2000–2012 John Deere 200CLC, 230CLC & 270CLC Excavator Repair Manual (P/N TM1931)

This John Deere technical manual, TM1931 (09JAN04), covers repair of the 2000–2012 200CLC, 230CLC, and 270CLC excavators. It documents component removal, disassembly, inspection, and reassembly, with model-specific procedures for the propel, swing, and hydraulic cylinder assemblies.

Text search and navigation: The PDF has searchable text and embedded bookmarks organized by repair topic and printed page number. Some labels within drawing images are outside the searchable text; small dimensions in the tool drawings benefit from zooming.

• Track system: Track roller, front idler, and carrier roller repair; track chain and master pin removal; sprocket, recoil spring, and track adjuster service.

• Propel and swing drives: Gearbox, motor, and park brake overhaul, rotary manifold air testing, swing bearing replacement, and component start-up procedures.

• Working equipment: Boom, arm, bucket, and linkage removal; pin and bushing inspection; pivot end-play adjustment; cylinder repacking and hydraulic bleeding.

• Main and pilot hydraulics: Main pump and drive gearbox repair, pump timing, regulator disassembly, multi-spool control valve rebuilding, and pilot controller service.

• Engine and auxiliary systems: Engine and starter removal, radiator and fan service, air intake leakage testing, fuel tank removal, and filter replacement.

• Cab and air conditioning: Cab and window replacement, seat belt service, R134a recovery, flushing, evacuation, charging, and heating/air conditioning component replacement.

Written for experienced technicians, the manual calls for hoists, presses, and dedicated service tools for the larger repair jobs.

Undercarriage, Propel, and Swing Repair

Teardown and rebuild instructions for track rollers, front idlers, and carrier rollers include metal face seal inspection and leakage tests. Track adjuster cylinder and recoil spring disassembly are also covered.

The 200CLC/230CLC propel motor is integral with the propel gearbox; the 270CLC has separate motor removal instructions. Exploded views distinguish their motor and park brake assemblies.

Swing gearbox repair has separate procedures for the 200CLC/230CLC and 270CLC. Swing motor and park brake inspection covers piston clearances and friction plate wear, with additional coverage of crossover relief and make-up valves and the 270CLC brake release valve.

Swing bearing work extends to upperstructure separation, bearing disassembly, and upper/lower seal replacement.

Hydraulic Pumps, Valves, and Cylinders

Pump repair covers front/rear shaft timing with the JDG1054 Aligning Bar, regulator feedback linkage, and the dampener drive (flex coupling). Separate exploded views identify the main pump/drive gearbox and the four-spool and five-spool control valve sections.

Pilot-system coverage extends to the pilot signal manifold and shuttle valves.

Cylinder differences: Boom, arm, and bucket cylinder repair separates the 230CLC designs from the 200CLC/270CLC assemblies. The 230CLC arm cylinder exploded view identifies its piston, plunger, and cushioning components, with rod inspection and seal installation details in the accompanying procedure.

The start-up procedures address pump and gearbox damage from running without oil. Cylinder instructions warn that compressed trapped air can damage cap seals and rings.

Engine Service and Serial-Number References

Engine coverage is removal and installation; internal engine overhaul is covered separately in CTM104.

Injection-pump instructions are cross-references: the 200CLC through S.N. 504000, plus the 230CLC and 270CLC, use the Bosch VP44 service reference in CTM170. The 200CLC from S.N. 504001 is directed to CTM331. This distinction helps select the correct fuel-system publication before injection-pump work.

TM1930 is the separate Operation and Tests volume. Electrical wiring diagrams and the referenced hydraulic pressure-test and pump-regulator adjustment procedures are not included in this PDF.

Structure, Cab, and R134a Service

Chassis frame repair includes structural welding precautions and counterweight removal. The air conditioning procedures distinguish oil-charge requirements for new, used, and internally flushed compressors, and cover the receiver-dryer, condenser, evaporator/heater assembly, and recovery/charging equipment.

Service Specifications and Dealer Fabricated Tools

Reference tables cover inch and metric fastener torques, flat face O-ring seal fittings, component clearances, wear limits, and fluid quantities.

Group 9900 provides dimensioned drawings for the ST4920 Track Recoil Spring Disassembly and Assembly Tool, its DFT1087 guard, and the DF1063 Lift Bracket used with DFT1130 Adapter. These drawings help a workshop prepare the fixtures specified for the repair.

Review the manual’s safety precautions and ensure hydraulic pressure is fully relieved before beginning any disassembly.
