Fiat-Allis 11-B Parts Catalog – 412 Pages of Factory Documentation

If you’re turning wrenches on a Fiat-Allis 11-B direct drive crawler tractor, you need the right part numbers the first time. I’ve been burned by aftermarket catalogs that list a wrong bearing or a mislabeled seal – that costs you a day of downtime and a trip back to the parts counter. This Fiat-Allis 11-B Parts Catalog is the real deal: factory-issued, 412 pages, covering S/N 16C16001-UP. It’s not a reprint or a third-party compilation. It came out of the same offices that built the machine.

Page 3 of the manual spells out exactly how Fiat-Allis changed their part numbering system in 1974. They dropped the check digit, prefixed a “7” (sometimes with extra zeros), and turned old 6-digit numbers into 8-digit ones. Without that page, you’ll order the wrong part. I’ve seen it happen. That notice alone saves you a headache.

Parts Identification – What You Get in 412 Pages

The manual breaks down every major assembly: engine, transmission, final drives, undercarriage, hydraulic system, and dozer attachments. Each section includes exploded-view diagrams with callouts tied to the official Fiat-Allis part numbers. You won’t find vague descriptions like “bearing, roller” – you get the exact 8-digit number. Need to order a track roller or a seal kit? Flip to the undercarriage section. The parts catalog also lists the quantity required per machine, so you don’t end up with one seal when you need four.

One detail I respect: the manual includes the original form number (70677388) and confirms it’s identical to the first printing plus Supplement No. 1 and all parts bulletins through June 1974. That means you’re getting the most complete version Fiat-Allis released for the 11-B. No missing supplements.

Safety First – Page 2 Is Not Optional

Before you start pulling parts, read the warning on page 2. It says: “Never attempt to clean, oil or adjust a machine while it is in motion.” That sounds obvious, but I’ve seen guys skip it. The manual also warns about hydraulically, mechanically, or cable-controlled equipment – lower the blade or bucket to the ground before servicing. If you need to raise it for access, support it with something solid, not the hydraulic cylinders. This isn’t CYA paperwork; it’s how you keep your fingers.

Fiat-Allis printed this safety notice in 1971, but it’s still the standard. Ignore it and you’re asking for a trip to the ER. The manual takes safety seriously, and so should you.

3 Reasons to Choose the OEM Parts Catalog Over Aftermarket

First, aftermarket catalogs often re-use old diagrams but swap in generic part numbers that don’t cross-reference correctly. I’ve had a fuel filter that looked right but had different threads. Second, the OEM catalog includes the exact revision history – you can see which part supersedes which. Third, the factory manual gives you the original part number format so you can verify with a dealer. Aftermarket versions skip those details. For the 11-B, which has a production run with multiple updates, you want the source.

How This Manual Fits Into Your Repair Workflow

When you’ve got a machine down, you don’t have time to hunt through random websites. You need a part number, you need a diagram, and you need to know if that part is still available or if it’s been superseded. This 412-page catalog gives you all that. It also includes a list of additional publications available for the 11-B, so you can cross-reference with the service manual if you need torque specs or adjustment procedures.

FAQ – Fiat-Allis 11-B Parts Catalog

Does this manual cover the bulldozer blade attachments?

Yes. The manual includes a section for accessories, specifically dozers. It lists parts for the blade, tilt cylinders, and mounting hardware.

Are the diagrams clear enough to identify parts without a magnifying glass?

The scans in this digital copy are high-resolution – you can zoom in on callouts. The original printed manual used detailed line drawings. I’ve used similar Fiat-Allis parts catalogs for years, and the legibility is better than some newer aftermarket books.

What about engine parts – does it cover the specific engine used in the 11-B?

It covers the complete engine assembly, including cylinder head, block, oil pan, and all internal components. Part numbers for gaskets, seals, and bearings are listed with quantities. If you need a head gasket, you get the Fiat-Allis number, not a generic size.

How do I order parts using the new 8-digit numbering system?

Page 3 of the manual gives the exact conversion formula. For example, part number 667367 becomes 70667367. You can either convert yourself or give the old number to a dealer who can look it up. The manual also lists the original numbers alongside the new ones in the diagrams.

Stop guessing on part numbers and ordering parts twice. Access the Factory Manual for the Fiat-Allis 11-B Parts Catalog and keep your crawler running with the right components. No reprints, no aftermarket confusion – just the OEM data you need on your screen or printed out.
