Frequently Asked Questions
Q: What is the difference between the SU S654-A1 and the SU S654-A assembly?
A: The SU S654-A1 and SU S654-A share identical dimensions (5 x 3.625 inches) and material (Cushothane XL). The A1 variant indicates a specific bearing configuration or mounting specification. Verify your truck model number to confirm whether it requires the S654-A or S654-A1. Installing the wrong variant causes fitment issues.
Q: What are the specifications for the SU S654-A1?
A: The SU S654-A1 has a 5.000 inch outside diameter and 3.625 inch width (127.00mm x 92.07mm). Inside diameter is 2.188 inches. Bore outside diameter is 2.4384 inches with a 0.67 inch bore depth. Material is Cushothane XL with a 3/8 inch radius tread profile.
Q: How do I determine if my truck needs the SU S654-A or the SU S654-A1?
A: Check your truck model documentation or contact the manufacturer for the correct wheel assembly SKU. Both variants fit a 5 x 3.625 inch bore size, but the A1 designation indicates a specific mounting design or bearing type optimized for certain truck models. Installing the wrong variant may cause misalignment or premature bearing failure.
Q: Is the SU S654-A1 a direct replacement for an OEM wheel assembly?
A: The SU S654-A1 is a direct manufacturer replacement part for compatible electric lift truck models. Verify compatibility by checking your truck serial number range and comparing bearing bore sizes. The assembly is plug-and-play for trucks originally equipped with a 5 x 3.625 inch assembly. Retrofitting to a different wheel width requires chassis modification.
Q: What tools and time are required to install the SU S654-A1 assembly?
A: Installation requires 30 to 60 minutes with basic tools: socket wrench set, jack, and possibly a bearing puller. Lift the truck, unbolt the old assembly, remove it from the axle, install the new SU S654-A1, and torque bolts to the truck manufacturer specification (typically 35 to 50 foot-pounds). No cutting or welding is needed for trucks designed for this assembly size.
Q: What symptoms indicate the SU S654-A1 assembly needs replacement?
A: Replace the assembly if the truck pulls to one side, if you hear grinding or squealing from the wheel, if the wheel has flat spots or tread chunks missing, or if the bearing has excessive play when you rock the wheel side-to-side. Do not operate a truck with a damaged or failing wheel assembly; it compromises load safety and damages the axle.
