Liebherr R944C HD-SL Litronic Parts Catalog – Type 1446 Serial 35846 PDF

Description

Liebherr R944C HD-SL Litronic Parts Catalog — Type 1446, Serial 35846

This is the complete illustrated spare parts catalog for the Liebherr R944C HD-SL Litronic hydraulic excavator built under machine type 1446, serial number 35846. It is the same catalog a parts desk works from when they need to identify, order or cross-check a component — exploded diagrams on one side, a numbered item table on the other, with the Liebherr article number, quantity, English description and the matching Portuguese designation printed side by side.

Undercarriage Assembly

The undercarriage section starts from the complete lower carriage and works outward. You get the track frame, the travel drive and tumbler wheel, the lubricated 500 mm track chain, track pads and pad screws, the floor plate nuts, the running roller and carrier roller installations, the guiding wheel installation, the chain guide and the track guide. Each roller and idler is shown both as an installed part and as a stripped sub-assembly with its own bushings, axle, lifetime seal, O-ring, dowel pin and screw plug — so a workshop can rebuild a seized roller rather than replace the whole unit.

Attachments, Boom and Stick

The front-end coverage includes the 6.45 m gooseneck boom, the 2.10 m stick and the HD backhoe bucket in the 1650 mm / 2.20 m³ configuration. The illustrations break down the boom and stick castings, the bucket linkage, pins, bushings, radial seals, half flanges, clamp collars, pressure lines and the piston rod cover for the bucket cylinder. The bucket itself is split into knife, adaptors, teeth, wearing caps, locking bolts, block parts and wearing plate sets so individual wear items can be ordered without a complete bucket.

Hydraulic Cylinders and Seals

Every major cylinder is shown as an assembly with a full parts breakdown: hoist cylinders (left and right), the bucket cylinder with its distributor block, and the stick cylinder. Each cylinder listing separates the barrel, piston rod, piston, piston rod bearing, radial seals, guide rings, supporting rings and seal kits, with the individual seal dimensions called out in the item description. That makes this section directly usable for reseal jobs without guessing which O-ring goes where.

Diesel Engine — D936 L A6

The engine chapter covers the Liebherr D936 L A6 190 kW diesel engine in remarkable depth for a parts catalog — eight catalogue pages of assembly groups plus a long list of dedicated sub-chapters. Coverage includes the basic engine, crankcase, crankshaft and gear, main and big-end bearings, pistons and rings, cylinder heads and covers, camshaft, rocker arms, tappets, push rods, oil pump, oil cooler, oil filter assembly, suction pump, injection pump, injectors and injection lines, fuel prefilter and fine filter, thermostat housing, water pump, turbocharger, exhaust manifold, starter, generator, flywheel and flywheel housing, plus the full seal kit breakdowns and engine sensors. Ancillary systems — aeration, crankcase breather, fuel lines, heating flange, coolant pipes — are catalogued separately.

Hydraulic Pumps, Motors and Valves

The hydraulic chapters cover the axial piston pump, the hydraulic double pump, the gear pump, the pump distribution gear, the travel drive FAT 400P073 with its brake and multi-disc set, the slewing drive SAT 325/254, and the axial piston motor used on the fan drive. Control valve coverage includes the main control block, travel pilot valve, stick bypass valve, pressure limiting valves, pressure reduction valves, shuttle valves, non-return valves, cold start valve, filter head and filter housing, plus the proportional distribution blocks and central lubrication blocks. Every one of these is broken down into gaskets, spools, springs, plug screws and seal kits.

Cab, Seat, Controls and Electrical

The operator environment is fully catalogued: cab structure and glass panes, front and lower windscreens, door frame, door lock, sliding window, wiper motor and arm, air conditioning unit, evaporator, water valve, heater, seat top and suspension, arm rests, joysticks and push-button covers, foot pilot valves, steering console, display and keyboard, and the complete electrical installation including wiring harnesses, relays, fuses, floodlights, batteries, battery master switch and antenna. The seat and suspension have their own repair-kit listings for the pneumatic spring, shock absorber, compressor and air hose.

Service Material, Lubricants and Tools

Beyond the machine itself, the catalog documents the Liebherr service material range with article numbers by pack size: hydraulic oils in 5 L, 20 L, 210 L and 1000 L formats, engine oils in 5W-30 and 10W-40 including low-ash versions, gear oils, axle oils, biodegradable hydraulic oil, greases, spray pastes, bit paste, antifreeze and AdBlue urea solution. The tool equipment chapter lists the complete onboard tool kit by DIN number, and a separate oil analysis set, hand pump, extraction valve and oil accident kit are catalogued as accessories.

Why this parts catalog earns its place in the workshop

Ordering the wrong part for a 40-tonne excavator is an expensive way to lose a day. This catalog removes that risk. Because the diagrams are exploded views with numbered balloons that map straight onto the item table, you can point at the exact component on the drawing, read the item number, confirm the quantity required and place the order without a second phone call. The Portuguese designations printed alongside the English descriptions also make it useful for mixed-language workshops and for cross-checking parts sourced through different channels.

It is equally useful away from the parts counter. When a hydraulic cylinder starts weeping, the seal kit listings tell you which rings are in the repair set. When a track roller needs rebuilding, the exploded view shows the bushings, axle, lifetime seal and dowel pins you will actually need. When a filter service comes due, the service material pages give the Liebherr article number for the correct oil grade and pack size. The diesel engine chapter alone covers enough assemblies — cylinder heads, pistons, bearings, injectors, injection pump, turbo, water pump, oil cooler — that major overhauls can be planned with the correct part numbers in hand instead of guesswork.

There is also real value in the cross-referencing. Where a component is superseded or a manufacturer’s number is entered in the list, the catalog prints it, so you can match the part against what is stamped on the component in front of you. Items marked as exchange parts, wear parts or wear parts critical for function are identified, which matters when deciding what to keep on the shelf as a spare.

Instant PDF delivery

The Liebherr R944C HD-SL parts catalog is delivered as a single PDF, available immediately after payment. No shipping, no waiting for a disc in the post, no risk of a lost paper copy. Open it on a laptop in the workshop, a tablet at the machine, or a phone on site — the file works on any device that reads PDF. Pages can be printed individually when you need a clean diagram on the bench, and multiple pages can be printed for a full teardown. Because it is a file rather than a bound book, it will not fall apart in a workshop environment and the pages you use most can be reprinted at will.

Whether you are a fleet owner keeping a machine running, an independent workshop taking on Liebherr work, or a parts specialist building a reference library, this 933-page catalog gives you the full exploded-view depth of a genuine Liebherr spare parts document for the R944C HD-SL Type 1446, serial 35846.
