1988–1991 Hyster H165-360XL, H170-360HD, and H330-360XL-EC Forklift Service Manual Set, 1988–1991 (P/N 897386)

Use the chassis and maintenance sections to identify the truck configuration, then pair the component repair section with its pressure tables or schematics. The diesel wiring drawings distinguish the base harness from the Autoshift and side-shift/fork-position configurations.

Coverage limits: HD coverage is specific to the mast, steering axle, and differential sections, with HD-EC covered in the mast section. GM V8 coverage includes specifications, torque data, maintenance, cooling, and wiring. Internal engine overhaul is covered for the Perkins Series 1000. The T-50 material covers removal, installation, pressure checks, and a hydraulic schematic. For T-50 internal overhaul, the frame section directs technicians to the separate 1300 SRM 518 repair publication.

PDF Bookmarks and Wiring Detail

Finding sections and wire IDs: All files have embedded bookmarks. Text search works in most files, but the text encoding in Gauges and Electrical and Hydraulic Diagrams prevents normal word searches. Small pin numbers and wire codes in the wiring diagrams require zooming. A few wire IDs in the empty-container attachment drawing remain hard to distinguish at higher zoom.

The ZIP contains 570 pages across 26 printable PDFs, including nine original section covers and one notes page in Planetary Gear Axle.

Powertrain, Mast, and Circuit Service

This selection of service topics shows the work covered. The maintenance section also explains how to tow a disabled truck and check its wheel mounting.

• Perkins diesel repair: Cylinder head and valve train, pistons and liners, crankshaft bearings, timing gears, turbocharger service, and injector testing.
• Powershift and drive axle: Torque converter and clutch-pack teardown, control valve and oil pump repair, stall tests, and planetary wheel-end service.
• Hydraulics and steering: Tandem pump and priority-valve repair, steering relief checks, and service procedures for the main and tilt control valves.
• Mast and container attachment: Vista mast and carriage removal, lift and tilt cylinder overhaul, and empty-container attachment disassembly and adjustment.
• Air brakes: Compressor service, pedal and parking-brake valve repair, air chamber and brake drum work, and governor adjustment.
• Electrical diagnosis: Alternator output and regulator checks, Delco starter tests, gauge and sender troubleshooting, and wiring diagrams for diesel and GM V8 trucks.

The set suits trained lift truck technicians equipped for work such as lifting an engine and transmission assembly and testing hydraulic circuits under pressure.

Perkins Fuel Timing and Powershift Overhaul

The engine section covers injection pump timing, fuel-system bleeding, flywheel alignment, and service of the WABCO and Bendix compressor drives. It also identifies when the piston and ring design changed so replacement parts can be matched to the engine build.

The transmission removal route depends on the chassis. H165-280XL units use the operator compartment, while H300-360XL units use the engine compartment. The overhaul section calls out where forced clutch alignment can damage oil-sealing rings. Differential repair covers pinion-depth shims, bearing preload, and tooth-contact checks. The bearing caps have to go back in their original positions to preserve bore and thread alignment.

Mast, Attachment, and Chassis Service

The Vista section distinguishes two- and three-stage mast repairs and covers lift chains, lowering control valves, and side-shift carriage components. The empty-container attachment material explains extend/retract and side-shift operation, two-speed hoist arrangements, lock-pin air and electrical circuits, bearing-block shimming, switch adjustment, and carriage alignment.

Frame procedures cover the counterweight, tanks, radiator, operator compartment, cab, heater, windows, and wipers. Review the applicable safety procedures before working around a raised mast, lifting a counterweight, or opening hydraulic or air-brake circuits.

Diesel Harnesses and Hydraulic Schematics

The base diesel schematic marks the last truck serial number for the earlier wiring and the first for the revised wiring. That distinction matters when tracing circuits through the operator compartment and steering pod harnesses. Separate drawings cover GM V8 wiring, U.S. and European lighting, and load-sensing and non-load-sensing hydraulics. The T-50 hydraulic schematic is identified for trucks manufactured after February 1993.

A Look at Gear Clearances and T-50 Test Pressures

The differential section gives 0.25 mm (0.010 in.) as the initial ring-and-pinion clearance for a new gear set and allows 0.13 to 0.38 mm (0.005 to 0.015 in.) when adjusting tooth contact. With the original gear set, the reference is the clearance recorded during disassembly.

The T-50 pressure chart identifies torque-converter supply at port H as 827 to 1034 kPa (120 to 150 psi) and lubrication pressure at port G as 55 to 103 kPa (8 to 15 psi).
