Case 445 Parts Catalog – Factory OEM Parts Breakdown for Skid Steer Loader

I’ve been turning wrenches since before some of you were born, and I’ve seen more bad parts orders than I care to count. A guy calls me from his shop, holding a part that doesn’t fit, blaming the manufacturer. Nine times out of ten, he used a cross-reference from some aftermarket site that guessed the number. This Case 445 Parts Catalog is the factory document. It’s 376 pages of original diagrams and part numbers. No guesses. No third-party interpretations. If you’re working on a Case 445 skid steer loader and you need a radiator fan or coolant reservoir, this is the list you use. Period.

Radiator and Coolant Recovery System – Section 02-01

The first major section in the catalog covers the cooling system. You get exploded views with reference numbers that tie directly to the table of part numbers, descriptions, and quantities. For example, the radiator assembly (Ref 1, Part 87013856) includes the drain fitting and cap as individual items. The coolant recovery reservoir (87020980) comes with a cap and plug. If you need to replace the upper radiator hose, the part number is 87040170, and the clamp specs are right there. This is not a repair procedure; it’s the parts breakdown. But without it, you’re ordering blind.

Fan and Fan Belt Assembly – Section 02-02

Moving to the fan section, you’ll see two fan options: a 480 mm fan (87025470) and a 518 mm fan (238344A1). The catalog notes which one was used depending on production date. The shroud assembly changes accordingly. If you need the V-belt for the fan drive, it’s part 86982450. The exploded diagram shows the spacer, bolts, washers, and the guard. Every fastener has a size and grade – note that the carriage bolts are 3/8″-16 x 3/4″, Grade 5. That matters when you’re sourcing hardware locally. The catalog doesn’t leave you guessing.

Case 445 Parts Catalog – Inside the 376-Page Document

This isn’t a repair manual. If you need torque specs and step-by-step overhaul procedures, get the Case 445, 435 2004 Repair Manual – 912 Pages OEM Factory Specs. But if you’re ordering parts, this catalog is the source. It covers the entire machine: engine, hydraulics, drivetrain, electrical, frame, cab, and attachments. Every section has an exploded diagram with part numbers exactly as Case intended. You can verify superseded parts and find replacement numbers. For example, the lower radiator frame originally was 87436062, but it’s replaced by 87393454 – the catalog notes that. That kind of info saves you ordering a discontinued part.

What Makes This Parts Catalog Different from an Online Parts Lookup?

Online parts lookups are convenient, but they often pull from generic databases that haven’t been updated. I’ve caught mistakes in aftermarket catalogs where the diagram shows the wrong bolt pattern. This manual is a direct scan of the original Case publication. It retains the exact layout, part number tables, and revision notes. You’re not relying on someone who retyped the data. If you’re serious about keeping your 445 running, you need the original. For operators manuals, see Case 445, 435 2007 Operators Manual – Factory Specs Inside for operating procedures and maintenance schedules. The format standards come from the Automotive Industry Overview, but this manual adheres to Case’s specific requirements.

3 Things to Check Before Ordering a Part

First, verify the production date of your machine. The catalog is valid for 445 skid steers built from 3/04 onward. If yours is older, you may need a different catalog. Second, always cross-check the reference number against the description. The catalog sometimes lists “If Used” next to a part – that means it was a running change. Third, check for supersessions listed in the parts table. The lower radiator frame example above is a good case. Failing to check these three things will get you a wrong part every time. For later models, the Case 445, 435, 445CT 2008 Operators Manual – Factory Specs covers the CT version.

Supersessions and Revisions – How the Manual Handles Them

In the radiator section, you see that the upper radiator frame (Ref 3, 87459340) replaces 87024337, with a note that component parts are not serviced separately. That’s a typical supersession. The catalog lists the new part number and often the old one for cross-reference. If you’re ordering, use the latest part number. The manual also indicates running changes with the phrase “If Used” next to the part reference. For example, the fan section shows two different fan assemblies depending on the build. You need to physically check your machine to match the diagram. The Automotive Industry Overview has background on how these standards are developed, but the manual is your specific reference.

Frequently Asked Questions

Is this a repair manual with step-by-step instructions?

No. It is a parts catalog for ordering correct components.

Does it cover the Case 445 after production updates?

Yes. The catalog covers machines built from 3/04 onward. Running changes are noted with ‘If Used’ or supersession part numbers. For instance, the fan section shows two different fan and shroud combinations depending on build date. You need to inspect your machine to see which fan diameter you have (480mm or 518mm) and use the corresponding part numbers. The catalog doesn’t guess; it tells you exactly what was used when. If you ignore these notes, you’ll likely order the wrong shroud or belt. Always verify against the exploded diagram, and confirm your serial number range if possible. The radiator section also shows a supersession for the lower frame, where the original number 87436062 is replaced by 87393454. Using the old part number could result in a backordered or discontinued item. This catalog saves that headache.

Can I use this to look up torque specs?

No torque specs here. This is strictly parts identification. For torque values and procedures, you need the repair manual. We carry that separately.

How do I know if a part number is still available?

Check the latest Case parts network with the part number from this catalog. Many numbers remain active.
