How to Replace Load Wheels

The load wheels of a machine are primarily responsible for carrying the load, and typically carry the braking system making them a vital component of its respective machine, thus making it important to replace load wheels when needed. Depending on the material that your machine drives on will determine what type of material is needed.

Common materials include the following: polyurethane, nylon, steel and rubber. In addition to material type, level of hardness is also a key attribute. With these components comes a difficult decision: which material do I need for MY machinery?

Load Wheels By Brand

Out of convenience, Intella separates them by brand of forklift. We offer load wheels for the following brands: Yale, Clark, Hyster, Toyota, Crown, Raymond, and CAT.

How to Replace a Forklift Master Cylinder

How to replace a forklift master cylinder: Forklift brake systems typically use a master cylinder often mounted beneath the operator floor panel. The master cylinder is vital for your equipment’s brakes. The master cylinder works as a hydraulic pump that puts in brake fluid to convert brake pedal pressure into hydraulic pressure.

Instructions:

To start, remove the floor panels, find the master cylinder and go to work. This tutorial will show the replacement of a master cylinder on a Hyster 5000 pound forklift with a corresponding full video.

Hyster Forklift Serial Number Lookup: Where Do I Find It?

Note: This page is for Hyster forklifts only. To find a serial number for a forklift of a different brand, click here for our other guides.

Direct Way

The most direct way to do a Hyster forklift serial number lookup is to check the nameplate (also called a data tag). This helpful little plate includes lots of various information about your forklift–how much it can lift, how much it weighs, which model it is, and (most importantly) its serial number. On a Hyster forklift, the nameplate looks like the photo on the left and is often found near the dashboard, like in the photo on the right:

Checking the nameplate is the quickest and easiest method of discerning the serial number of your forklift. But what if the nameplate wears down or has fallen off? You’re not out of luck just yet. Sometimes, a forklift’s serial number can be found in its electronic system or physically stamped on its frame. Below is a list of many different models of Hyster forklifts and where their serial numbers can be found.

How much does a forklift weigh?

How much does a forklift weigh? It’s important to know the weight of your forklift when transporting it, driving it on trailers, moving it in an elevator, or using it in multi-story buildings. You don’t want your forklift to drop through the floor, causing thousands of dollars of damage and injuring workers!

The service weight of a forklift is different from its lift capacity.  Service weight refers to the actual weight of the forklift, including its battery and any attachments it has.  The best place to find the service weight of a forklift is on the forklift’s data tag.  Alternatively, you can search forklift manufacturer websites for product specification pages, but the truck’s data tag is typically preferred over this option. In addition, an industry rule of thumb is that the service weight of the forklift will generally be 1.5 to 2 times the lifting capacity of the forklift.  For example, if your forklift can lift 5,000 pounds, generally the weight of the forklift will be somewhere between 7,500 and 10,000 pounds.  But remember, this is simply a rough standard, and manufacturer information or the forklift’s data tag should always be prioritized.

See below for the weight of some of the most common models of the most widely-used forklift brands. The downloadable table lists the weight in pounds of Hyster, Komatsu, Crown, Toyota, Caterpillar, Yale, Clark, and Nissan forklift models. For starters, here are the weights of the most common models from these manufacturers.

blue forklift light

Q: How much does a Hyster H50FT forklift weigh?

A: 8,924 lbs.  (with NL; 3-stage, 189″ mast height)

Q: How much does a Komatsu FG18HT-20 forklift weigh?

A: 6,340 lbs. (2-stage, standard mast)

Q: How much does a Crown 4520-30 forklift weigh?

A: 5,974 lbs. (standard truck w/o battery)

Q: How much does a Toyota 8FGCU25 forklift weigh?

A: 8,000 lbs. (2 stage, 131.5” mast height)

Q: How much does a Caterpillar C5000 forklift weigh?

A:  8,157 lbs. (standard truck, empty)

Q: How much does a Yale GLC050 forklift weigh?

A: 9,016 lbs. (standard estimate)

Q: How much does a Clark CMP25 forklift weigh?

A: 8,254 lbs. (standard)

Hyster W40Z forklift
Hyster W40Z forklift

Are the error codes on your Hyster W40Z or Yale MPB40-E pallet jack confusing you? Keep reading to learn what problems these codes indicate and how you can solve them.

Yale dash display Intella Liftparts forklift parts

Q: How do I read Hyster W40Z or Yale MPB40-E pallet jack codes?

A: Hyster and Yale forklifts use the same control system, so error codes on Hyster forklifts are the same as those on Yale forklifts. These error codes can actually appear in many ways. While they can be communicated with flashes of a red LED bulb on the jack’s controller, this blog will cover the error codes presented on the jack’s dash display. Sometimes, an error code can mean one of many potential issues. In these cases, it may be necessary to use a special handset or PC to determine which of the problems is the cause of the error code.

