Case CX27B Mini Excavators Parts Catalog (7-9594)

A CX27B usually lives in tight jobsites—utility trenches, landscaping, small demolition—where downtime hurts. This parts catalog is what I’d pull out when I need to identify exactly which components belong on your machine before I place an order. Say you’ve got a track roller weeping oil or a cracked boom pin boss; this book lets me trace every related piece in the assembly so I don’t miss the collars, shims, or seals that should be replaced at the same time.

Applications & Use Cases

• Match the correct undercarriage rollers, idlers, and sprockets to your serial range so everything lines up and tracks properly.
• Cross-check pins, bushings, and shims in the boom, arm, and bucket linkage to avoid ordering the wrong size when there are running changes.
• Verify all the frame and mounting hardware when repairing damage from a side impact or bent step/guard.
• Identify hydraulic line brackets, clamps, and fasteners so hoses are routed and secured the way the factory intended.
• Confirm small but critical parts—seals, O-rings, caps, and plugs—that are easy to overlook when rebuilding a sub-assembly.

FAQ

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

A: Yes, it works well on a tablet; you can zoom into the exploded views to read item callouts and part numbers right next to the machine.

Q: Is it worth printing pages from this catalog?

A: Many techs print just the relevant exploded view and parts list, keep it in a job folder, and mark off what’s been replaced or ordered.

Safety Note

Always verify parts with the machine’s serial plate and follow Case’s safety instructions before inspecting or working on any component.
