Caterpillar D6H II
Maintenance schedule, common problems & OEM parts breakdown
The Caterpillar D6H II is a medium-class track-type tractor (crawler dozer) produced from 1986 through the late 1990s. It is powered by the Caterpillar 3306 six-cylinder diesel engine, delivering 165 hp (123 kW) gross power with a displacement of 10.5 L (640.8 cu in). The machine features a powershift transmission with three forward and three reverse gears, reaching a maximum forward speed of 11.4 km/h (7.1 mph). Operating weight ranges from 17,761 kg (39,156 lb) for standard configurations to approximately 19,814 kg (43,682 lb) for the Low Ground Pressure (LGP) variant. The D6H II succeeded the D6D series and was eventually replaced by the D6R in 1996. Configurations included standard, XL, XR, and LGP tracks, along with various blade options such as the semi-U and straight blades.
The D6H II introduced Caterpillar's Hi-Drive undercarriage system, featuring an elevated drive sprocket to reduce wear and improve durability compared to the D6D. This generation marked a shift toward more robust hydraulic systems and improved operator comfort with the introduction of the OROPS (Operator Rollover Protective Structure) cab. In the used and parts market, the D6H II remains significant due to its widespread adoption in earthmoving and forestry applications during the 1990s. Its mechanical simplicity and the availability of aftermarket support keep it relevant for fleet managers seeking cost-effective medium-duty dozers. The transition to the D6R series brought electronic controls and emissions changes, making the D6H II a benchmark for pre-electronic heavy equipment reliability.

Servicing the D6H II beyond the schedule
Predictive Maintenance & Fluid Analysis
Monitor engine oil, hydraulic fluid, and transmission oil via Scheduled Oil Sampling (S.O.S) at 1,000-hour intervals. Check for coolant contamination in the hydraulic system, a common failure point in the D6H II's closed-center hydraulics. Inspect the air filter restriction indicator daily; clogged filters accelerate turbocharger wear on the 3306 engine. Verify SCA levels in the coolant every 500 hours to prevent liner pitting. Track hydraulic pump flow rates against the factory spec of 167 L/min (44.2 GPM) to detect internal wear before catastrophic failure.
Corrective & Common Repairs
Address hydraulic cylinder seal leaks promptly, particularly on the blade lift and tilt cylinders, which are prone to external scoring. Inspect the final drive pinion seals for oil weeping, a frequent issue on high-hour D6H II units. Check the transmission clutch packs for slippage if gear engagement becomes soft. Replace worn track shoes and idler rollers to maintain proper track tension and reduce ground pressure. Inspect the 3306 engine's valve train for excessive noise, indicating worn lifters or pushrods. Repair or replace the torque converter if overheating occurs during heavy grading.
Overhaul & Rebuild Points
Plan for undercarriage overhaul when track link elongation exceeds limits or sprocket teeth become hooked. The Hi-Drive system requires specific attention to the elevated sprocket bearings and seals. Rebuild the transmission torque converter if metal particles appear in the oil sample. Inspect the engine block and cylinder heads for cracks around the coolant jackets. Overhaul the hydraulic pump and control valves if flow rates drop below 150 L/min (40 GPM). Check the final drive planetary gears for pitting or spalling during major service intervals.
Seasonal & Environment Servicing
In cold climates, use low-viscosity engine oil (15W-40 or lower) and ensure the coolant mixture provides adequate freeze protection. Clean radiator and aftercooler fins daily in dusty or sandy environments to prevent overheating. In high-humidity or coastal areas, inspect electrical connections for corrosion and check battery electrolyte levels frequently. Use biodegradable hydraulic oil in environmentally sensitive areas if required. Adjust track tension seasonally; loose tracks in mud increase wear, while tight tracks in rock increase bearing stress. Drain fuel water separator more frequently in wet conditions.
D6H II fault codes & troubleshooting
| Code | Meaning | Likely cause | What to do |
|---|---|---|---|
| 36:0110-03 | Engine Coolant Temperature Sensor — Voltage Above Normal | Open circuit in the sensor wiring harness or a failed sensor element causing a short to the power supply. | Inspect the wiring harness between the Engine ECM and the coolant temperature sensor for breaks or chafing. Test sensor resistance and replace if out of specification. |
| 36:0190-08 | Engine Speed Sensor — Abnormal Frequency | Incorrect air gap between the speed sensor and the tone ring, a damaged tone ring, or a failing sensor. | Check the sensor mounting and air gap. Inspect the tone ring for missing teeth or damage. Verify sensor output with a multimeter or oscilloscope. |
| 36:0164-03 | Injector Actuation Pressure Sensor — Voltage Above Normal | Short to power in the sensor signal circuit or a failed sensor. | Disconnect the sensor and check for voltage on the signal wire. If voltage remains, trace the harness for a short to power. Replace the sensor if the circuit is intact. |
| 36:0268-02 | Programmed Parameter Fault — Erratic, Intermittent, or Incorrect | ECM has detected that a programmable parameter is missing or corrupted, often due to a low battery or previous diagnostic tool interaction. | Connect a diagnostic tool (CAT ET) to the service port. Check if parameters are programmed. If not, program the correct parameters using the tool and an active SIS subscription. |
| 36:0041-03 | 8-Volt DC Supply — Voltage Above Normal | Short to power on the 8-volt reference circuit shared by multiple sensors. | Disconnect sensors one at a time to isolate the short. Inspect the harness for damage where it shares the 8-volt supply. |
| 36:0041-04 | 8-Volt DC Supply — Voltage Below Normal | Short to ground on the 8-volt reference circuit. | Disconnect sensors sharing the 8-volt supply one by one to locate the shorted component. Inspect the wiring harness for chafing against the chassis. |
| 36:0248-09 | Cat Data Link — Abnormal Update Rate | Communication fault on the data link, often caused by damaged wiring, poor connections, or a termination resistor issue. | Check the data link connectors for corrosion or bent pins. Measure resistance across the data link terminals to verify termination resistors. |
| 36:0110-01 | Engine Coolant Temperature — Below Normal Operating Range | Thermostat stuck open, allowing the engine to run too cool, or a sensor reporting falsely low temperatures. | Monitor live coolant temperature data. If the engine is physically cold but the gauge reads low, replace the sensor. If the engine does not warm up, replace the thermostat. |
Codes and remedies are general guidance for this model family — always confirm with diagnostic tooling and your dealer before major repairs.
D6H II attachments & work tools
