Clark-hurth 380 Parts Catalog – Factory OEM Documentation

I've been turning wrenches since before some of you were born, and I've seen too many guys order the wrong seal because they used a third-party parts list. This Clark-hurth 380 Parts Catalog is the real thing – 108 pages of OEM part numbers and exploded views that came straight from the factory. You want to rebuild a transmission on a 380 III Tractor Dozer? You need this. You want to replace a brake accumulator without chasing supersessions for two days? This is what you pull off the shelf.

What This Parts Catalog Covers

The index alone tells you this isn't some generic parts list. You get dedicated sections for Accelerator Pedal and Linkage (page 7), Air Cleaner Assembly and Element (page 9), Front and Rear Drive Axle Assemblies (pages 41, 45), Brake Air Lines and Accumulator (pages 61–63), Transmission Shift Control Accumulator (page 35), Torque Converter Air Breather (pages 31, 33), and the Parking Brake Assembly (page 51). Every major system on the 380 III – from the battery compartment to the exhaust pipe – has its own exploded diagram with callouts. I don't care if you're a home-garage guy with a tired dozer or a shop foreman juggling three rebuilds; having the factory grouping saves you time hunting for the right part number.

Factory Parts: The Real Difference Over Aftermarket

Aftermarket catalogs love to mash multiple models into one chart, then omit the superseded part numbers that fix known failures. This Clark-hurth original tells you exactly which serial number range uses which part. Look at the cover page: it lists 380 III G.M. machines from 41RG101 thru 4RG999, and tells you that later serial ranges (5RG, 6RG, etc.) and optional power plants have supplements at the back. That kind of detail is why I won't let a junior tech touch a parts call without the factory manual in front of him. You pay for this catalog once, and you stop throwing money at wrong parts.

When You Need This Catalog on the Bench

You've got the transmission out on a 380 III, and the clutch pack seals are shot. The parts counter guy reads you a number from his cross-reference – but you've been burned before. Pull out this catalog, flip to the Transmission section (starting around page 17), find the air breather assembly, and verify every O-ring and gasket by the exploded view. Same goes for brake work: the Automatic Brake Adjuster Assembly (page 62) and the Brake Valve Assembly – Hydraulic (page 59) are separate illustrations, so you don't confuse the accumulator with the control valve. I've seen guys do that. It ain't pretty.

Torque Converter and Transmission Coverage

Any drivetrain overhaul demands correct part numbers for the torque converter and transmission components. This catalog gives you the Air Breather – Torque Converter (referenced on pages 31 and 33) and the Transmission Shift Control Accumulator (page 35). You also get the Transmission Air Breather (page 17) and the Transmission Mounting Brackets (page 17). If you're rebuilding the power shift, you need those accumulator parts – and the OEM listing will match your serial number. Don't chase ghosts with aftermarket cross-references.

How to Use the 108 Pages Effectively

Start by finding your machine serial number on the ID plate. Write it in the box on page 1 – that's what the factory intended. Then use the index (pages 3–4) to locate the component group. Each group has a page number; every drawing has callout numbers that map to a parts list with descriptions and quantities. If your serial number falls into a later range, check the supplements at the rear. This isn't rocket science, but skipping steps will cost you. Related manuals you might want to have on hand include Clark-hurth L320 1991 Parts Catalog – 690 Pages OEM Specs for larger loaders, the Clark-hurth 85III 1965 Parts Catalog – Factory OEM Specs for older models, and the Clark-hurth 85A, 85A1 1978 Parts Catalog – OEM Factory Specs for mid-size equipment. For background on the engines used, an Internal Combustion Engine overview can help you understand the power plant, but for parts you stick to the factory catalog.

Frequently Asked Questions

Does this parts catalog include repair procedures or torque specs?

No. This is a parts catalog, not a service manual. You need the OEM service manual for disassembly, assembly, and torque values. Use this catalog to order the correct parts before you start the job.

What machines does this cover?

It covers the Model 380 III Tractor Dozer, with serial numbers 41RG101 through 4RG999 for G.M.-powered machines. Later serial ranges and optional power plants have supplements at the back of the catalog.

How do I find the correct part number from the exploded diagrams?

Use the alphabetical index at the front to find the system (e.g., Brake Air Lines). Turn to the page listed. The exploded drawing shows numbers next to each part. Those numbers correspond to a parts table on the same page or facing page that lists the part number, description, and quantity. Always cross-check your machine serial number because later models may use different parts listed in the supplement.

Is this a reprint of an aftermarket document?

No. This is a direct scan of the original Clark Equipment Company factory parts manual. No aftermarket editing, no missing pages.

If you're working on a Clark-hurth 380 III, you need the factory parts list on your bench. Stop wasting time with cross-references that lie to you. Access the Factory Manual from AutoRepairManuals and get the right part the first time.
