Frequently Asked Questions
Q: Is SU 9109-A a direct replacement for SU 9109?
A: SU 9109-A is a variant assembly that is functionally equivalent to SU 9109 for most electric lift truck models. Both feature polyurethane tread, machined steel hub, and sealed bearings with axle pin mounting. Check your truck serial number range and model documentation before ordering to ensure SU 9109-A is the correct part. If unsure, contact the truck OEM with your serial number.
Q: What is the difference between SU 9109-A and SU 9109-XL-A?
A: SU 9109-A is the standard load wheel assembly. SU 9109-XL-A is the extra-large variant, which has a larger wheel diameter and is used on specific truck models that require higher ground clearance or different gear ratios. Do not substitute one for the other as they will not fit or function correctly. Verify the XL designation matches your truck requirements.
Q: Does SU 9109-A require any special tools for installation?
A: No special tools are required. You need a wrench or pliers to remove and install the cotter pin, and possibly a socket set to remove the axle pin if it is tight. The assembly uses standard axle pin mounting common to electric pallet trucks. Refer to your truck service manual for torque specifications if provided.
Q: Can SU 9109-A be used on both indoor and outdoor electric lift trucks?
A: Yes. SU 9109-A is rated for both indoor and outdoor electric lift truck applications. The polyurethane tread provides good grip on concrete, asphalt, and smooth warehouse floors. However, outdoor use will accelerate tread wear. Inspect the wheel every 6 months if used outdoors regularly, and every 12 months for indoor-only use.
Q: What is the lifespan of SU 9109-A?
A: Expected lifespan is 2 to 4 years under normal warehouse conditions with typical daily use. Lifespan depends on load frequency, floor surface, and maintenance. Indoor use extends lifespan. Heavy use or outdoor operation reduces lifespan to 18 months to 2 years. Replace when tread is worn to less than one-quarter inch or when bearings show signs of failure.
Q: Is SU 9109-A compatible with battery-powered versus manual pallet trucks?
A: SU 9109-A is specifically designed for electric lift truck applications only. It is not rated for manual hydraulic pallet jacks. Attempting to use it on manual equipment will void the warranty and may result in unsafe operation. Confirm your truck is electric powered before ordering this assembly.
