Clark WP40 Palletjack Parts Manual (WP-3, WP-4, WP-5, WP-6, WP-7)

A Clark WP40 pallet jack spends its life shuttling skids around warehouses, loading docks, and trailers, where it takes a lot of abuse and parts get swapped over the years. This parts manual helps you positively identify every component on the WP-3 through WP-7 variants so you’re not guessing at what’s on the handle, mast, or battery area. When you’re chasing an intermittent lift issue or replacing a damaged backrest or battery connector, this book lets you match what’s on the truck to the correct Clark part description before you order or tear deeper into it.

Applications & Use Cases

• Verify which WP40 variant you’re working on so you don’t mix parts between similar-looking units.
• Trace assemblies like the battery pack, lifter, or backrest down to the correct subcomponents during teardown.
• Cross-check old or worn-off markings by comparing the illustrated layouts to what’s actually on the pallet jack.
• Confirm replacement options when a previous owner has installed non-original hardware or wiring.
• Reduce downtime by ordering the right part the first time, instead of trial-and-error with near matches.

FAQ

Q: Can I use this manual on a tablet in the shop?

A: Yes, it’s practical to view digitally so you can zoom in on diagrams while standing next to the truck.

Q: Should I still print pages from it?

A: Printing the pages for the areas you’re working on is handy for quick notes and keeping greasy hands off your device.

Safety Note

Always secure the pallet jack, isolate power, and follow proper lockout practices before inspecting or replacing any parts.
