CASE 930 Diesel & 940 L.P. Gas Comfort King Parts Catalog A901 | 1966 Edition (P/N 8196701–8258382)

CASE Parts Catalog No. A901, issued January 1966, covers 930 Series Comfort King tractors in serial range 8196701–8258382. The model designations are 930 Diesel and 940 L.P. Gas.

The 163-page PDF is a scan of the factory parts catalog with an embedded OCR text layer and limited search reliability.

• Engine assemblies: Separate diesel and spark-ignition breakdowns for engine blocks, timing gear covers, cylinder heads, valve trains, pistons, connecting rods, and crankshafts.

• Fuel systems: Diesel injection pump, injector lines, and staged filtration; L.P. gas tank, fuel filter, carburetor, and regulator parts.

• Drivetrain and brakes: Hand- and foot-clutch assemblies, transmission gears, rear-axle chain drives, differential brakes, and PTO clutch components.

• Hydraulics and steering: Hydraulic control units, pump internals, remote cylinder, breakaway couplings, and separate Monroe and Ross power-steering assemblies.

• Electrical equipment: Diesel and L.P. gas wiring diagrams, distributor breakdowns, starter and generator parts, instrument panels, and lighting equipment.

• Cooling and air intake: Water pump, water manifold, thermostat, radiator shutters, and oil-bath air cleaners with pre-cleaner options.

Suited to mechanics and experienced owners who can match exploded-view callouts and application notes to the components fitted to their tractor.

Engine Assemblies and Parts Selection

The Pistons, Connecting Rods and Crankshaft breakdowns identify cylinder sleeves, piston rings, sleeve and piston sets, and standard or undersize bearing options. Valve-train listings distinguish stamped and forged rocker arms.

The diesel Camshaft and Oil Pump and Tachometer Drive sections specify compatible steel and cast gear combinations, including camshaft A33839 with pump gear A33840. These application notes help avoid ordering mismatched drive parts during engine repair.

Diesel Injection and L.P. Fuel Components

Diesel coverage includes the Bosch multi-plunger fuel pump, injector nozzle holders, individual cylinder injection tubes, and leak-off lines. Primary and final-stage fuel filters have separate parts listings.

The L.P. section breaks down the 4001AA regulator, including vaporizer, diaphragms, and valve components. Carburetor and regulator repair kits are listed with their component references.

Clutch, Transmission and PTO Variants

The Transmission Gear Train Assembly drawings show sliding gears, reduction shafts, bearings, and shims. Clutch listings distinguish hand- and foot-operated configurations and identify clutch adjusting tool O9342AB.

Gear-shift lever and bracket listings change at serial 8209971; differential gear listings distinguish tractors before 8222407 from those at that number and later.

PTO parts distinguish 540-rpm, six-spline and 1,000-rpm, 21-spline stub shafts, with corresponding drive gears and hydraulic-pump drive components.

Hydraulic Controls and Power Steering

The A23384 Hydraulic Pump breakdown includes control spools, pilot and main relief-valve components, cylinder-speed regulator, and lever-shaft seal kit.

Steering coverage separates A24933 Monroe and A24736 Ross cylinders, their mounting arrangements, and seal components. Front-axle listings distinguish straight- and tapered-spline spindles, while hydraulic control rods have separate 930 and 940 applications.

Wiring Diagrams and Ignition Parts

Electrical diagrams show component and harness arrangements with numbered references to the parts lists. Separate diesel and spark-ignition sections cover starting, charging, warning lamps, and instrument wiring.

Wico and Presto-Lite distributors have separate breakdowns. The catalog specifically warns against mixing their components within one ignition system.

Parts Reference and Repair Scope

Exploded-view references connect to part numbers, descriptions, and required quantities. Component dimensions and replacement notes support parts identification.

This catalog does not include step-by-step overhaul instructions, torque tables, fluid capacities, or diagnostic test procedures. Repair work on pressurized L.P. fuel, diesel injection, and hydraulic systems requires the appropriate service procedures and safety precautions.

File Format and Readability

The total includes 158 pages of parts listings and illustrations, plus one cover, one model and serial-identification page, one ordering-information page, and two alphabetical-index pages. Lettered continuation pages are already included in the catalog-page count.

Text search: OCR errors can prevent matches for component names and part numbers; drawing labels are poorly captured.

Navigation: A printed alphabetical index is included. The PDF has no bookmarks or numerical part-number index.

Drawing detail: Small electrical-diagram callouts generally need enlargement. Scan marks and uneven print affect some fine details.
