Description

This Clark C20/25/30/33(35)D forklift parts manual is the illustrated spare-parts catalog for the Yanmar Tier 3 diesel version of Clark’s C-series counterbalance trucks. It covers two production serial lots: P232D-XXXX-9677 KF and P232D-XXXX-9843 CNF. Every section is set out as an exploded view drawing with numbered callouts tied to a part-number list, exactly as the catalog lays it out for ordering replacement components. The manual is bilingual English and Korean and runs 365 pages.

Past the chapter list, the substance of this catalog is the part-by-part breakdown for the C20 through C35D diesel platform. Each major assembly appears as a numbered exploded view — crankcase, gear cover, camshaft, cylinder head, crankshaft, gasket set, cooling package, fuel injection pump and lines, transaxle, transmission case and differential, torque converter housing, control cover, drive axle, brake assemblies, steer axle, hydraulic pump, main control valve, carriage, upright and cab — so every seal, bearing, shim, gasket, fastener and pipe can be identified and ordered individually rather than as a whole assembly. Where a part differs between the two serial ranges, the catalog separates it, which matters when the truck in front of you was built early or late in the production window.

What the Exploded Views Actually Cover

The illustrations are drawn with the level of detail needed to identify a component even when the stamped number is no longer readable. Gasket kits, seal kits, bearing sets, shim packs, roller sets and spring sets appear as their own numbered items. The hydraulic side of the book goes deep — pump, sump, tank, filter, control valve sections (2-spool, 3-spool, 4-spool and push-button variants), tilt cylinder, steer cylinder, lift cylinder, primary and secondary lift, flow control valves, accumulator and every line and fitting between them. The electrical side runs from the alternator internals (diodes, rectifier, brush kit, slip ring frame) and the starter (drive assembly, pinion, brush holder) through to the full harness layout for the instrument panel, cab and main chassis wiring, plus strobe, back-up alarm and combination rear work lamps.

Getting the Right Part the First Time

For anyone maintaining a Clark C20/25/30/33(35)D forklift with the Yanmar Tier 3 engine, guessing at part numbers is expensive and slow. This manual removes the guesswork: open the section, find the callout number on the exploded view, match it to the part list. It works equally for planned work — an engine overhaul, a transaxle teardown, a brake job, a hydraulic valve rebuild, an upright reseal — and for one-off jobs such as a broken tail pipe clamp, a cab door sash, a solenoid valve or a fork positioner cylinder. The serial-specific breakdown means fitment can be confirmed against the exact truck in the bay before the order is placed.
