O&K 1700 Parts Catalog – Factory OEM Parts Manual and Operating Instructions

If you’ve ever ordered a part for an O&K 1700 loader and gotten the wrong one because you didn’t have the serial number handy, you know the waste. Hours of downtime, freight charges both ways, and a machine that sits. This O&K 1700 Parts Catalog is the factory document that stops that. 207 pages of OEM exploded views, part numbers, and the exact operating instructions that Eaton issued in 1973 for Trojan machines serial 17-1011 and higher. No aftermarket guesswork.

Safety Precautions: Page 4 – Don’t Skip This

Page 4 lays out safety warnings specific to the 1700. Things like proper lifting points and hydraulic system depressurization. I’ve seen guys crack a line without reading the manual and get a face full of 200° oil. The manual tells you what to do before you touch anything. Follow it.

Capacities, Pressures, and Electrical System (Page 12)

Page 12 is where you find fluid capacities and system pressures for the 1700. Electrical system specs too – battery voltage, alternator output, and starter draw. If you’re chasing a no-start or a weak lift cycle, start there. The table gives you the numbers that match factory tolerance. Don’t trust a generic fluid chart for a loader that weighs 15 tons.

Filters and Breathers (Pages 20-21): Keep It Clean

Two pages on filters and breathers. Hydraulic oil filter, transmission filter, fuel filter – it’s all listed with the right part numbers and service intervals. Page 20 shows the filter element assembly for the hydraulic oil, part of the system that keeps your steering and bucket cylinders alive. Change them on schedule, not when the machine starts whining.

Torque Chart (Page 146) – Why You Need Factory Values

Page 146 is the torque chart. Not a generic chart from a hardware store – this one lists torque values for every bolted joint on the 1700: wheel nuts, axle bolts, transmission housing, control valve caps. I’ve had to re-torque heads that someone tightened by feel because they didn’t have this page. Leaks and broken bolts cost money. Use the factory number.

Battery and Wiring (Pages 78-79): Electrical Diagnostics

Pages 78 and 79 cover the battery and wiring harness. The Electrical system on these old loaders is simple, but a pinched wire or corroded ground can mimic a transmission problem. This section gives you the wiring diagram and battery location. If you’re troubleshooting intermittent electrical faults, having the OEM routing saves hours of tracing.

Who Needs This 207-Page Manual

Any owner or mechanic working on an O&K 1700 loader. The manual is written for experienced heavy equipment repair, not for a first-timer. If you’re a workshop operator with a 1700 in your fleet, this is the parts reference you hand to your lead tech so he can order the right parts on the first call. The manual also includes operating instructions (pages 14-15) and a full lubrication chart (pages 28-29) so you don’t miss a grease fitting. I’ve seen machines that got greased everywhere except the steering cylinder pivots because the guy didn’t have the chart. Don’t be that guy.

Source Authenticity: OEM vs. Aftermarket

This is the actual factory manual from Eaton’s Construction Equipment Division (Trojan). The cover says Manual No. TB071, Part No. 2022711, and it covers serial numbers 17-1011 and higher. Aftermarket parts catalogs reprint the drawings but often leave out the revision updates and the serial number application notes. The original OEM document has the note on page 3: “Always refer to the SERIAL NUMBER of your machine when ordering parts.” Without that note, you might order a part that doesn’t fit a machine built after a certain date. I trust factory paper because they don’t delete the fine print that saves your weekend.

Does this manual include operating instructions for the O&K 1700?

Yes, pages 14-15 cover start-up and shutdown procedures.

How do I locate the correct part using this catalog?

Find your machine serial number (stamped in the operator compartment). Then look up the assembly group (e.g., “Axle Assembly, Front” page 138) and cross-reference the exploded diagram with the part number list. The manual is arranged alphabetically by component name, then by engine variant (GM, CD, HD). If you have a GM engine, skip to pages 54-55. If you don’t have the serial number, you risk ordering a part from a different revision – the manual explicitly warns about that on page 3. Eaton’s parts numbering changed after serial 17-1011, so always verify.

Don’t waste another afternoon waiting on the wrong part. Access the Factory Manual and get the exact part numbers and torque values that keep your 1700 running.
