Steiger CA, CU 1984 Parts Catalog – What You Actually Need on the Bench

If you’ve ever ordered a part for a Steiger tractor from an aftermarket listing and ended up with the wrong size seal or a bracket that doesn’t line up, you know the drill. That’s time wasted and a machine sitting. I’ve been wrenching 28 years, and I’ve seen more guys burn billable hours chasing parts that don’t exist in the aftermarket world. That’s why the Steiger CA, CU 1984 Parts Catalog is the only thing I trust when I need a real part number for those old industrial tractors.

This is the original OEM booklet – 221 pages, no reprint crap. Steiger Tractor Inc. put this together in 1984, and it replaces the earlier editions 37-101 and 37-101R1. You get eleven major sections: Cab, Electrical, Climate Control, Drive Train, Air System & Brakes, Frame, Fuel, Hydraulics, Decals, Options & Miscellaneous, and a Numerical Index that cross-references every part number to the page. That index alone saves you from flipping through the whole book blind.

Electrical and Fuel: Factory Part Numbers You Can Trust

The Electrical section (page 2 in the PDF) covers starters, alternators, wiring harnesses, and all the bits that tend to get swapped with wrong parts if you rely on a third-party list. The Fuel section is equally critical – injector lines, fuel tanks, filters, and the related hardware. Both sections give you Steiger-specific part numbers, not generic cross-references that might fit a different chassis. When you’re dealing with a CA or CU series, the frame and component layout is specific. Aftermarket catalogs often lump them with other models, which is a fast track to a return trip to the parts counter.

If you need the Operators Manual for the PT225, PT250, PT270, or PT350, check out Steiger PT225, PT250, PT270, PT350 Operators Manual – OEM. That one gives you operation specs and routine service intervals – a good companion to this parts catalog.

What’s Inside – 11 Sections That Matter

Drive Train, Brakes, and Hydraulics are the heavy lifters. You get exploded diagrams with numbered callouts and the exact Steiger part numbers. The Frame section includes brackets, mounting plates, and chassis components. If you’re restoring or repairing a CA or CU, you need those diagrams to see how the whole assembly goes together before you start torquing bolts wrong.

Pages are marked with revision numbers and dates – Steiger supplemented this catalog over the years, so if you get a later production unit, the page may be updated. The foreword tells you to discard older versions because superseding part numbers happen. This is how OEM catalogs work: they give you the current revision, not some scanned reprint from 30 years ago.

Audience Fit: Who Needs This Catalog?

If you’re a shop owner or a DIY guy with a Steiger CA or CU in the yard, this is for you. Professional mechanics will use the Numerical Index to cross a part number in five seconds instead of calling the dealer and waiting on hold. Beginners will benefit from the clear section dividers with black tabs – each major section has its own contents page so you don’t waste time. The orientation is from the operator’s seat facing forward, so left and right are consistent. And if you need fasteners or seals for a different model, the Massey-Harris-Ferguson FF 30 GS 1957 Parts Catalog | OEM Fastener Guide might be useful for those older machines. For modern wear parts, Futura FC200-FC400 Parts Catalog – OEM Wear Parts Specs covers a different line but follows the same OEM numbering logic.

Source Validity: Why OEM Beats Aftermarket Every Time

This is a scan of the actual printed catalog from Steiger Tractor Inc. (Fargo, ND). They listed dealer parts ordering depots in the US, Canada, and Australia – real infrastructure. The wording on page 3 says “This parts catalog replaces all prior editions” and tells you to discard older ones. That’s factory authority. Aftermarket catalogs renumber parts, combine models, and ignore serial number breaks. This catalog marks S/N breaks on applicable pages. If you’re buying a part for a CA series with a specific serial number, the page will tell you which part number fits. No guessing.

For more background on the automotive and heavy equipment industry, the Automotive Industry Overview gives context on how OEM documentation evolved. Another resource is Automotive Industry Overview (same page) – but honestly, the catalog itself tells you everything you need.

FAQ

Does this catalog cover both CA and CU models?

Yes. The cover says CA & CU Series Industrial Tractors. The content pages list sections applicable to both, with serial number breaks where differences occur.

Are the part numbers still valid for buying new parts today?

Some parts have superseded. The catalog is the best starting point – you take the Steiger number and check with your dealer. Engine parts not listed reference Caterpillar or Cummins dealer supply.

What about electrical diagrams? Are there schematics?

The Electrical section is a parts listing, not a service manual. You get part numbers for wiring harnesses, switches, and components, but not wiring diagrams. If you need repair procedures, look for the service manual.

How many pages and what format is the digital file?

221 pages, scanned from the original 1984 loose-leaf catalog. The PDF is readable and searchable, with bookmarks for each major section. The Numerical Index at the back is 38 pages long.
