O&K 6000 Parts Catalog – Factory OEM Manual (249 Pages)

Order the wrong part for an O&K 6000 and you’re not just out the cost of the part – you’re out the downtime waiting for the right one. I’ve seen guys slap on a hydraulic hose that looked right but was two inches too short, then wonder why the system pressure dropped. If you’re working on one of these machines and you don’t have the O&K 6000 Parts Catalog open, you’re flying blind. This is the OEM book – not some photocopied aftermarket reprint. It’s 249 pages of factory-issued part numbers, exploded views, and exact quantities per assembly.

Exploded Views: What You See on Page 1

Page 1 is the title page – O&K, Parts Manual TB078, Model 6000, Serial No. 78-1225 & Higher. That serial number range matters. If your machine is older, this catalog won’t match. Each exploded view in the book is drawn with the O&K part numbers right next to the callout lines. No guesswork about which bushing goes where. The diagrams are clear enough that a home garage guy can identify a seal or a bearing without calling the dealer every five minutes.

Serial Number Matching: Why Page 3 Is Critical

Page 3 of the catalog has a blank line for writing in your machine serial number. That’s not decoration – it’s a reminder to verify you’re looking at the correct edition. O&K changed components across production runs, and the catalog tells you exactly which serial numbers apply to each part group. If you’re rebuilding a final drive or replacing a swing motor pinion, cross-reference the serial number on page 3 before you order. Saves you the headache of a mis-match.

249 Pages of Factory Part Numbers

Two hundred forty-nine pages. That’s not filler. Each page covers a specific assembly: engine mount brackets, hydraulic tank, steering column, cab glass, electrical harness sections. Every part is listed with a seven-digit O&K number and the quantity needed per machine. Aftermarket part catalogs sometimes skip the quantity column, leaving you to guess whether you need one or four of a given bolt. This book doesn’t do that. It’s designed for a mechanic standing next to a parts counter with a grease-stained finger on the page.

Does This Catalog Include Torque Specs?

No. It’s a parts catalog, not a service manual. If you need torque values for head bolts or hydraulic fitting tensions, you want the O&K 6000 Service Repair Manual. The parts catalog gives you the exploded view and the correct part number; the service manual tells you how to put it together and what to tighten it to. Don’t mix the two up. I’ve seen guys try to rebuild a transmission using only the parts catalog, and they end up with a box of bearings and no installation sequence. Use the right book for the job.

OEM vs. Aftermarket: The Source Difference

This PDF is scanned from an original O&K print, not a third-party rewrite. The warranty language on page 2 (Eaton Corporation, TB078) is intact – that alone tells you it’s the real document. Aftermarket parts catalogs often re-draw diagrams and change part numbers to fit their own inventory systems. That’s fine if you like chasing cross-references. I don’t. Factory originals show you exactly what O&K intended. If you want to know whether a bolt is M16x1.5 or M16x2.0, the factory drawing won’t lie. An aftermarket version might not even show the thread pitch.

3 Ways This Catalog Saves You Money

First, you order exactly what you need – no returns, no restocking fees. Second, you avoid the dealer markup because you have the part number to shop around. Third, you don’t tear down an assembly only to find you’re missing a $3 snap ring that stops a gear from walking off a shaft. The catalog tells you that snap ring exists before you start. That’s time and cash in your pocket.

FAQs

Will this catalog work for an O&K 6000 with serial number 77-0000?

No. This edition starts at serial 78-1225. Earlier machines used different part numbers for many assemblies. You need the earlier catalog.

Does the catalog include wiring diagrams?

It includes electrical harness part numbers and routing diagrams for the harness itself, but not full schematics with wire colors and pinouts. For those, get the electrical parts supplement or the service manual.

How are the pages organized?

Grouped by major system: powertrain, hydraulics, electrical, cab, frame, and attachments. Each group starts with a general view, then breaks down into subassemblies. The index at the back lists every part number alphabetically by description, so you can find a “gasket, oil pan” without flipping through fifty pages.

Can I print this PDF and take it to the field?

Yes. The file is 249 pages, black-and-white diagrams. Print the sections you need or use a tablet. The resolution is high enough for the part numbers to be legible at 100% zoom.

You’ve got the machine. You’ve got the tools. Now get the right parts. Every time you open this catalog, you’re working from the same page as the factory mechanics who built the thing. Stop wasting money on wrong-fit parts and dealer runarounds. Access the Factory Manual and start identifying parts the way O&K intended.
