John Deere Manual Features & Selected Content Preview
John Deere Technical Manual (P/N TM1497), revised 17JUL02, covers repair of the 300D, 310D, and 315D backhoe loaders, including non-powered front axles, MFWD configurations, and the 315D sideshift backhoe. This is the repair volume; Operation and Test Manual TM1496 is a separate publication.
PDF Access and Drawing Detail
Search, navigation, and small labels: PDF text search and embedded bookmarks are unavailable. Small labels in the fuse/relay layout require zooming. Many component drawings also appear as enlarged illustrations on separate pages, providing more usable detail than the small in-text thumbnails.
One printable, English-language PDF with 1,393 pages, including the cover, contents page, and two-page foreword.
Driveline, Hydraulic, and Backhoe Repair Coverage
The following selected repair topics show the scope of the manual. Other examples include torque-converter air testing and air-cleaner disassembly.
-
Axles and driveline: Wheel and tire service, drive shafts and U-joints, non-powered front axles, APL-735 and APL-2025 MFWD axles, rear axles, and planetary components.
-
Transmission and reverser: Transaxle removal, reverse-brake and forward-clutch repair, planetary assembly, transmission hydraulics, lubrication and charge pumps, and MFWD transfer-case overhaul.
-
Hydraulics and attachments: Hydraulic pumps, priority and system-relief valves, loader removal, loader/backhoe control valves, cylinder repair, boom and dipperstick structures, and sideshift locking components.
-
Steering and brakes: Tilt-column and steering-valve repair, standard-axle and MFWD steering cylinders, MFWD tracking adjustment, service-brake disks and pressure plates, brake-piston pressure tests, bleeding, and park-brake repair and adjustment.
-
Engine installation and auxiliaries: Engine removal and installation, coolant-heater and starting-aid service, fan-belt adjustment, radiator/oil-cooler removal, speed-control linkage repair, fuel-tank removal, and air-intake leak testing.
-
Electrical, cab, and HVAC: Connector repairs, switches, solenoids, instruments, lights, and alternator replacement; cab/ROPS, doors, windows, seats, heaters, blowers, and R12/R134a air-conditioning repair.
-
Factory reference data: Group-specific essential tools, service materials and parts kits, torque tables, capacities, wear tolerances, adjustment data, pressure specifications, exploded views, and component cross sections.
John Deere wrote this manual for experienced technicians, with essential tools identified for the applicable service work.
Engine Access and Component-Manual Limits
Engine coverage follows the machine connections and removal/installation work. The specifications identify the 4039D in the 300D, either the 4039D or 4039T in the 310D, and the 4039T in the 315D.
Additional internal engine information requires CTM8. The electrical sections also refer to CTM11 for engine accessories and CTM77 for complete starter-motor repair; these publications are separate from this PDF.
Axle, Transmission, and Brake Build Differences
The serial-specific chapters help a shop match repair procedures and replacement components to the machine's build. MFWD axle coverage changes from APL-735 through S/N 796033 to APL-2025 from S/N 796034; reverser solenoid and directional/regulator-valve procedures change at S/N 792483, and brake-disk/pressure-plate procedures at S/N 796852.
MFWD axle instructions cover constant-velocity joints, differential and pinion overhaul, bearing and shim setup, backlash, tooth-contact checks, and cone-point adjustment. Transmission procedures extend to shifter shafts and forks, the differential lock, and serial-specific control valves.
The brake instructions warn that fitting the wrong serial-specific disk can cause premature wear and damage the transaxle case.
Hydraulic Pumps, Control Valves, and Backhoe Structures
Through S/N 802199, pump repair covers the multi-section arrangement and separate priority valve. From S/N 802200, the manual distinguishes main and auxiliary pumps and places the priority section in the loader valve.
Step-by-step procedures address control-valve disassembly, relief and anti-cavitation valve service, cylinder resealing, attachment-linkage adjustment, bucket cutting edges and tooth shanks, and swing-frame repair. Relief-valve testing and adjustment procedures are referenced to TM1496.
Extendible-dipperstick procedures divide at S/N 787833/787834. The early collar-adjustment section warns that overtightening can wear the bearing strips or bind the extension. The 315D sections cover the sideshift frame, locking valve, pistons, and bushings.
Connector Work and Refrigerant-Specific Service
Electrical instructions cover DEUTSCH and WEATHER PACK contact work and conversion from SURE-SEAL to WEATHER PACK connectors. HVAC chapters separate R12 and R134a compressor repair, clutch inspection, leak testing, and component oil-charge data. Factory-installed R12 systems are identified through S/N 790701.
Illustrations and Workshop Equipment
Illustrations include the APL-2025 knuckle/planetary-hub exploded view and MFWD transfer-case cross section. Steering-valve and bucket-curl/boom-raise relief-valve sections show internal parts; the main-pump exploded view and model-specific boom, crowd, stabilizer, and swing-cylinder sections support component repair.
Named equipment includes the JDG593 measuring ring, JDG74 cone-point adjustment set, JDG734 spool-valve seal installer, and JDG894 RIVNUT installation tool. Dealer-fabricated tool drawings include the JT38000 differential lifting tool and DFT1101 cab/ROPS lift bracket.
Hydraulic and heavy-component work requires pressure relief, mechanical support for raised structures, clean service practices, and lifting equipment suitable for the assembly.
A Preview of Axle Backlash and Compressor Clearances
For the APL-735 MFWD differential through S/N 796033, the ring-gear backlash specification is 0.13–0.18 mm. For the APL-2025 from S/N 796034, it is 0.07–0.22 mm; these values accompany the axle setup and inspection instructions.
The HVAC specifications distinguish compressor hub-to-pulley clearance by refrigerant system: 0.35–0.65 mm for R134a and 0.53–0.91 mm for R12.
