Clark-hurth 55C Parts Catalog

If you are wrenching on a Clark-hurth 55C wheel loader and you do not have the factory Parts Catalog in your toolbox, you are wasting time. I have torqued head bolts on more industrial engines than I care to count, and nothing kills a job faster than guessing which seal or bearing you need. This OEM manual is 164 pages of exact part numbers, exploded views, and indexing that lets you find the right piece the first time. No cross-reference guesswork. No third-party catalog that lists three possible sizes. You get the same book the dealer uses.

Let me walk you through what is inside and why this matters when you are under a machine with a deadline.

Engine Air Cleaner & Exhaust System – E13

Every Clark-hurth 55C owner knows that the air cleaner and exhaust system are critical for keeping the Engine alive in dusty conditions. The manual breaks down every clamp, gasket, and element. Page references are built into the alphabetical index at the front – you can jump straight to E13 for the full air cleaner and exhaust assemblies. The exploded view includes part numbers for the pre-cleaner, the canister, and the mounting bracket. If you are swapping out a cracked exhaust manifold, you will see the exact studs and gaskets needed. No chasing parts across three suppliers.

Transmission & Torque Converter Hydraulic System – I113

The Transmission section covers the hydraulic system that runs the torque converter and clutch packs. Most DIY guys skip the factory diagram and end up with leaks because they used the wrong O-ring. This catalog shows every seal, every check valve, and every solenoid connected to the transmission. Page I113 lists the hydraulic oil reservoir components, filter elements, and the converter housing gasket. If you are rebuilding the transmission, you need the exact part numbers for the clutch plates and piston seals – this manual has them. Do not rely on a generic parts book; the Clark-hurth spec is the only one that guarantees the fit.

Fuel Tank & Lines – F5

Fuel system problems on this loader are common when the tank pickup tube gets clogged or the lines chafe. The catalog at F5 gives you the Fuel tank assembly, including the sending unit, filler neck, and all lines from the tank to the injection pump. Each line is drawn with its exact length and bend radius. If you are replacing a rusted fuel line, you want the factory part number, not a universal hose that kinks. This section also covers the fuel gauge kit (index Z7) – the sending unit and gauge are listed separately so you do not buy a whole tank when only the sender is bad.

Axle Assembly, Front & Rear – A3/A5

Axles on the 55C take a beating. The front axle assembly is on page A3, the rear on A5. Each page shows the differential carrier, the planet carrier assemblies, and the brake heads. The differential carrier assembly – front drive (A7) and rear drive (A9) – includes every bearing, shim, and gear. If you are setting backlash, you want the factory part numbers for the pinion bearings and the crush sleeve. The planet carrier assembly section (A11) covers the sun gear, planet gears, and the ring gear. You will find the exact seal kits for the axle shafts. This is the level of detail that keeps a loader from leaking oil a month after you work on it.

Electrical System – E7,E9

Electrical gremlins are the worst. The catalog covers the Alternator (E9,E11,E19), the battery and battery mount (B1,E9), the horn (E7), the hourmeter (E5), and the instrument panel (E3,E5). Each wire harness is shown with its routing and the part numbers for connectors. The alternator mounting bracket and pulley are listed separately – if you snap a bolt, you know exactly which grade and length to order. The fuse block and relay locations are cross-referenced. No guessing whether that diode is part of the alternator or the main harness.

Original OEM Documentation – Not Aftermarket Reprints

Every page in this manual is scanned from an original Clark publication. The parts numbers have not been filtered through a third-party database that might have typos. The alphabetical index at the front (pages 1-164) includes abbreviations in English, French, and German – that is factory-level detail. There is no generic “R” or “L” ambiguity; the illustrations label every clip, bushing, and bracket. If you have ever been burned by a reprint that lost a page or had a blurred diagram, you understand why this matters. The Automotive Industry Overview may talk about standardization, but in practice, only the OEM catalog gives you the exact part numbers your machine was built with.

Who Needs This Parts Catalog?

If you own a 55C loader, work in a shop that services them, or buy used machines and want to verify parts before ordering, this catalog is essential. The DIY owner who tries to cross-reference parts online will end up with a box of wrong stuff. The professional mechanic who has this PDF on a tablet can find the part number while the machine is still in the work bay. Every section – from the bucket assembly (B18) and bucket teeth (B19) to the steering cylinder (C13) and boom cylinder (C9) – is organized so you do not waste an afternoon flipping pages. Check out the related Clark-hurth 35C, 55C, 45C Parts Catalog – Factory OEM Specs for additional models or the Clark-hurth 55C Parts Catalog – 238 Pages OEM Specs if you need a broader archive. For other Clark transmissions, see the Clark-hurth L320 1991 Parts Catalog – 690 Pages OEM Specs.

Can I use this parts catalog for a Clark-hurth 35C or 45C?

No. This is specific to the 55C model with serial numbers 55 CUMMINS – 4242B.

How do I find a part number if I only have a vague description?

Use the alphabetical index at the front of the manual. It lists every assembly – from “Axle Assembly” to “Bucket Teeth” – with the exact page where that part is illustrated. Every illustration includes callouts with part numbers. If you see a part in the index labeled “Engine Air Cleaner & Exhaust System E13,” you turn to E13 and find the complete exploded view. The index is thorough: it even has cross-references for synonyms like “Cylinder Assembly, Boom” and “Cylinder Assembly, Bucket.” Combine that with the abbreviation table at the start (pages 3-9) and you will locate any part within two minutes. That is faster than calling a dealer and waiting for them to pull a microfiche.

Access the Factory Manual now and keep this 164-page parts catalog on your tablet or printed out. It will save you the frustration of ordering a part that does not fit and the downtime of waiting for a return shipment. When you have the OEM part numbers in hand, you finish the job right.
