JCB 2D, 700, 3MKIII, 3CII, 3DII Parts Catalog

If you’ve ever been halfway through a backhoe rebuild and realized the part number you ordered doesn’t match the old one because someone swapped a different dipper assembly before you got the machine, you know the pain. I’ve seen it too many times in my shop. Guys guess at part numbers, cross-reference from aftermarket catalogs, and end up with the wrong stabiliser leg or a kingpost that doesn’t fit. That’s where a factory JCB 2D, 700, 3MKIII, 3CII, 3DII Parts Catalog comes in. 20 pages of part numbers, exploded views, and change notes. That’s it.

Page 1 shows the index: B1 Shovel, B2 Bodywork, B3 Cab & Seat, B4 Backhoe, B5 Miscellaneous, B6 International Harvester. Each section is broken down by model and includes change numbers so you can track superseded parts. My point? This isn’t a reprint from some third party who scanned a manual and left out the small print. This is the original factory file, exactly as JCB issued it.

B4 Backhoe: What the 20-Page Catalog Covers

The backhoe section (B4) is the meat of this catalog. Page 2 gives you the overview: Actuator, Boom, Dipper (Standard and JCB Extending), Kingpost, Kingpost Carriage, Lever & Link (Slewing and JCB Extending Dipper), and Stabiliser. For each sub-section, the table lists which page the exploded view lives on for each model: 2D, 3MIII, 3DII, 4D. Note that the 700 and 3CII models aren’t separately listed in that table, but the part numbers for those models are woven into the same exploded view pages. You just match the change number to your machine’s serial range. Cross-reference with JCB Excavator Loader Workshop Manual 2D/3 Range for service procedures.

Stabiliser Assembly Exploded View – Page 3

Flip to page 3 and you get the B9-1 Stabiliser. Twenty-four items with part numbers, change numbers, and quantities per build for 2D, 3MIII, 3DII, and 4D. For example, item 1 is sliding leg 107/02600 up to M17649, superseded by 107/02700. That kind of detail saves you from ordering a leg that won’t fit your older machine. I’ve watched guys waste a full day because they didn’t check the change number. Don’t be that guy. If you also work on JCB loaders, the JCB JCB1 Parts Catalog – 94 Pages of Factory Part Numbers covers a different family but same level of detail.

Kingpost and Kingpost Carriage – Critical Part Numbers

Page 5 shows the B10-1 Kingpost. Item 1 is the kingpost itself – part 99C/400 to M16594, then 109/41600. Notice the note: “M/a use 1 109/41600 with 100/29201 & 808/00127.” That’s the kind of cross-reference you never get from a generic parts list. The roller guide (item 24) and pipe assemblies (items 2-8) are all listed with restrictor notes. If you need the kingpost carriage, that’s B11-1 on another page. The JCB 1D Parts Catalog – Factory Part Numbers & Exploded Views covers the 1D line if you’re working on a smaller machine.

Who Needs This Catalog?

Home garage guys who bought a used JCB backhoe and need to order parts without guessing. DIY mechanics who want to tear down the stabiliser or kingpost and know exactly which bushings and pins to buy beforehand. Beginner owners who don’t want to pay dealer markup for a part that turns out to be wrong. And yes, professional shop owners like me who keep a library of factory parts catalogs on the tablet so my techs don’t waste billable hours hunting part numbers. If you want to understand how the diesel engine itself works, this Wikipedia article on diesel engines gives you theory, but for actual part numbers you need the catalog.

OEM vs Aftermarket: Why Factory Change Numbers Matter

Aftermarket catalogs often skip the change notes. They show one part number and call it done. But JCB issued multiple supersessions for the same component. On page 3, the stabiliser pivot pin 1019/2028 has a correction note – it used to be 1019/2043. Without that note, you’d order the wrong pin. The factory catalog also includes labels and transfers (items 18-21 on page 3) that are specific to Swiss builds. Third-party reprints don’t bother with that. This is the real thing. For deeper engine knowledge, this Wikipedia article on diesel engines is a good read, but it won’t tell you the part number for a kingpost roller guide.

B6 International Harvester Section – What It Contains

The index lists B6 International Harvester on page 1. That section covers parts specific to machines fitted with International Harvester engines or driveline components. If your JCB has an IH power unit, you’ll find the relevant part numbers and exploded views there. The catalog doesn’t break it down further in the excerpt, but the page numbers are consistent with the rest of the document.

Does this catalog include part numbers for the 700 model?

Yes. The 700 model is listed in the product title and appears in the exploded view tables. You’ll find its part numbers alongside those for 2D, 3MKIII, 3CII, and 3DII.

How many pages is the Parts Catalog?

20 pages.

Can I use this catalog to order parts for a 3CII backhoe?

Absolutely. The 3CII is one of the covered models. The B4 Backhoe section includes part numbers and change notes specific to 3CII builds. Cross-check your machine’s serial number against the change numbers in the tables.

Does the catalog cover the International Harvester section for engine components?

Yes, but the International Harvester section (B6) is listed in the index on page 1. However, the catalog is primarily for the excavator and framework sections. The IH section likely covers specific adaptations for International Harvester engines or chassis. You would need to verify the part numbers against your machine’s serial number. The catalog includes change numbers, so you can track superseded parts. For example, on page 3, the stabiliser section shows multiple change numbers for sliding legs. That level of detail is why you want the factory document, not a reprint.

If you’re tired of guessing part numbers and wasting time and money on wrong parts, this 20-page factory document is what you need. Access the Factory Manual and get the right parts the first time.
