Frequently Asked Questions
Q: What electric lift truck models does the SU 855-A load wheel assembly fit?
A: The SU 855-A is a universal load wheel assembly used across most electric pallet jacks, walkie stackers, and reach trucks. Verify your equipment model and serial range before ordering to confirm compatibility. Check the original part number on your jack to ensure the bore size and mounting configuration match.
Q: How do I know if my load wheel assembly needs replacement?
A: Replace the assembly if you observe: load wheels that are cracked, flat-spotted, or visibly worn; excessive wobble or play when the jack is stationary; the mast tilts or lists to one side even on level ground; or the jack no longer lifts smoothly or settles under load. Spin the wheels by hand to check for grinding or binding.
Q: What is the typical load capacity of the SU 855-A assembly?
A: Load capacity depends on the specific tire size and wheel material of your assembly. Most load wheels support 3000 to 5000 lbs when properly installed. Do not exceed the rated capacity of your entire jack unit, which is typically stamped on a nameplate on the mast or frame.
Q: Is installation of the SU 855-A plug-and-play or does it require modification?
A: Installation is typically plug-and-play if the bore and axle diameter match your original assembly. You will need a hydraulic floor jack to raise the mast, a socket set, and possibly a rubber mallet to remove the old axle pins and install the new assembly. Support the mast securely during removal. Do not work underneath a suspended mast without proper blocking.
