Clark-hurth EC500 60, EC500 80B Service Manual – Factory OEM

If you’re working on a Clark-hurth EC500 60, EC500 80B Service Manual is what you need – 385 pages of factory procedures that cover everything from safe maintenance to electrical schematics. I’ve seen too many guys guess at torque specs on these trucks and end up with stripped threads. Don’t be that guy. This manual was originally printed for Clark dealers only, so the information inside is what the factory trained their own techs on. It covers both the EC500 60 and EC500 80B models. No aftermarket shortcuts.

Safe Maintenance Procedures from the Factory

Group SA in this manual starts with the rules you have to follow before you even grab a wrench. Safety signs, safe maintenance practices, general shop precautions – it’s all there. The section on lifting, jacking, and blocking covers raising drive wheels, chaining the upright in raised position, and raising the rear or entire truck. If you’ve ever seen a lift truck settle on a poorly blocked frame, you know why this matters. Page 3 tells you exactly which EC500 60 and EC500 80B models are covered, and page 4 has the foreword – worth reading before you start. The manual is 385 pages of factory-written content, not a rewrite by some third party.

Does This Manual Cover Electrical Troubleshooting?

Absolutely. Sections 12, 13, 16, and 17 are dedicated to electrical systems. Battery handling and testing – including how to get maximum life out of the battery, cleaning, charging, and electrolyte checks. Electrical switches for foot and hand brakes, lift and tilt pumps, forward and reverse – all with adjustment specs. The motor sections cover drive motors, hydraulic pump motors, and steering pump motors. You get disassembly, inspection, testing, and assembly procedures. Plus section 17 has the full wiring schematics – standard wiring, accessory wiring, and diagrams for rear accessory and brush wear indicator. I’ve used Clark wiring diagrams before; they don’t miss a wire color or relay. That’s the difference between a repair that fires up and one that smokes.

385 Pages of Factory Specs – What You Get

The periodic service section (PS) is where you’ll spend most of your time. Maintenance schedules, lubrication points with a chart key, and the PM inspection form. The planned maintenance section walks you through visual inspection, functional checks, and a test drive with load – checking lift mechanism, battery compartment, motor SCR controls, and hydraulic compartment. Critical fastener torque checks are covered. The manual doesn’t assume you know the torque for the drive axle bolts; it tells you. Hydraulic fluid and filter change procedures, sump tank breather maintenance, drive axle fluid change, chassis inspection, upright and tilt cylinder lubrication, lift chains – all spelled out. This is the kind of detail that saves you from pulling a transmission because you overtightened a pan bolt.

Battery Handling: The Factory Procedures for Removal and Installation

Section 12 is 100% battery. Removal, maintenance, cleaning, charging, and installation. It includes how to keep battery records and test procedures using a 500‑volt megger or a Simpson 260-6p VOM on the Rx10,000 scale. If you’ve ever had a battery explode from a spark near the vents, you’ll appreciate the safety warnings here. The manual shows you the right way to clean the compartment and what replacement batteries to look for. No guessing – just factory procedures.

Why OEM Documentation Beats Aftermarket

Every time I see a lift truck with a repair that went wrong because someone used a generic manual, I want to hand them this OEM book. Clark wrote this for their own service personnel. It’s 385 pages of verified specs, not condensed or redrawn. The torque values, fluid capacities, wiring diagrams – all match the truck on your shop floor. Aftermarket manuals often skip the safety sections or renumber procedures. This one keeps Clark’s own numbering system (Group.Section.Page) so you can find any procedure fast. If you’re serious about keeping EC500 60 or EC500 80B trucks running, you want the source material the dealer uses.

FAQ

Is this manual for the EC500 60 only?

No, it covers both EC500 60 and EC500 80B models.

Does the manual include wiring diagrams?

Yes. Section 17 contains electrical schematics including standard wiring schematic, accessory wiring, and diagrams for rear accessory and brush wear indicator. The schematics are factory-original, not redrawn by a third party. If you’ve ever dealt with aftermarket wiring diagrams that miss a relay or show wrong colors, you’ll appreciate having the actual Clark diagrams. The manual also covers motor inspection charts and insulation testing procedures using a 500-volt megger or Simpson VOM. This is the kind of detail that separates a working repair from a fire hazard.

If you need to fix it right, access the factory manual. It’s the same 385-page book Clark gave to its dealers. No guesswork, no aftermarket rewrites – just the specs you actually need.
