Case 921E Tier 3 Wheel Loader Parts Catalog (87659898ML)

A 921E Tier 3 wheel loader spends its life in quarries, stockpiles, and load-out yards, moving rock, aggregate, and bulk material all day. This parts catalog is what I pull up when I need to positively ID components before ordering, especially on suspension, axles, and frame hardware. If a loader comes in with a cracked carriage mount or a leaking axle seal, I use this book to trace how the assemblies stack together, pick the right revision of the part, and make sure I’m not missing shims, O-rings, or special fasteners.

Applications & Use Cases

• Cross-checking axle, hub, and wheel component breakdowns to confirm correct seal and bearing sets.
• Verifying which carriage or frame brackets match your serial range before ordering.
• Identifying small hardware, spacers, and bushings that get damaged during teardown and must be replaced.
• Comparing alternate versions of shafts or supports when mid-series design changes exist.
• Printing specific exploded views to keep at the bench while you lay out and tag removed parts.

FAQ

Q: Can I use this catalog on a tablet in the yard or shop?

A: Yes, it’s well-suited to digital use so you can zoom in on exploded views and part callouts next to the machine.

Q: Is this useful if I only need a couple of wear parts?

A: It is, because you can verify the exact variant and any related seals or hardware to avoid multiple trips and mis-orders.

Safety Note

Always verify parts against the machine serial plate and follow Case service safety procedures when working on the loader.
