Hyundai HDF50III, HDF70III Parts Catalog – 359 Pages of Factory Specs

I have torqued more head bolts than most people have had hot meals. When I order a part for a Hyundai HDF50III or HDF70III fork lift, I don’t want a parts list that was typed from a phone photo by someone who’s never held a wrench. That’s why this Hyundai HDF50III, HDF70III Parts Catalog exists. It’s the same binder Hyundai gives their dealers. 359 pages, OEM printed, no reprints. You get the exact part number, the interchange code (A, B, C, or D), and the machine serial number break. That tells you if the new part swaps in without modification or if you need to order the old one. Look at page 2 of the manual – they explain the codes. Old to new, new to old, no guesswork.

Parts Ordering: Hyundai’s Own System

Every group in this manual starts with a clear illustration and a parts list table. Each item number matches the diagram. You see PART NO., DESCRIPTION, QTY, SERIAL NO., ITC interchange code, and REMARK. The description column includes dots to show sub-assemblies – one dot for a component, two dots for a sub-component under that. This is the kind of detail that stops you from ordering a king pin (item 81FF-50200 on the sample page) when all you really need is the bushing that goes inside it. I’ve seen guys order the wrong part because some aftermarket catalog lumped everything under “pin kit.” This manual breaks it out.

Interchange Codes: Why They Matter

If you see “A” in the ITC column, old and new parts swap both ways. “B” means the new part substitutes for the old – you can go forward but not backward. “C” means the old part can substitute for the new (you’re retrofitting). “D” means no interchange at all – buy the correct number. Page 2 of the manual (Korean and English) lays this out. Without these codes, you’re flipping coins with customer time. That matters when a lift is down and the warehouse is stacking pallets on the floor.

What Systems Are Covered in These 359 Pages?

The table of contents (not printed in the sample, but the manual covers the full forklift) includes groups for the engine, transmission, drive axle, steering axle, mast, carriage, hydraulics, brakes, electrical, instrumentation, counterweight, and optional attachments. Each group has its own illustrated parts breakdown. For example, the MCV (Main Control Valve) assembly, O/COOLER, O/FILTER, CYL, BRKT, CWT – all the abbreviations listed on page 3 are used throughout. The manual gives you the part numbers, so you can order from your Hyundai dealer (or any dealer that reads Hyundai part numbers) without calling a hotline.

3 Reasons to Buy This OEM Catalog

1. You get the actual factory part numbers – not a cross-reference that might be wrong for your serial number range.
2. You get interchange codes so you know whether a superseded part works without looking at three forums.
3. You get the exact quantity per machine – no guessing whether you need one or two of a seal.

I’ve seen aftermarket catalogs list the wrong quantity because they copied from a chassis with a different option. This manual has a SERIAL NO. column that tells you exactly which serial numbers use which part. If your HDF50III is serial FF0110001 or above, you need the later version of that part. This manual shows the break point.

How to Use This Manual on the Bench

Flip to the group you need – say the drive axle. The illustration shows the axle housing, differential, hubs, and brakes. Each part has a callout number. The table next to it gives the part number, description, and QTY. If a part is shown but not available, the item column has an asterisk. If it’s a kit component, you see a “K.” Sub-assemblies get an “S.” No confusion. The manual also has a REMARK column for reference pages – like when a bolt is torqued to a spec that’s in the service manual, they’ll tell you which page to check. That’s why you want both the parts catalog and the HYUNDAI HDF50III HDF70III Service Manual sitting next to each other. Parts without torque specs are just expensive paperweights.

Does This Manual Cover the Fuel System?

Yes – the engine group includes fuel injection components, filters, lines, and the battery. The abbreviations on page 3 list E/GASKET (engine gasket), BATT (battery), O/FILTER (oil filter), and RAD (radiator). For battery specifics, you can cross-reference with the Automotive Battery info on Wikipedia to understand BCI groups. But the part numbers in this catalog are Hyundai-specific. For alternative models like the HYUNDAI HLF20CII HLF25CII HLF30CII Parts Catalog or the HYUNDAI HLF15II HLF18II Parts Catalog, those have different part numbering systems because the chassis sizes vary – don’t mix them up.

Who Should Buy This Manual

If you service or own a Hyundai HDF50III or HDF70III forklift – either as a fleet mechanic, a small shop owner, or an equipped owner – you need this catalog. It’s not a repair manual (that’s the service manual), but without the parts catalog you’re ordering blind. If you’re a DIY mechanic working in a warehouse, don’t rely on generic parts lookup sites. Use the factory document. Torque specs and safety warnings? Those are in the service manual. But the parts catalog tells you what to torque onto the machine. The two work together. I’ve got both on my bench. This one saves the phone calls.

FAQ: Questions You’ll Have

Q: Do I get the English version or just the Korean?

A: The manual is bilingual – English and Korean side by side. All part numbers, descriptions, and codes are in English. The how-to-use section and abbreviations are in both languages. You can read it without a translator.

Q: Does this include torque specs?

A: No. This is a parts catalog. Torque values are in the service manual. But the REMARK column does reference service manual pages where applicable. If you need torque, get the service manual.

Q: What do I do if a part is marked “N” (not availability)?

A: Contact your Hyundai after-service center. The catalog tells you it’s not stocked, but the dealer can order it or suggest a supersession using the interchange code.

Q: How do I identify my machine serial number?

A: Located on the right side of the cab frame, stamped into the metal. The manual sample shows the example “FF0110001.” Your number may start differently. Use that number to confirm you’re ordering parts for the correct serial break.

This catalog comes as a PDF format. You get all 359 pages of factory part data, including the abbreviations list, the how-to-use instruction, and every group illustration. No missing pages. No watermarks. You can print the page you need or keep it on a tablet in the shop. I keep mine on a laptop next to the service manual because I’m tired of cleaning grease off paper. Access the Factory Manual and get the right part number on your first order.
