JCB 112, 114 1981 Parts Catalog

You’ve got a JCB 112 or 114 sitting in the yard with a blown hydraulic hose. You call the dealer, they ask for a part number. You don’t have it. So you guess, order three hoses, and two are wrong. That costs time and money. I’ve been turning wrenches for 28 years, and I tell you: the JCB 112, 114 1981 Parts Catalog is the only way to get the right part the first time. This is the original factory print, not some aftermarket photocopy. It gives you the exact part numbers, exploded views, and supersession data that dealers use. Skip the guesswork.

What’s Inside the JCB 112/114 Parts Catalog?

Thick as a phone book at 198 pages, this catalog breaks the machine into eight lettered sections. On page 1 you’ll find the numerical index and the section keys: Buckets & Attachments (A), Body & Framework (B), Machine Electrics (C), Controls (D), Hydraulics (E), Transmission (F), Brakes (G), and Track & Running Gear (J). Every nut, bolt, hose, and seal is listed with a factory part number. Need a bucket edge for a 6-in-1? Section A. A loader arm assembly? Section B. The catalog is built around the machine serial number, so you order the correct revision.

Machine Electrics Section – Wiring and Components

The Electrical section (C) covers the full layout: electrical equipment, instrumentation, heater, bucket reset, beacon light, and windscreen washer. If the alternator or starter motor fails, you get the JCB part number, not a cross-reference that may or may not fit. The diagrams show exactly where each wire runs. For a machine that lives outdoors, electrical gremlins are common. This catalog gets you the correct switch, bulb, or harness assembly without pulling your hair out.

Hydraulics Coverage – Filters, Pumps, Valves

Section E is the biggest in the book. Hydraulics make the JCB 112/114 work – loader, transmission, anti-stall, 6-in-1 bucket, ripper, cab lifting. The catalog breaks down circuits, filters (loader, transmission, anti-stall), pumps and adapters, motors (internal and external), and valves. Valves alone have subsections for servo, composite, changeover, selector, loader, and spools for bucket, lift, and clam/ripper rams. Every ram – bucket, lift, clam, ripper – is listed with its seal kit part number. If you’ve ever rebuilt a ram and had one seal too big, you know why the factory listing matters. this Wikipedia article on diesel engines gives background on the power source, but for the hydraulics you need this catalog.

How to Use the Indenting System

Flip to page 3. There you see the indenting system explained: a working light kit (item 1) includes the light (2), which includes the lens (3) and bulb (4). The catalog groups them with indents so you order the assembly or the individual piece. Also on page 3 is the part number change method. When a part is superseded, the new number sits below the old one with the machine serial number where the change happened. Example: 447/05200 superseded by 447/06800 – interchangeable. If you see ‘R’ in the remarks column, you can order a reconditioned exchange unit by adding R to the part number. This system saves you from ordering a part that won’t physically fit.

Why an OEM Parts Catalog Beats Aftermarket Lists

Aftermarket catalogs compile numbers from multiple sources. One typo and you get the wrong gasket. This is the JCB factory document – Issue 2, December 1981. The part numbers are verified against the actual machine builds. The catalog includes amendment instructions: Number Change Supplements (N.C.S.) and replacement pages. You get the real structure. If you are working on a JCB 112 or 114, you need the factory numbers. I’ve seen techs order from generic lists and end up with a track roller that is 2mm too wide. Don’t be that guy. If you need similar manuals for other models, check out JCB JCB1 Parts Catalog – 94 Pages of Factory Part Numbers, JCB 1D Parts Catalog – Factory Part Numbers & Exploded Views, or JCB 7, 7C, 8C, 8D Parts Catalog – 497 Pages of OEM Part Numbers.

Frequently Asked Questions

Does this parts catalog cover both the JCB 112 and 114 models?

Yes, the catalog covers both the JCB 112 and 114 crawler loading shovels from 1981. The sections are combined, with part numbers applicable to both unless noted by serial number.

Can I use this catalog to order parts for a machine built in a different year?

It is specific to 1981. Later models may have different part numbers. Always verify with the machine serial number.

What if I need a part that has been superseded?

The catalog includes a system where new part numbers are listed below the original, with the machine serial number at which the change takes effect. It also shows ‘Superseded’ or ‘N/A Use’ if interchangeable. For example, on page 3 you see part numbers 447/05200 superseded by 447/06800. So you can order the correct updated part. This prevents ordering obsolete inventory that won’t bolt up. If you have a machine built after the change, the new number is what you want.

Is this a PDF or a physical manual?

It is a digital PDF file with 198 pages. You access it and can print or view on any device.
