1994 Mustang 940 Loader Parts Catalog (P/N 000-34884)

This Mustang 940 parts catalog (Publication 000-34884, cover revised January 1994) identifies component numbers across early and late production configurations, with serial breaks in the individual parts lists.

The 160-page PDF is an English-language scan and includes pages updated in July and November 1994.

• Frame and lift arms: Chassis weldments, Fast-A-Tach mechanisms, R.O.P.S./F.O.P.S. components, and seat and seatbelt lockout parts.

• Drive and steering: Axle drive and brake assemblies, hydrostatic units, hydraulic motors, T-Stick and twin-lever controls, and neutral centering devices.

• Hydraulics: Double gear pumps, charge/cooler/return plumbing, lift and tilt circuits, auxiliary hydraulics, control valves, self-leveling valves, and cylinders.

• Yanmar engine: 4TN82E cylinder block, crankshaft, pistons, lubrication and cooling systems, fuel injection pump, governor, and engine controls.

• Electrical system: Wiring diagram, instrument panel parts, and component breakdowns for starting motors and the generator.

• Attachments and cab equipment: Pallet forks, utility forks, grapple buckets, scarifiers, cab heaters, and flasher lights.

Suited to mechanics and experienced owners who understand loader assemblies and need illustrated parts identification for repair planning.

Serial Breaks and Drivetrain Parts

The frame, brake, and axle-drive sections distinguish configurations around serial numbers 9405758/9405759. Hydrostatic Plumbing drawings separate the 9405759 through 1424997 configuration from machines starting at 1425008.

These component-specific listings help match hoses, linkages, and related hardware to the installed configuration before parts are ordered.

The Cluster Sprocket listings identify matched bearing sets that must not be interchanged. Replacement notes reference Service Bulletins 940-20 and 940-21 for cluster sprocket and idler arm updates; the bulletin procedures themselves are separate publications.

Pump, Valve, and Cylinder Identification

Double gear pump: The catalog distinguishes the old pump with raised ports and eight cover bolts from the later design with a flat surface and four cover bolts. Separate seal-kit listings and these identification details help avoid selecting seals for the wrong pump during repair planning.

Valves and cylinders: Main Relief Assembly and Self Level Valve section views identify internal parts and seals. The lift, tilt, and auxiliary control-valve sections have their own component lists, while lift and tilt cylinder drawings identify rods, barrels, glands, and repair kits.

Yanmar 4TN82E and Electrical Components

Engine block and piston listings distinguish standard components from oversize or undersize repair parts. Fuel injection and governor breakdowns cover the feed pump and control components, with governor changes identified by engine serial number 03800.

Starting motor breakdowns separate the version ending at serial 5466857 from the version starting at 5466867. Generator parts include brushes, the regulator, and the diode assembly.

The Wiring Diagram labels wire colors and connections for the starting circuit, neutral switches, air heater, warning lamps, and charging system. The instrument panel parts list identifies switches, gauges, harnesses, and jumper wires.

The decal section includes a specific warning that starting fluid can damage the engine.

Attachments and Reference Scope

Grapple bucket pages distinguish versions with and without cylinder guards. Additional breakdowns cover the adapter plate, 3-point hitch, cab doors and side windows, and windshield wiper and washer equipment.

Service-chart decals provide filter references, fluid-capacity data, and lubricant information. This is a parts identification reference, without step-by-step pump overhaul, cylinder repacking, engine repair, or fault-diagnosis procedures.

Always consult a certified technician before mechanical or structural service, particularly work involving raised lift arms or hydraulic pressure.

File Format and Readability

The total includes 148 regularly numbered pages, 10 lettered insert pages, one front cover, and one blank page. The inserts are 17A–17B, 23A–23B, 111A–111B, and 129A–129D; they are already included in the 160-page count.

Navigation: A printed table of contents and eight-page numerical parts index support manual lookup. The PDF has no embedded bookmarks or searchable text layer.

Diagram readability: Small component identifiers and wire-color labels in the main wiring diagram are legible when enlarged. Dense lettering on the service-chart decal is less clear.
