Technical Coverage and Machine Specifications

This service publication provides exhaustive technical reference data for the Series 6 wheel loader line. Documentation spans fifteen functional groups, ensuring you have the correct specifications for the engine and pump distributor gear, travel and working hydraulics, steering and brake systems, and integrated electrical modules. It details vital maintenance intervals for machine operations, lubricating systems, and hydraulic component pressure settings.

When undertaking any complex repair, having accurate OEM data is critical to getting the machine back on site quickly. The manual includes comprehensive technical data tables detailing engine performance for the D934 and D936 models, specifically noting displacement, power, and torque output. For fluid power management, hydraulic system pressures are thoroughly documented for variable displacement pumps and motors across various serial numbers. You can also cross-reference electrical reference values for solenoids, sensors, and the main electronic control unit for advanced field diagnostics.

Engine oil capacity for the D936 is strictly listed at 43.0 liters. Intake valve clearance for these Liebherr diesel engines is specified at 0.3 mm within the engine assembly section. Additionally, the main frame ballast weight is documented at 614 kg for the L550 (456 serial number range).

Because heavy equipment maintenance involves high-pressure fluid and electrical hazards, always verify these reference values against your machine's exact serial number. Operating or repairing heavy machinery requires specialized technical training, so please ensure all procedures are handled by qualified personnel utilizing proper shop safety protocols.
