How to Install and Commission WR1 Drive Wheels
Jul. 10, 2026
Overview
WR1 Drive Wheels are drive-wheel components designed for industrial vehicles and automated equipment. The wheel transfers motor torque to the floor so that the equipment can start, stop, and travel. Available product information describes the WR1 series as using a high-strength polyurethane tread. Polyurethane drive wheels are commonly selected for industrial transport equipment because of their abrasion resistance and suitability for repeated operating cycles.
This guide explains how to:
Confirm that the WR1 wheel is suitable for the equipment.
Install the wheel on the drive shaft or hub.
Check alignment and floor contact.
Perform a controlled first-operation test.
Identify common installation and operating problems.
The WR1 Drive Wheel is not a standalone powered device. It must be connected to a compatible motor, gearbox, hub, shaft, bearings, and machine-control system.
Safety warning: Installation and commissioning must be completed by personnel authorized to service industrial vehicles or automated equipment. Disconnect and isolate all power sources before touching the drive assembly.
Prerequisites
Prepare the following before starting.

WR1 Drive Wheel model or part number
WR1 dimensional drawing
Equipment service manual
Motor and gearbox specifications
Maximum machine load
Maximum operating speed
Required wheel diameter and tread width
Shaft or hub dimensions
Key, spline, or locking-device specification
Fastener torque specification
Required wheel contact pressure
Do not estimate mounting torque, shaft tolerance, load capacity, or operating speed. Use the values stated in the WR1 drawing, purchase specification, or equipment manufacturer’s service manual.
Tools and materials
Caliper or micrometer
Torque wrench covering the required torque range
Correct sockets and hex keys
Dial indicator, when runout measurement is required
Approved lifting equipment

Equipment conditions
Confirm that:
The machine is parked on a level, stable surface.
The machine is unloaded unless the service manual specifies otherwise.
The power supply is disconnected.
Stored electrical, hydraulic, pneumatic, and mechanical energy has been released.
The Emergency Stop is engaged.
The machine is supported by rated stands or lifting equipment.
The work area is closed to unauthorized personnel.
Operating Procedure
1. Verify the wheel specification
Compare the WR1 wheel identification and dimensions with the equipment requirements.
Confirm:
Outside diameter
Tread width
Bore diameter
Hub width
Keyway or spline dimensions
Bearing arrangement
Tread material and hardness
Load rating
Maximum speed
Operating-temperature range
Electrical properties, when antistatic or conductive performance is required
Immediate feedback: The part number and all critical dimensions match the approved drawing and equipment specification.
Stop the installation when the bore, keyway, wheel diameter, load rating, or tread specification does not match. A wheel that can physically fit the shaft is not automatically suitable for the machine.
2. Inspect the wheel before installation
Remove the wheel from its packaging and inspect the complete circumference.
Check for:
Cuts or cracks in the tread
Missing tread material
Separation between the tread and wheel center
Dents or deformation
Corrosion on the hub or mounting surface
Damage to the bore, keyway, spline, or bearing seat
Contamination by oil, grease, water, or packaging residue
Rotate any installed bearing by hand. Confirm that it turns smoothly without binding, grinding, or excessive looseness.
Immediate feedback: The tread is continuous, the hub is undamaged, and the bearing or bore rotates smoothly.
Do not install a wheel with visible tread separation, bore damage, deformation, or an incorrectly fitted bearing.
3. Isolate and support the equipment
Activate the machine’s approved lockout procedure.
Select Power Off on the equipment.
Disconnect the main electrical supply.
Apply the required lockout device.
Release stored energy.
Place wheel chocks at the wheels that will remain on the floor.
Raise the machine using approved lifting points.
Install rated mechanical supports.
Attempt to start the machine using the normal control.
Immediate feedback: The machine does not start, and the drive shaft remains stationary.
Do not work beneath equipment supported only by a hydraulic jack, forklift fork, or lifting sling.
4. Remove the existing drive wheel
Mark the original wheel position when the assembly includes spacers, washers, retaining rings, keys, or directional components.
Release the retaining device according to the equipment manual. Depending on the assembly, this may include:
Shaft nut
Retaining bolt
Locking ring
Taper-lock bushing
Key
Splined hub
Clamping hub
Support the wheel before sliding or pressing it from the shaft.
Inspect the removed components. Replace damaged keys, retaining rings, locking elements, bearings, or fasteners rather than transferring them automatically to the new wheel.
Immediate feedback: The shaft and mounting components are exposed without scoring, bending, or thread damage.
5. Clean and measure the mounting surfaces
Clean the shaft, hub face, keyway, spacers, and retaining components.
Measure the shaft and wheel bore at several positions. Compare the readings with the specified fit tolerance.
