PDF Search, Bookmarks and Page Count

Search and illustration limits: PDF text search is not available. Two embedded bookmarks provide entry points to the cover and foreword, without chapter-level navigation. The separate O-ring face seal fitting illustration is cut off at the right edge (PDF p. 61).

The manual is supplied as one printable 311-page PDF, including 40 separate illustration sheets and one duplicate A/C evacuation page.

Axle, Hydrostatic Drive and Loader Repair

These selected repair topics outline the contents rather than reproduce the full table of contents. Other examples include steering-lever-handle removal and park-brake solenoid-valve manifold replacement.

• Axles and chain drive: Axle-housing removal, bearing and seal service, preload shimming, rolling-drag checks, and drive-chain and sprocket removal and installation.

• Hydrostatic drive and park brakes: Step-by-step motor and brake disassembly and assembly for single-speed and two-speed configurations, plus hydrostatic-pump teardown, hub-coupler service, disk-valve timing, start-up and charge-pressure verification.

• Steering and control linkage: Steering-dampener inspection, lever and cross-shaft repair, pedal assemblies, and serial-specific hand-control linkage procedures.

• Engine and support systems: Engine removal and installation, alternator replacement, radiator, fan, guard, shroud and belt service, speed-control linkage, fuel tank and fuel-level sensor.

• Loader structure and cylinders: Quik-Tatch coupler service, upper and lower boom links, complete boom removal, boom-lock service, boom and bucket cylinder removal, and hydraulic-cylinder bleeding.

• Hydraulic pumps and valves: Standard-pump disassembly, wear inspection and assembly; high-flow pump and solenoid-valve service; early and late control valves, self-level valve, filter manifold and tank.

• Cab, structure and climate control: Cab, door, seat, seat-belt and rear-door procedures, structural-welding information, and R134a flushing, oil handling, recovery, evacuation, charging and component replacement.

John Deere states that the manual is written for an experienced technician; its use of presses, lifting fixtures, hydraulic gauges, refrigerant equipment, and other specified tools makes that the appropriate skill and shop-equipment level.

Repair-Volume Scope and Pump Limits

This is the repair half of the service information. Deere lists TM2191 for operational testing and fault diagnosis. Tracking and steering adjustments, hydraulic-control adjustments, and remote-start-box setup are among the Section 90 procedures referenced but not contained in this PDF. It also has no dedicated electrical or wiring-diagram section.

The engine section references the PowerTech 2.4 L and 3.0 L 4024/5030 family. Internal engine repair is covered separately in CTM301, while alternator and starting-motor component information is referred to CTM77.

Internal 120 Series hydraulic-cylinder work is directed to CTM114319 on the cover; the boom and bucket cylinder procedures also refer to TM-H120A. Deere identifies Operator’s Manual OMT205051 and Specifications Manual SP458 as companion publications. These additional manuals are not included.

The high-flow pump section describes drive-gear removal and installation. The pump itself has no serviceable internal components and is replaced as an assembly; this section does not provide an internal pump-overhaul procedure.

Serial-Specific Quik-Tatch and Control Valves

The Quik-Tatch chapters distinguish the hydraulic system through S.N. 131876 from the electric system beginning with S.N. 131877. Pedal assemblies, hand-control linkage and loader control valves have separate procedures through S.N. 150522 and from S.N. 150523.

Across the control-valve chapters, component views identify port-lock and spool-lock solenoids, the auxiliary-neutral switch, lift checks, system and circuit-relief valves, anticavitation valves, and pressure-release components. Separate valve teardowns help distinguish the correct parts and assembly information before repair begins.

Factory Views, Tooling and Service Data

Factory illustrations include Axle Housing Assembly, Bearing Pre-Load Measurement, Wheel Motor Assembly, Timing Disk Valve Driver, Control Valve and Pedal Assembly, and Boom and Auxiliary Spool Assemblies.

Named equipment includes the JT07042 charge-pressure gauge, JT02167A refrigerant identification instrument, JT02075 flusher and JDG1929 threaded driver. Dimensioned drawings and material lists support fabrication of the DFT1101 cab/ROPS lifting bracket and DFT1245 engine lifting bracket.

Reference data covers inch and metric fasteners; O-ring boss, 37-degree flare/30-degree cone, O-ring face seal, tapered-thread and four-bolt-flange fittings. Component sections supply inspection limits, wear criteria, fluid-capacity data, torques and adjustment specifications.

Assembly Cautions

The hydrostatic motor’s disk-valve retainer must face the specified direction; reversing it can let the driver slip and alter valve timing. After hydraulic-cylinder repair, trapped air can ignite assembly oil and damage cap seals and rings if the factory bleed procedure is not followed.

Raised-boom, suspended-engine or cab, pressurized-hydraulic, and R134a work requires the locks, supports, lifting equipment, pressure-relief precautions, and refrigerant service equipment specified by Deere.

A Preview of Park-Brake Inspection and Assembly Limits

For the park brake paired with the single-speed hydrostatic motor, the inspection table gives a minimum brake-disk thickness of 1.60 mm (0.063 in.) and a maximum flatness deviation of 0.20 mm (0.008 in.).

The two-speed motor’s park-brake section specifies a disk-pack height of 30.4–30.6 mm (1.197–1.205 in.), measured with the plates, disks and shims assembled on the bench before installation. The two configurations receive separate inspection and assembly information.
