Transmission Features
- The RG140 is equipped with the FUNK transmission, a power shift transmission known for robust performance and reliability in heavy construction equipment.
- It typically includes 8 forward and 4 reverse speeds, allowing versatility in speed and torque management for various grading operations.
- The transmission is a direct-drive type, maximizing efficiency and responsiveness.
- Transmission fluid capacity is around 6.7 gallons, with recommended fluids specified in the service manual. Proper fluid maintenance ensures smooth gear shifts and long transmission life.
- Hydraulic control of the transmission integrates with the overall machine hydraulic system, which operates at pressures up to 2600 psi and flows of approximately 50.5 gallons per minute.
- Advanced electronic control allows optimized shifting patterns and load management, aiding operator ease and productivity.
- Engine power in the RG140 motor grader is approximately 140 hp, with turbocharged 6-cylinder diesel engines providing torque around 485 lb-ft.
- Dimensions are roughly 27.96 feet in length and 8.25 feet in width, with an operational weight near 29,775 pounds, balancing power and stability.
- The unit features a full 360-degree circle for blade rotation and an articulated frame providing a turning radius suitable for varied terrain.
- Regularly monitor transmission fluid levels, temperature, and contamination to anticipate wear or failure.
- Follow the recommended transmission fluid change intervals detailed in New Holland’s service manuals.
- Inspect hydraulic lines and fittings connected to the transmission control system to prevent leaks and pressure drops.
- Use OEM fluids and parts for replacements to maintain warranty and performance standards.
- Power Shift Transmission: Transmission enabling gear changes under load without clutching, improving efficiency and operator comfort.
- Direct Drive: A design where power is transmitted directly without intermediary components, reducing losses.
- Hydraulic Pressure: Pressure generated by fluid in transmission and hydraulic systems enabling component actuation.
- Fluid Capacity: The total volume of fluid required to fill and operate system components optimally.
- Circle Rotation: Refers to the motor grader’s blade rotating fully around its mounting circle for flexible grading angles.