Check for:
Shaft wear
Burrs
Raised edges around the keyway
Corrosion
Ovality
Taper
Damaged threads
Incorrect spacer thickness
Remove only minor removable contamination. Do not grind, file, drill, heat, or enlarge the WR1 wheel bore unless an approved manufacturing instruction specifically requires that process.
Immediate feedback: The mounting surfaces are clean, and the measured fit is within the specified tolerance.
6. Position the WR1 Drive Wheel
Orient the wheel according to the equipment drawing.
Install the specified key, spline connection, bushing, spacer, or bearing components. Align the wheel bore with the shaft and move the wheel into position using the approved installation method.
Apply force only to the structural mounting area identified in the installation drawing. When installing a bearing-mounted wheel, do not transmit pressing force through the rolling elements.
Do not strike the polyurethane tread with a steel hammer.
Immediate feedback: The wheel reaches its specified axial position without tilting, binding, or damaging the shaft.
A wheel that stops before reaching the specified position indicates an incorrect fit, misaligned key, burr, contamination, or incorrect component arrangement. Do not pull it into position by overtightening the retaining fastener.
7. Secure the wheel
Install the retaining components in the documented order.
Tighten threaded fasteners to the exact value specified by the equipment or hub manufacturer:
Required torque: [insert approved value and unit]
Use a calibrated torque wrench. Apply lubricant or thread-locking compound only when the service procedure requires it because lubrication changes the relationship between tightening torque and clamping force.
Mark the tightened fastener with a torque-verification mark when required by the maintenance system.
Immediate feedback: The torque wrench indicates the specified torque, the retaining device is fully seated, and the wheel has no unintended axial movement.
8. Check wheel alignment and runout
Rotate the wheel manually through at least one complete revolution.
Confirm that:
The wheel does not contact the frame, guard, motor, cable, or adjacent wheel.
The tread runs in the intended travel plane.
The wheel does not visibly move from side to side.
The wheel does not rise and fall excessively.
The hub rotates without binding.
Measure lateral and radial runout with a dial indicator when the equipment specification requires numerical verification.
Record the results:
Lateral runout: [measured value]
Radial runout: [measured value]
Permitted limit: [approved value]
Immediate feedback: Both measurements remain within the equipment manufacturer’s permitted limits.
Excessive runout may indicate contamination behind the mounting face, an incorrectly seated key, a damaged shaft, a distorted hub, or an incorrectly manufactured wheel.
9. Set the drive-wheel contact pressure
Lower the machine according to the service procedure and confirm that the WR1 tread contacts the floor correctly.
For spring-loaded or adjustable drive assemblies, set the wheel contact pressure to the value specified by the machine manufacturer. The wheel must receive enough normal force to transmit driving and braking torque without exceeding its permitted load.
Check that support wheels and load wheels still carry the machine as designed. Do not increase drive-wheel pressure solely to eliminate slipping without first checking load distribution, tread contamination, and floor conditions.
Immediate feedback: The tread makes even contact across its working width, and the drive assembly remains within its specified adjustment range.
10. Reinstall guards and clear the work area
Reinstall every removed guard, cover, fastener, and safety device.
Remove tools, loose components, lifting equipment, and wheel chocks according to the approved sequence.
Confirm that no person remains beneath or inside the machine’s operating zone.
Immediate feedback: All guards are secured, the machine is resting normally, and the travel path is clear.
11. Restore power and check the rotation direction
Restore the power supply while keeping the machine stationary.
Release the Emergency Stop and select the lowest available manual operating speed. Briefly activate Forward.
Observe the wheel rotation from a safe position.
Immediate feedback: The wheel turns in the direction required for forward machine travel and stops when the control is released.
Select Power Off immediately when:
The wheel turns in the wrong direction.
The wheel rubs against another component.
The hub moves on the shaft.
The drive produces grinding, knocking, or scraping sounds.
The wheel accelerates unexpectedly.
Correct motor phasing, wiring, controller configuration, or mechanical orientation according to the machine manual. Do not reverse wiring by trial and error.
12. Perform an unloaded movement test
Select manual or maintenance mode. Operate the machine without a payload at the lowest approved speed.
Perform the following actions:
Drive forward over a short, controlled distance.
Stop using the normal control.
Drive in reverse.
Turn in both permitted directions.
Apply the service brake.
Apply the parking brake, when fitted.
Immediate feedback: The machine starts smoothly, tracks predictably, stops without abnormal vibration, and does not produce wheel slip or unusual noise.
Stop the test when the machine pulls strongly to one side. Possible causes include unequal wheel diameters, incorrect alignment, uneven contact pressure, incorrect motor settings, or resistance in another wheel assembly.
