O&K RH4.6 2004 Parts Catalog

O&K RH4.6 2004 Parts Catalog – let me tell you why this thing matters on the bench. I’ve seen guys order three hydraulic hoses before getting the right one because they used an aftermarket parts diagram drawn by someone who never touched a wrench. This is the real deal: O&K factory print, 856 pages, published 2004. Every part number, every illustration, every note comes straight from the engineers who built the machine.

If you run a shop that works on excavators, or you own a RH4.6 and want to keep it running without parts delays, you need the right documentation. The table of contents shows exactly what you get: six languages – English, French, Italian, German, Spanish, Dutch, Portuguese, Danish. Most guys stick with the English section, but having the cross-reference in other languages helps when you’re dealing with international suppliers.

Ordering Rules and Part Number Index

Page 33 is the numerical index – that’s your gateway. Every part has a single-item number. The manual tells you the ordering rules on page 4 and instructions for ordering spare parts on page 3. Sound boring? It’s the difference between getting the right track roller and getting a box of mismatched bolts. The Conversione chart (inch-mm) on page 23 is your buddy – no more guessing thread sizes when you’re ordering from a metric catalog.

What Makes This Manual Different from Aftermarket Junk

Aftermarket parts catalogs often reprint old data, merge model years, or leave out revision notes. This O&K catalog is first edition April 2004, with all rights reserved by O&K. The disclaimer on page 2 even warns that O&K may update specs – meaning what you hold is the exact release from that date. No guesswork. If the part number in this manual doesn’t match your machine’s serial number, you know to call a dealer. That’s real troubleshooting, not internet forum advice.

7 Systems Covered – Working Sections

Maintenance parts section (pages 29-31) covers filters, seals, belts, and common wear items. The version list (pages 25-27) ties your machine’s identification to the correct illustrations. Whether you need to order a final drive seal or a control valve spool, the exploded diagrams show exact placement. Use the numeric index (page 33) to look up any part number from an existing old part – cross-reference it back to the illustration page. That’s how you avoid ordering the wrong pin and bushing kit.

Identification and Version List – Critical for Older Machines

Your RH4.6 might have had updates over the years. The version list on pages 25-27 breaks down which serial numbers correspond to which parts. I’ve seen techs order a brake assembly for a later model and waste a week because the mounting bracket changed. This manual saves that headache. Keep a copy in the shop office and one in the machine toolbox – the PDF is printable, but the searchable file is faster on a tablet.

Does This Manual Include Torque Specs?

Short answer: no. This is a parts catalog, not a service manual. You won’t find torque values for cylinder head bolts or injection pump settings. If you need those, you need the service manual for the RH4.6. But for ordering parts, this is the only source you should trust. The factory illustration lets you see exactly which fastener goes where – and the part number guarantees you get the correct grade and coating.

Who Should Buy This Manual

If you’re a home mechanic who bought a used excavator, you’ll save money by ordering parts yourself rather than paying dealer markup. If you run a shop, having a paper or PDF copy on hand speeds up quotes. Beginners: read the ordering rules on page 4 before you call a supplier. It tells you what information you need (serial number, model code, part number). That’s knowledge that keeps you from sounding like you don’t know what you’re doing.

What languages are in this manual?

Eight languages: English, French, Italian, German, Spanish, Dutch, Portuguese, Danish. English section starts page 3.

Can I use this to repair my RH4.6 engine?

No – this is a parts catalog only. It gives part numbers and ordering rules, not repair procedures. You need a separate service manual for torque specs and rebuild steps. That said, if you are replacing a part like a water pump, the exploded diagram shows you which gasket and bolts go with it, making assembly easier. The inch-mm conversion table (page 23) helps when ordering hardware from different suppliers.

Don’t waste time chasing part numbers on shady parts sites. Get the factory data from O&K direct. Access the Factory Manual and start ordering with confidence.
