What This Manual Gives You

Across its nine groups, the CLARK SSX 12/16/18 Straddle Stacker Service Manual delivers the full depth of information a technician needs to keep these trucks running. The General Information and Technical Data sections give you the exact dimensions, weights, axle loadings, tyre sizes, travel and lift speeds, battery specifications and gradeability figures for each of the three models. Group 01 tells you what to lubricate and when, with a full service schedule and lubrication chart so nothing gets missed during planned maintenance.

The drive unit section is particularly detailed — it walks through the GK 10 transmission, motor and brake, showing the power transfer sequence through the helical and hypoid gears, and then takes you through disassembly and reassembly of the motor, brake, drive wheel and pivoted bogie bearing with tightening torques for every critical fastener. The electrical system chapter covers the complete wiring diagram, fuse box, relays, horn, backup alarm, tiller sensor and MDI-CAN dash display, along with full battery care and testing procedures. The motor controls group contains the complete CLARK/ZAPI fault code charts, which alone can save hours of diagnostic time, plus the handset and laptop programming procedures for adjusting acceleration, braking, speed limits and operator profiles.

For the hydraulic system, you get the power pack specifications (JTEKT-HPI, 3.2 kW motor, 5cc/rev pump, 8.5 L fluid capacity), the hydraulic schematic, mounting and hose line installation with torque values, plus a complete spare parts list for the drive motor. Finally, the upright section covers everything from basic visual inspection through to cylinder overhaul, chain replacement and full upright removal — including the shimming and roller clearance checks that keep a stacker lifting smoothly and safely.

Why This Manual Matters

Straddle stackers work in tight warehouse aisles and handle heavy pallets all day. When something goes wrong — a chain stretches, a cylinder drifts, a fault code appears on the dash, or the drive unit starts making noise — guessing at the repair costs time and can cause further damage. This manual gives you the exact torque values, clearance limits, wear thresholds, fault code meanings and step-by-step procedures that CLARK specifies. Whether you are shimming carriage rollers, setting chain tension, rebuilding a lift cylinder, programming a replacement controller, or tracking down an intermittent electrical fault, having the correct procedure on hand means the job gets done right the first time.

The fault code charts in Group 06 and the troubleshooting guides in Group 08 are especially valuable — they map symptoms to causes to remedies so you can diagnose systematically instead of replacing parts until something works. The torque tables, oil specifications, cylinder gland torque values, chain wear percentages and roller clearance targets give you the hard numbers that are not available anywhere else.
