Fiatallis 161, Pca 1987 Parts Catalog – OEM Factory Specs for the Scraper

You have a Fiatallis 161 scraper (Pca model) on the yard, and the part you need has three different numbers stamped into the metal. Which one is right? The aftermarket cross-reference you found online says one thing, but the local dealer gives you another. That’s the kind of time-wasting headache that gets expensive fast. This Fiatallis 161, Pca 1987 Parts Catalog is the only source that matches the factory build sheet. No interpretations. No guessing. Just the part numbers Fiatallis used when it left the line.

I have been turning wrenches since before this manual was printed. When I need a part for a 1980s Fiatallis, I do not trust a third-party listing. I go straight to the OEM parts catalog because the factory engineers drew the exploded views and wrote the index. This one has 291 pages of exactly that. Page 1 shows the alphabetical index — AIR CLEANER, ALTERNATOR, AXLES, BATTERY — the whole machine laid out so you can find the group number and get to the right illustration without flipping through guesswork.

Alphabetical Index: Your Starting Point

The first page of this catalog gives you an alphabetical index covering every major system. You want AIR CLEANER? Section 1B-18. BRAKES? Multiple sub-groups: CONTROL (PARKING BRAKE) at 1E-15, MASTER CYLINDER at 1E-11/19/22, DISC at 1E-8/9. The index is not vague — it points to the exact section and page number. That alone saves the half-hour of hunting through binders that most DIYers and home-garage guys burn before lunch.

Brakes and Hydraulics: What the 291 Pages Cover

This is a Parts Catalog, not a service manual. You will not get torque specs or rebuild procedures here — for those you want the service manual. What you get is the complete parts breakdown for the brake system, hydraulic cylinders, elevator assembly, scraper ejector, and every line and fitting. Look under HYDRAULIC PIPING: PUMPS at 1H-7/9, VALVES at 1J-13. The advantage over a Chilton-style aftermarket book? Every part number is the Fiatallis OEM number, not a “fits like” substitute. Fiatallis HD-9 1989 Parts Catalog – OEM Factory Specs covers a different model but follows the same factory numbering logic.

3 Reasons to Choose OEM Documentation Over Aftermarket Cross-References

First: aftermarket catalogs often combine multiple model years into one listing, which means parts that changed mid-production get merged incorrectly. Second: the factory catalog uses the exact nomenclature the assembly line used — “CYLINDER, ELEVATOR LIFT” versus “lift cylinder” — so your dealer can read it without a translator. Third: the page reference system (like 1J-12) matches the factory microfiche and digital archives. A home-garage enthusiast ordering from a generic list risks buying the wrong bowl lift cylinder. That mistake costs a full weekend. Fiatallis HD-6A, HD-6AG, HD-6B, HD-6E 1989 Parts Catalog shows that same precision for a different machine.

Engine and Electrical System Coverage in This Catalog

ENGINE ASSEMBLY lives at 1B-8. ALTERNATOR at 2B-20. HOUR METER at 2B-3. BATTERY at 1B-17. The electrical section (2B-3 through 2B-21) covers gauges, lights, horn, and the full wiring harness breakdown. If you are rebuilding a 161 that sat in a field for ten years, you need the correct alternator bracket and the right headlight assembly. This catalog gives you the factory group numbers so you can order from any Fiatallis dealer that still stocks the parts — or cross-reference with confidence on NSN databases if you work in government surplus.

Scraper Body and Elevator: Where the Confusion Starts

The Pca model is a scraper, not a dozer. The elevator system (1J-15), ejector frame (1K-7), bowl hydraulics (1J-4), and spill guard (1K-11) are unique to this machine. A parts manual for a Fiatallis crawler will not list the elevator chain (1J-18) or the ejector cylinder (1K-9). This catalog is specific to the 161 Pca. The difference between a standard bowl lift cylinder and the one on your unit could be a few thousandths of an inch in port location. Fiatallis HD-21 1990 Parts Catalog – Crawler Tractor Parts Manual is for a completely different platform — do not mix them.

Does This Catalog Include Torque Specifications or Repair Procedures?

No. It is a Parts Catalog. That means exploded views, part numbers, quantities, and reference numbers. You still need the factory service manual for torque values, adjustment specs, and assembly order. But without the right part numbers, even the best service manual leaves you stuck waiting for the wrong gasket to arrive. Use this alongside the Automotive Industry Overview context if you are curious about how these machines fit into historical production, but for actual parts ordering, stick to the factory book.

What if I need the part number for a hydraulic pump on my 161 Pca?

Look up HYDRAULIC PIPING, PUMPS in the alphabetical index — section 1H-7/9. The exploded view shows each component with a reference number that correlates to the parts list. If you cannot find it, the index also lists ALTERNATOR under BATTERY (no, that is a joke — alternator is at 2B-20). Read the index carefully; it is alphabetical.

Is this the same as the service manual?

No. This is a parts catalog. Two different books.

If you are wrenching on a 1987 Fiatallis 161 Pca scraper in San Antonio or anywhere else in North America, this is the parts catalog you want on the workbench. The factory documentation stops you from ordering the wrong brake disc (1E-8/9) or chasing a part that was superseded three times. Access the Factory Manual from AutoRepairManuals and keep the 291 pages of OEM part numbers where you can reach them. Automotive Industry Overview has some background on the evolution of these machines, but the catalog itself is what puts the right steel in your hand.
