Clark Equipment 310, 310III Parts Catalog – OEM Index

Description

New guy pulled a brake chamber off a Clark 310III last week and ordered a replacement from memory. Two days later, the part didn’t fit. Wrong air brake valve. Cost him a weekend and a rental charge. That’s why you need the Clark Equipment 310, 310III Parts Catalog on your bench. This is the original factory document, not a third-party reprint. It lists every component by exact part number and links it to the machine serial number range.

Brake System Components: Air Brake Valve and Slack Adjuster

Brake system parts are scattered across pages 51 through 55. The slack adjuster and air chamber live on page 51. The air brake valve appears on page 53. The brake controls, including the air brake valve linkage and check valve, are grouped together. If you’re rebuilding the brake system on a 310 or 310III, you pull the part numbers from these pages. The manual also lists the brake shield separately on page 9, so don’t assume everything is in one cluster. Work through the index carefully. Page 51 and page 53 are your starting points for the service brakes. For the body section of the scraper, refer to the MICHIGAN Model 310 TRACTOR SCRAPER Parts Manual. If you’re also working on newer Clark equipment, the Clark Equipment 75B 1989 Parts Catalog – OEM Factory Manual is available. And for cross-referencing with other scraper manufacturers, the Hancock Parts Manual No. 1008 for Model 12E2E Scraper may be useful.

What Does a Parts Catalog Do for a Mechanic?

A parts catalog is not a repair manual. It tells you what to order, not how to install it. But if you’re stocking a shop or tracking down a superseded part, this is the only source that matches the original build. The index starts on page 1: accelerator linkage, air cleaner caps, battery box. Every assembly is listed A to Z. You find your component, note the page, then verify the part number against your machine serial number. That process eliminates returns. I’ve seen guys order a steering bell crank without checking the serial number break — wasted two weeks.

96 Pages of Part Numbers – No Generic Substitutes

The catalog is 96 pages of exploded views and parts lists. For the 310III tractor section, you get the front axle housing, transmission case, clutch cover group, steering bell cranks, air compressor governor, and everything in between. The table of contents alone covers over 200 line items. When you order a part from this document, you get the Clark-Approved part. That means it fits, it seals, it lasts. The difference between an OEM part and a generic replacement is often a few thousandths of an inch in a seal bore. This catalog gives you the factory number.

Match Your Serial Number to the Correct Section

Your machine serial number range is printed on page 1. If your 310 or 310III falls in 4VG101 through 4VG999, this catalog is correct. The body section is a separate manual (No. 2101). Don’t order tractor parts from the body manual. Write your serial number in the box on page 1 and keep it with the manual. When you call your Clark distributor, give them that number. They need it to pull the right part. I always tell the junior guys: serial number first, part number second.

Air Cleaner and Intake System Parts

Air cleaner caps on page 2, air cleaner element on page 3, connections and cup also listed. If you’re servicing the intake on a 310, you can see exactly which pre-cleaner cap and element you need. The manual even shows the air cleaner cup separate from the element. That level of detail saves a return trip to the parts counter. The air cleaner element is a common mix-up — don’t guess the part number. Use the manual.

FAQ — Clark 310, 310III Parts Catalog

Do I need to order a separate manual for the body section?

Yes. The body section has its own manual, part number 2101.

How do I find the correct part number for a brake slack adjuster?

Turn to page 51 in the index. You’ll see “Adjuster, Brake Slack” listed. Flip to that page. The illustration shows the adjuster assembly with its part number. Cross-reference that number with your machine serial number. Clark Equipment issued multiple revisions; the catalog accounts for serial number breaks. If your machine is outside the 4VG101-4VG999 range, this manual may not cover it. Order only after verifying your serial number against the header on page 1.

Is this catalog usable for a 310III without the body section?

Yes. The tractor section is self-contained. You get all powertrain, steering, brake, and electrical parts. The body section is separate manual 2101.

Why should I trust this over an online parts list?

Online parts lists often combine multiple models, skip supersession history, or use generic images. This is the original Clark Equipment Company print. Every part number traces back to the engineering drawing. If it’s listed here, it’s the factory-correct component. Aftermarket catalogs rarely have the same level of detail for items like the air brake valve check valve or the transmission clutch cover group. You pay for accuracy.

For a broader understanding of heavy equipment manufacturing, see Automotive Industry Overview and Automotive Industry Overview. When you are sourcing parts for a Clark 310 or 310III scraper, this catalog is the reference that keeps your bench clean of wrong parts. I’ve worked on these machines for years, and the difference between using the OEM parts catalog and an aftermarket list is the difference between a job done in a day and a job that drags into three. Every time you order a part without verifying the number against this manual, you gamble with fitment. The brake slack adjuster on a 310III is not the same as on a 310 — the manual makes that clear. Get the correct part number the first time. Access the Factory Manual from AutoRepairManuals and put it in the drawer next to your torque wrench.
