar bearing blocks and Duo-Cone? seal groups must be used for the final group assembly.
? Track shoe hardware is available.
? Caterpillar hardware must be used for roller group assembly and segment installation.
Custom Track Service
Wear charts are available (refer to Attachment II). The charts provided are designed for determining percent worn and are not intended for life projections.
Use the following Undercarriage Codes in CTS 5.0 for the Classic components:
? D5 - C1315
? D6 -C1545
? D7 - C1655
? D8 - C1755
Program Expansion Update
Caterpillar will be reviewing the D4D/941 machines to determine if they will be part of the Classic Program.
A review has been completed on the D9H Track Type Tractor and 200 Series Hydraulic Excavators, these machines will NOT be offered in the Classic program.
Summary
Cat Classic Parts offer your customers the opportunity to maximize profits throughout their machine and engine?s life by offering a value priced alternative when the age, application, utilization or remaining life demands a more economical repair solution. Classic Parts are Caterpillar parts offering the traditional Caterpillar warranty and backed by the full range of dealer support capabilities.
