2004–2011 John Deere 317 / 320 Skid Steer Loaders & CT322 Compact Track Loader Repair Manual (TM2152)

John Deere technical repair manual TM2152, dated 28APR11, covers the 2004–2011 317 and 320 skid steer loaders and CT322 compact track loader. The separate Operation and Test manual TM2151 is not included.

• Track system: Rubber track and sprocket removal, roller and idler rebuilding, idler leakage testing, track adjuster cylinder service, and recoil spring replacement.

• Axles and drive motors: Axle housing overhaul, drive chains and sprockets, and hydrostatic motor, park brake, and reduction gearbox repair.

• Pumps and steering controls: Hydrostatic pump inspection, hydraulic gear pump repair, centering plates, steering levers, dampeners, cross shaft linkages, and flywheel couplers.

• Loader hydraulics: Control valve overhaul, Quik-Tatch actuator replacement, boom and bucket cylinder removal, hydraulic cylinder bleeding, and self-level and counterbalance valve service.

• Engine and auxiliary systems: Engine and alternator removal, radiator and fan service, belt routing, speed control linkages, and external fuel supply components.

• Cab and HVAC: Operator enclosure, cab door, seat and seat belt service, plus air-conditioning flushing, purging, evacuation, charging, and component replacement.

Written for experienced technicians with the service knowledge and workshop equipment needed for the documented repairs.

Serial Breaks and Loader Hydraulics

Quik-Tatch coverage distinguishes hydraulic actuation through S/N 131876 from electric actuation beginning at S/N 131877. Pedal assemblies, hand control linkages, and loader control valves have separate procedures through S/N 150522 and from S/N 150523. These distinctions help match the machine's component layout to the correct repair instructions.

Standard hydraulic pump drawings distinguish the 317 from the 320/CT322. Optional high-flow pump coverage includes removal and drive-gear work; the pump has no serviceable internal components and is replaced as an assembly. Internal boom and bucket cylinder repairs are referred to separate component documentation.

Incomplete procedures: The early control-valve removal/installation section contains only pages 1–4 of 7. The general Quik-Tatch coupler removal/installation section contains only page 1 of 2.

Drive Assemblies and Undercarriage Repair

Single- and two-speed CT322 drive assemblies have separate teardown and reassembly sections. Metal face seal inspection, axle-bearing preload, and brake-disk wear checks support component inspection and reuse decisions.

Track Lug Measurement and Idler Oil Leakage Test Components illustrations accompany the track and seal checks. Axle Housing Assembly and Disk Valve Driver Alignment views show component arrangement and motor timing.

The manual cautions that removing the outer axle bearing destroys it. Its hydrostatic startup procedure also warns that prolonged low charge pressure can severely damage pumps and motors.

Pump assembly limitation: The hydrostatic-pump assembly procedure ends at page 7 of 8; its final page is missing.

Engine, Fuel System and Air Conditioning

Engine coverage concentrates on removal and installation. Internal PowerTech 4024/5030 repairs are referred to CTM301, and alternator/starter component service to CTM77; those manuals are separate. Fuel-system work includes the main and auxiliary tanks and fuel level sensor.

Fan Belt Routing illustrations distinguish machines with and without air conditioning. HVAC coverage includes compressor, receiver-dryer, condenser, and heater-unit replacement. The R134a refrigerant-oil information and recovery/recycling station installation sections each contain only their first of two pages.

Service Tools and Workshop References

General hardware charts cover inch and metric fasteners. Hydraulic connector tables distinguish O-ring boss, O-ring face seal, flare, cone-seat, and four-bolt flange connections.

Dealer-fabricated tool drawings include the DFT1101 cab/ROPS lift bracket, DFT1245 engine lifting bracket, and ST4920 recoil spring tool with DFT1087 guard. The ST4920 descriptive section contains only page 1 of 2, although separate dimension drawings are included.

Observe the manual's precautions for supporting raised components and releasing hydraulic pressure before service.

Track Wear and Axle Setup: Selected Values

These are a few of the wear and assembly specifications included in the manual.

For the CT322 undercarriage, minimum rubber track lug height is 5 mm (0.2 in.). Track roller plug torque is 21–26 N·m (16–19 lb-ft), while roller-to-frame cap screws are specified at 592–696 N·m (437–513 lb-ft).

For the wheeled loaders, the axle housing assembly procedure specifies axle-bearing rolling drag torque of 4.52–13.56 N·m (40–120 lb-in).

PDF Navigation and Page Breakdown

Text search and navigation: PDF text search is unavailable. Two bookmarks lead to the cover and foreword; there are no chapter bookmarks. Separate enlarged illustration pages accompany many component views.

One printable English PDF contains 415 pages: 410 service and reference pages, plus one cover, one contents page, one foreword page, and a two-page technical feedback form. All introductory pages, separate illustration sheets, and repeated pages are already included in that total.
