Clark SF50-75s D,L and CMP50-75sD,L Forklift Service Manual (SM713)

These Clark SF50–75s and CMP50–75s D/L forklifts spend their lives loading trucks, feeding production lines, and working around docks and yards, so when they’re down, everything backs up. This service manual is what I’d keep open on the bench while tracing a hard-start diesel, chasing an LPG misfire, or sorting a no-move complaint in the powertrain. It walks you through a logical process so you don’t just throw parts at a problem—for example, when a unit won’t lift under load, you can follow the steps to verify the engine, then the transmission, then the hydraulic side in a sane order.

Applications & Use Cases

• Track engine issues on the diesel or LPG units by following a step-by-step diagnostic path before you condemn components.
• Disassemble and reassemble major assemblies with the right sequence so you don’t miss seals, shims, or alignment steps.
• Verify hydraulic performance when lift, tilt, or auxiliary functions are weak, noisy, or jerky.
• Isolate drivetrain faults like slipping, no travel, or vibration by checking linkages, fluids, and internal components methodically.
• Plan safe workshop workflow, from blocking and lifting the truck to routing hoses and wiring back exactly as found.

FAQ

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

A: Yes, it’s practical to keep it open on a tablet or laptop so you can zoom diagrams and search quickly while you work.

Q: Is it worth printing sections of this manual?

A: Printing the specific procedures you’re doing—like an engine tear-down or hydraulic test—makes it easier to mark notes and keep it next to the truck.

Safety Note

Always secure the forklift, relieve stored pressure, and support raised components before you put tools or hands into any system.
