Case 5550 1982 Parts Catalog – Factory Parts Numbers for the Drott Cruz-Crane

If you’ve ever stood in front of a machine with a broken part and no idea what number to order, you know the feeling. That’s why this 1982 Case 5550 Parts Catalog exists – 576 pages of factory-issued part numbers, exploded views, and revision updates. I’ve been turning wrenches for 28 years, and the difference between OEM part numbers and aftermarket guesses is the difference between a crane that works and a crane that sits. This catalog is the real deal.

What This Parts Catalog Actually Covers

Catalog number S406247 covers the Drott 5550 Cruz-Crane, including Revision 1 dated January 1982. The book is organized by machine sections – boom, hydraulics, swing mechanism, undercarriage, engine components, electrical, and more. Each section has exploded diagrams with item numbers keyed to the parts list. If you need the correct seal kit for the swing motor or the right bushing for the boom pivot, this is where you find it. No interpolation from a generic cross-reference chart.

Does It Include the Revision History?

Yes. The revision record log on page 5 lets you track which pages were updated. Revision 1 added pages like 135A, 135B, 369B, and replaced others. If your machine falls under a specific serial number range, those updates matter. The catalog even includes a cover sheet that tells you exactly which pages to insert and which to discard. That’s the kind of detail aftermarket reprints skip.

3 Reasons to Use OEM Part Numbers from This Catalog

1. Fit guarantee. Case engineers drew these numbers. A mismatched part on a 30,000-pound crane can kill someone. Not an exaggeration.
2. Revision tracking. Part numbers change – the catalog includes revision pages so you’re not ordering something that was superseded in 1984.
3. Time saved. I’ve seen guys spend an hour chasing a part number because they used a third-party list. This book cuts that to five minutes.

The Parts Catalog is not a service manual – it won’t tell you how to rebuild the engine. But if you need the exact part number for a hydraulic pump seal or a boom cylinder packing set, you’re in the right place. For the repair procedures themselves, you want the service manual. Check related titles like Case CX160B 2007 Parts Catalog – OEM Undercarriage Hydraulics or Case CX27B 2007 Parts Catalog – OEM Factory Specs for Mini Excavator if you’re working on newer equipment. For this 5550, the factory service manual is a separate document, but you need the parts catalog alongside it to get the right pieces.

How to Use the Parts Index Efficiently

The catalog uses a numerical index at the back – cross-reference any part number to find the figure and page. Start with the figure number from the exploded diagram, then locate the item number, then verify the part number. Don’t skip the revision flag column – a flag indicates the part was changed in Revision 1. If you order a pre-revision part, it might not fit. That’s a $500 mistake. The revision pages are inserted at specific locations – for example, pages 135A and 135B were added between 135 and 136. Pay attention to the page sequence printed on the cover sheet.

Parts Catalog vs. Service Manual: Know the Difference

Some people grab this thinking it will teach them to rebuild the torque converter. It won’t. A parts catalog lists the components – every nut, washer, seal, and hose – with their original part numbers. A service manual tells you the sequence, torque specs, and tolerances. You need both for a complete job. If you’re new to heavy equipment, start with the service manual for procedure, then order parts using this catalog. Case CX40B 2010 Parts Catalog – OEM Factory Spec Data is another example of a pure parts reference for later models.

For background on why OEM documentation matters in the equipment industry, see the Automotive Industry Overview on Wikipedia. The same principles apply – factory specs eliminate guesswork. Also check Automotive Industry Overview for a broader context on parts standardization.

FAQ

Is this the same as a service manual?

No. This is a parts catalog – it contains part numbers and exploded views, not repair procedures. You need the factory service manual for disassembly and torque specs.

Does it cover all 5550 variants?

This catalog covers the Drott 5550 Cruz-Crane with Revision 1. If your machine has a serial number outside the range listed in the revision cover sheet, some part numbers may differ. Check the revision record log on page 5.

How many pages?

576 pages. That includes the revision inserts, index, and full parts breakdown for every major system.

Can I get the actual part numbers from the PDF?

Yes. Every figure has a numbered list with the factory part number, description, and quantity per assembly. No aftermarket abbreviations – these are the numbers Case printed in 1982.

Stop wasting time with aftermarket part cross-references that don’t account for production changes.

Access the Factory Manual and keep it in your shop toolkit – right next to the service manual and the torque wrench.
