What This Manual Enables You To Do

This Claas Celtis technical support manual gives you the complete factory procedures for maintaining, repairing and diagnosing the 426, 436, 446 and 456 tractors. Rather than a generic overview, it contains the actual torque values, adjustment shim calculations, pressure settings and diagnostic flowcharts that Claas technicians use in the workshop.

For engine work, you get the full DPS 4045 engine rebuild sequence — from cylinder head gasket replacement and valve clearance setting through to crankshaft grinding limits, liner protrusion checks and piston ring fitting. The injection chapters cover both the mechanical Stanadyne DB2/DB4 pumps and the electronic DE 10 pump, including static timing, dynamic adjustment with the Time Trac kit, and injector calibration pressures.

On the transmission side, the B41 gearbox chapter spans mechanical and hydraulic variants with torque settings for every casing joint and preload adjustment procedures for the input shafts, primary gear train, secondary shaft and reverser. The Revershift and Twinshift functions are covered down to solenoid valve pressures and electronic control unit pin allocations.

Hydraulic fault-finding is supported with flow and pressure test points for the 48 and 60 L/min circuits, steering unit pressure limiter adjustment (145/175 bar), and auxiliary spool valve pressure checks. The electrical chapter includes function-by-function wiring schematics, connector pinouts for the engine ECU, transmission ECU (Auto 5), instrument panel, and diagnostic socket, plus troubleshooting tables for starting, charging, lighting, PTO controls and Revershift clutches.

Front loader coverage includes both Propilot cable-operated and Flexpilot low-pressure hydraulic control systems, with supply pressure checks, internal leak calculations and electrical test values for the 3rd function, 4th function and Fast-Lock System solenoid valves.

Why This Manual Matters

Working on modern agricultural tractors without the correct specifications can lead to expensive mistakes — incorrect injection pump timing causing poor performance, wrong shim thicknesses causing bearing failure, or misadjusted hydraulic pressures damaging the transmission. This manual removes the guesswork by providing the exact figures Claas specifies.

The diagnostic tables are particularly valuable. Instead of replacing parts on suspicion, you can follow the step-by-step tests to isolate the fault — whether that’s a no-start condition on a DE 10 engine, erratic transmission operation on a Revershift tractor, or slow lift response on a TCE9 linkage.
