This is the Gehl Service Manual for the AWS36 and AWS46 all-wheel-steer loaders, form number 918265, covering machines built in 2008 with the Deutz F4M 2011 and BF4M 2011 diesel engines. Its 208 pages are organized by system: operation, maintenance, engine, power train, axles, brakes, steering, hydraulics and the electrical system.You get the specifications, fluids and lubricants, maintenance schedule and hardware torques up front, then component-level coverage of the F4M 2011/BF4M 2011 engine, the hydrostatic power train, the front and rear axles with differential lock, the four-wheel steering circuits, the work hydraulics and the electrical system with its relays and wiring. That lets you set valve clearances, service the differentials, diagnose steering and hydraulic faults, and trace electrical circuits on both models. The manual downloads as a searchable, printable PDF for the shop or the field.

Gehl AWS36, AWS46 Common Problems This Manual Covers
Engine shuts down with a warning alarm
Low engine oil pressure or high coolant temperature will sound an audible alarm and shut the loader down. The Engine chapter covers the F4M 2011/BF4M 2011 checks, including valve clearance and the cooling and fuel systems.
Manual Section: Engine p. 81Weak or slow hydraulic functions
Low hydraulic oil, an external leak, wrong oil viscosity or trapped air make the work hydraulics slow and weak. The Hydraulic System chapter gives the test reports, oil supply and control-valve details to diagnose it.
Manual Section: Hydraulic System p. 171Loss of drive power
A hydrostatic drive that lags or loses power often traces to the variable-displacement pump or motor and their test ports. The Power Train chapter covers these components for both AWS36 and AWS46.
Manual Section: Power Train p. 101Steering wanders or feels off
The four-wheel-steer system depends on the steering circuit and rams staying in adjustment. The Steering chapter gives the steering circuits and diagrams for both models so you can trace a fault.
Manual Section: Steering p. 157Electrical breaker trips or a circuit dies
A short or fault in a circuit trips a breaker or kills an accessory. The Electrical System chapter covers measuring methods, terminal descriptions, relays and the starter to find the cause.
Manual Section: Electrical System p. 183Axle or differential lock trouble
Bevel-gear shaft seals, differential cage screw connections and the differential lock all need correct assembly and torque. The Axles chapter covers the sealing service and differential-lock overview.
Manual Section: Axles p. 119Weak braking or a dragging parking brake
Poor stopping or a handbrake that drags points to the brake or inching-valve circuit. The Brakes chapter provides the brake, handbrake and inching-valve circuits and diagrams.
Manual Section: Brakes p. 151Frequently Asked Questions
Does this manual cover both the AWS36 and AWS46?
Yes. It is a single Service Manual, form 918265, that covers both the Gehl AWS36 and AWS46 all-wheel-steer loaders, including their model-specific pressures, fuse boxes and dimensions.
