Case 1845, 1845S 1982 Parts Catalog

If you have a case 1845 or 1845S Uni-Loader sitting in your shop with a busted part and you are stuck guessing which number to order, stop. That guesswork costs you two things: time and cash. I have wasted more hours than I care to admit waiting on the wrong hydraulic hose or the wrong gasket because someone used an aftermarket cross-reference. This Case 1845, 1845S 1982 Parts Catalog is the factory-issued document that parts counter guys use when they actually give a damn. It is 50 pages of exploded views and part numbers straight from JI Case, printed February 1982 in the USA. Not a third-party PDF cobbled from photocopies. Not a reprint. This is the genuine OEM Parts Catalog.

Parts Breakdown: 50 Pages of Factory Figure Listings

Open the catalog and you see a serial number location section on page 2. That is your first stop. Then the figure listings start: engine mounting, flywheel guard, radiator and hoses – both before and after specific tractor serial breaks. The OCR excerpt shows figure numbers for every system: 010 engine mounting, 012 radiator before, 014 radiator after. You get separate listings for gasoline spark ignition (159 engine) and diesel (188 engine). That means you can pin down the exact part for a 1845 gas versus a 1845S diesel without flipping through five different books. Each figure has its own page range with callouts for carburetors, injection pumps, governors, alternators, starters – all the high-wear items that kill your uptime.

3 Reasons to Use OEM Parts Catalog Instead of Aftermarket Lookups

First, supersession history. This catalog includes a revision record log on page 1. Case updated parts over the production run; the revision log tells you which figure supercedes an older one. Aftermarket catalogs rarely track that. Second, you get the actual JI Case part number, not some “equivalent” that fits three models badly. Third, the figure drawings show stack-up order – which washer goes where, which seal orientation. That alone saves you from tearing something apart twice because a bearing retainer was flipped.

Does This Manual Cover Both Gas and Diesel Models?

Yes. Look at the figure list: 028 manifolds (159 spark ignition) and 060 intake manifold (188 diesel). Carburetor sections for gas, injection pump and nozzle sections for diesel. The catalog splits the electrical system too: starter alternator pages for both engine types. If you need the cold start aid (figure 026), that is covered. If you need the induction discharge system (figure 126), it is there. The only thing you do not get is a service procedure – this is a parts catalog, not a repair manual. But if you need the right part number to order, this is the final word.

Find the Right Part: Understanding the Figure Listings

Every figure has a number like 010, 012, 014. Those correspond to a page in the catalog. You look up the figure number that matches your machine’s serial number. For example, engine mounting for 1845 models before a certain serial break is figure 010. After that break it might be figure 012. The catalog tells you which serial range applies. Then you read the callout numbers on the illustration and cross-reference to the part number list. Page 1 has the revision log – check that first to make sure your figure is the current version. That is the workflow I use every time I touch a Uni-Loader.

Source Authenticity: Original OEM Print, Not a Digital Copy

This is the real deal. Issued by JI Case, a Tenneco Company, in February 1982. Printed in the USA. Part number 790258B. The note on page 1 says “Discard Parts Catalog E1277” – that is an official supersession instruction. Aftermarket houses do not print that. They also do not give you the original factory figure layout with the correct bolt callout orientation. If you have ever wrestled with a low-quality scan where the torque specs are illegible, you understand why the OEM print matters. For context on why OEM documentation saves you money, you can read the Automotive Industry Overview and see how standardized parts data prevents misdiagnosis – but really, nothing beats the original sheet.

Frequently Asked Questions

Can I use this catalog to find service procedures like torque specs?

No. This is a parts catalog, not a service manual. It lists part numbers and shows exploded views. For torque values you need the factory service manual.

How do I know which figure applies to my machine’s serial number?

Check the serial number location and production range section on page 2. The figure listing notes “Used Before” and “Used On Tractor” serial ranges. Match your machine’s serial number to the appropriate figure number, then order from the parts list on that page.

Does the catalog include the 1845S model with the 188 diesel engine?

Yes. The figure list covers both 159 spark ignition (gas) and 188 diesel. Sections for injection pump, injector nozzles, diesel fuel lines, and the diesel-specific starter and alternator are all present. The 1845S is fully supported.

Is this a high-quality digital copy or a faded scan?

You are buying the original OEM file as issued by Case – not a scan from a well-used library copy. The file is clear, the part numbers are legible, and the revision log is intact. It is a true factory print.
