CLAAS Celtis 426 436 446 456 Technical Support & Diagnostic Manual – 09.2007 PDF
The CLAAS Celtis 426 436 446 456 Technical Support & Diagnostic Manual – 09.2007 PDF is a wide-ranging technical reference for the Celtis tractor family. Its 887 PDF pages bring together engine support, B41 transmission information, axles, hydraulic systems, rear lift and steering, electrical services, instrument-panel and Metadiag diagnostics, cab and air-conditioning material, plus front-mounted equipment and pneumatic braking. The material is organised as a set of technical-support chapters rather than a short operator handbook, with system descriptions, schematics, dimensional data, checking procedures, adjustment values and fault-finding routines throughout.
Coverage shown in the manual includes Celtis 426, Celtis 436, Celtis 446 and Celtis 456. Engine material identifies 4045DRT76, 4045TRT77, 4045TRT78 and 4045 TRT 72 variants in the relevant procedures and dimensional data. The transmission section covers the B41 family and its mechanical-reverser, Revershift and Twinshift configurations, including 30 km/h and 40 km/h versions, slow-range arrangements and associated hydraulic/electronic controls.

Technical Depth and Diagnostic Content
This Celtis technical support manual is built around practical system understanding and test work. In the DPS engine chapter, the manual moves from inlet/exhaust construction and cooling/lubrication circuits into mechanical and electronic injection, component identification, sensor checks, pump operation and engine-management logic. Diagnostic sheets cover conditions such as engine failure to start, erratic running, grey or black smoke, white smoke, fuel-supply faults, lack of power, excessive oil consumption, abnormal oil pressure and cooling problems. Procedures include compression testing, valve-lift checks, turbocharger pressure checks, thermostat testing, sensor measurements and use of specified test equipment.
The engine data is detailed enough for inspection and repair decisions. Examples include cylinder-head and valve dimensional limits, oil-pump delivery and pressure figures, thermostat opening values, turbocharger checks, injector calibration values, piston/liner clearances, connecting-rod and crankshaft measurements, camshaft limits and viscous-fan checks. Electronic-injection material also explains DE 10 pump operation, the crankshaft-position and temperature sensors, pump-control solenoid, ECU inputs and outputs, pre-heating logic, idle automation, protection modes and SAE J1939 fault-code transmission.
Transmission coverage is similarly broad. The B41 chapter identifies gearbox variants, clutch arrangements, operating diagrams, torque settings and adjustment procedures. Revershift sections explain forward/reverse clutch operation, hydraulic pressure action, sensors, proportional solenoid valves, AUTO 5 control, calibration and fault logic. Twinshift material explains the hydraulic doubler, hare/tortoise states, pressure and ratio behaviour, electronic control and overspeed protection. Mechanical reverser, mechanical doubler, slow range, gear/range selection, synchronisers and control locking are also included.
Beyond the powertrain, the manual covers rear and front axle assemblies, PTO systems, oil-immersed brakes, steering geometry, differential operation and front/rear inter-axle preponderance. Hydraulic chapters document 48 and 60 l/min open-centre systems, Revershift and non-Revershift layouts, pump flow/pressure test points, steering circuits, mechanical and electronic rear-lift systems, TCE9 control, and auxiliary spool valves. Electrical Services adds fuse/relay information, conductor allocations, system-by-system wiring schematics, connector and harness tracking and electricity-tool references.
The diagnostic material continues through the instrument panel, Infotrac and the included Metadiag 2007 chapter. Metadiag coverage includes version updates, connections, engine and transmission applications, engine overview, fault history, error-code lists, DE 10 programming, transmission electrical tests, adjustments, programming and parameter setting. This gives the buyer both mechanical troubleshooting paths and electronic diagnostic context in one large reference.

Taken as a whole, the CLAAS Celtis 426 436 446 456 Technical Support & Diagnostic Manual – 09.2007 PDF gives a technician a connected view of the tractor rather than isolated repair snippets. Mechanical assemblies, hydraulic circuits and electrical controls are repeatedly tied to diagrams, measurement points, adjustment procedures and diagnostic logic, making the manual useful for tracing a symptom from system operation through testing and into the relevant repair or setting.
Workshop Procedures, Schematics and Measurements
The manual contains many visual references, including engine air, cooling and lubrication schematics; fuel-injection component drawings; gearbox cutaways and operating diagrams; rear- and front-axle layouts; hydraulic circuit diagrams; wiring schematics; connector layouts; sensor test diagrams; PTO and linkage drawings; and air-conditioning circuit information. Adjustment and measurement sections specify where and how to check pressures, flows, resistance, voltage, clearances, preload, torque and dimensional wear limits where applicable.
Examples of the workshop-oriented material include checking cylinder-head gasket failure symptoms, turbocharger shaft play and pressure, thermostat operation, engine oil pressure, fuel supply, compression, B41 shaft and bearing preload, clutch-pedal settings, Revershift calibration, hydraulic pump flow, lift-system operation and front PTO pressure. The manual also includes system protection and degraded-mode logic, which can help distinguish a mechanical fault from an electronically imposed limitation or stored diagnostic condition.
Get the Celtis Technical Reference Ready for the Job
Use the CLAAS Celtis 426 436 446 456 Technical Support & Diagnostic Manual – 09.2007 PDF when you need to diagnose engine or transmission faults, inspect hydraulic and electrical systems, check adjustment values, follow circuit diagrams, identify components, or prepare for mechanical repair work on the covered Celtis configurations. Having the procedures, specifications and test points together matters when a repair depends on the correct pressure, clearance, resistance, torque or operating sequence rather than guesswork. Your purchase is delivered as an instant PDF download with no shipping wait; open it on a phone, tablet or computer and print the pages you need for workshop use.
