John Deere 870G, 870GP, 872G & 872GP Motor Grader PDF Repair Manual TM13070X19
A motor grader repair rarely stays confined to one component. A transmission job can involve the driveline, an articulation repair can require access to hydraulic cylinders and frame components, and a 6WD problem on an 872G can lead directly into the pump, charge circuit, engagement manifold and front drive motor. John Deere TM13070X19 is designed around these machine-specific repair situations for the 870G, 870GP, 872G and 872GP motor graders.
Rather than using a generic construction-equipment repair guide, this technical manual gives you model- and PIN-specific service information for the assemblies that make these G-Series graders different: the 9.0 L PowerTech engine, DF230 transmission, tandem drive system, 6WD system, steering, braking, main hydraulics, circle gearbox, moldboard controls, articulation and ground-conditioning equipment.

Why the 870G and 872G Should Not Be Treated as the Same Grader
The most important technical difference in this model group is the drive configuration. The 870G and 870GP are 4WD graders, while the 872G and 872GP use a 6WD arrangement. That difference changes the service requirements around the front axle and adds a dedicated hydraulic drive system to the 872G family.
For an 872G/872GP repair, TM13070X19 provides information for the 6WD pump, charge pump, engagement manifold, hydraulic motor and related front-drive components. For an 870G/870GP, the relevant repair path centers on the conventional powered-wheel, axle, tandem and driveline assemblies.
This makes the manual particularly useful when a technician needs to determine whether a problem is mechanical, hydraulic or related to the configuration-specific drive system.
PIN Coverage — Check This Before Ordering
| Model | PIN Coverage |

Grading System Information for Real Repair Work
For a motor grader, the moldboard and circle assembly are working tools, not simply body components. A fault in one hydraulic function can affect the way the blade responds during road formation or finish grading.
TM13070X19 provides repair information for the draft frame, circle frame, lift arms, saddle, blade-pitch system, circle side-shift components, circle gearbox and grader hydraulic valve sections. The hydraulic coverage extends to individual valve sections associated with functions such as blade lift, blade pitch, circle rotation, articulation and wheel lean.
If a circle gearbox requires removal, for example, the manual provides the component-specific repair path rather than leaving the technician with only a general hydraulic troubleshooting procedure. The same applies when a blade-lift cylinder, circle motor or grader-control valve requires service.
9.0 L Engine Service Coverage
The 870G/GP and 872G/GP use the John Deere 9.0 L six-cylinder PowerTech engine family. Depending on emissions configuration, John Deere lists PowerTech PSS, PowerTech Plus and PowerTech versions for these grader families.
TM13070X19 identifies engine removal and installation procedures for the applicable 6090HDW01 and 6090HDW04 configurations. The surrounding auxiliary systems are also addressed, which is important because major engine work frequently requires removal of cooling, charge-air and fuel-system components.
- Radiator removal and installation
- Fan and fan-related component service
- Hydraulic and differential oil cooler service
- Transmission oil cooler service
- Fuel cooler service
- Charge-air cooler removal and installation
- Fuel tank removal
- External fuel-system components
Transmission and Driveline Repair
The DF230 transmission is one of the major repair areas covered by this publication. The transmission section includes removal and installation as well as hydraulic-system information, including the charge-pump area.
Behind the transmission, the manual continues into the drive system with procedures for input shafts, U-joints, tandem assemblies, bearings, reduction components and drive chains. This is useful when a noise, vibration, loss of drive or component failure cannot be isolated to the transmission itself.
6WD-Specific Service for 872G and 872GP
When the problem is on an 872G or 872GP, the 6WD section becomes particularly important. The front drive system introduces hydraulic components that do not exist in the same form on the 4WD 870G/870GP.
Covered areas include:
- 6WD hydraulic pump
- 6WD charge pump
- 6WD engagement manifold
- 6WD hydraulic motor
- Powered front-wheel axle components
- Planetary drive components
- Planetary brake components
- Front-wheel hub and bearing assemblies
This configuration-specific information can be valuable when a grader has reduced front-wheel assistance, requires a 6WD motor replacement, develops a hydraulic leak in the engagement circuit, or needs front-drive components dismantled for inspection.
Hydraulic System and Component-Failure Cleanup
Hydraulic contamination can turn one failed component into a much larger repair. TM13070X19 includes procedures for the main hydraulic system as well as cleanup procedures associated with hydraulic or hydrostatic component failure.
The manual covers the main hydraulic pump, hydraulic manifold, soft-start valve, fan pump, fan motor and fan valve. The information is therefore useful for both component replacement and the cleanup work that follows a hydraulic-system failure.
Steering, Articulation and Brake Systems
The articulated frame and steerable front axle make the 870G/872G platform different from many conventional wheeled machines. TM13070X19 provides service procedures for the steering system, including the steering valve, steering cylinders, wheel-lean cylinder and secondary-steering components where equipped.
The chassis section also addresses frame-related service, articulation-bearing work and structural procedures. Brake information covers the service-brake system, brake valve, hydraulic circuit, bleeding and accumulator, with separate information for the park brake.
