Important Information about Cab Safety and Cab Certification
1708867
Cat machine Rollover Protective Structures (ROPS), Falling Object Protective Structures (FOPS), or Tip Over Protective Structures (TOPS) are certified after extensive design and testing has been completed. Certification is required to ensure maximum operator protection. This process requires Caterpillar to meet SAE, ISO, and EEC standards and regulations for: structure strength/deflection, operator size, a protection zone (DLV) around the operator, operator retention, sound, vibration, visibility and ventilation. When unauthorized changes are made that may modify any of the above, the certified structure may be voided. Some examples of changes that may adversely affect the cab certification are: 1. drilled holes in the ROPS, FOPS, TOPS, seat mounting, or seat 2. welding on the ROPS, FOPS, TOPS, seat mounting, or seat 3. use of a seat or seat belt other than listed as standard or optional for the machine. Please refer to Caterpillar® Service Magazine article SEPD0777 for more information on cab certification.

Cat® Comfort Seat Features and Benefits
Cat Comfort Seats are designed and tested to provide optimum reliability and comfort for the Cat machine operator. Designed for rugged use, Cat Comfort Seats are built to last 10,000 hours with proper maintenance. • Eight seat adjustments accommodate all operator weights and sizes. • Backrest extension (available on some models) provides superior upper back support. • Thick, contoured back cushion with side bolsters limits side-to-side movement on slopes or in rough terrain. • An adjustable lumbar support distributes pressure over a broad area for added back support. • The reclining mechanism has cast gears for long life. • Adjustable armrests can be flipped up and out of the way when not in use. • Thick, contoured seat cushion features angle adjustment and rolled front edges for reduced leg pressure. • Cushions are upholstered with rip-resistant materials using a special fusing process for long wear and sleek appearance. • Cushions are comfortable, waterproof, washable and replaceable. Seat covers are not needed. • Adjustment levers are located at the front of the seat within easy reach. • Seat belts automatically lock into position, but still allow for operator movement without cinching. • Extra long seat belts are available to accommodate all operator sizes. • Seats with three-point seat belts (shoulder restraint) are available for some off-highway trucks. • A second shock absorber can be added to the air suspension for increased operator comfort in demanding applications. • Heated seats (available for some models) provide extra comfort on cold days. • Heated cushion conversion kits are available for most unheated seat models.

Replace Only the Seat Suspension Replace the seat suspension on an existing Cat Comfort Seat when replacement of the suspension group is needed due to wear, damage or when a change of suspension type is desired and available. The Cat Comfort Seat suspensions listed in the table below can be used with any current or previous Cat Comfort Seat uppers for the models listed in the table below. First, refer to the “Determine if an Existing Seat is a Cat Comfort Seat for Service Options” section of this guide to confirm that a Cat Comfort Seat is currently installed. Cat Comfort Seat suspensions can be used with all Cat Comfort Seat upper seat assemblies. If a Cat Comfort Seat is not currently installed, please refer to the “Install a Complete Cat Comfort Seat in a Cat Machine” section of this guide to add a complete Cat Comfort Seat to the machine.
Service Options for Cat Comfort Seats
Each part is a fully assembled seat suspension (everything below the upper seat assembly). A slide block kit is also required for installation. Caterpillar recommends all old seat mounting hardware be replaced with new hardware when installing a new suspension. Consult SIS for the required mounting hardware part numbers.

Replace all parts in the seat belt assembly when: 1) any part of the seat belt group shows signs of excessive wear, or 2) when any part of the seat belt group is damaged, or 3) when any part of the seat belt group is not in good working order, or 4) three years after seat belt group installation, regardless of condition. Refer to the “Determine if an Existing Seat is a Cat Comfort Seat for Service Options” section of this guide to determine if a Cat Comfort Seat is currently installed. If a Cat Comfort Seat is not currently installed, please refer to the “Install a Complete Cat Comfort Seat in a Cat Machine” section of this guide to add a complete Cat Comfort Seat to the machine. Please call the Dealer Solutions Network at Caterpillar (309-636-8900) if there are any questions about replacement seat belts. Important Information about Cab Certification and Seat Belt Replacement: Cat machine Rollover Protective Structures (ROPS), Falling Object Protective Structures (FOPS), or Tip Over Protective Structures (TOPS) are certified after extensive design and testing has been completed. Certification is required to ensure maximum operator protection. This process requires Caterpillar to meet SAE, ISO, and EEC standards and regulations for: structure strength/deflection, operator size, a protection zone (DLV) around the operator, operator retention, sound, vibration, visibility and ventilation. When unauthorized changes are made that may modify any of the above, the certified structure may be voided. Use of a seat belt, other than listed as standard or optional for the machine, may affect the cab certification.

Service Options for Cat Comfort Seats
Seat Belt Options: Some off-highway trucks have Cat Comfort Seats with three point seat belts. Three point seat belts can be installed only on seats originally equipped with three point seat belts. Two point seat belts can be installed only on seats originally equipped with two point seat belts. Retractable seat belts are standard on most new Cat Comfort Seats. Non-retractable seat belts are available and can be installed on any Cat Comfort Seat that was originally equipped with a retractable two point seat belt. Non-retractable seat belts cannot be installed on off-highway truck seats that were originally equipped with retractable three point seat belts. Some operators prefer non-retractable seat belts to retractable seat belts when operating machines in very bouncy terrain, such as in scraper applications. Some operators experience seat belt tightening with retractable seat belts when operating machines under these conditions. An extra long non-retractable seat belt is available for larger operators. This seat belt is 2362 mm (93 inches) long. The retractable and standard non-retractable seat belts are between 1372 mm (54 inches) and 1422 mm (56 inches) long. The parts in the following table include all parts needed to install a new seat belt assembly on a Cat Comfort Seat.

Add a Second Shock to an Air Suspension Seat
Add a Second Shock to an Air Suspension Seat To Enhance Durability in Demanding Applications A second shock can be added to a Cat Comfort Seat with air suspension to enhance operator comfort and suspension durability in demanding applications.
Service Options for Cat Comfort Seats
If a Cat Comfort Seat with mechanical suspension is currently installed, refer to the “Replace the Seat Suspension” section of this guide to determine the part needed to change the suspension. Then, refer to the table for the shock kit part number to add a second shock to the new suspension. Follow these steps to determine if a second shock can be added to an existing seat suspension. 1. Adjust the seat to the most forward position. See picture A. Look down, behind the seat back, at the base of the suspension. If a white serial number tag beginning with the letters SUS is located on the suspension base, a second shock can be added to this suspension. See picture B. Continue with step 5. 2. If a white serial number tag beginning with the letters SUS is not present on the seat suspension base, refer to the “Determine if an Existing Seat is a Cat Comfort Seat for Service Options” section of this guide to determine if a Cat Comfort Seat is currently installed, then continue with step 3. 3. If a Cat Comfort Seat is currently installed, continue with step 4. If a Cat Comfort Seat is not currently installed, refer to the “Install a Complete Cat Comfort Seat in a Cat Machine” section of this guide to add a complete Cat Comfort Seat with air ride suspension. New Cat Comfort Seats for Scrapers are equipped with dual adjustable shocks. For all other product families, continue with step 5. 4.
