Develon HW100A Wheeled Excavator Shop Manual (950106-03091_A_EN)

On a wheeled excavator like the Develon HW100A, you’re usually working street jobs, tight sites, utility trenches, and yard loading—lots of pavement, curbs, and close quarters. This shop manual’s for when you’re going past filters and grease and getting into real teardown work: swing gear, boom foot, hubs, steering, valve blocks. Say your swing’s got play and a nasty clunk; this is what you’d use to plan the strip-down, trace the wear, inspect the bearings and shims, then reassemble it without guessing where that thin shim stack goes.

Applications & Use Cases

• Plan a major teardown of the upper or undercarriage so you can lay out parts, route hoses cleanly, and avoid mixing up hardware.
• Trace and isolate hydraulic issues by following the proper sequence to remove, test, and refit pumps, motors, and control valves.
• Check and verify torque sequences on boom, axle, and frame joints so you don’t warp housings or pinch bearings during reassembly.
• Inspect internal components—bushings, seals, gears—while it’s apart, so you only do the job once instead of tearing it back down.
• Align steering, axles, and swing components on reassembly to prevent odd tire wear, drift, or binding under load.

FAQ

Q: Is this a PDF I can search on my laptop or phone?

A: Yes, it’s typically a searchable PDF, so you can jump to sections by keyword instead of scrolling forever.

Q: Can I print just the pages I need for the jobsite?

A: Usually you can print selected sections, which is handy for greasy teardown work where you don’t want your tablet near the pit.

Safety Note

Always bleed off hydraulic pressure and verify the upper is safely supported before you crack any lines or start pulling pins.
