Fiatallis HD-6A, HD-6AG, HD-6B, HD-6E 1989 Parts Catalog

If you’re ordering parts for a Fiatallis HD-6A, HD-6AG, HD-6B, or HD-6E crawler tractor without this catalog, you’re wasting time and money. I’ve spent 28 years under hoods and undercarriages, and nothing beats having the actual factory part numbers in front of you. Aftermarket cross‑reference lists? Half the time they’re wrong. This Fiatallis HD-6A, HD-6AG, HD-6B, HD-6E 1989 Parts Catalog is the original OEM document – 384 pages, Form 70671739, 3rd printing from January 1989. No reprints, no scanned junk from a third‑party. You get the same data the dealer’s parts counter uses.
Safety Warnings on Page 2: Read Before You Wrench
Page 2 of this catalog isn’t just legal filler. It lays out exactly what can kill you if you’re careless around hydraulically or cable‑controlled equipment. The National Safety Council quote right there says it all: “Never attempt to clean, oil or adjust a machine while it is in motion.” That rule alone prevents thousands of injuries a year. Fiatallis also warns that using non‑approved parts voids warranty and can cause failures. I’ve seen dozer blades drop on guys who skipped the part about supporting the equipment properly. Page 2 spells it out – read it before you even open the hood.
Which Serial Numbers Are Covered?
Not every HD‑6 series is the same. Page 3 lists the exact serial number ranges: HD‑6A from S/N 13322‑UP, HD‑6AG from S/N 40M22251‑UP, HD‑6B from S/N 70C22251‑UP, and HD‑6E from S/N 94S22251‑UP. If your machine falls outside those ranges, this catalog won’t match. Check your tractor’s serial plate against these numbers before you order anything. I’ve had guys call me asking why a part doesn’t fit – nine times out of ten they had the wrong catalog.
384 Pages of Factory Parts Data
Every page in this catalog is an exploded view with numbered callouts and the corresponding Fiatallis part number. Need a hydraulic pump seal kit? It’s in there. Cylinder head gasket? Listed with the exact thickness and material spec. The catalog covers the complete tractor – chassis, engine, drivetrain, hydraulics, and accessories. Page 4 even lists additional publications available: separate catalogs for dozer, ripper, injection pump, plus operation and service manuals. You can order those from a Fiat‑Allis dealer using the form numbers given.
Get the Right Part Numbers – Avoid Returns
I can’t count the hours I’ve watched people waste by guessing a part number off a worn casting. This catalog eliminates that. You cross‑reference your machine’s S/N, look up the assembly group, and pull the exact OEM number. No returns, no waiting days for the wrong gasket.

This 1989 Fiatallis HD-6A, HD-6AG, HD-6B, HD-6E Parts Catalog vs. Aftermarket
Aftermarket parts catalogs often reprint old listings or use generic illustrations. That’s useless when you’re trying to identify a specific bearing or seal. This OEM document – original 1989 print – has been scanned page by page, not reconstituted from a database. Every part number is Fiatallis‑approved. The Automotive Industry Overview might tell you how equipment standards evolved, but this catalog tells you exactly what was bolted on at the factory. Automotive Industry Overview is broad; this is specific. That’s the difference between a part that fits and a part that causes a breakdown.
FAQ
- What models are covered in this parts catalog?
- HD-6A, HD-6AG, HD-6B, and HD-6E crawler tractors from Fiatallis, 1989 publication date.
- Does this manual include torque specifications?
- No. This is a parts catalog, not a service manual. It lists part numbers and exploded views. Torque specs are in the separate factory service manual for these models.
- Is this an OEM document?
- Yes. Form 70671739, 3rd printing, January 1989. Original Fiatallis publication. No third‑party reprint.
- How do I use the serial number table on page 3?
- Locate your tractor’s serial number on the manufacturer’s plate (usually on the left side of the engine block or near the operator’s station). Compare it to the ranges listed: HD-6A: 13322-UP, HD-6AG: 40M22251-UP, HD-6B: 70C22251-UP, HD-6E: 94S22251-UP. If your S/N falls within that range, every part number in this catalog applies to your machine. If your S/N is lower, you need an earlier edition. Do not guess – I’ve seen guys order entire undercarriage kits for the wrong series because they skipped this check.
