Hyundai HLF30CII, HLF20CII, HLF25CII Parts Catalog

If you’re hunting down a part number for a Hyundai HLF30CII, HLF20CII, HLF25CII Parts Catalog, you don’t have time to flip through generic diagrams that mix three model years into one. I’ve been wrenching on forklifts since before most of these trucks were built, and I can tell you right now: guessing a bolt size because a third-party catalog used the wrong illustration wastes an afternoon. This 291-page factory Hyundai parts catalog gives you the actual exploded views and part numbers straight from the assembly line. No reprints, no copy. OEM or you’re wasting money.

What This 291-Page Parts Catalog Covers

You get the complete parts breakdown for three models: HLF20CII, HLF25CII, and HLF30CII. Each machine has its own section with exploded diagrams showing every nut, bolt, and seal. The manual groups components by system – engine, transmission, mast, hydraulics, steering, and electrical. Page numbers? I’m not going to list every one, but the power train section runs several pages deep. If you need a part for a specific serial number range, the catalog tells you exactly which revision fits. That’s data you won’t find in a generic parts list. For a direct reference, point your browser to HYUNDAI HLF20 HLF25 HLF30CII Parts Catalog.

Using the Part Numbering System to Avoid Screw-Ups

The foreword (page 2) explains how to read the columns: ITEM, PART NO., IS (engineering change), DESCRIPTION, QTY, SERIAL NO., ITC, and REMARK. Pay attention to the ITC codes. They tell you interchangeability – whether a new part can replace an old one or not. For example, code A means old and new are fully interchangeable. Code D means they’re not – order the correct revision. If you skip this, you’ll end up with a part that doesn’t bolt on.

HLF20CII vs HLF25CII vs HLF30CII: Where They Differ

These trucks share a common chassis but differ in lift capacity and some hydraulic components. The catalog marks differences with a note on the group name. For instance, a mast cylinder on a HLF30CII might have a larger bore than the same assembly on a HLF20CII. The parts list shows separate item numbers and quantities per model. Don’t assume a part from a HLF25CII will swap onto a HLF30CII without checking the serial number column.

How to Order Parts – What the Manual Actually Shows

There’s a dedicated ordering guide in the manual. You’ll need the model name (e.g., HLF20CII), the serial number (stamped on the right side of the frame on top of the hydraulic tank), the part number (with issue number if applicable), part description, and quantity. The manual gives an example: HLF20/25/30CII, serial HC30HG10142, part F23340203, PEDAL ASSY, qty 1. Fill out that info exactly and you’ll get the right part. No surprises.

Why Aftermarket Parts Lists Fail – Stick with OEM

I’ve seen third-party catalogs that list a part number that hasn’t been in production for ten years. They don’t show engineering change flags or serial number breaks. This Hyundai manual does. It’s the same document the dealer uses to order parts for your lift. If you want to avoid returning a wrong cylinder or waiting three days for the correct seal, use the OEM source. For related models, check out HYUNDAI HLF15II HLF18II Parts Catalog and HYUNDAI HDF50III HDF70III Parts Catalog if your equipment matches. The Automotive Industry Overview explains why OEM documentation is preferred. For battery-powered variants, the Automotive Battery section is included as well.

Q: Can I use this catalog for a HLF30CII built in 2005?

A: Check the serial number range listed for each part. The catalog covers specific serial number breaks.

Q: What do the ITC codes A, B, C, D mean?

A: ITC codes indicate interchangeability between old and new part revisions. Code A (Old ⇔ New) means fully interchangeable both ways. Code B (Old ⇒ New) means the new part can replace the old, but not vice versa. Code C (Old ⇠New) means the old can replace the new. Code D means no interchangeability ““ you must use the exact revision specified. This information is critical when ordering replacement parts for a machine that may have had engineering changes during its production run. Always check the ITC column before ordering.

So don’t gamble with aftermarket parts lists. Get the factory data for your HLF20CII, HLF25CII, or HLF30CII. Access the Factory Manual and keep a copy at your workbench. A parts catalog is only useful when it’s accurate ““ this one is.
