O&K 1700 Z 1989 Parts Catalog – Factory OEM Parts Identification for the 1700Z Loader

You’re standing in the parts room with a loader that won’t move. The part you pulled is wrong. The counter guy shrugs. Sound familiar? That’s the exact reason this O&K 1700 Z 1989 Parts Catalog exists – to put the correct part number in your hand the first time. 286 pages of factory-sourced part numbers, group indexing, and ordering instructions. No guesswork, no third-party reprints. This is the same binder that came with the machine from O&K Trojan Inc. in July 1989.

If you’ve ever ordered a “hydraulic filter” and gotten something that doesn’t fit, you understand the pain. This manual eliminates that. Every assembly – engine, transmission, axles, hydraulics – is broken down by a group number system explained right in the introduction. Flip to the index, find the group, turn to the page. The part number and name are listed. Period.

Your serial number matters. T21-1501 and higher. Miss it and you risk ordering a part that changed mid-production.

Group Number System: How It Finds the Exact Part

O&K organized everything by group numbers – the first two digits tell you the system (32 = Hydraulic System, for instance), the next two narrow it to the assembly, and the last two pin down the specific component. Example from the manual: Group 32 05 01 means Hydraulic System, Hydraulic Tank Assembly, Hydraulic Filter. That’s not guesswork – it’s a consistent factory coding. The index at the front of the catalog gets you to the right illustration, and the illustration has item numbers tied to the parts list. Use it once and you’ll never waste time digging through bins again.

Serial Number Requirement – Why You Cannot Skip It

O&K made running changes to the 1700Z. The manual says clearly on page 2: “S/N T21-1501 & HIGHER.” If your machine is below that range, this catalog doesn’t cover it. Even within the covered range, certain components might have been updated. The introduction tells you to include machine model number, serial number, part number, part name, and quantity with every order. Sounds like a lot? It beats getting the wrong part twice. Working with O&K parts means respecting that serial number. Write it down on the line they provide inside the front cover.

What This Parts Catalog Covers: Engine, Transmission, Axles, and More

The manual doesn’t stop at the engine block. It covers the entire O&K 1700Z loader: front and rear axles, transmission, hydraulic system, steering, electrical, frame, and attachments. Each assembly has its own group number range. The engine itself is grouped – you’ll find cylinder head, oil pan, fuel system components all listed with OEM part numbers. No generic cross-references. O&K spec part numbers only. If you’re rebuilding the transmission, you need this catalog to order the correct seal kit, clutch plate, or gear. O&K 1700 Z Parts Catalog is the foundation for any repair job – but you’ll also need the service manual for torque specs and procedures. For other O&K loaders, see the O&K L45, 4500Z 1990 Parts Catalog – Parts Manual TB126 or the O&K L3000 Parts Catalog – Factory OEM Manual (236 Pages).

Ordering Parts the Right Way – What the Manual Demands

Read the intro carefully: “Use only parts which are authorized by O&K Trojan Industries, Inc. to ensure that original dependability and performance will be maintained.” They mean it. The catalog is designed so you give them the exact part number and name. No ambiguous descriptions like “loader arm bushing.” You’ll see the official OEM item number and the correct name. The group number even tells the parts department which drawing you’re referencing. For techs who hate returns, this is money saved.

Why OEM Documentation Beats Aftermarket Parts Lists

Aftermarket catalogs often combine multiple years, omit superseded parts, or use generic numbering. This OEM manual is specific to the 1700Z model, serial range T21-1501 and up, printed in 1989 by O&K Trojan. The group number system is unique to O&K. Third-party data won’t have that. If you’re maintaining an older loader for a fleet or a personal machine, this factory document keeps you in spec. For context on how OEM documentation fits into the broader Automotive Industry Overview – though this is off-highway equipment – the same principle applies: original data prevents misdiagnosis and misordering. Automotive Industry Overview confirms that factory specifications are the only reliable source for mechanical systems.

Technical Specifications & Document Authenticity

Manual TB133, part number 4619408. 286 pages. Published July 1989. Covers O&K 1700Z Loader with serial numbers T21-1501 and higher. The scanned PDF is a direct copy of the original paper manual – no missing pages, no OCR errors on part numbers. You get the group index, all illustrations, and the parts lists. We have the largest collection of OEM shop manuals in North America, and this one checks every box for authenticity.

Does this parts catalog include torque specifications or repair instructions?

No. This is strictly a parts identification catalog. Torque values, disassembly procedures, and troubleshooting are in the service manual. Use this catalog to order the right parts, then refer to the service manual for installation specs.

How do I use the group number index to find a part fast?

Open the front of the manual. The index lists each basic system (engine, transmission, etc.) with its starting group number. For example, “Hydraulic System” begins with group 32. Turn to the page indicated. Each illustration has numbered callouts. Match the callout number to the parts list on the opposite page or below the illustration. That list gives the OEM part number, description, and quantity per machine. Write down the part number exactly as shown – O&K uses dashes and sometimes leading zeros. If you order using the illustration reference number and the group, the dealer will have an easier time verifying the part against your serial number.

Stop wasting money on wrong parts and time on returns. This 286-page OEM catalog puts the exact O&K part number in front of you. Access the Factory Manual now and get back to fixing the machine.