Having trouble with error codes from another brand? Check out these other helpful links:

Below are interpretations for the following error codes: no LEDs, no alarm, AL66, AL99, AL01, AL02, AL4, AL5, AL6, AL7, AL8, AL10, and AL94.

Let us help you find your code
  • Dash display: no LEDs or LCDs on
    Condition: inoperative
    Cause: B+ and/or B- missing at controller, defective battery charger, or defective battery charger
    Solution: make sure battery is connected, the key switch is on, and the brake override circuit is in the run position; also test your battery charger and motor controller and replace any nonworking parts
  • Dash display: no LEDs or LCDs on
    Condition: forklift functions as normal
    Cause:  open connection between display and controller, defective display, or defective LEDs
    Solution: make sure harnesses are connected at MDI and connector B on controller; test the dash display by connecting a handset to it and testing for communication; test LEDs by disconnecting them, connecting the handset, and testing the handset; replace any nonworking parts
  • Dash display: no LEDs or LCDs on
    Condition: forklift functions as normal
    Cause:  Because this condition is similar to the last, it will take a handset to determine its cause. If the handset displays “NO COMMUNICATION,” the controller is defective.
    Solution: replace controller
  • Dash display: no alarm
    Condition:  traction and hydraulic functions not working
    Cause: improper startup sequence by jack operator
    Solution: check brake switch, accelerator, steer handle, and hydraulic inputs
  • Dash display: AL66
    Condition: hydraulic function not working
    Cause: battery voltage is low or controller voltage calibration is incorrect
    Solution: charge or replace battery; otherwise, use handset to determine the voltage read by the controller and compare it to an actual voltmeter reading; replace controller if the two readings differ by more than 1.5 volts
  • Dash display: AL99
    Condition: traction and hydraulic functions not working
    Cause: incorrect battery selected, damaged battery, or damaged connection to batter
    Solution: check that you have the right voltage for your truck, manually check the voltage of your battery, inspect it for any damage, and check its connecting crimps and cables for damage as well
  • Dash display: AL01
    Condition:  traction and hoist functions not working
    Cause: control card throttle or lift/lower calibration is out of range; control card is damaged or defective
    Solution: use the tester function on a handset to see if either calibration is greater than 1 volt at neutral; replace control card if damaged or defective, which can be checked by seeing if both “forward switch” and “backward switch” are on at the same time when testing
  • Dash display: AL01
    Condition: traction and hoist functions not working
    Cause: incomplete connection between control card and controller; traction reversing switch not connected; damaged or defective tiller card
    Solution: check connections between control card and controller; use a handset to test for operation of traction reversing switch; replace control card if tiller card is damaged
  • Dash display: AL02
    Condition: traction and hydraulic functions not working
    Cause: main contactor tips are welded closed or motor field circuit is broken
    Solution: disconnect power leads at contactor and test for an open circuit; check connections between motor field and controller
  • Dash display: AL4
    Condition: traction and hydraulic functions not working
    Cause: damaged connection to lowering valve; damaged lowering coil or lowering valve cartridge
    Solution: check electrical connection between valve coil and controller; check lowering valve coil for resistance, replace if not approximately 17.7 ohms; replace lowering valve cartridge if necessary
  • Dash display: AL5
    Condition: traction and hydraulic functions not working
    Cause: damaged connection to brake or brake coil damaged
    Solution: check connection between electric brake and controller; check brake coil for resistance in both directions and replace if not between 27.36 and 30.24 ohms
  • Dash display: AL6
    Condition: traction and hydraulic functions not working
    Cause: damaged connection to traction motor; traction motor armature resistance is too low; field wires are loose or damaged; motor field winding is shorted or too low
    Solution: check electrical connection between traction motor, field wires, and controller; check traction motor armature for shorts; check motor field resistance and correct if not between 0.5 and 1.5 ohms; check contactor coil for resistance of 52 ohms
  • Dash display: AL7
    Condition: traction functions reduced below 14°F or above 167°F and not working above 194°F
    Cause: controller temperature is too hot or cold; controller temperature is not calibrated correctly; controller sensor or controller itself is damaged
    Solution: move truck to a warmer or cooler location; use a handset to check that controller temperature matches room temperature (if not, replace controller)
  • Dash display: AL8
    Condition: traction and hydraulic functions not working
    Cause: over current in driven component
    Solution: check main harness for damaged connections to main contactor, brake, and electric valve coils; check contactor, brake, and electric valve coils for correct resistance (52 ohms for contactor, between 27.36 and 30.24 ohms for brake coil, and 17.7 ohms for electric valve coils)
  • Dash display: AL10
    Condition: traction and hydraulic functions not working
    Cause: controller is damaged; damaged wire connection; short circuit in harness; ground between motor windings and chassis; motor field winding is shorted to chassis; field current driver circuit has failed; watchdog hardware circuit is damaged
    Solution: cycle key switch off and on and replace controller if problem not solved; check wire connections at contactor, pump motor, and traction motor; check main harness for shorts; check for grounds or shorts between motor windings and chassis; check motor field resistance (should be about 1.5 ohms); measure voltage between F1 and B- and F2 and B- on field current driver (should be half the voltage between B+ and B-)
  • Dash display: AL94
    Condition: traction and hydraulic functions not working for one minute
    Cause: no fault is occurring – the controller is installing hour meter memory from MDI display if controller has been replaced
    Solution: no solution needed; truck will operate as soon as data transfer is complete

Hyster forklift serial numbers

Q: How do I decode my Hyster forklift serial number?

