This highly detailed, factory-issued PDF file is the complete Workshop Service and Repair Manual for the CLAAS Celtis series of utility and farming tractors. It comprehensively covers the entire range of this popular lineup, including the 426, 436, 446, and 456 models (which share much of their engineering with the Renault Celtis lineage). Unlike a standard operator’s manual, this critical document is designed strictly for professional agricultural technicians and advanced mechanics. It provides the exact factory specifications, torque values, step-by-step assembly/disassembly procedures, and crucial diagnostic routines required to keep these versatile machines operating reliably in the field.
The manual covers the following key topics in detail:
- General Information and Specifications: Crucial guidelines for safe agricultural machinery repair, including torque specifications for all hardware, proper fluid and lubricant capacities, and vital safety procedures for separating the tractor halves (splitting the tractor) for major repairs.
- Engine Systems: Complete diagnostic and repair procedures for the John Deere/DPS (Deere Power Systems) engines used in the Celtis lineup. This includes highly detailed instructions for servicing the fuel injection system, cooling system, and exhaust.
- Powertrain and Transmission: Extensive, step-by-step guides for troubleshooting, removing, and rebuilding the transmission systems (including the Twinshift or Revershift options, if equipped). It details the procedures required to maintain smooth shifting, service the clutches, and repair both the front and rear axle assemblies.
- Hydraulics, Brakes, and PTO: This critical section extensively covers the tractor’s power delivery systems. It details hydraulic fluid flow, provides specifications for pump pressure checks, and offers step-by-step instructions for servicing the steering hydraulics, the rear 3-point hitch lift mechanisms, the power braking system, and the Power Take-Off (PTO) driveline.
- Electrical Systems and Cab: Comprehensive electrical wiring schematic foldouts for the entire machine. It provides detailed troubleshooting guides for the instrument cluster, lighting, sensors, and the complete cab Heating, Ventilation, and Air Conditioning (HVAC) climate control systems.
Whether you need to overhaul the transmission on a Celtis 446, diagnose a hydraulic lift issue on a 426, or repair the HVAC system, this factory service manual is the definitive technical resource for maintaining your CLAAS Celtis tractor.
