Case 500 Load King Parts Catalog

You pull the serial number off a Case 500 Load King that rolled into the bay. The owner says the radiator is leaking and needs a replacement. He hands you a generic aftermarket lookup from some online forum. You toss it aside. For a loader that old, you need the Parts Catalog, not guesswork. This factory document from Case runs 178 pages and tells you exactly which water pump, belt, and fan assembly fits your specific unit. I’ve spent enough hours chasing wrong parts to know that using anything but the OEM catalog is asking for a comeback. Let me walk you through what this manual actually covers so you don’t waste a Saturday ordering the wrong thermostat housing.

Engine Section Breakdown

The engine section is split into diesel and gas variants. Inside, you’ll find every major component listed by figure number and page. Camshaft and bushings show up on page 33B. Connecting rods and bearings on page 41. Crankshaft and bearings on page 39. The cylinder block spans pages 35-37. Cylinder head and cover: page 33. If you’re rebuilding the top end or pulling the crank, these pages give you the factory part numbers. No cross-referencing with three different websites. No squinting at blurry scanned images from a third party. This is Case’s own numbering system. Order a gasket kit from page 45 and you know the head gasket matches the sleeve configuration.

Cooling System Parts: Radiator, Thermostat, Water Pump

Cooling section runs from page 29. Radiator figure 5, thermostat figure 5, water pump, belt, and fan all on the same page. That’s important because when you pull the radiator on a 500 Load King, you might as well replace the belt and check the water pump while the front end is open. The manual groups these together so you don’t forget. If the thermostat housing is cracked, the manifold heater section (page 53F and 55) may also apply to your engine. I’ve seen guys skip the thermostat because they didn’t realize it was listed right next to the water pump. Page 29 spells it out plain.

Air Intake & Exhaust: Why You Need the Right Air Cleaner

Air intake and exhaust section starts on page 31. Air cleaner, exhaust pipe, manifolds, muffler – all figure 7. The 500 Load King uses a specific air cleaner element. Aftermarket parts catalogs often list a generic can that won’t seal. Page 31 gives you the Case part number. If you’re swapping exhaust manifolds, the gasket and heat shield numbers are there. Don’t trust a reprint that might have swapped illustrations. Stick with the OEM scan. The alphabetical index at the front of the manual gets you to any component fast. I keep a bookmark on that index page because it saves 10 minutes every lookup.

Why OEM Factory Parts Catalog Beats Aftermarket

Aftermarket parts catalogs are notorious for listing superseded parts that don’t fit. I’ve had a cross-reference tell me a bearing set for a 500 Load King was the same as a 580 backhoe. It wasn’t. The Case factory catalog includes serial number breakouts – you’ll see them in the description column of every page. Page 3 of this manual shows the engine serial number, loader serial number, and transmission serial number locations. If your loader falls between two serial number ranges, the part number changes. The aftermarket catalog won’t catch that. This document will. Case CX160B 2007 Parts Catalog – OEM Undercarriage Hydraulics is another example of how Case organizes their OEM data. You get the same level of accuracy for these older machines.

3 Ways the Alphabetical Index Saves Time

First, you don’t need to flip through every section. Look up “Governor” – it points to page 43. Second, the index covers both diesel and gas components together. Third, it lists figure numbers alongside page numbers so you can confirm the illustration matches before you order. Flywheel and housing – page 39. Cylinder sleeves – page 41. Gasket kits – page 45. If you know the assembly name, you find the page in under 30 seconds. That’s the difference between a Parts Catalog that works and a generic parts list that makes you hunt.

Does This Manual Cover the Entire Loader?

Yes, but it’s strictly a Parts Catalog – not a service manual. That means it focuses on part numbers, illustrations, and exploded views. You won’t find torque specs or adjustment procedures here. If you need repair instructions, you want the service manual. But for ordering the correct cylinder block (page 35) or water pump belt, this is the only source you should trust. The 500 Load King is old enough that many parts are discontinued. When you do find a NOS part, you need the OEM number to verify it. Amazon listings with “fits Case 500 Load King” mean nothing. The page 29 cooling section shows the exact belt length and water pump gasket. Case CX27B 2007 Parts Catalog – OEM Factory Specs for Mini Excavator shows how Case maintains this consistency across models.

Why Serial Numbers Matter in This Catalog

Every parts catalog user makes the mistake of ignoring serial numbers at least once. Page 2 and 3 of this manual illustrate where to find engine, loader, and transmission serial numbers on the actual machine. I’ve seen a shop order a connecting rod set for a 500 Load King that turned out to be from a later production run with a different crank pin size. The rod bearing part number changed at serial number 150001. The catalog lists that in the description column. If you skip that step, you end up with a bearing that spins. Case CX40B 2010 Parts Catalog – OEM Factory Spec Data has the same serial number structure – once you get used to reading one, you can read them all.

Frequently Asked Questions

Can I use this Parts Catalog to rebuild the engine?

No. This catalog lists part numbers and illustrations only. You need the service manual for overhaul procedures.

How do I tell if my loader serial number matches the parts pages?

Look at the description column on any page – for example, under “Cylinder Head & Cover” on page 33, the text will note the serial number range. If your loader is VIN number 200001 and above, you order the head gasket listed for that range. The catalog covers all early and late production 500 Load Kings, but you must read the fine print. I’ve had to explain this to three techs this month alone. The serial number breakout is the difference between a part that fits and a part that goes back on the truck. Page 3 shows the exact locations on the machine for engine, loader, and transmission serial plates. Take a photo before you order.
