Grove GMK4100 Crane Parts Catalog (3117109)

On a GMK4100 that spends its life lifting on congested construction sites and plant turnarounds, this parts catalog is what I use to make sure the right hardware shows up the first time. When you’ve got the crane down waiting on a hose block, boom wear pad, or cab switch, this book lets you trace exactly how the assemblies are built and which revision fits your serial range. For example, if a hoist function quits and you find a cracked fitting, this catalog helps you identify the correct block, seals, and mounting hardware so you don’t miss a hidden O-ring or order the wrong style.

Applications & Use Cases

Confirm boom, outrigger, and winch component variants before ordering replacements.
Trace hydraulic and electrical sub-assemblies to spot small fittings, clips, and connectors that are easy to overlook.
Cross-check superseded part numbers when Grove updates components mid-production.
Identify complete hardware sets—spacers, shims, and special fasteners—for proper reassembly.
Plan parts pulls and stocking by seeing which items are shared across multiple systems.

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 to read callouts and part references beside the machine.

Q: Is it worth printing sections of this catalog?

A: Many techs print the diagrams for the area they’re working on so they can mark notes, circle items, and keep it next to the parts bench.

Safety Note

Always verify part numbers against the crane’s identification plates and follow Grove’s official service and safety procedures during any work.
