1981 International Cub Cadet 582, 582 Special, 682, 782 and 982 Tractor Chassis & IH Equipment Service Manual (P/N GSS-1497)

International Harvester service publication GSS-1497 W/Revision 2, August 1981, covers the International Cub Cadet 582, 582 Special, 682, 782, and 982 tractor chassis and IH equipment.

Supplied as one 168-page PDF in English.

• 582 drivetrain: Clutch repair, tractor splitting and recoupling, reduction-drive overhaul, transmission and differential rebuilding, and creeper-drive service.

• 582 Special: Drive-belt and clutch-linkage service, right-angle-drive overhaul, transaxle disassembly and testing, and differential repair.

• Hydrostatic transmission: Check-valve diagnosis, charge-pump service, pump and motor overhaul, speed-control adjustment, and cam-bracket neutral-return checks.

• Hydraulic lift: Charge and implement pressure testing, relief-valve adjustment, lift-cylinder rebuilding, and single- and double-spool control-valve service.

• Steering and brakes: Steering-assembly overhaul, front axle and wheel-bearing inspection, and model-specific internal- and external-brake repair.

• PTO and electrical: Front PTO troubleshooting charts, clutch removal and adjustment, 982 rear PTO service, and model-specific wiring diagrams.

• IH implements: Mower spindle repair and deck leveling, snow-thrower gearbox and auger-bearing service, and rotary-tiller tine replacement and timing.

This manual is suited to mechanics experienced in drivetrain repair and equipped for tractor support, bearing work, and hydraulic pressure testing.

Engine Removal and Installation

Engine service covers removal and installation. Internal specifications and overhaul require separate publications: GSS-1498 for the 582/582 Special, GSS-1495 for the 682/782, and GSS-1484-1 for the 982. These engine manuals are not included.

Before tractor splitting, engine lifting, or work on pressurized hydrostatic systems, follow the manual's support, hoisting, and pressure-release precautions.

582 and 582 Special Drivetrain Repair

582 gear drive: Repair detail extends to countershaft gear and spacer arrangement, differential bearing preload, bevel-pinion backlash, and tooth-contact checks. Creeper Drive section views show the planetary assembly and shift mechanism.

582 Special: The transaxle chapter includes post-assembly checks for internal binding and correct gear operation. The right-angle-drive section warns that drilling into the input seal can damage the ball bearing beneath it.

Hydrostatic Transmission and Lift Hydraulics

Troubleshooting distinguishes loss of drive in one direction from slow or absent movement in both directions, helping narrow the checks before transmission teardown.

Internal repair covers the center section, cylinder blocks, piston slippers, valve plates, and swash plates, with an exploded hydrostatic-unit view. The manual warns that driving the swash-plate pins too far can puncture the housing.

Lift systems: Charge-pump relief specifications distinguish the 682 without hydraulic lift from lift-equipped 782/982 systems, with separate implement-relief settings for the latter two models. Cylinder resealing and control-valve service include air removal and leak checks.

The hydrostatic foldout referenced in the text is not included in this PDF.

Steering, Axles, and Brake Configurations

The 982 has separate steering and front-axle procedures. Rear axle and axle-housing service applies to all covered models except the 582 Special, which has its own transaxle section.

Brake coverage distinguishes the 582 internal brake, hydrostatic internal brakes on the 682/782, and external brakes on the 982 and 582 Special.

PTO Clutches and Wiring Diagrams

The Front PTO Clutch troubleshooting chart links symptoms to fuse, wiring, field-coil, belt, and attachment checks. Rear PTO Clutch and Hitch coverage adds 982 drive-shaft, bearing-housing, and pulley-hub service.

Electrical Schematics: The 582/582 Special uses a normally closed seat-switch circuit; the hydrostatic models use normally open circuits. Wire-color legends, key-switch contact tables, and optional 982 rear-PTO relay wiring support circuit tracing.

IH Mowers, Snow Throwers, and Rotary Tillers

38C, 44C, and 50C mowers: Center Spindle Assembly and Outer Spindle Assembly views accompany spindle inspection, blade sharpening, and belt adjustment.

QA 36A and QA 42A snow throwers: Attachment removal, lubrication, runner and chain adjustment, and gearbox repair are documented. Gearbox-pulley removal callouts identify two-jaw puller 17-473-3 and bearing puller 17-473-22.

Model 2 and 2B rotary tillers: Tine-orientation and timing drawings accompany replacement instructions and gearbox service. Gear backlash is factory-set, with no shimming adjustment.

Torque Tables, Wear Limits, and Test Data

Standard fastener torque tables, bolt-type identification charts, and metric conversion tables supplement component torques, including the steering-sector jam nut. Reference data cover clutch spring tests, hydrostatic wear limits, differential preload, gear backlash, and PTO electrical test values.

PDF Search and Page Condition

The total includes both covers, nine preliminary/reference pages, and 30 inserted 582 Special pages (2-20A1–2-20A28 and 2-84A1–2-84A2). Text search is partial, wiring labels are not searchable, and there are no embedded PDF bookmarks; small wiring labels require zooming. Printed page 2-45 has cropped hydrostatic theory text and an incomplete illustration.
