Hyundai HBF 20II, HBF 25II Parts Catalog – OEM Factory Specs

I have rebuilt more forklift drivetrains than I’ve had Texas barbecues, and nothing wastes billable hours like ordering the wrong part. You pull a hydraulic pump, get the replacement, and the mounting ears are off by 3 mm. That’s because you relied on an aftermarket parts list that swapped a superseded number. This Hyundai HBF 20II, HBF 25II Parts Catalog – 163 pages of genuine factory data – kills that guesswork. Every exploded diagram, every part number, every note about standard vs. optional parts comes straight from Hyundai’s engineering department. No translations lost, no generic cross-references. If you’re maintaining a HBF 20II or HBF 25II forklift, this is the only parts book you should trust on the bench.

Exploded Diagrams and Part Number Mapping

Each component group – engine, transmission, hydraulic system, steering axle, mast assembly – gets its own exploded view on the left page. The right page lists every part number, description in both Korean and English, quantity, and serial number applicability. The catalog follows a consistent layout: figure number, item bubble, part number, description, Q’ty, serial range, and remarks. Remarks tell you if a bolt is M12×1.75×60 or if a seal is standard vs. optional (OPT.). That level of detail matters when you’re ordering a rebuild kit for a 20-year-old forklift that’s been through five owners. You get the exact fastener spec, not a guess.

Why OEM Parts Catalog Beats Aftermarket Lists?

Aftermarket parts catalogs often merge model years, drop supersession notes, or skip the “applies to” column. This Hyundai HBF 20II, HBF 25II Parts Catalog shows serial number ranges for every part – example from page 5: 1~ (HBF 20II), (1~) (HBF 25II). That means you can identify which version of a hydraulic valve fits your specific unit. Aftermarket lists will give you one number for both models and hope you return the wrong one. I’ve seen shops order three different water pumps because the cross-reference didn’t capture the casting change. This manual eliminates that waste. If you manage a fleet of HBF 20II and HBF 25II trucks, you need this catalog to keep parts stocked correctly. Related manuals that follow the same factory standard include HYUNDAI HLF20CII HLF25CII HLF30CII Parts Catalog and HYUNDAI HLF15II HLF18II Parts Catalog.

3 Reasons to Trust This Hyundai Parts Catalog

1. Genuine Hyundai Content – Produced by Hyundai Heavy Industries, not a third-party compiler. The Korean text at the front (pages 4-5) explains the numbering system and warns against unauthorized reproduction. That’s factory legal language, not a click-wrap agreement.
2. 163 Pages of Exact Data – No fluff pages, no advertisements. Each page either shows a diagram or the corresponding part list. If you need a part for the HBF 20II, you find it in this book.
3. Bilingual Accuracy – English and Korean descriptions side by side. When the description says “STEERING CYLINDER ASSY” and the remark says “OPT.,” you know which configuration your truck has. No language barrier confusion.

Understand the Part Numbering System

The first page of the catalog explains how to read the table. Column 1 is the item number from the diagram. Column 2 is the part number (e.g., TVH/7777263 appears on page 2). Column 3 is the Korean/English description. Column 4 is quantity per assembly. Column 5 is the serial number range – critical for determining if a part fits your unit. Column 6 is remarks, including thread pitch for bolts, OPT/STD designation, and left/right (R.H./L.H.) orientation from the driver’s seat facing forward. Ignore this column and you’ll order a right-hand step when you need a left-hand. I’ve seen it happen. This catalog gives you that detail upfront.

Hydraulic and Drivetrain Components: What’s Listed

The hydraulic section covers pumps, control valves, lift cylinders, tilt cylinders, and hoses. The drivetrain section lists torque converters, transmission housings, differentials, and axle shafts. Each assembly is broken down to individual seals, bearings, and snap rings. If you’re rebuilding a HBF 25II mast, you can find the lift chain pulley and the shim kit. The catalog also includes mast sections (inner/outer rails, carriages, forks). Electrical parts like switches, solenoids, and alternators have their own group. Because this is a parts catalog, it does not include repair procedures or torque specs – you would need the corresponding service manual for that. But for ordering, this is the foundation.

Who Should Use This Manual?

Shop owners maintaining a fleet of Hyundai forklifts. DIY enthusiasts who bought a used HBF 20II or HBF 25II and want to order genuine replacement parts instead of chancing aftermarket junk. Parts counter staff who need to verify fitment before selling. If you’re a home-garage guy who picked up a HBF 20II at an auction, this catalog tells you exactly which hydraulic filter fits. Don’t trust the cross-reference app on your phone – use the real book. Pair it with HYUNDAI HDF50III HDF70III Parts Catalog if you have larger models in the fleet.

Is this manual in English?

Yes, the catalog is bilingual Korean and English. Part descriptions appear in both languages.

How do I find the exact part number for my HBF 25II?

First, locate your truck’s serial number (stamped on the nameplate). Then turn to the section that covers the assembly you need – for example, the hydraulic section starts around page 60. Find the exploded diagram, identify the part by bubble number, and cross-check the serial range column next to the part number. If the serial number of your truck falls within the range listed (e.g., “(1~)” for HBF 25II), that part number is correct. If you see “1~” without parentheses, it applies only to the HBF 20II. Pay attention to remarks for OPT or STD – if the truck has optional tilt cylinders, the part number may differ from the standard version. If you’re not sure, call Hyundai parts support with the catalog open to avoid ordering a wrong component that costs you a week of downtime.

You need a parts catalog that doesn’t waste your time. 163 pages of Hyundai factory data, organized by assembly, with serial number applicability and bilingual descriptions. That’s what this is. Access the Factory Manual and start ordering the right parts for your HBF 20II or HBF 25II forklift.
