• 570 PDF pages in 26 files: engine, starting/charging, gauges, and diagram files, 182 pages; transmission, axle, and brake files, 130 pages; hydraulic, steering, and cylinder files, 114 pages; frame, mast, attachment, maintenance, and specification files, 144 pages.

Model and Section Coverage

The truck-specific material is centered on the XL and XL-EC families listed above. Selected mast, steering-axle, and differential sections also identify various H8.00-16.00XM (H170-360HD) applications, while the mast material includes an H360HD-EC configuration. This HD coverage is section-specific rather than uniform across the truck specifications, frame, maintenance, electrical/hydraulic, and transmission files.

P/N 899784 / 2200 SRM 2 identifies only the 20-page Alternator with Regulator section, not the full service-document set. Other numbered sections are Cooling System P/N 897934, Differential P/N 910072, Lift Cylinders P/N 910119, and Masts P/N 897386. The set also contains Metric and Inch (SAE) Fasteners P/N 910442, Starter P/N 910107, Steering Axle P/N 897108, and Tilt Cylinders P/N 910102.

Engine and Drivetrain Repair Depth

The included Perkins chapter covers Series 1000 models 1004-4, 1004-4T, 1006-6, and 1006-6T. It documents cylinder-head and valve-train repair, pistons and connecting rods, crankshaft and bearings, timing gears and camshaft work, cylinder liners, lubrication and cooling systems, turbocharger service, fuel-injection pump timing, injector testing, fuel-system bleeding, flywheel alignment checks, and WABCO or Bendix air-compressor drives.

Truck specifications identify the Perkins 1000-6 and a 6.0-liter GM V8. GM V8 material includes truck specifications, torque data, maintenance references, ignition-related information, cooling-system coverage, and electrical diagrams. A separate internal GM V8 engine-overhaul chapter is not part of this set.

Transmission documentation explains the torque converter, oil pump, control valve, hydraulic oil flow, and the forward, reverse, first-, second-, and third-speed clutch assemblies. Repair coverage includes removal, teardown, cleaning, inspection, reassembly, linkage adjustment, stall testing, pressure checks, and troubleshooting. The documented removal route varies by chassis size: H165-280XL units are serviced through the operator compartment, while H300-360XL units use the engine-compartment route.

Separate T-50 material covers installation in earlier chassis, related pressure references, and the Hyster T-50 hydraulic schematic for trucks manufactured after February 1993. Differential repair goes beyond basic component replacement, covering matched ring-and-pinion sets, pinion-depth shims, bearing preload, backlash, tooth-contact checks, rotating torque, pinion-carrier service, and final adjustment.

Hydraulic, Mast, Brake, and Attachment Systems

Hydraulic sections explain the tandem gear pump, priority valve, main control valve, tilt control valve, steering manifold, and the separate circuits used with and without load sensing. Empty-container units receive dedicated coverage for extend/retract and side-shift functions, two-speed hoist arrangements, lock-pin air and electrical circuits, bearing-block shimming, cylinder service, switch adjustment, and carriage alignment.

The mast material covers Vista two- and three-stage assemblies, carriage removal, lift chains, lowering control valves, lift cylinders, side-shift carriage components, wear-block adjustment, and mast installation. Frame procedures address the counterweight, fenders, hood, hydraulic and fuel tanks, radiator, operator compartment, cab, heater, windows, wipers, and engine or transmission removal.

Air-brake coverage includes the compressor, air tank, service and inching-brake pedal valves, parking-brake valve, air chambers, brake shoes and drums, quick-release valve, governor adjustment, brake-adjustment checks, and troubleshooting.

Schematics, Serial Breaks, and Service Cautions

Named diagrams include the air-system schematics with and without autoshift, H165-360 diesel wiring with autoshift and side-shift/fork-position functions, the GM V8 electrical schematic, the H330-360XL-EC empty-container attachment schematic, U.S. and EC hydraulic circuits with load-sensing variations, and the standard and T-50 transmission hydraulic schematics.

The diesel base electrical schematic identifies factory last-used/first-used breaks at D7E-2238/2239, E7D-1800/1801, E7E-1500/1501, C19E-1883/1884, D19D-1652/1653, and D19E-1500/1501. These references help separate earlier and later wiring before selecting a schematic or tracing a circuit.

The differential section warns that bearing caps must return to their original marked locations; mixing their positions can damage the carrier after reassembly. During transmission assembly, forced clutch alignment can damage the oil-sealing rings, and the manual specifically cautions against cutting, breaking, or unhooking the support sealing ring.

Because the covered work involves heavy counterweights, restrained mast sections, pressurized hydraulic circuits, air brakes, and major component lifting, review the applicable safety procedures before beginning repair.
