O&K 1500 1982 Parts Catalog – Factory Part Numbers, No Guessing

If you’ve ever ordered a replacement part for an O&K 1500 and got the wrong piece back, you know the drill: wait another week, pay return shipping, and still have a machine sidelined. That stops with the factory Parts Catalog from 1982. No aftermarket approximations. No “fits similar models” nonsense. This is the original 214-page manual Trojan Industries printed for dealers and shop foremen. Every illustration, every part number, every note about revisions comes straight from the OEM. I’ve used these books for thirty years – they save you from ordering a brake valve that doesn’t match your serial number. Automotive Industry Overview

What This 214-Page Parts Catalog Covers

Open the index and you’ll find every major system on the O&K 1500 loader. Wiring runs from the battery and alternator (pages 46-48) through the backup alarm, clutch cut-out switch, and main harness. The Brake section covers the brake control lines (pages 88-89E), parking brake assembly, brake valve (90-91), and axle brake group (100-101A). You also get the accelerator pedal linkage, air cleaner variants (GM and PO engines), automatic bucket leveler, hoist cut-out, axle cradle, bucket assembly, cushion valve, steering cylinder – the list runs deep. Each entry matches the exploded-view diagram on the facing page so you can point at the exact bolt, seal, or lever and get the OEM part number.

Why a Factory OEM Catalog Beats Aftermarket Copies

Aftermarket parts catalogs often omit revision notes, superseded part numbers, and the “N.S.S.” (Not Serviced Separately) markings that tell you a component only comes with the whole assembly. This factory catalog flags those limitations. It includes Revision 8 as of March 1982 and clearly marks pages where changes were made. When you call a parts counter, you read them the part number from this manual, not a third-party transcription that might drop a digit. The Parts Catalog also tells you exactly what information to include with your order: machine model number, serial number, part number, part name, quantity, and shipping address. Miss any of that and you’re asking for delays. Automotive Industry Overview

Brake and Wiring Sections: Factory Reference

Two areas where this catalog saves real time: the wiring diagrams and the brake groups. The main Wiring page (46-48) shows the battery, alternator, and backup alarm circuit with factory wire colors and connector part numbers. The Brake section lists the brake valve, control lines, and axle brake assembly – each with its own illustration. If you’re rebuilding the braking system, you need the part numbers for the O-rings, springs, and pistons inside the valve. Those are listed on page 90-91. Don’t guess. Use the factory spec.

How to Use This Catalog to Order Parts Correctly

First, find your machine’s serial number. This manual covers the O&K 1500 but remembers that component revisions depend on build date. The index references the basic system (e.g., “Axle Assembly” page 96-970, “Bucket Cylinder” page 56). Turn to that page, locate your part in the illustration, read the line item number, then match it with the part number in the table. Write down the part number exactly as printed – including dashes and leading zeros. Then call your supplier and read them that number plus the serial number. That’s how you get the correct piece the first time.

Who Should Own This Parts Catalog

Anyone who maintains an O&K 1500 loader: fleet mechanics, equipment dealers, and owner-operators. If you’re a home-garage enthusiast working on construction equipment, this catalog gives you the same info a dealership service writer uses. You don’t need to be a certified technician – the illustrations and index are straightforward. But you do need the OEM document if you want to avoid the parts-guessing game. O&K 1500 Parts Catalog

Does this catalog include part numbers for the brake assembly?

Yes. Pages 88-101 cover the brake control lines, valve, axle group, and parking brake. Each part has a factory number.

How do I use the index to find a part?

The front index lists every system alphabetically, from “Accelerator Pedal” to “Wiring.” Find your system, note the page range, turn to that illustration, and match the callout number with the parts list on the same page. The manual also includes notes like “AR” (As Required) and “N.S.S.” so you know if a part is sold separately or only as an assembly. Cross-reference with your serial number for revision accuracy.

You’ve got a loader that needs parts. Don’t gamble with aftermarket lists that skip revisions. Access the Factory Manual and get the same reference our shop uses when ordering O&K components. O&K 1500 Technical Manual
