1999 Mustang 2042 Skid Steer Loader Parts Catalog (P/N 008-12996)

• 150-page PDF of the Mustang 2042 OEM parts catalog, P/N 008-12996, issued December 1999 with March 2000 updates.
• T-bar, dual-lever foot-control, and dual-lever hand-control configurations are distinguished in the lift, tilt, and auxiliary control-cable selection chart.
• Axle drive, brake system, and neutral centering device breakdowns identify drivetrain components, mounting hardware, and steering linkage parts.
• Separate Hydro Pump (Gear Pump End) and Hydro Pump (Engine End) views show internal assemblies and overhaul seal-kit contents. Hydraulic motor listings distinguish two serial-dependent designs.
• Hydraulic coverage includes the control valve assembly, relief cartridges, spool locks, self-leveling valve, and lift and tilt cylinder repair kits.
• Yanmar 4TNE84 engine coverage extends to the cylinder block and head, crankshaft and piston assemblies, fuel injection pump, and governor.
• The Wiring Schematic – 2042 shows harness connections, starting and charging circuits, neutral switches, seat and seat-belt switches, and hydraulic valve lockouts.

This parts manual is suited to mechanics and experienced owners who can match exploded views and parts lists to the assemblies on their machine when planning a repair.

Systems and Component Breakdown

It starts with the main frame and lift arm configurations. The rear door, top door, and cabin panels have illustrated parts breakdowns, followed by ROPS/FOPS and seat-mounting components. Standard and suspension seats have separate lockout-switch and jumper-wire listings.

The lift-arm section identifies pivot pins, bushings, seals, and down-stop shims. A specific wear-plate note addresses visible twist between the Multi-Tach and lift arm when the wrong plate combination is used.

Plumbing layouts cover the hydrostatic, auxiliary, tilt, and lift circuits. Separate charge, cooler, and return-filter plumbing drawings identify the hose-and-tube assemblies and fittings connecting those systems. The valve pages break down the auxiliary detent, lift float, and tilt spool positioners, including components supplied only as part of an assembly.

Serial Breaks and Configuration Matching

The hydraulic motor pages pair machine serial applicability with the motor identification number:

These sections specifically call for the motor ID when ordering replacement parts, allowing the installed unit to be matched to its corresponding breakdown.

Fuel-door and top-door changes are listed at SJ99K000230, including the change from an extension-spring arrangement to gas-spring support for the top door. Revised brake mounting hardware is listed starting at SJ99J000223. These component-level distinctions matter when selecting parts for an earlier or later build.

Engine, Cooling, and Attachment Parts

The engine sections break down the lubrication system, gear housing, flywheel housing, and oil sump. Fuel-system coverage includes injection nozzles and lines, the feed pump, and the fuel filter and mount. Shim packs, gaskets, and seals are identified within their respective assemblies.

Cooling-system listings distinguish standard and heavy-duty radiators. Installation drawings also cover the oil cooler and engine mounts, while separate pages identify the muffler, air cleaner, and coolant-recovery bottle. Instrument-panel parts include gauges, switches, the control module, and timer relay; starting-motor and generator views extend to internal components.

Attachment coverage distinguishes single-pin Fast-A-Tach and two-pin mounting arrangements, including an adapter hitch between them. Bucket listings identify replacement cutting edges and teeth. Pallet forks, utility forks and grapples, guarded grapple buckets, a scarifier, and a three-point hitch adapter have their own parts coverage. Cab enclosure, windshield wiper and washer, heater, and sound-package components are also included.

Specification and Reference Data

Parts tables provide illustration references, quantities, part numbers, and descriptions. The numerical index cross-references part numbers to item numbers and printed pages. Assembly and kit listings identify included components, while engine drawings mark parts that are not sold separately.

Engine parts listings distinguish oversize piston and ring sets, undersize bearings, and alternative shims. These are component-selection details for repair planning.

This is an illustrated parts catalog. It does not provide step-by-step removal, overhaul, or adjustment procedures, troubleshooting charts, torque tables, or operating-clearance specifications. Those tasks require the applicable service documentation.

Always rely on standard shop safety practices and the applicable OEM instructions for raised lift arms and pressurized hydraulic systems before starting hands-on maintenance.
