Frequently Asked Questions
Q: What are the dimensions and material specifications for the HY 2081796 load wheel assembly?
A: The HY 2081796 measures 3.25 x 4.50 inches with a 95A durometer polyurethane tread. It features sealed precision ball bearings and integrated string guards. The polyurethane compound is rated at 95A hardness for standard warehouse and light industrial applications.
Q: Which Hyster electric pallet truck models does the HY 2081796 fit?
A: This assembly is compatible with Hyster W40Z and W45Z electric pallet trucks. It mounts on riser linkages and works with OEM axles and bearings. For units produced after December 2005, verify your serial range, as the XL version (97A) may be the correct specification.
Q: What part numbers does HY 2081796 replace or supersede?
A: HY 2081796 supersedes HY 2081800 (through November 2005). It is equivalent to HY 2081796-XL (97A version) and HY 4609399 (stainless steel bearing type). The XL and standard versions differ only in polyurethane hardness and bearing material.
Q: What is the difference between HY 2081796 and HY 2081796-XL?
A: The main difference is polyurethane hardness. HY 2081796 uses 95A durometer, while HY 2081796-XL uses 97A durometer. The 97A version provides increased wear resistance and is better suited for continuous use and cold storage environments. Both fit W40Z and W45Z equipment.
Q: How long does the HY 2081796 typically last in service?
A: Load wheel lifespan depends on usage intensity, floor conditions, and maintenance. The 95A polyurethane compound and sealed ball bearings are designed for moderate warehouse duty. Inspect for flat spots, cracking, or bearing noise. Replace if wheels show significant wear or if bearing play is detected at axle rotation.
