What This Manual Provides

This Clark TM12-25 service manual is not a thin owner’s booklet. It is a full workshop-level reference that walks a technician through the complete service life of a 36-volt TM-series truck. The planned maintenance section alone covers every routine interval item — from daily operator checklists and the PM report form through critical fastener torque checks, air cleaning procedures and electrical ground tests. Beyond PM, the manual dives into the EV-100 SCR traction control in unusual depth, including sequence-of-operation diagrams, a full troubleshooting symptom chart, SCR/rectifier testing with a VOM, filter block and capacitor checks, thermal protector tests, reactor/choke module checks, card voltage checks and handset function adjustments for the LXT version.

Component-level service coverage is equally thorough. The motor sections show brush inspection, brush spring tension measurement, commutator condition charts and complete disassembly/reassembly for drive motors, steer motors and lift pump motors. The drive axle chapter covers fluid change, axle removal, drive unit disassembly, ring gear and pinion tooth bearing contact pattern reading, backlash measurement, bearing preload setup and shim adjustment. Brake service includes bleeding, caliper overhaul, master cylinder overhaul and parking brake adjustment. Steering coverage spans trunnion bearing preload, wheel bearing adjustment, power steering relief pressure testing, steering cylinder overhaul and power steering pump overhaul. Hydraulic coverage includes relief pressure setting, main valve overhaul, tilt cylinder overhaul and lift pump overhaul. Upright coverage includes lift chain wear measurement, chain lubrication, fork wear inspection with a wear factor chart, upright downdrift testing and upright removal.

Because the manual spans the whole TM series, it covers several motor and drive configurations used across the TM 12 through TM 25 range, with Clark part numbers, torque specifications and service limits called out at the point of use.

Who This Manual Is For

This Clark TM12-25 service manual suits forklift mechanics, fleet maintenance departments, shop foremen, dealer technicians and serious owner-operators who service their own 36-volt TM-series trucks. It is equally useful for training new technicians on the TM platform, preparing for planned maintenance inspections, and diagnosing electrical or hydraulic faults without guessing. Anyone who works on the EV-100 SCR control, the drive axle, brakes, steering, hydraulics or the upright will find the procedures and specifications they need.

Why a Proper Service Manual Matters

Electric lift trucks are dangerous machines when maintained by guesswork. Wrong torque on a counterweight bolt, an incorrectly shimmed drive axle, a misadjusted trunnion bearing, or a wrong relief pressure setting can all lead to component failure, dropped loads or worse. This manual gives the correct procedures, the correct torque values, the correct fluid specifications and the correct diagnostic sequences so the work is done right the first time. It also documents the special tools, test equipment and safety messages that Clark requires, so a technician can prepare properly instead of improvising.
