Description

Clark C20/25/30/33(35)D Forklift Parts Manual – Tier2 and Tier3

The Clark C20/25/30/33(35)D Forklift Parts Manual is the illustrated parts catalog for the C20-33(35)D truck model, published under Part No. 8039006 with QRI No. I-538-10 for the Tier2 build and QRI No. I-580-3 for the Tier3 build. This is a 326-page PDF that serves both emissions tiers of the same truck family, which means one document covers every unit inside the stated serial ranges rather than forcing you to hunt down a separate book for each build.

Inside, the manual is built around exploded assembly drawings. Each drawing carries balloon key numbers, and beneath it sits a bilingual key table listing the key number, the part name in English and Korean, so a component on the illustration can be traced straight to its description. The back of the file carries the complete Parts Number Index for Tier2 (Lot No. 9646) and for Tier3 (Lot No. 9677), where key numbers, part numbers and descriptions are listed together with the machine serial number at which a part number first applies. That last detail is what makes this catalog genuinely usable on a mixed fleet, because it tells you whether the part you are holding was superseded partway through production.

What that structure gives a technician is a complete part-by-part map of the truck. Instead of guessing at a component name or ordering by description over the phone, you open the group that matches the system you are working on, find the exploded view, read the key number off the illustration, and take the part name straight to the index. The index then hands you the part number and the serial number break where it applies. For a machine that was built across two emissions tiers and a long production run, that serial-number column is the difference between ordering the right seal kit once and ordering it twice.

Why the Serial Number and Tier Matter

The C20-33(35)D was produced in two distinct builds. The Tier2 trucks are identified by serial number P232D-1916 & above-9646 KF, and the Tier3 trucks by P232D-0239 & above-9677 KF. Components that look identical on the outside can differ between the two – engine internals, cylinder head and crankshaft groups, fuel injection and fuel line routing, accelerator linkage, cooling and exhaust systems, and a long list of electrical items all have separate Tier2 and Tier3 sections in this catalog.

Because both builds are documented side by side in one file, you can compare the two layouts directly and see exactly where the assemblies diverge. Always confirm the serial number on the truck before ordering, and use the tier that matches – the catalog is laid out so that this check takes seconds.

Options and Attachment Coverage

Options are not tacked on as an afterthought here. The catalog carries dedicated sections for the equipment that turns a base counterbalance truck into a working attachment carrier: side shifters and side shift cylinders, fork positioners, auxiliary valve plumbing in single and double form for quad masts, lift cylinder piping kits, hi-lo and triple stage uprights with their lift chains, enclosed cab assemblies in multiple configurations, suspension and Grammer, Michigan and Woochang seat options, tall load back rests, strobe lights, work lamps, seat operated brake conversion kits, variable relief valve installation, solenoid valve kits and hydraulic pressure gauge kits. If your truck left the line with an attachment, or you are retrofitting one, the parts for that installation are illustrated and indexed the same way as the base machine.

What You Can Do With It

• Identify a component on the truck from an exploded view and confirm its correct name before you order
• Pull the exact part number from the Parts Number Index rather than relying on a description
• Check whether a part number changed during production and which serial number break applies to your machine
• Compare Tier2 and Tier3 assemblies directly where a system was redesigned
• Build a complete parts list for a job – a brake overhaul, a mast rebuild, a cab installation, an attachment fit-up – from a single document
• Verify that the attachment on your truck is a factory-documented option with a traceable parts breakdown
• Confirm fastener, fitting, seal, hose and clamp part numbers instead of matching them by eye at the counter

Getting the part number right the first time is the whole point of a factory parts catalog. A wrong seal, a wrong hose assembly or a bearing shell from the other tier does not just cost the part – it costs the downtime while the machine sits waiting for a second delivery. This manual removes that guesswork by tying every illustration to a keyed table and every key to an indexed part number, with serial number applicability printed alongside.

Delivered as an instant PDF download after checkout. No shipping, no waiting for a printed book to arrive, no region restrictions on where you can use it. Open it on a laptop in the workshop, a tablet beside the machine, or a phone in the parts aisle, zoom into the exploded views as far as you need, and print the pages you want to take with you. Keep it on file and the same copy is there the next time the truck needs work.
