If you've ever ordered a forklift part that didn't fit, there's a good chance the problem started before the order was even placed. Many forklift models look nearly identical from the outside but use completely different engines, transmissions, masts, and electrical systems depending on the production year and serial range. That's why the first question any parts supplier will ask you is: what's your model and serial number?
This guide shows you exactly where to find both — even if your data plate is worn or missing.
Step 1: Check the Data Plate (Nameplate)
Every forklift leaves the factory with a data plate, also called a nameplate or capacity plate. It's a metal tag riveted to the truck, and it's legally required to stay on the machine. It lists the model number, serial number, truck weight, load capacity, mast type, and tire information.
Common data plate locations:
- On the dash near the steering column or hydraulic levers
- Inside the operator compartment on the cowl or side panel
- Near the seat on the fender or hood area
- On the counterweight (some electric and older models)
If the plate is readable, you're done — write down the full model number and serial number exactly as printed, including any dashes and letter prefixes. A model listed as "8FGU25" is not the same as "7FGU25," and one character can mean a completely different parts catalog.
Step 2: If the Plate Is Missing, Find the Frame Stamp
Data plates get painted over, damaged, or removed over the years — especially on used and auction equipment. Fortunately, manufacturers also stamp the serial number directly into the frame. The stamping is usually on a flat, machined surface and may be hidden under paint or grime, so bring a flashlight and a wire brush.
Typical frame stamp locations by brand:
- Toyota: On the frame near the front right side, close to the mast or under the hood on the frame rail
- Hyster / Yale: Stamped on the right-hand frame member, often near the front axle or under the hood
- Crown: On the frame near the power unit compartment (electric models)
- Clark: On the frame under the hood, or on the left frame rail near the operator step
- CAT / Mitsubishi: Front frame area near the mast mount, or on the frame under the floor plate
- Nissan / UniCarriers: Frame rail near the front right wheel or under the hood
- Komatsu: Right side frame near the front, sometimes under the floorboard
- Doosan / Daewoo: Frame rail near the front axle or under the hood on the right side
Exact locations vary by series and production year, so if you don't find it in the first spot, check the other side of the frame and under removable floor plates.
Step 3: Understand What the Numbers Mean
Forklift model numbers are codes, not random characters. Take a Toyota 8FGU25 as an example: the "8" is the series generation, "FG" means it's a gas/LPG engine truck, "U" indicates it was built for the North American market, and "25" means a 2,500 kg (roughly 5,000 lb) capacity class. Hyster and Yale use similar logic — an H50FT is a 5,000 lb pneumatic-tire internal combustion truck.
The serial number then pins down exactly when your truck was built and which parts revision applies. Many manufacturers changed engines mid-series (for example, moving to a different engine supplier partway through production), so two trucks with the same model number can still take different parts. The serial number is what resolves that.
Step 4: Check Component Tags for Major Parts
For engine, transmission, and mast parts, it also helps to record the numbers on the component itself:
- Engine: Look for a tag or stamping on the engine block — common forklift engines like the Nissan K21/K25, Toyota 4Y, Mitsubishi 4G63/4G64, and GM 4.3L each have their own parts systems
- Transmission: Tag on the transmission housing
- Mast: Stamped on the mast rail, usually near the bottom
What to Do With This Information
Once you have the model number, serial number, and (ideally) the engine model, ordering parts becomes fast and accurate. When you contact us or search our store, include all three. For example: "Toyota 8FGU25, serial 12345, 4Y engine — need a water pump." That one line lets us confirm exact fitment before anything ships.
Can't find your serial number, or the frame stamp is unreadable? Send us a few photos of your forklift — the data plate area, the engine bay, and the overall truck — and we'll help you identify it.