13. Perform a controlled loaded test
Load the machine with a documented test load that does not exceed the permitted commissioning load.
Repeat the forward, reverse, turning, and braking tests at low speed. Increase speed only after the low-speed results are acceptable.
Observe:
Starting traction
Braking traction
Steering response
Tread deformation
Wheel temperature
Motor current, when available
Noise and vibration
Contact with guards or surrounding components
Immediate feedback: The equipment transports and stops the test load without continuous wheel spin, tread damage, abnormal heating, or unstable tracking.
Do not use the machine at full production load until the commissioning results have been accepted.
14. Complete the post-test inspection
Isolate the equipment again before touching the wheel.
Inspect:
Retaining-fastener position
Torque-verification marks
Axial movement
Tread cuts or scuffing
Tread-to-hub bond line
Evidence of rubbing
Abnormal heat
Debris wrapped around the shaft
Oil or grease on the tread
Recheck mounting torque when the approved commissioning procedure requires it.
Record the wheel model, installation date, measured runout, torque value, test load, test speed, and inspection result.
Immediate feedback: No movement, damage, contamination, or abnormal temperature is detected after the test.

Common Problems
The wheel does not fit the shaft
Likely causes
Incorrect wheel or bore size
Incorrect key or spline
Burr on the shaft
Corrosion or contamination
Key misalignment
Incorrect fit tolerance
Action
Remove the wheel and measure the shaft, bore, and key. Compare the measurements with the approved drawing. Do not force the wheel into position or enlarge the bore without authorization.
The wheel rotates in the wrong direction
Likely causes
Motor phases are reversed.
Motor polarity is reversed.
Controller direction settings are incorrect.
The drive assembly was installed in the wrong orientation.
Action
Disconnect power and correct the motor or controller configuration using the equipment wiring diagram. Do not compensate by changing operator controls or travel labels.
The wheel slips during acceleration
Likely causes
Insufficient contact pressure
Oil, grease, water, or dust on the tread
Incorrect load distribution
Excessive acceleration
Incorrect tread specification
Worn or glazed tread
Unsuitable floor surface
Action
Clean the tread and floor, verify machine load distribution, measure contact pressure, and reduce acceleration to the approved value. Do not coat the tread with adhesive or increase pressure beyond the specified limit.
The machine pulls to one side
Likely causes
Unequal left and right wheel diameters
Incorrect wheel alignment
Unequal contact pressure
One wheel is binding.
Different tread materials or wear levels are installed on the same axle.
Motor-controller settings are unequal.
Action
Measure both drive wheels, inspect alignment, compare contact pressure, and check that each wheel rotates freely. Replace drive wheels as a matched set when required by the equipment manufacturer.
The wheel produces vibration
Likely causes
Excessive radial or lateral runout
Debris attached to the tread
Flat spot
Damaged bearing
Loose hub connection
Tread separation
Incorrectly seated key or bushing
Action
Stop the machine and inspect the wheel. Measure runout and check the mounting connection. Replace the wheel when the tread is separated, permanently deformed, or structurally damaged.
The wheel becomes unusually hot
Likely causes
Excessive continuous load
Operating speed above the approved limit
Bearing damage
Brake drag
Incorrect alignment
Excessive tread deformation
Repeated rapid acceleration and braking
Action
Stop operation and allow the assembly to cool. Check the bearing, brake, load, speed, alignment, and duty cycle. Do not cool a hot polyurethane wheel by applying water unless the product documentation explicitly permits it.
The tread wears rapidly
Likely causes
Wheel spin during acceleration
Frequent sharp turning while stationary
Rough or contaminated floor
Overloading
Incorrect wheel hardness
Misalignment
Continuous operation outside the approved duty cycle
Action
Correct the operating conditions before replacing the wheel. A replacement wheel exposed to the same cause will normally develop the same wear pattern.
Should the tread be lubricated?
No. Keep the wheel tread clean and dry. Oil or grease reduces traction and may affect the tread material. Apply lubricant only to locations specifically identified in the equipment maintenance procedure.
Can a damaged polyurethane tread be repaired?
Do not continue operating a wheel with cracks, missing material, exposed wheel-center material, or tread separation. Remove the wheel and request an engineering assessment. Field repair is acceptable only when the manufacturer supplies an approved repair process.
How often should the WR1 wheel be inspected?
Inspect the wheel before production release and at the interval established by the machine’s preventive-maintenance schedule. Increase the inspection frequency when the equipment operates continuously, carries heavy loads, travels over damaged floors, or performs frequent acceleration, braking, and turning.
The inspection must include tread condition, hub security, bearing condition, contamination, unusual heat, noise, vibration, and wheel diameter.
