JCB CONTRACTOR 150T, FASTRAC 125, FASTRAC 135T, FASTRAC 145T, FASTRAC 155T Parts Catalog

You just tore down a front weight tray assembly on a FASTRAC 155T because some clown guessed at a part number and ordered the wrong counterweight bracket. Now you got a 40kg lump that doesn’t fit, a customer breathing down your neck, and a machine sitting on jack stands. I’ve seen it happen more times than I want to count. That’s why a factory JCB CONTRACTOR 150T, FASTRAC 125, FASTRAC 135T, FASTRAC 145T, FASTRAC 155T Parts Catalog belongs on your bench, not some aftermarket PDF that leaves out the serial number breaks.

What the Parts Catalog Actually Covers

1,651 pages of exploded-view diagrams, part numbers, change numbers, and usage codes. Every machine group listed: CONTRACTOR 150T, FASTRAC 125, FASTRAC 135T, FASTRAC 145T, FASTRAC 155T (plus the 185Ti variants). The manual breaks down assemblies like the weight tray assembly (front, with and without hitch), swinging drawbar with PITON option, ladder hitch, and more. You get item numbers, part numbers, descriptions, and quantities. For example, the front weight tray assembly (page 1–4 of the catalog) shows 40kg counterweights (part 476/80101), fixing pins, top links, and CAT 3-2 balls. Serial number ranges are included so you order the right frame — 477/06400 up to S/N 636226, then 477/35400 up to 636440, etc. That level of detail keeps you from ordering the wrong bracket.

1651 Pages – Why Size Matters

That’s not a typo. 1,651 pages of factory part numbers, exploded views, and revision notes. You get every supersession, every change number, every nut and bolt. The weight tray assembly alone has 11 line items per page, with part numbers like 476/80103 (fixing pin), 826/01166 (lynch pin), and 1370/0701Z (nut). Need to find a stud bar for the weight retainer? It’s item 9 on the first page: 826/01248. The catalog doesn’t skip steps. It shows you the assembly, then gives you the machine groups that use it. This isn’t a service manual; it’s a parts catalog. You don’t get torque specs or repair procedures here — you get the exact part numbers so you call the dealer with the right info.

Parts Catalogs vs. Aftermarket: Spot the Difference

I’ve seen third-party catalogs that list “counterweight, 40kg” without the change number or serial number break. Then you order the part, it shows up with a different bolt pattern, and you’re stuck. This JCB parts catalog is OEM. Look at page 5 of the swinging drawbar section: part 477/00900 (hitch, ladder, short) for SCHARMULLER, versus 476/83400 (hitch, ladder) for ROCKINGER — with a serial number cutoff at S/N 636433. Third-party reprints often merge these into one line. That gets you a hitch that doesn’t bolt up. The change codes (e.g., “Superseded” or “M.S.S Multi Supersession”) tell you exactly what superseded what. You can trace the part history. That’s the difference between a job that takes half an hour and one that takes half a day.

Who Needs This JCB Parts Catalog?

If you wrench on CONTRACTOR 150T or any FASTRAC 125 through 155T machines — either in a dealer shop or your own garage — you need this. The home mechanic who tries to cross-reference a part number from an online forum will waste money on returns. The professional tech who bills by the hour can’t afford to gamble. Even a workshop owner who stocks parts should have this catalog to verify incoming inventory. Real-world use case: You’re rebuilding the front weight tray on a FASTRAC 135T that lost a lynch pin. The aftermarket website says “fits all models.” The catalog shows you that item 4 (826/01166) is a lynch pin — but only one is used on the no-hitch version, while the with-hitch version uses five. Order five instead of one? That’s $15 down the drain. Or order the wrong pin diameter? Machine won’t hold the counterweights. This catalog stops that.

3 Machine Groups Covered for Every Assembly

Each illustration page lists machine groups at the bottom: CONTRACTOR 150T, FASTRAC 125, FASTRAC 135T, FASTRAC 145T, FASTRAC 155T — and often FASTRAC 185Ti and FASTRAC-155T with a hyphen. That means one catalog covers seven variants (counting hyphens separately) but the core models are the five you see in the title. The part numbers are cross-referenced to each machine group so you know if a part applies to all or only specific serial numbers. The catalog doesn’t assume; it tells you usage codes when applicable (like “NORTH AMERICA ONLY” for drawbar items 5B and 5C on page 5).

How to Use This Catalog on the Bench

Flip to the assembly you need (use the table of contents or search the PDF for assembly name). Find your machine group and check the serial number range. Write down the part number and change code. Then call your dealer or order direct. That’s it. Do not order a part because the picture looks right. Use the part number from the catalog. If the manual says “Superseded” next to a part number, cross-reference the new number. For example, part 476/80102 (frame) is superseded by 477/00665. That kind of info saves you a return.
