Fiatallis HD-6 1990 Parts Catalog – Get the Right Parts the First Time

If you’re wrenching on an HD-6 crawler tractor and you’ve ever ordered a part that didn’t fit, you know the feeling. Wasted time, wasted money, and a machine sitting dead. That’s where this Fiatallis HD-6 1990 Parts Catalog comes in. I’ve been turning wrenches for 28 years, and I can tell you: without the factory parts catalog, you’re guessing. And guessing costs. This is the OEM reprint from 1990, 265 pages of exploded diagrams, part numbers, and the safety warnings that keep you from losing a finger. Let’s dig into what’s inside.

Safety Warnings: What the Factory Expects You to Know

Flip to the first few pages and you’ll see the same safety warnings that appeared in the original 1990 print. The manual reminds you: never clean, oil, or adjust a machine while it’s in motion. That’s basic, but you’d be surprised how many guys skip it. Also warns about hydraulically or cable-controlled equipment – lower it to the ground before servicing. If you need to raise it for access, support it properly. Don’t trust hydraulics alone. That’s page 2 and 3, and it’s not filler. It’s the kind of stuff that keeps you out of the ER.

Parts Breakdown: How This Catalog Is Organized

This isn’t a repair manual – it’s a parts catalog. That means exploded views of every assembly on the HD-6 crawler tractor. Engine, transmission, final drives, undercarriage, hydraulics. Each illustration has callouts with part numbers. You match the number to the list, order from Fiatallis (or your local dealer), and you know it fits. No aftermarket cross-referencing. The catalog is indexed by group, so if you need a cylinder head gasket, you go to the engine section, find the head gasket in the illustration, and the part number is right there. Pages are numbered consecutively – all 265 of them.

OEM vs Aftermarket: Why Factory Specs Matter

I’ve seen aftermarket parts catalogs that claim to cover the HD-6. They get the part number wrong, or the illustration is vague. Then you get a seal that’s a quarter-inch too thick. This catalog is the original Fiatallis document, reprint 10/90. Every part number is the one Fiatallis stamped on the box. If you want to keep your machine running without chasing fitment issues, this is the source. Don’t trust a third-party compilation. The OEM catalog has the factory part numbers, and that’s what you need when you’re ordering from a dealer or online.

Using This Catalog With the HD-6 Crawler Tractor

If you own an HD-6, whether it’s an early model or one of the later production runs, the 1990 catalog covers it. The PDF includes the full index, so you can jump to the assembly you need. I recommend printing the pages for the section you’re working on – keeps grease off your tablet. The exploded views are clear line drawings, not photos, which actually helps – you can see the relationship between parts better. Need the part number for a track roller? Find the undercarriage section. It’s all there.

What You Get: A 265-Page Factory Document

This isn’t a scan of a scan. It’s a clean PDF reprint of the original Fiatallis parts catalog. 265 pages, English, Form 70626026. You can search by part number or description if you have a PDF reader. I’ve used these catalogs for years – when you have the factory number, you eliminate the guesswork. Pair it with a service manual for torque specs and procedures, and you have the full picture.

Is this catalog the same as a service manual?

No. This is a parts catalog. It lists part numbers and exploded views. You still need a service manual for repair procedures and torque specs.

Will this work for the HD-6B or HD-6E models?

The 1990 catalog covers the base HD-6. For variants like HD-6B or HD-6E, see the related catalog for those specific models. The part numbers may differ for certain components like the engine or undercarriage.