A: Post-1957 Hyster forklift serial numbers come in four parts and give information about four different things: the design series of the lift, where the lift was manufactured, the sequence of the lift, and the year it was made. See below for an example of how to read a Hyster forklift serial number.

Hyster serial number model Intella Liftparts forklift parts

Part 1: This section should be a combination of letters and numbers. This sequence refers to the design series and model of the lift, according to the table to the right. Click the table for a larger image.

Part 2: This section should be a single letter. It identifies the manufacturing plant of the forklift, as described below.

  • A = Irvine, Scotland
  • B = Craigavon, Northern Ireland
  • D = Danville, IL, USA
  • E = Nijmegen, The Netherlands
  • F = Flemington, NJ, USA
  • G = government contracts
  • L = Lenoir, NC, USA
  • N = Greenville, NC, USA
  • R = OBU, Japan (OBU-SHI, Aichi-Ken, 474 IT)
  • S = Sulligent Mfg Plant; Sulligent, AL, USA
  • T = Masate, Italy
  • V = Berea, KY, USA

Part 3: This section should be a number sequence. It indicates the sequence of manufacture at the manufacturing plant of the lift truck. The numbering of production models for each plant begins at 1501.

Part 4: This last section should be a single letter. It indicates the year that the lift was manufactured. 1957 began with letter A, 1958 being B, 1959 being C, and etc. The full alphabet is used, except for I, O, and Q. Below are some recent years for reference.

Letter = Year the Forklift Was Manufactured (For older models)
A = 1957J = 1965T = 1973B = 1981K = 1989U = 1997C = 2005L = 2013U = 2021
B = 1958K = 1966U = 1974C = 1982L = 1990V = 1998D = 2006M = 2014V = 2022
C = 1959L = 1967V = 1975D = 1983M = 1991W = 1999E = 2007N = 2015W = 2023
D = 1960M = 1968W = 1976E = 1984N = 1992X = 2000F = 2008P = 2016X = 2024
E = 1961N = 1969X = 1977F = 1985P = 1993Y = 2001G = 2009Q = 2017Y = 2025
F = 1962P = 1970Y = 1978G = 1986R = 1994Z = 2002H = 2010R = 2018Z = 2026
G = 1963R = 1971Z = 1979H = 1987S = 1995A = 2003J = 2011S = 2019
H = 1964S = 1972A = 1980J = 1988T = 1996B = 2004K = 2012T = 2020

Check out the image below for REALLY old years.  Remember, if the last digit of your serial number is one of these letters then that’s the age of the forklift.    Remember Hyster re-uses letters every 20 years.

Hyster forklift model numbers

Q: How do I decode my Hyster forklift model number?

Similar to a serial number, Hyster forklift model numbers also have four parts: the type of truck, the truck’s capacity, the design series of the truck, and a further indicator of type for electric truck models.

Part 1: The first part is a single letter. This letter identifies the series of the lift, according to the following list.

  • B = electric walkie/rider
  • C = electric walkie, center control
  • E = electric lift truck: counterbalanced rider, cushion tires
  • H = pneumatic tire lift truck (IC)
  • J = electric lift truck: counterbalanced rider, pneumatic tires
  • N = electric narrow aisle truck
  • R = electric order picker truck
  • S = cushion tire lift truck (IC)
  • T = electric tractor
  • V = very narrow aisle
  • W = electric walkie

Part 2: This section is either a number or a combination of numbers and letters, and it indicates the capacity of the lift truck. If the capacity is in the inch system, multiply the number in the model code by 100. This capacity is in pounds. For example, if this section of the code is “30,” the capacity of the truck is 30 x 100 lbs, or 3,000 lbs.

If the capacity is in the metric system, look at the number within this section. This gives the capacity directly in metric tons.

Part 3: This section is a single letter, and it designates the design series of the truck. The first design used is represented by A, the second by B, the third by C, and so on through the alphabet. The letters D, G, I, and O are not used.

Part 4: Finally, the last section is either a single letter or two letters that indicate further the specific type of an electric truck model. Note that XL and XM describe design concepts and can be disregarded.

  • A = straddle
  • C = center control – standrive
  • H = pneumatic
  • L = low level pallet
  • R = reach
  • R = rear standrive
  • S = short wheelbase
  • S = stepped battery compartment
  • T = high level pallet
  • T = three-wheel
  • DR = double reach
  • MD = man down
  • MU = man up
