1979 International Cub Cadet 482 & 1100 Tractor Service & Repair Manual (P/N GSS-1485)

This International Harvester service manual covers the 1979 International Cub Cadet 482 and 1100 tractors. Publication GSS-1485, with Revision 1, dated November 1979, includes tractor repair procedures and service information for the IH equipment described below.

• Engine repair: Model-specific removal and installation, internal overhaul, cylinder honing, valve adjustment, and Synchro Balance inspection and reassembly.

• Fuel system: Carburetor and fuel-pump disassembly, float and inlet-valve inspection, mixture adjustment, and governor linkage settings.

• Electrical diagnosis: Starter overhaul and armature tests, ignition service, alternator output checks, diode and stator testing, and model-specific wiring diagrams.

• Drivetrain: Right-angle drive, transaxle and differential teardown, gear and bearing inspection, reassembly, and transaxle function testing.

• Steering and brakes: Cam-and-lever steering overhaul, front axle and wheel-bearing service, drive-belt and clutch-linkage work, and brake adjustment.

• IH equipment: Mower spindle and blade service, deck leveling, snow-thrower gearbox and auger-bearing work, and International 2 rotary tiller service.

The overhaul sections suit mechanics and experienced owners comfortable using micrometers, a dial indicator and electrical test equipment.

Engine Inspection and Reassembly

Internal engine coverage includes crankcase breather checks, oil-seal replacement, and wear inspection of the main bearings, piston, rings, connecting rod, crankshaft and camshaft. Cross-hatch pattern and valve-seat dimension illustrations support the cylinder-honing and valve-refacing instructions.

Synchro Balance procedures document counterweight timing during reassembly. The special-tool list identifies cylinder ridge reamer FES 467 and universal dial indicator FES 67-2.

Carburetor and Governor Adjustment

Fuel-system instructions distinguish worn needle valves, damaged inlet-valve seats and binding throttle shafts. Float positioning, fuel-pump component handling and warm-engine mixture adjustments accompany the governor and throttle-cable settings.

Starting, Charging and Ignition

The separate Model 482 and Model 1100 schematics include switch-contact tables, helping you follow the correct starting and PTO circuits for each tractor. Alternator illustrations explain rectification and the separate charging and lighting paths before the component tests.

Breaker-point replacement applies to early 1100 tractors. Later 1100 tractors and all 482 tractors use breakerless ignition, for which service is limited to armature and capsule-shield replacement.

The starter section warns that clamping the motor housing in a vise can crack its permanent magnets.

Transaxle, Steering and Electric PTO

Transaxle testing covers neutral operation, gear engagement, reverse operation and internal binding. Its reassembly checks address misplaced thrust washers, an omitted case gasket and incorrect differential through-bolt orientation.

Steering instructions cover bearing adjustment, cam-follower backlash and toe-in. The Front Axle exploded view identifies the pivot, knuckles and linkage, while brake adjustment relates pedal travel to clutch disengagement.

The Front PTO Clutch trouble-shooting chart addresses failure to engage and slow attachment operation. Separate clutch procedures distinguish the two tractor models and the replacement-clutch design that does not use shims.

For the 1100, the manual explains how a deep oil-seal-bore chamfer can leave the PTO field coil off-center, causing interference with the rotor.

Mowers, Snow Throwers and Rotary Tillers

Mower instructions distinguish early 1100 spindle-end bolts from the threaded-spindle and hex-nut arrangement on later 1100 and all 482 mowers. Main drive-belt adjustments separate 38/38A mowers from 38C and all 44/50 mowers.

Snow-thrower coverage includes chain and belt adjustment, runner settings and gearbox service. The rotary tiller section includes a rear-view tine-timing illustration and gearbox construction details; gear backlash is preset during manufacture.

Follow the manual's precautions for accidental starting, rotating PTO parts and supporting the tractor during service.

A Preview of Valve, Axle and Lubrication Data

These examples are a small selection of the manual's inspection and service data.

For the covered engines, cold valve-to-tappet clearance is 0.127–0.178 mm intake and 0.229–0.279 mm exhaust. The intake valve spring's specified free length is 45.2 mm (1.8 in.).

Chassis specifications list the front axle center pivot shaft diameter as 0.747–0.750 in. Transaxle installation specifies a refill of 2 liters (4 pints) of IH gear lubricant, SAE 90 oil.

PDF Search, Bookmarks and Page Count

Search and diagram detail: Text search is available in parts of the manual; some procedure pages and wiring labels lack searchable text. Bookmarks cover the contents and five main sections; an additional entry has no destination. Small wiring labels need zooming, and some Model 482 labels remain soft.
