Clark Equipment 275A Parts Catalog

If you have spent a Saturday afternoon with a part that looked right but did not fit, you know what I mean. Aftermarket catalogs and generic parts lists are guesswork dressed up as data. This is the OEM factory Parts Catalog for the Clark Equipment 275A Series I tractor shovel. It is 160 pages of the exact part numbers Clark shipped when these machines left the factory. No reinterpretation. No photocopy of a photocopy. This is the original document, straight from the engineers who designed the brake groups, the axle assemblies, and the hydraulic system.

Why You Need the OEM Parts Catalog for the Clark 275A

A service manual tells you how to take it apart. A parts catalog tells you what to put back in. When you are ordering a Brake air chamber for the front axle, you need the right group number. The Clark 275A uses different brake air chambers for front and rear – pages 80-81 show the front assembly, page 82 covers the rear. Order the wrong one and you are looking at a week of downtime waiting for the exchange. This catalog eliminates that risk.

What’s Inside: Brake Groups, Axles, and More

The table of contents runs from Accelerator Pedal (page 27) to the Wiring diagram pages. You get the full drivetrain breakdown – front drive axle on page 67, rear drive steer axle on pages 71-72. The “A”-Second and Fourth Drive Shaft Group (page 45) and the “B”-First and Third Drive Shaft Group (page 47) are both indexed. Clutch covers, converter assembly torque converter (pages 57-58), and the entire bucket and boom hydraulic pump section (pages 109-111) appear with their own part numbers.

160 Pages of Factory Part Numbers

Every page is a numbered illustration with a corresponding parts list. For example, the Brake Air Lines section (pages 85, 87, 88) includes air reservoir, air compressor governor, and air horn parts. You get clip diagrams on pages 133-135. The cab assembly is on page 129. Battery and wiring on page 124. This is not a reprint of a third-party scan – it is the original Clark Equipment file, serial number specific (27123 thru 27399 Cummins, 1JG1 thru 1JG999 GM).

How This Catalog Saves You from Ordering Wrong Parts

You are staring at a rusted brake air chamber with a missing tag. Without the factory illustration, you guess between the front and rear chamber. With this catalog, you flip to page 80, find the exploded view, match the shape, and write down the part number. Then you cross-check it on page 82 for the rear chamber just to be sure. That is the difference between a one-hour order and a three-week return nightmare.

Real-World Use Case: Rebuilding the Brake Air System

Take the brake air lines – pages 85, 87, 88 list every fitting, line, and bracket. The air reservoir, governor, and sender unit all have separate part numbers. You can order the exact cartridge kit for the bypass oil filter (page 2-3) or the steering filter cartridge (pages 95, 97, 99) without guessing which thread pitch fits. That is the kind of detail that makes a difference on a Saturday job with the machine down.

Source Authenticity: OEM vs. Aftermarket

Clark Equipment printed this manual as Parts Manual No. 1688-R1. The front page says “Information contained herein pertains only to Machine Serial Numbers listed below.” Aftermarket catalogs often combine multiple series or omit serial number ranges. That is where the mistakes come from. This document is the original – no redrawn illustrations, no renumbered pages, no generic “fits all” descriptions.

Frequently Asked Questions

Does this catalog include the boom cylinder assembly?

Yes – boom cylinder assembly is on page 116, bucket cylinder assembly on page 117. Both have exploded views and part numbers.

How do I find the part number for the brake air chamber?

Use the index heading “Brake Air Chamber, Front” on page 80-81. The illustration shows the chamber, mounting bracket, and all hardware. Write down the part number from the adjacent list.

Are torque specifications included?

No. This is a parts catalog, not a service manual. It lists part numbers and quantities only. For torque specs, you need the corresponding service manual for the Clark 275A. Our site carries that separately.

Can I use this catalog for serial numbers outside the listed range?

The manual explicitly covers Clark 275A Cummins machines from 27123 to 27399 and 1JC265 to 1JC999, plus GM machines from 1JG1 to 1JG999. Using it for other serial numbers is risky – internal components may differ in later production runs. Verify your machine serial number before ordering parts.
