Clark Equipment 375A Parts Catalog – Factory Parts Breakdown for Tractor Shovel

If you’ve ever ordered a cylinder seal kit for a Clark 375A and ended up with the wrong stack height because you trusted a third-party parts list, you already know the frustration. That downtime costs money. This is the 122-page OEM Parts Catalog — not a reprint, not a scan of a scan, but the actual factory document that Clark Equipment issued for the Model 375A Tractor Shovel. It gives you the exact part numbers, exploded views, and assembly relationships so you don’t waste time guessing what goes where.

Boom and Cylinder Assembly: Pages 70–71

The boom cylinder assembly (page 70) and bucket cylinder assembly (page 71) are fully broken down with individual part callouts. You see the seal kit, piston rod, gland, and every snap ring. Need the bucket cylinder’s piston seal part number? It’s listed right next to the illustration. No flipping between sections to cross-reference. This is the difference between ordering the right parts the first time and having the machine sit idle for three days while you wait for a return.

What the Wiring Section Covers (Page 89)

Battery and wiring are on page 89. It’s not a schematic — it’s a parts breakdown that shows the harness routing, the ammeter connections, and the individual wire part numbers. If you’re rewiring a 375A that’s been hacked together by three previous owners, this page alone saves you hours of tracing circuits. And it’s factory-correct, not a generic drawing that leaves out the ground straps.

Engine and Accessories: Page 1 Breakdown

Page 1 covers the engine and accessories section. You get the compressor drive belt, engine fan, oil pressure sender unit, and temperature sender — all with Clark part numbers. Most aftermarket catalogs skip the sender units or list them as “equivalent to.” This manual gives you the OEM number, so you match the calibration range. Your temp gauge reads correctly because you used the right sender, not a substitute.

Front and Rear Axle Differences: Pages 45–50

The front drive axle (page 45) and rear drive steer axle (page 47) are separate assemblies with different differential carriers (pages 49–50). The air chambers for front and rear brakes are on pages 76–77. If you try to swap a front air chamber onto the rear axle, the mounting bracket won’t line up. The manual shows each component specific to its position. No generic “axle assembly” — it’s axle assembly—front drive vs. rear drive steer.

7 Sections Covering the Bucket and Boom Hydraulic System

The bucket and boom hydraulic pump is on page 64, the hydraulic oil reservoir and parts on page 66, the engine by-pass oil filter on page 67, and the bucket and boom hydraulic system overview on page 69. The control valve assembly is on page 73. That’s five separate sections dedicated to the hydraulics alone. If you’re rebuilding a steering cylinder (page 56) or the boom cylinder, you need each seal, each O-ring, and each backup washer. This catalog provides that detail.

Why OEM Factory Data Matters for the Clark 375A

Clark Equipment printed this manual for their distributors and service departments. Every part number was verified against the production line. Aftermarket parts suppliers create their own catalogs by measuring parts and guessing interchange — and they get it wrong. I’ve seen a hydraulic pump listed as interchangeable when the shaft spline count differed by two teeth. That mistake costs you a pump and a day. The Clark Equipment 375A Parts Catalog eliminates that risk.

FAQ

Does this parts catalog include torque values or assembly procedures?

No. This is a parts catalog, not a service manual. It lists every part with its number and shows exploded views, but it does not provide torque specs or step-by-step repair instructions. For those, you need the corresponding service manual for the 375A.

How do I verify that a part number is still current?

Clark Equipment changed part numbers over the years. Always cross-reference your machine’s serial number with the list on page 1 and the clip chart on page 90 before ordering.

Access the Factory Manual and keep it on your tablet or printed in the shop. When the boom cylinder starts leaking at 6 p.m. on a Friday, you’ll have the right part number to call your distributor first thing Monday morning — and the machine goes back to work instead of sitting. That’s why this 122-page catalog belongs on your workbench.
