Rexworks 5 to 8 Ton, 7 to 10 Ton 1973 Parts Catalog – Factory OEM Documentation

You’ve got a steel wheel roller from the early ’70s that needs a new steering valve or a water pump for the sprinkler system. The local supplier hands you a generic replacement and says “this should work.” Should work? That’s not good enough when you’re on a jobsite with a machine that weighs 10 tons. What you need is the Rexworks 5 to 8 Ton, 7 to 10 Ton 1973 Parts Catalog – the original factory document from Rexnord. I’ve been turning wrenches for 28 years, and I’ll tell you plain: if you don’t have the right part number, you’re wasting time and risking failure. This catalog gives you the exact breakdown of every component, from the instrument console to the brake assemblies inside the transmission gearcase. Forget aftermarket copies or scanned PDFs that lost resolution; you’re holding a clean 33-page original that lists every part number, quantity, and reference from the factory.

Rexworks 5 to 8 Ton, 7 to 10 Ton 1973 Parts Catalog: What You Get

This is Bulletin No. 467, effective serial number HR221 and up, dated March 1973. The table of contents runs through fourteen major systems. You get the Instrument Console, Control Deck, Power Unit (gas Ford 240 or diesel Ford 254), Hydraulics (lines, filter, tank, drive pump and motor from Sundstrand, steering pumps from Vickers or Webster, steering ram from Cross, steering valves from Gresen and Char-Lynn Orbitrol), Transmission with gearcase and brake, Drive Roll, Guide Roll with yoke and king pin, Frame with panel and hood, Sprinkler System (gravity feed, fog spray, water pump from Jabsco), Steering Wheel, and Lights/Horn. Every one of those sections includes exploded diagrams and part numbers.

Transmission Gearcase and Brake: Factory Part Breakdowns

The transmission section covers the gearcase and brake assembly together. If you need a brake band, a seal, or a gear cluster, this catalog gives you the Rexworks part number and the quantity required. I’ve seen mechanics order brake parts based on a generic cross-reference and end up with a drum that’s half an inch too small. Don’t be that guy. Use the factory listing. It’s on page 22 of the original print (the page numbers in the manual follow the sequence – page 1 cover, page 2 ordering instructions, then the 33-page body). Also, the Brake is listed explicitly in the Transmission – Gearcase, Brake line in the TOC. No guesswork.

Steering Valves: Gresen and Char-Lynn Orbitrol

Steering system parts are a common headache. This catalog covers two separate steering valve options: the Gresen valve and the Char-Lynn Orbitrol valve. Each has its own set of part numbers and seals. If your roller loses steering assist, you need to know which valve is installed. The catalog shows both configurations. The Steering Pump section also lists Vickers and Webster pumps, so you can match the pump to the valve. Ordering the wrong steering valve could cost you a day of downtime. Save that time by reading the part numbers directly from page 17.

Why You Need the Factory Part Numbers

Aftermarket parts catalogs for old construction equipment are often put together from photocopies of copies. Numbers get blurred, part references get lost. This is an original 1973 Rexnord publication. The part numbers are crisp: for example, the instrument cluster lists Stewart Warner gauges with specific model numbers (ammeter SW #440436, temperature gauge SW #442784). If you try to substitute a generic gauge, the mounting holes won’t line up. The catalog tells you exactly which part number to order. And the ordering instructions on page 2 are clear: always give the serial number, specify quantity by part number, and don’t order by sets or pairs. Follow that, and you get the right parts.

33 Pages of Original Rexworks Documentation

Thirty-three pages. That’s what you’re getting. Not a 500-page service manual that covers everything from the 1950s to today – this is focused on the 5 to 8 Ton and 7 to 10 Ton steel wheel roller with serial HR221 through a certain range. Every page is a factory-printed bulletin. You get the instrument console layout, the control deck (shown in the TOC as “CdntiO1 ‘Deck” – that’s the factory abbreviation), the sprinkler system with gravity feed and fog spray options, and the water pump from Jabsco. If you need the part number for a horn button or a starter switch (Cole Hersee #9216), it’s in there. I’ve used Rexworks catalogs on the shop floor for years. They’re built for speed: flip to the section you need, find the item number, cross it to the part number, and call your distributor. Rexworks SP-848B Parts Catalog – 182-Page OEM Manual covers a different machine, but for this roller, this is the one.

How to Order Parts Correctly

Don’t skim over the ordering instructions. Page 2 spells it out: specify quantity, part number, and name of part. Do not order by reference number or state quantity in sets or pairs. Give the serial number – it’s stamped on the manufacturer’s plate on the frame. Complete shipping address, billing info, and shipping method. A lot of old machinery gets scrapped because someone ordered the wrong part and didn’t catch it. With the factory catalog in your hand, you can verify the part number before you call. Also, pay attention to the serial number range. This catalog is effective from HR221 up – if your machine is older, you need a different bulletin. Rexworks SP400 1982 Parts Catalog – Factory Specs & Assembly Diagrams would cover the later models. Match the serial number.

That’s the difference between a fix and a half-assed repair.

Real-World Use: The Hydraulic Valve Question

You’re rebuilding the hydraulics. The drive pump is Sundstrand, the drive motor is Sundstrand, and the steering valves are either Gresen or Char-Lynn. The catalog shows the Steering Valve (Gresen) and Steering Valve Orbitrol (Char-Lynn) as separate sections. Each one lists the complete valve assembly and internal parts. If a spool or seal is worn, you can order the exact kit. The same goes for the steering ram from Cross – page 18 lists the ram assembly with part numbers for the rod, seals, and cylinder. Rexworks SP-600D Parts Catalog – OEM Factory Manual is another good reference for related models, but for your 5-10 ton roller, this 1973 parts catalog is the right document.

Does this parts catalog include repair instructions or torque specs?

No. It’s a parts catalog, not a service manual. You get part numbers, exploded diagrams, and quantities. For repair procedures, you need the separate service manual.

How do I use the part numbers in this catalog to order from a Rexworks distributor?

Look up the section for the system you need – say, the Transmission Gearcase and Brake. Find the item number in the diagram. Scan across to the Part Number column. Write down the exact part number (e.g., 298-06067-17 for the horn button). Also note the quantity required. Then call your Rexnord distributor, give them the serial number of your roller, and read them the part number. Do not order by the diagram reference number. The catalog tells you this on page 2. If you follow that, the distributor will pull the correct factory part. I’ve seen guys skip the serial number step and get a part for a later series that doesn’t fit. Always give the serial number. This catalog is serial-specific (HR221 and up), so if your machine is within that range, the parts match. If not, you need a different bulletin. Also, the catalog is organized by system – use the table of contents on page 3 to jump directly to the section you need. Automotive Industry Overview provides broader context, but for this specific machine, stick to the factory numbers.

Access the Factory Manual – you’ll have a clean PDF of all 33 pages, ready to print or view on your tablet. No blurred scans, no missing pages. Get the Rexworks part numbers you need to keep that roller rolling. Automotive Industry Overview
