SOURCED TECHNICAL DIAGNOSIS

Cat 336 excavator: official engine, hydraulic and capacity data

Wave V QA found this existing Cat 336 route producing byte-identical HTML to the unrelated Honda NC750X DCT route. It is now separated with Caterpillar-published 336 specifications and machine-specific diagnostic context.

CAT 336Source scope stated

Concrete facts to establish first

  • Caterpillar lists the Cat C7.1 TTA engine for the current 336 product page.
  • Published net power is 223.5 kW / 300 hp to ISO 9249.
  • Published displacement is 7.01 L and operating weight is 36,800 kg.
  • The main hydraulic-system maximum flow is 560 L/min, with 35,000 kPa maximum equipment pressure.
  • Published refill capacities include 600 L fuel, 25 L engine oil, 373 L hydraulic system including tank and 50 L DEF.

Measurement, isolation and repair sequence

  1. Confirm sales model, serial-number prefix and machine generation before applying any service value.
  2. Match the engine and emissions configuration to the serial-number-specific Cat service procedure.
  3. For hydraulic complaints, log pump command, engine load, implement pressure and temperature in the same work event.
  4. Use published refill capacity as a reference, then finish level setting with the machine-specific sight-gauge/dipstick procedure.
  5. After repair, verify operating temperature, leaks, hydraulic response and active machine fault codes under load.

Worked diagnostic example

The 336 and 336 GC can carry different engine/specification sets. Confirm the sales model and serial-number prefix before transferring a published value into a service decision.

Post-repair verification

  • Sales model, serial prefix and engine configuration are matched.
  • Capacity and measurement references are within the cited configuration scope.
  • Post-repair temperature, hydraulic response and active fault state are verified under load.

Sources and application scope

  1. Caterpillar official Cat 336 Excavator product specifications

Numeric thresholds and test criteria apply only to the cited engine, model year and application. Prioritize the vehicle-specific OEM service information.

Reduce misdiagnosis

A single DTC does not condemn a component. Compare freeze-frame, companion codes, electrical measurements, network/communication state and mechanical or flow tests from the same fault event.

Electrical / network architecture

  • 336: Evaluate engine ECU, machine controller, pump/valve control and CAN/J1939 network together.

Sensors and actuators to observe

  • 336: Main-pump pressure/flow control.
  • 336: Pump displacement / swashplate command.
  • 336: Pilot-pressure sensor.
  • 336: Main-control-valve spool/solenoid commands.
  • 336: Travel/swing pressure and speed feedback.
  • 336: Hydraulic-oil temperature.

Relevant symptoms for this configuration

  • Slow hydraulic functions or stalling under load
  • High oil temperature, cavitation noise or erratic movement
  • Asymmetric travel/swing power

Model-specific reference checks

  • 336 OEM published configuration: OEM-published Engine displacement reference is 7.01 L. Measurement/evaluation on the same configuration should use this published value as context; obtain any service tolerance from the VIN/serial-matched OEM procedure.
  • 336 OEM published configuration: OEM-published Net power reference is 300 hp. Measurement/evaluation on the same configuration should use this published value as context; obtain any service tolerance from the VIN/serial-matched OEM procedure.
  • 336 OEM published configuration: OEM-published Net power reference is 223.5 kW. Measurement/evaluation on the same configuration should use this published value as context; obtain any service tolerance from the VIN/serial-matched OEM procedure.
  • 336 OEM published configuration: OEM-published Main hydraulic flow reference is 560 L/min. Measurement/evaluation on the same configuration should use this published value as context; obtain any service tolerance from the VIN/serial-matched OEM procedure.

Root-cause discrimination

  • Differentiate pump wear from main-valve leakage/setting faults by evaluating stall/deadhead testing with flow and case-drain findings; use OEM procedure for safe limits.

Post-repair verification

  • Recheck cycle time, pressure/flow, drift and leakage behavior cold and at operating temperature.

Sources and scope

Exact pressures, torque values, pinouts, fluids, adaptations and part procedures must be confirmed against the VIN/build-date/unit-code matched manufacturer service information.
