Clark C300 356 Forklift Overhaul Manual (OH381)

These C300 forklifts spend their lives loading trucks, feeding docks, and shuffling pallets around yards and warehouses, so when the engine gets tired you need a clean plan, not guesswork. This overhaul manual walks you through a full strip-down and rebuild of the power unit so you can bring a weak, smoky, hard-starting truck back to reliable service. When you’ve got one that’s lost power, using oil, or knocking under load, this is what you’d keep open on the bench while you measure, inspect, and reassemble.

Applications & Use Cases

• Plan a full engine teardown so you know what to remove, in what order, and what to tag for correct reassembly.
• Inspect wear surfaces on pistons, liners, bearings, and valve gear, and decide what can be reused versus replaced.
• Verify limits and clearances during mock-up, so you can catch alignment and fit issues before final torque-down.
• Trace hard-to-find noises or vibration back to internal components after a previous poor-quality rebuild.
• Double-check reassembly steps to ensure sealing surfaces, timing relationships, and fasteners are correctly set before first start.

FAQ

Q: Can I use this manual on a tablet at the truck?

A: Yes, it works well digitally; you can zoom in on diagrams and keep it open while you work in tight spaces.

Q: Is it worth printing parts of it?

A: Many techs print the key overhaul and spec pages, slip them in plastic sleeves, and keep them right on the cart for greasy jobs.

Safety Note

Always lock out the truck, support all components securely, and follow proper lifting practices before starting any overhaul work.
