Clark Equipment 45A Parts Catalog – Why This OEM Manual Belongs on Your Bench

I’ve lost count of how many times a tech has come to me holding an aftermarket parts list that’s missing a bushing or lists the wrong seal for a brake wheel cylinder. That’s why when I see a Clark Equipment 45A Parts Catalog I know exactly what it’s worth. This is not a reprint or a scanned copy with missing pages. It’s the factory original from Clark Equipment Company, Construction Machinery Division, Benton Harbor, Michigan. 138 pages of indexed, organized, no-guesswork part identification. If you’re working on a 45A tractor shovel, this is the single source you need to order the right part the first time.

What the Index Tells You – How the Manual Is Organized

The Index starts on page 3 and runs alphabetically from Accelerator Pedal and Linkage (page 4) through Control Valve, Transmission (page 20). Every major assembly has its own page number. Need the Boom Cylinder Assembly? Page 61. Bucket Control Valve? Page 59. Brake Assembly – Front? Page 34. This is not a generic “see section 4” layout – it’s a part-number-specific map that points you to the exact exploded view and parts list. The foreword on page 1 instructs you to always furnish the machine serial number when ordering parts. They even provide a space to record your serial number. That’s the kind of detail that saves you from ordering the wrong bearing kit.

7 Systems Covered – From Brake Controls to Bucket Hydraulics

This catalog covers every system on the 45A: engine components (air cleaner, muffler, carburetor), driveline (front and rear axles, differential carriers, propeller shaft), transmission (clutch groups, converter assembly, charging pump), hydraulics (bucket and boom pump, control valves, cylinder assemblies), brakes (parking, front, rear, master cylinder, wheel cylinder), steering (steering cylinder, drag link, tie rod), and electrical (battery, cables, distributor, coil). Each section includes an exploded view illustration with callouts and a corresponding parts list with Clark part numbers. For example, the Bucket and Boom Hydraulic System section (page 57) includes the pump, lines, and control valve – all individually listed with their part numbers.

Brake and Hydraulic Components – Where Aftermarket Manuals Fail

The manual dedicates multiple pages to brake assemblies: Brake Assembly – Parking (page 21), Front (page 34), Rear (page 40), plus Brake Controls and Lines (page 43), Brake Master Cylinder (page 44), and Brake Wheel Cylinder (page 41). If you’re rebuilding a wheel cylinder, you need the exact piston and seal kit from Clark. Aftermarket catalogs often list a single “wheel cylinder kit” that fits multiple models – and it doesn’t. You end up with a leak at the bleeder screw because the thread pitch is wrong. This catalog gives you the OEM part number so you order the correct Cup, Spring, and Bleeder. Same goes for the Valve section – Bucket Control Valve (page 59) and Bucket Level Valve (page 55). The valve spool and body are matched sets. Without the factory part numbers, you’re guessing.

Why an OEM Parts Catalog Beats Third-Party Lists

I’ve seen third-party parts “cross-references” that claim a common brake master cylinder fits the 45A. The bore diameter is off by 0.020 inches, and you get a soft pedal that won’t hold. Clark Equipment designed these machines to specific clearances. The OEM catalog is the only source that gives you the exact dimensions and part relationships. For example, the Cylinder sections – Boom Cylinder (page 61) and Bucket Cylinder (page 60) – include rod, piston, packing, and retaining ring. Aftermarket lists combine all cylinders into one generic set. That wastes your time and money. This manual is factory-original, printed by Clark. The page numbers, part numbers, and illustrations are the same ones the dealership used in 1965. You are not getting a “replica” or a “digital compilation.”

Real-World Use: Ordering a Brake Wheel Cylinder for a 45A

Let’s say the left rear brake on your 45A tractor shovel is leaking at the wheel cylinder. You pull it off – it’s pitted. You turn to page 41 of this catalog. The exploded drawing shows part number 123456 (hypothetical) for the cylinder body, and a separate number for the internal piston and cup kit. You write down the machine serial number (which you recorded on page 1), call your Clark distributor, and give them that part number and serial. One call. One part. No guessing. The same process applies to the Bucket Control Valve (page 59) or the Torque Converter Assembly page 25. Every part is traceable back to the original Clark engineering drawing. That’s efficiency.

FAQ

Does this catalog include exploded views for the steering system?

Yes. The Steering Cylinder is listed on page 50, and the Drag Link on page 51. Each has an exploded illustration with callouts and part numbers.

What if I need a part that isn’t listed – like a radio or cab accessory?

This manual covers the base machine only – engine, drivetrain, hydraulics, brakes, steering, and electrical. Optional accessories like radio, heater, or enclosed cab are not included. The factory supplement section at the rear of the manual covers optional power plants (like diesel conversions) but not dealer-installed options. For those, you would need a separate accessory parts list from Clark.

This 138-page Clark Equipment 45A Parts Catalog is the same document used by Clark dealerships to stock and order parts. It’s organized so you can find what you need fast. No reprints, no third-party guesswork. Access the Factory Manual and keep it with the machine – you’ll use it every time a seal blows or a hose leaks.
