Clark Equipment 275 Parts Catalog – Factory OEM Manual

You’ve got a Clark 275 with a blown hydraulic pump or a worn brake chamber. You need the exact part number, not a catalog that says “fits similar models.” The Clark Equipment 275 Parts Catalog is the factory document from Clark Equipment Company. 130 pages of exploded views and part numbers. I’ve used factory parts catalogs for 28 years as an ASE Master Technician. Anything else wastes time and risks ordering wrong parts.

Factory parts catalogs from Clark are the only source that matches every bolt, seal, and gasket to the machine serial number. This one covers serial 425A101 and after. That’s the difference between a repair that holds and a do-over.

Engine and Transmission: What the Parts Catalog Covers

Engine accessories are listed on page 43. You’ll find part numbers for the air cleaner, fuel system components, and the engine-mounted charging pump. The transmission section starts on page 37 with the converter assembly, the cartridge filter kit, and the control cover assembly. Page 37 also shows the converter charging pump and pressure regulating valve. Every internal part of the transmission case is identified — clutch groups, seals, bearings. If you are rebuilding a 275 transmission, this catalog tells you exactly what to buy.

Brake and Valve Systems – Don’t Guess on Safety Parts

Brake components are spread across multiple pages because the 275 uses air-over-hydraulic braking. The Air Brake Valve is on page 35, the Brake Assembly (front and rear) on page 51, and the Parking Brake assembly on page 52. The Slack Adjuster is on page 61. If you are ordering brake parts, you need these page numbers to cross-reference with your machine. I’ve seen guys order the wrong air chamber because they used an aftermarket catalog. Page 12 has the Air Chamber. Don’t waste labor on returns.

130 Pages of Identified Components

That’s 130 pages of indexed part numbers. The index at the front runs from Accelerator Pedal (page 16) to Control Valve Assembly, Main (pages 80-84). Exploded diagrams show each part with a leader line to the part number. No guesswork. Need the bucket cylinder assembly? Page 76. Boom cylinder assembly? Page 77. Steering cylinder? Page 62. The catalog covers the whole machine: front and rear axles, cab, electrical, hydraulic system, and bucket assembly data on page 7.

How This Catalog Saves You Time on Repairs

When a part fails, you look up the assembly in the diagram, read the part number, and order it. No measuring castle nuts to guess thread size. No calling the dealer with a vague description. For example, the main control valve assembly on pages 80-84 has individual spools, springs, and plugs. You can order just the worn spool instead of the whole valve. That’s real money saved. Pair this catalog with the factory service manual and you have the complete repair package.

Torque and Fastener Data

This parts catalog does not list torque values — that’s in the service manual. But it does list every fastener with Clark part numbers. When you look up a bolt part number, you can then find the correct torque specification in the service manual. That linkage is critical. If you buy a generic bolt, you lose the torque data. Always use the factory part number to keep the torque chain intact.

Does this parts catalog include torque specifications?

No, this is a parts catalog. Torque specs are in the service manual.

Can I use this to rebuild the transmission?

Yes, but you need the service manual for disassembly steps. This catalog provides part numbers for every internal component: clutches, seals, bearings, converter, and the transmission case. You’ll identify exactly what to order for the input clutch group or the reverse-third-fourth clutch. Pair it with the factory service manual for the rebuild procedure. Without the parts catalog, you risk ordering the wrong clutch pack or missing a seal.

Does this cover the bucket and boom hydraulic system?

Yes. Pages 73-75 cover the bucket and boom hydraulic pump and system. The catalog includes part numbers for cylinders, hoses, and the main control valve assembly on pages 80-84. You’ll also find the pilot control valve on pages 87-89.

What serial numbers does this cover?

This manual covers Clark 275 Cummins machines with serial numbers 425A101 and after. Always verify your serial number before ordering parts.
