65 PDF pages across 17 chapter files. The file count includes 17 repeated copyright pages and 12 duplicated chapter-transition pages, leaving 36 unique numbered manual pages: 2–9, 21–47, and 54.

Component and System Documentation

Front-chassis coverage is configuration-specific. The L175 and L225 use a fixed-tread axle; the L210 and L260 use the adjustable-tread design, with the L210 identified as basically similar to the L260. Procedures address axle pivots, spindles, hubs, drag links, tie rods, toe-in, and the recirculating ball-nut steering gear. The separate L225DT section follows the driven front end from the transmission-mounted transfer case through the drive shaft, differential, universal-joint axle shafts, spindle housings, king pins, hubs, and outer bevel drives. It includes complete axle removal, outer-drive repair, differential/bevel-gear service, and transfer-case overhaul.

Transmission chapters distinguish the four-speed sliding-gear/range units used on the L175, L225, L225DT, and L260 from the L210 three-speed/range unit. They document tractor splitting, transmission removal, shifter rails and forks, detents and interlock balls, input and output shafts, countershafts, reverse idlers, mesh-control shims, and reassembly checks. PTO coverage identifies the two-speed arrangements on the L175, L210, L225, and L225DT, the L260 four-speed PTO, and the L225/L225DT overrunning clutch. Clutch material covers pedal and release-lever adjustment, removal, pressure-plate and disc inspection, overhaul, linkage, release fork, and clutch-shaft service.

Rear-drivetrain sections cover differential removal and overhaul, main bevel-gear backlash, carrier-bearing preload, pinion position, tooth-contact checks, differential-lock variants, bull gears and bull pinions, axle shafts, bearings, seals, and brake adjustment/removal/overhaul. Fuel-system material separates renewable-element and spin-on filters, the L260 cam-driven piston transfer pump, and the gravity-feed systems on the other models. It covers bleeding, flywheel-mark injection timing, timing shims, pump removal and installation, governor linkage, injector fault isolation, nozzle testing, and nozzle-holder overhaul with suitable diesel test equipment. The injection pump is treated as a sealed unit; internal recalibration is outside the listed field-service work. Cooling chapters distinguish the L175/L210 thermo-siphon systems from the water-pump and thermostat systems on the L225/L225DT/L260. Electrical sections separate the L210/L260 generator system from the L175/L225/L225DT alternator system and include regulator tests, starter/solenoid repair, the L210 series glow-plug circuit versus parallel circuits on the other models, and the L175/L225/L225DT clutch-operated starter safety switch.

Specification Highlights

Condensed service data maps the Z750-A to the L175, Z1100A to the L210, D1100A to the L225/L225DT, and Z1300 to the L260. Dual U.S. Customary and metric tables cover tune-up and injection data, available hydraulic pressure and pump-delivery specifications, crankshaft/camshaft/piston dimensions, fluid capacities, lubricants, clearances, wear limits, and component torque specifications.

Selected illustrations include fixed- and adjustable-tread front axles, the recirculating ball-nut steering gear, L225DT front axle and transfer case, injection-pump/governor and injector assemblies, model-specific transmission gear trains and shifter mechanisms, and differential/final-drive/PTO layouts. Electrical coverage provides full tractor wiring diagrams for the L260 and L225/L225DT, plus an alternator/regulator schematic for the L175/L225/L225DT. A complete L175 or L210 tractor wiring diagram is not included.

Several repair traps are called out directly. Missing transmission interlock balls can allow two gears to engage at once. Mixing differential or output-shaft shim packs changes bevel-gear mesh and, on the L260, carrier-bearing preload. Overtightening an injector nozzle nut can distort the holder and make the nozzle valve stick.

The missing material corresponds to engine pages 10–20 and hydraulic-system pages 48–53. Only the opening engine-removal/cylinder-head material on page 9 and a final hydraulic fragment on page 54 are present. This set is not a complete internal-engine-overhaul or hydraulic-repair manual.

Tractor splitting, axle and final-drive removal, high-pressure injector testing, hydraulics, electrical work, and exposed PTO components require proper blocking and lifting equipment, pressure release, electrical isolation, and standard shop safety practices.
