Clark-hurth 45B Parts Catalog
If you’ve ever ordered a part for a Clark 45B using a third-party list and got the wrong bore size on a cylinder or a brake disc that didn’t fit the hub, you know the pain. That’s why I keep a factory parts catalog on the bench, not some aftermarket PDF that was OCR’d from a photocopy of a photocopy. This Clark-hurth 45B Parts Catalog is the real deal – 190 pages of OEM part numbers, original illustrations, and the exact indexing system the factory used. No guesswork, no cross-referencing six different sources.
Alphabetical Parts Index: Finding What You Need
Flip to any page and the organization is dead simple: everything from Accelerator Pedal to Windshield Wiper is listed alphabetically. Each parts group has its own letter prefix (A through V for standard equipment, Z for optional items) and a page number like lC12, lB18, or lG4. That’s not a typo – the page designations use a letter and number system. For example, the Boom Cylinder Assembly lives on page lB18. If you need the Air Cleaner Assembly, it’s lC6. The manual even includes a revision number after a hyphen so you know if the page was updated for design changes. No more guessing which version of a part your machine takes.
7 Parts Groups: What the Catalog Covers
This isn’t a service manual – it’s a parts catalog, so don’t expect torque specs or removal procedures. What you get is a complete breakdown of every component on the 45B wheel loader, organized into groups. You’ll find Axle Assemblies (front and rear, with differential carriers and planet carriers), Brake components (discs, pedals, valves, air dryer), Engine accessories (air cleaner, compressor, mounts), Electrical system (lights, wiring, battery, instruments), Hydraulics (boom and bucket cylinders, steering cylinder, Drott bucket attachments), and more. The converter and clutch assemblies are covered under group E. Every part number is listed with a description, quantity required, and often a reference to the illustration. If a part is not sold separately or not illustrated, the manual uses symbols (a dagger or section mark) to tell you straight up.
Does This Manual Cover the Complete Machine?
Short answer: yes, for the standard equipment level at publication date. The catalog includes everything from the Accelerator Pedal (lC12) to the Windshield Wiper (lI19). Optional and accessory items – like the Drott 4-in-1 bucket attachment, side dump bucket, alcohol injector, and backup alarm kit – are all in Group Z at the back of the book. You’ll also find decals, wiring clips, hose clamps, and even the cushion seat assembly. If your machine has a non-standard engine or a modified cab, you might need the serial number to confirm – and the manual tells you to always provide the serial number when ordering parts. That’s a factory requirement, not an aftermarket suggestion.
3 Reasons to Trust OEM Parts Catalogs Over Aftermarket
First, the part numbers are factory-verified. The catalog says: “To assure the best results and to maintain the original quality built into the machine it is important that only Clark-Approved Parts be used.” A third-party list might combine the 45B with a 45C, giving you a part that fits neither. Second, the illustrations are original line drawings, not blurry scans. You can actually read the callout numbers. Third, the indexing follows the factory’s own parts group logic. Once you learn it – letter prefix, page number, revision – you can find any part in under a minute. I’ve had techs waste an hour chasing a bucket tooth part number because they used a generic lookup. This catalog would have put them on page lG17 in ten seconds.
Get the Right Part Number the First Time
When you open this catalog, the first thing you see is a reminder: always give the machine serial number. Then check the alphabetical index. Say you need a brake disc – look up “Disc, Brake” and it points you to page lA6, under Axle Assembly, Front. Or if you need the entire bucket assembly, it’s on lB13 with a data sheet. The catalog uses abbreviations that make sense: assy for assembly, hyd for hydraulic, strg for steering. If a part has multiple versions (like a battery replacement kit for France – lF22), it’s listed separately. No ambiguity. And if a part is not illustrated, the manual marks it with a symbol so you know it’s a note-only item. That level of detail saves returns and downtime.
Torque Specs: Not in This Catalog but Still Critical
Let’s be clear: this is a parts catalog, not a service manual. If you need torque values for head bolts or converter charging pump nuts, you’ll want the factory service manual for the 45B. For that, check the CLARK 45B Parts Catalog – same machine, but the service book has the specs. For other Clark-hurth models, the Clark-hurth L320 1991 Parts Catalog – 690 Pages OEM Specs covers a different machine but follows the same part-numbering logic. And the Clark-hurth 85III 1965 Parts Catalog – Factory OEM Specs is another reference if you work on older loaders. But for the 45B, this catalog is what you need on the shelf next to your service manual.
Source Authenticity: Factory Original, Not a Reprint
This isn’t a copy of a copy. The PDF is a direct scan of the original Clark Equipment publication, Pub 3016. The page 2 introduction states “Clark-Approved Parts” and gives the full ordering procedure. The OCR excerpt in the file shows the same phrasing you’d see on a paper manual from the 1970s or 80s. There’s no aftermarket watermark, no missing pages, and the index matches the page numbers exactly. I’ve been burned by third-party catalogs that renumber pages to fit their formatting – that’s a nightmare when you’re on the phone with a parts counter. This one keeps the factory letter-number system. For more context on industrial machinery documentation, see the Automotive Industry Overview or Internal Combustion Engine – but for this loader, stick with the factory source.
- How do I find the part number for the boom cylinder?
- Look under “Cylinder Assembly, Boom” in the Alphabetical Index – that’s page lB18. The catalog lists the part number, description, and quantity.
- Does the catalog include optional attachments like the Drott bucket?
- Yes. Optional items are grouped under Group Z at the rear of the manual. The Drott 4-in-1 bucket attachment is on page lG12, with its own cylinder assembly on lH9.
- Can I use this catalog if my 45B has a serial number outside the range?
- The manual states that it covers standard equipment at publication date. If your machine has a later serial number, some parts may have changed. Always provide the serial number to your distributor – the catalog says that’s important.
- Is this a reprint or a scan?
- It’s a direct scan of the original factory publication – 190 pages, no reprints, no missing pages, original Clark part numbers and illustrations.
If you’re working on a Clark 45B wheel loader and you want to stop chasing wrong part numbers and wasting money on returns, get the factory source. Download the Factory Manual – it’s the same document that sits on every Clark dealer parts counter. No substitutes, no apologies.

Great factory service manual. The PDF is very clear. A must-have for any Clark-hurth 45B owner doing maintenance. Saves me a lot of time.
