Hydraulic Parts

A well-maintained hydraulics system is critical to receiving peak performance from Caterpillar equipment. Efficiency losses over time can be difficult to perceive until considerable productivity is lost. Using genuine Caterpillar hydraulic system parts insures equipment performs to its fullest capability.

Cylinder & Rod

  • Maximum seal life and overall cylinder and rod life.
  • Superior joint strength withstands abuse of demanding applications.
Benefits
  • Cat® rod seals are designed to work together to deliver optimum sealing performance and lower operating costs in Cat hydraulic systems, something you risk when purchasing other brands of seals.
  • All Cat rod seals (wiper, U-cup and buffer) feature a proprietary urethane material and patented designs, that enhance performance, reduce leakage and increase seal life.
Key Advantages
  • Meet or exceed SAE standards.
  • Specifically matched to Cat system’s different fluid types, temperatures, and pressures.
  • Provide superior resistance to compression set (25% over will fit).
  • Feature special dimensional tolerances for improved installation and performance.
Key Features
  • Cat wiper seals feature a patented double-lip design that provides optimum contact with the rod to keep out contaminants.
  • Cat U-cup seals also feature a double lip. This design ensures uniform contact of the oil-sealing lip, helping deliver top performance and wear life.
  • Cat buffer seals last longer because they’re designed to be pressure-activated.

Pump & Motor

  • Unique controls and settings to optimize machine performance and productivity.
  • High availability.
  • Tested in stringent job-like conditions.
  • Reduced leakage with seals for maximum reliability.
  • Higher speed operation.
Benefits
  • Cat pumps enables precise hydraulic system control, ease of operation and peak performance for maximum value over the life of Cat equipment.
  • Will-fit pumps can compromise the system, which may lead to fluid contamination. Contaminants will slowly erode hydraulic system efficiency (which can decrease as much as 20 percent before the machine operator even detects a problem), resulting in catastrophic failures and costly repairs.
Key Advantages
  • Cat hydraulic pumps are precisely designed and manufactured to meet the demanding.
  • OEM requirements of Cat equipment, offering the highest standard of quality and reliability in the industry.
  • Cat hydraulic pumps ensure the greatest performance and durability for optimal hydraulics system operation.
  • No other brand has access to the proprietary information needed to accommodate Cat pump settings exactly.
Key Features
  • Designed for Caterpillar® equipment.
  • Best Product Quality in the Industry.

Hose & Coupling

  • 20 times more abrasion resistant than the industry’s best rubber covered hose.
  • Superior bending radius.
  • Tough guard cover for extreme applications where hose abrasion resistance is critical.
  • Hose assembly identification tags to determine exact characteristics.
Benefits
  • Minimize unexpected machine downtime with planned Re-Hose.
  • Lower operating cost with saving hydraulic oil and labor cost.
  • Avoid safety risks (fluid injection, fire, death).
Key Advantages
  • Key Advantages of the product.
  • Expert Installation.
  • Superior contamination control (Shoot a foam projectile through hoses, tubes and couplings with 3 times).
  • The wear resistant is up to 20 times more abrasion resistant than the industry’s best rubber covered hose.
  • More flexibility - Cat Hose is designed to work at half of the SAE bend radius, allowing tighter routing.
  • Multiple delivery solutions (dealer professional workshop, mobile hose van, on site container).
Key Features
  • Caterpillar invented and patented spiral hose and the reusable coupling in 1967.
  • Every hose is engineered to surpass industry standards.
  • Cat one-piece couplings are designed for superior coupling retention with Cat hose, this results in the most reliable connection and eliminates potential for leaks.
  • Cat Proprietary Hose Tooling and Software Ensure Exacting Assembly.

Frequently Asked Questions

QUESTION
Why pay more at a Cat dealer for a cylinder reseal when I can do it myself for less?
ANSWER
Standard Cat dealer reseal service includes light honing in addition to genuine Cat seals. This relatively quick procedure removes scratches and other minor cylinder bore damage to improve cylinder performance and ensure you get the full life from new seals. After honing, cylinders are washed to remove contamination. Reassembled cylinders are pressure tested to make sure they are free of external and internal leaks.
QUESTION
Low and medium pressure hose is a commodity product. The Cat brand does not add any value.
ANSWER
Caterpillar uses superior materials and exacting manufacturing processes. It subjects its Low & Medium hose to extensive endurance testing. Cat Low & Medium pressure hose surpasses performance expectations under extensive and above average working conditions.
QUESTION
Cat hose is the same as the competition?
ANSWER
Caterpillar has been designing and manufacturing hose products since the 1960s. Cat XT high pressure hose and couplings provide higher abrasion resistance, offer half the bend radius, and the robust multiple-ply construction allow it to exceed industry standards for superior hose performance and reliability. Cat couplings are engineered, manufactured and tested with Cat hose as a system to provide maximum performance in a wide range of applications.
QUESTION
Hose failures often come at unexpected times – what should I expect in terms of replacement time to get a hose?
ANSWER
If you know the hose assembly part number, there is no competitor that is as convenient as a Cat dealer. The Cat dealer is the only one a customer can call who can build a hose assembly from the assembly part number. The dealer is just a telephone call away and can build most hose assemblies in 30 minutes or less.
