Case WX170 Wheeled Excavator Parts Catalog (7-8261+R1_int_USN)

On a WX170 that spends its life loading trucks, trenching along roads, and working in tight urban jobsites, this parts catalog is what I grab whenever something bent, leaking, or worn needs replacing. It lets you visually break the excavator down into assemblies so you can match what’s on the machine to the correct Case part numbers. If, for example, you smack a curb and damage a wheel-end or find play in the axle pivot, this book helps you trace every related component, from big housings down to the shims and seals that are easy to overlook.

Applications & Use Cases

• Confirm correct parts when ordering undercarriage, axle, or frame components after impact damage or heavy wear.
• Cross-check wheel system variants so you don’t mix up different rim, tire, or hub configurations on the same machine.
• Identify small hardware—bushings, O-rings, snap rings, and special fasteners—during a teardown so everything goes back together properly.
• Verify sub-assemblies before a major job, making sure you have the full kit of parts on the bench before pulling the machine out of service.
• Compare revisions when the machine has been updated in the field, helping you match newer parts to older setups.

FAQ

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

A: Yes, it’s practical to keep it on a tablet or laptop so you can zoom into exploded views right next to the machine.

Q: Is it worth printing sections of this catalog?

A: Many techs print only the pages for the area they’re rebuilding and keep them in a plastic sleeve at the workbench.
