Liebherr PR 776 Parts Catalog Type 1296 Serial 19494 — 1048-Page Illustrated Spare Parts Manual PDF

Description

Liebherr PR 776 Parts Catalog — Type 1296, Machine Serial 19494

The Liebherr PR 776 crawler dozer runs on a fully illustrated spare-parts system, and this parts catalog for Type 1296, machine serial 19494, is the complete 1048-page reference built for it. Every assembly is itemised — position number, Liebherr part number, quantity and description — and each group sits with the component drawing needed to identify the correct part before an order leaves the desk. The catalog is bilingual: Russian and English appear together in the column headings and item lines, so the same page reads correctly for a Russian-speaking parts counter and an English-speaking workshop.

How the Catalog Is Built

The contents page lists the ten sub-groups beneath BASIC MACHINE with their group numbers, so an enquiry can be routed to the right chapter before a single drawing is opened. From there the catalog descends into individual assemblies, each with a position-numbered drawing and a matching item table. Part numbers are printed exactly as Liebherr issues them, quantities are given per assembly, and descriptions name the component rather than leaving it to the drawing alone. Group numbers such as 10 31 811 1, 11 08 250 1 or 12 80 784 4 appear at the head of each page, which makes it possible to quote a page and a position number over the phone and have the correct part pulled without ambiguity.

Where Liebherr splits a component by machine build, the catalog carries that split in the item table itself. Serial break markers appear against individual positions, so a roller, brake, cylinder or valve listing can be narrowed to the correct version for a given machine rather than guessed at from the drawing.

Basic Machine and Frame Group (00 10 000 00)

The base group covers the main frame and the structural hardware that ties the machine together. The frame assembly (12 81 086 0) is broken down with the cross member cpl. (12 81 087 7), clamping sleeves, bushings and the driver’s platform supports. The frame head assembly carries its own bushings, and the access ladder and left-hand ascent groups list their railings, antisclide coatings, fasteners and countersunk screws. Axle shell and cross member entries are itemised separately, which matters when a machine has been in service long enough for the structural bushes to need replacing.

Running Gear and Undercarriage (00 10 100 00)

This is the largest single block of the catalog and the one most buyers come for. The undercarriage assembly (10 31 811 1) and its left- and right-hand frame groups (10 31 811 3 and 10 31 821 7) list axles, sheets, tapered socket washers, spherical washers, axle shells, sealing rings, thrust washers, locking rings and dowel pins.

The filling fluids chapter (11 36 391 4) is the one that saves an argument at service time: filling quantities for the motor oil, PVG, grease, lifetime filling, hydraulic unit, cooling system, axle, drive unit, air conditioning and brake are catalogued as separate filling entries with their consumable part numbers, alongside the consumables themselves for hydraulic oil, gear oil, engine oil, low temperature grease and anticorrosion antifreeze. A separate axle filling, drive filling unit and brake filling entries make the book usable when only one circuit is being topped up.

Tool equipment (11 38 539 2) lists the tool wallet with its inserts and sockets, the hammer, pliers, screwdrivers, angle screwdrivers, ring spanners, open end spanners, double-headed spanners, cross handle, extension and socket for spanner, the lever-type hand grease gun with its rubber hose and mouth piece, the oil drain hose, the drain hose and the scavenging duct fat. A second tool equipment entry adds the combination of hand grease gun and key.

The ripper tooth cpl. (11 42 504 8) breaks down into the tooth itself, the tip, the armament and the tooth retaining element with its pin 31,75 and locking rings, and the cold-weather add-on parts group (11 36 403 1) supplies the pin extractor, console, weld plates, clamp halves, lid plates and hoses needed when the machine works in low temperatures.

Why This Catalog Belongs on the Parts Desk

Ordering a component for a crawler dozer without a parts catalog is guesswork, and guesswork on a machine of this size is expensive. A roller is not simply a roller: the PR 776 catalog distinguishes single-flange and double-flange D10N rollers, gives each its own axle, bushing, end piece and seal arrangement, and splits the listing by machine serial where Liebherr changed the design during production. The same discipline runs through the final drives, the hydraulic cylinders, the brakes, the fuel and oil filters, the cab glazing and the ripper. With this catalog open, a technician can quote the exact part number, confirm the quantity, check whether the repair kit is the better buy than the individual components, and hand the parts desk a page and position number instead of a description.

It is equally useful for planning. The service material chapter shows what a 500 h, 1000 h, 1500/2500 h and 2000 h service actually consumes, the filling fluids chapter lists what each circuit takes, and the tool equipment chapter shows which special tools the job calls for. For a workshop running a PR 776 as a working machine, that turns a maintenance stop from a series of surprises into a scheduled list.

Delivery is immediate. The catalog is supplied as a PDF that opens on a laptop, tablet or phone in the workshop office, on the shop floor or in the field, and any page or drawing can be printed for the mechanic doing the job. There is no shipping, no waiting for a paper copy, and no risk of a loose-leaf binder losing the page that matters. Download it once and the complete 1048-page Liebherr PR 776 Type 1296 parts catalog is on hand for as long as the machine is in service.
