Case 921C Loader Parts Catalog (7-4582)

A 921C loader usually lives in quarry piles, truck loading, and waste work, so it sees a lot of abuse in the frame, axles, and wheels. This parts catalog is what I’d pull when I need to pin down exactly which hardware, seals, and housings belong on your machine before I order anything. For example, if you bend a wheel end or crack a mounting support, this book lets me trace every related component in that assembly so I don’t miss a spacer, O-ring, or special fastener that will stall the repair.

Applications & Use Cases

• Confirm correct assemblies when replacing axle, frame, or wheel components after impact damage or heavy wear.
• Cross-check sub-assemblies so the prop shaft, supports, and swivel joints all match your loader’s specific build.
• Identify small parts like shims, bushings, and seals that don’t show well in photos or generic listings.
• Compare revisions of similar parts to avoid ordering an older or incompatible design.
• Plan stock orders by grouping related wear parts for the main frame, wheel equipment, and fluid containers.

FAQ

Q: Can I use this catalog on a tablet in the field?

A: Yes, it’s practical to zoom into the exploded views on a tablet, which helps you verify parts right at the machine.

Q: Is it worth printing pages from this catalog?

A: Many techs print only the assemblies they’re working on, then mark and oil-stain them in the shop without worrying about the original.

Safety Note

Always verify parts visually on the machine and follow the official service procedures before disassembly or installation.
