Together, these chapters make the manual useful for systematic troubleshooting as well as component-level repair. A technician can move from a symptom or diagnostic code to circuit checks, pressure or flow measurements, electrical schematics, adjustment values and the corresponding removal or installation procedure. Exploded views and illustrated procedures support mechanical work, while the diagnostic sheets provide decision paths for conditions such as engine starting failure, irregular running, exhaust smoke, lack of power, oil-pressure faults, overheating, steering problems and lift-system faults.

Engine, Injection and Measurement Work

The engine and injection sections are particularly detailed. The manual provides fuel-system layouts for both electronic and mechanical injection configurations, injector calibration information, pump data and PTO performance test sheets. It also explains pre-test checks for oil levels, filters, battery condition, radiator cleanliness, turbocharger pressure, hydraulic pressure and dynamometer setup so that measured performance can be compared under controlled conditions. Dynamic injection adjustment procedures show how timing is checked and corrected, while the injection-feed chapter covers filter replacement, system bleeding, injection pump service access, injector removal/installation and injector adjustments.

For internal engine work, the manual goes beyond basic maintenance. It contains dimensional drawings and limits for cylinder head and valves, cylinder block, liners and pistons, connecting rods, crankshaft and bearings, camshaft and distribution components. Removal and installation sequences cover major engine assemblies, including cylinder head service, liner protrusion measurement, piston and connecting-rod work, bearing and flywheel procedures, front and rear seals, distributor casing, balancer shafts, oil pump, water pump, thermostat, belt drive and turbocharger checks. Lubrication and cooling system diagrams help trace oil and coolant flow during diagnosis.

Transmission, Axle and Hydraulic Diagnosis

The drivetrain coverage addresses mechanical clutch systems, Revershift hydraulic-control PTO clutch arrangements, B41 gearboxes and their mechanical or hydraulic operating layouts. Procedures include clutch inspection, shaft service, control adjustment, input-housing work, reverser and doubler service, gear/range work and shimming. Rear- and front-axle chapters provide exploded views, torque and adjustment information, differential and crown-wheel procedures, wheel-hub and planetary work, bearing preload, backlash and wheel-alignment checks.

Hydraulic sections document circuit versions for tractors with and without Revershift transmission, including 48 l/min and 60 l/min specifications. They cover auxiliary distributors, brake valve adjustments, filtration, pump replacement and pressure/flow checking. Lift and hitch material includes mechanical and electronic control systems plus diagnostic paths for slow or absent lift, failure to lower and unstable or jerking operation. Steering coverage adds load-sensing components, priority-valve checks, pump-flow checks and fault-finding for heavy steering, vibration, oscillation and repeated path correction.

Electrical and Electronic Troubleshooting

Electrical coverage is organized around item lists, wiring references, functional schematics, harness routing and connector locations. The electronic-system chapters add engine-management component locations and sensor specifications, transmission management, TCE 9 electronic lift, instrument-panel functions and INFOTRAC. METADIAG is referenced within diagnostic procedures where electronic fault codes or operating data must be checked. This combination helps connect a mechanical symptom to the associated sensor, wiring path, control unit or hydraulic/mechanical subsystem rather than treating each system in isolation.

Workshop Capability and Instant PDF Access

The CLAAS Celtis 426 436 446 456 Diagnostic Manual 6005029688 (2005) PDF supports fault tracing, measurement, adjustment and major repair across the tractor’s engine, injection, clutch, gearbox, axle, brake, hydraulic, steering, electrical, electronic and cab systems. It is especially valuable when a repair depends on the correct sequence, pressure, clearance, torque, test condition or diagnostic path instead of trial-and-error replacement. Use the manual to plan work, confirm specifications, follow component removal and installation procedures, interpret schematics and diagnose system faults with the checks provided for the Celtis range.

Delivery is by instant PDF after purchase, with no physical shipping. The file can be opened on compatible phones, tablets and computers and pages can be printed when a workshop copy is convenient.
