The New Holland L-781 L-783 L-785 Skid-Steer Loader Service Parts Catalog PDF is the illustrated parts reference for the L-781, L-783 and L-785 compact skid-steer loaders. Every assembly in the machine is broken down into exploded drawings keyed by reference number, with the corresponding part number, year/serial applicability, quantity and description listed on the facing page. If you are rebuilding, resealing, rewiring or simply trying to identify the correct replacement component for an L-781, L-783 or L-785, this catalog is the lookup tool that gets you to the right number the first time.

Read as a whole, the catalog functions as a complete teardown map of the L-781, L-783 and L-785. It starts at the frame and sheet metal, moves through the operator station and cab, then into the loader boom and every hydraulic circuit that drives it — bucket cylinder, boom cylinder, control valve, relief valve, flow control, self-leveling, auxiliary hydraulics and the hydraulic cooler. From there it works through the electrical system with point-to-point schematics, the instrument panel and lighting, and the charging and starting circuits. The second half is given over to the engine: the Deutz air-cooled unit in the L-781, and the Perkins 4.203.2 and Ford BSD 333 diesel engines in the L-783 and L-785, each broken down to block, head, valvetrain, pistons, crankshaft, injection pump, fuel lines, cooling system and air cleaner. The book finishes with the final drive chain cases and axles, the hydrostatic transmission and motor assemblies, the piston and gear pumps, control levers, servo, parking brake, hi-lo drive control and back-up alarm.

How the Parts Lists Are Organised

Every section follows the same two-page rhythm: an exploded illustration with balloon call-outs on one page, and a table on the next. Each table row gives you the reference number that matches the balloon on the drawing, the New Holland part number, the year or serial number the part applies to, the quantity required, and a description of the component.

Serial-number breaks are handled explicitly throughout. Where a part changed mid-production, the listing shows the break point so you can match the part to your machine rather than guessing. Examples include the seat sections, which are split at BSN 715137 and 712932, ASN 715138 and 728788, and 715992; the loader restraint electrical schematics, split at BSN 728845, BSN 728846, BSN 733332 and ASN 733333; and the parking brake, split at BSN 709976 and ASN 709977 on the L-781 and BSN 704646 and 704647 on the L-785 and L-783.

Where a component is supplied as a kit rather than individually, the catalog says so and lists the kit contents. Where a part was superseded, the newer number is shown with the replacement noted — for example the control valve assembly, the bucket cylinder assembly, the alternator assemblies and the starter assemblies all carry replacement references. Where a component is not serviced separately, that is stated plainly so you do not waste time hunting for a number that does not exist.

Threaded fasteners, washers, nuts, cotter pins and similar hardware appear in the listings alongside the assemblies they secure. A note at the front of the catalog explains that this common hardware is not illustrated and is not included with the service part or assembly when ordered as a replacement — it is listed so you know what size and grade to source.

Engines Covered by This Catalog

The engine sections are split by power plant, and the catalog makes clear which model used which engine. The Deutz F3L-912 direct-injection diesel attachments are listed for the L-781. The Perkins 4.203.2 diesel is covered for the L-783 and L-785, and the Ford BSD 333 / 33H diesel is covered for the same two models. Each engine section includes its own mounts, shrouding, exhaust, air cleaner, fuel lines, water trap and radiator listing so that parts stay correctly associated with the right machine.

Who This Catalog Is For

This is a working parts reference, not a repair procedure manual. It is the document you keep on the bench when you need to identify a component, confirm whether a part changed at a particular serial number, check how many of an item an assembly takes, or look up the correct number before ordering. Owners running older L-781, L-783 and L-785 machines will find it especially useful because so many of these loaders have been through multiple owners and partial repairs, and the serial-number breaks are the difference between ordering the right part and ordering one that will not fit.

Fault diagnosis of the electrical system is supported by the schematic sections, which show the loader restraint and non-restraint circuits, the warning lamp circuits, the charging circuit and the starting circuit for each engine variant. Hydraulic troubleshooting is supported by the circuit diagrams in the boom, control valve, auxiliary hydraulic, self-leveling and transmission sections, which show how the lines, tees, elbows, relief valves, check valves and solenoid valves are routed and connected.

Why the Correct Part Number Matters

Skid-steer loaders of this generation were built over a long production run and revised repeatedly. A seat frame, a parking brake linkage, a control valve, a cylinder head or a hydraulic line that fits an early L-781 will not necessarily fit a late one, and the same applies across the L-783 and L-785. Working from a generic listing or a guess based on appearance is how wrong parts get ordered and returned.

Using the exploded diagrams together with the year and serial number columns removes that guesswork. You match the balloon on the drawing to the reference number in the table, read across to the part number, confirm the serial applicability, and you are done. For assemblies that are supplied only as a kit or only as a complete unit, the catalog tells you before you start looking for individual pieces.

Get Instant Access

The New Holland L-781 L-783 L-785 Skid-Steer Loader Service Parts Catalog PDF gives you the full illustrated breakdown of the machine — frame and sheet metal, cab and doors, boom and attachment mounting, every hydraulic circuit from bucket cylinder through to the self-leveling kit, the complete electrical system with schematics, the Deutz, Perkins and Ford diesel engine sections, the final drive and chain cases, the hydrostatic transmission and motor assemblies, the piston and gear pumps, control levers, servo, parking brake, hi-lo drive control and back-up alarm.

Having the correct part numbers, quantities and serial break points on hand means you order once, fit once, and get the machine back to work instead of waiting on a second shipment. It also lets you price a job properly before you start, because you can see every component an assembly contains rather than discovering hidden parts halfway through a teardown.

This is a digital PDF delivered instantly after payment. There is no shipping, no waiting for a parcel, and no physical book to keep clean in a workshop. Open it on a laptop, tablet or phone at the machine, print the pages you need for the job, and dispose of them when they get oily. Because it is a PDF, you can jump straight to the section you need rather than flipping through hundreds of pages, and you can print the same page as many times as you like.
