Cub Cadet Manual Features & Selected Content Preview
The International Harvester parts catalog (P/N TC-113) covers International Cub Cadet 70 and 100 tractors, with IH and Kohler part numbers tied to assemblies, starter configurations, and production changes. It is an illustrated parts book rather than a procedural service manual.
PDF Search, Bookmarks and Page Count
Search and drawing detail: The catalog has searchable OCR text and bookmarks for the main component groups. Recognition errors can affect exact part-number searches; smaller electrical connection labels are best read at higher zoom.
One printable, English-language PDF contains 45 pages total: 43 catalog content pages, the catalog cover, and one additional page already included in that total.
Engine, Drivetrain and Lift Parts
The following selected contents highlight the main assemblies and parts-selection details. Other entries include the utility box and product graphics.
-
Kohler engines: Illustrated parts lists for K161, K181 service/replacement engines, and K241-A, including starter-specific components and automatic-compression-release variants.
-
Clutch and transmission: Exploded views of the clutch, gear-shift mechanism, differential and reduction housing, planetary creeper drive, and transmission-driven PTO.
-
Electrical equipment: Delco-Remy motor-generator parts, ignition and starting connections, battery arrangements, charge indicator, voltage regulator, safety starting switch, and lighting cable routing.
-
Hydraulic lift: Pump, cylinder, reservoir, spool valve, and control-linkage parts, with drive-shaft, idler-gear, pulley, and belt identification.
-
Steering, axles and brakes: Steering gear and tie-rod connections, front-axle pivot and knuckles, rear-axle carrier variants, brake discs, and linkage.
-
Chassis and attachments: Frame, hood, grille, fenders, seat, wheels, engine controls, instrument panel, implement lift handle, three-point hitch, and fixed drawbar.
-
Production changes: Serial-specific parts listings for transmission gears, battery hardware, steering components, governor parts, and control-cable retainers.
This catalog suits owners and mechanics who can match exploded-view reference numbers to parts lists and check the installed configuration before ordering repair parts.
Engine and Carburetor Identification
The engine sections distinguish parts used with and without automatic compression release, including camshafts and motor-generator drive pulleys. Flywheels, ignition components, bearing plates, piston oversizes, connecting rods, seals, and camshaft shims are identified in the engine-specific lists.
The K161 carburetor section identifies Carter 3738S, 3408S, and 3737S units. Carburetor listings also specify repair kit KH-25-757-01 and distinguish individually serviced components from pieces supplied only with an assembly or kit. Those notes help prevent ordering a small component that the catalog supplies only as part of a larger package.
Transmission Changes and Selective Parts
Gear selection: Tractors from Serial No. 65458 through 96765 use a 36-tooth second-speed gear and a 16T/26T second-and-third sliding gear. At Serial No. 96766, the listings change to a 33-tooth second-speed gear and a 19T/26T sliding gear.
The transmission case/differential/reduction-housing exploded view separates bearings, retainers, seals, and selective shims. Incorrect differential or countershaft shim selection can mislocate gears and damage bearings.
PTO components: The transmission-driven PTO breakdown identifies the shaft, bearing, oil seal, shifter clutch, lever, and rod. The transmission list also distinguishes the input shaft used on PTO-equipped tractors.
Starting Connections and Cable Routing
The electrical illustrations include the Delco-Remy motor-generator breakdown, pedestal rear view showing ignition and starting switches, voltage-regulator connection view, battery top views, and headlight/taillight cable-routing view. These are connection and component-location drawings rather than a conventional full-circuit wiring schematic.
Starting-system lists identify electric-start parts as Unit A and retractable-starter parts as Unit B. Model 100 battery entries split at Serial No. 70830, while battery-holder listings distinguish additional model-specific hardware at 74437. These distinctions support parts selection on tractors whose starting equipment may have been changed.
Hydraulic Lift, Steering and Axle Variants
The hydraulic illustrations identify the cylinder guide, piston and rod, backup washers, O-rings, pump body, and spool-valve components. Coverage is a parts breakdown; it does not provide hydraulic pressure specifications, pump tests, bleeding procedures, or adjustment sequences.
Steering and rear axle: The CCC-marked replacement steering assembly directs repair-parts lookup to Garden Tractor Model 1210. Rear-axle listings distinguish bushing-type and needle-bearing carriers; forcing the wrong bearing arrangement into a carrier can damage the bearing or carrier.
Front-wheel listings also include an alternative wheel assembly for 15 x 6.50-8 tires.
Parts-Ordering Notes and Service Limits
Common fasteners are frequently marked for local purchase, and some catalog entries are marked NLA. Other notes specify complete assemblies or repair kits instead of individual components.
The catalog does not provide step-by-step repair procedures, torque specifications, fluid capacities, service intervals, valve-adjustment data, or troubleshooting flowcharts. Its exploded views identify component relationships and hardware placement without replacing a factory repair procedure.
Work around the PTO, clutch, starting system, brakes, and hydraulic lift requires a secured machine and appropriate isolation of electrical and rotating components.
Selected Gear Tooth Counts and Hose Sizes
Drivetrain identification: The reduction-drive listing specifies an 84-tooth gear. The differential list identifies a 46-tooth drive gear and 10-tooth pinions, linking tooth counts to the illustrated components.
Hydraulic hose selection: Separate hose assemblies are listed at 9 inches and 14 inches. These are catalog dimensions for identifying parts, rather than hydraulic test or adjustment specifications.
