ACERT™ Technology reduces emissions during the combustion process by using advanced technology in the air and fuel systems, in conjunction with integrated electronics. Caterpillar meets emission regulations at the combustion source, rather than recycling exhaust.
The Cat C32 engine uses ACERT Technology and iron-specific features to deliver strong performance and long-term durability.
The C32 engine is compliant with U.S. EPA Tier 2 and European Union Stage II emissions regulations, reducing NOx 27.5 percent from 4.8 g/bhp-hr to 3.0 g/bhp-hr over the 3508B.
Electronic engine control automatically compensates for load demand, high-altitude conditions and cold starting.
Single-Piece Piston Design
New single-piece forged steel pistons with integrated forged steel skirt are more robust to withstand high engine heat and pressure, and enable enhanced combustion efficiency, improved fuel efficiency and lower emissions. Corrosion-resistant, stainless steel top ring reduces ring, groove and liner wear for greater reliability and longer life.
MEUI Fuel System
Fuel delivery, provided by the MEUI mechanically actuated electronic unit injection system, involves a high degree of precision. Precisely shaping the combustion cycle lowers combustion chamber temperatures, generating fewer emissions and optimizing fuel combustion. The system senses operating conditions and regulates fuel delivery for optimum fuel efficiency, improved response times, lower emissions and less smoke.
Electronic Control Module (ECM)
ECM uses advanced engine management software to monitor, control and protect the engine using self-diagnosing electronic sensors. The computerized system senses operating conditions and power requirements and adjusts the engine for peak performance and the most efficient operation at all times.

Quickly releases and re-engages to reduce power train torque loads for smoother shifting, long life and a more comfortable ride.
• ECPC (Electronic Clutch Pressure Control) System
ECPC modulates clutch engagement individually, allowing for smoother speed and directional shifts. ECPC provides controls for both the torque converter lock-up clutch and the transmission clutches that are tailored to each particular upshift or downshift. This provides the operator a superior ride and reduced fatigue.
Cat final drives work as a system with the planetary power shift transmission to deliver maximum power to the ground. Built to withstand the forces of high torque and impact loads, double reduction final drives provide high torque multiplication to further reduce drive train stress.
• Steering System
Hydraulic steering control system is designed for exceptional smoothness and precise control. A separate circuit prevents cross contamination for long life.
• Battery Powered Supplemental Steering
Supplemental steering system uses pressure accumulators and allows up to three 90 degree turns in case of engine failure.
• Wheels and Rims
Cast rear wheels and Cat center-mount rims are mounted using studs and nuts to minimize maintenance and maximize durability.
The 777F frame uses a box-section design, incorporating two forgings and 19 castings in high-stress areas with deep penetrating and continuous wrap-around welds to resist damage from twisting loads without adding extra weight.
• Steel Structures
Mild steel used throughout the frame provides flexibility, durability and resistance to impact loads, even in cold climates, and allows for easy field repairs.
Castings have large radii with internal reinforcing ribs to dissipate stress in areas of high stress concentration. Castings move welds to lower stress areas for greater frame life.
Integral Four-Post ROPS Cab
Resiliently mounted to the main frame with all-new cab mounts that reduce vibration and sound, the integral ROPS is designed as an extension of the truck frame. The ROPS/FOPS structure provides “five-sided protection” for the operator.
Designed to dissipate haul-road and loading impacts for longer frame life and a more comfortable ride.
Four independent self-contained, oil pneumatic, variable-rebound suspension cylinders are designed to absorb shocks in the most severe applications.
• Durable Design
Rugged cylinders use a large diameter bore and low pressure nitrogen/oil design for long life with minimal maintenance.
Front cylinders with preset caster and camber are mounted to the frame and serve as steering kingpins for a tight turning radius with excellent maneuverability and low maintenance.
Rear cylinders allow axle oscillation and absorb bending and twisting stresses caused by uneven and rough haul roads rather than transmitting them to the frame.
Caterpillar structures are tested using System Structural Analysis (SSA) to dynamically simulate operations in field environments and identify potential structural improvements in high stress areas. With analysis of machine structures and variables, such as haul road and payload, structural improvements were made to the frame to accommodate the new cab, platform, engine and radiator.
A Coordinate Measuring Machine (CMM) is used to inspect truck frames for consistency in the manufacturing process. Easy rebuild ability is thereby achieved by ensuring the frames are within tolerance, removing the need to alter down-stream parts.

Neutral Coast Inhibitor
Prevents the transmission from shifting to neutral at speeds above 6.5 km/h (4 mph), protecting the transmission from operating with insufficient lubrication.
Body-up Shift Limiter
Prevents the transmission from shifting above a pre-programmed gear without the body being fully lowered. This function is programmable via Cat Electronic Technician (Cat ET) and Messenger or Advisor.
Body-up Reverse Neutralizer
Automatically shifts the transmission to neutral if the hoist lever is activated while the transmission is shifted in reverse.
The transmission control electronically senses engine conditions and automatically up-shifts one gear to prevent overspeeding. If overspeeding occurs in the top gear, the lock-up clutch is disengaged, and the brakes are applied.
Programmable Top Gear
Transmission top gear maximum can be set using Cat Messenger, VIMS Advisor or the Cat ET service tool to help the operator maintain speed limits.
This function minimizes shifting by not allowing the transmission to up or down shift immediately after a shift has occurred. This prevents gear hunting when operating near a shift point and minimizes transmission shifting for increased component life.
Prevents engine overspeeding by keeping the transmission from downshifting until engine speed reaches the downshift point.
Both the torque converter lock-up clutch and the transmission clutches now have software-control for clutch fill and slip characteristics to provide superior smooth shifting.
Economy Shift Mode
Modifies engine maps for greater fuel economy.
Reverse Shift Inhibitor
Protects the engine from abrupt directional changes by slowing down the engine before shifting the transmission into reverse.
