Frequently Asked Questions
Q: What does the XL designation indicate for the YL 524143966-XL?
A: XL signifies heavy-duty specifications. This version features a 97A durometer polyurethane wheel, which is harder and more wear-resistant than standard or SLIM variants. XL is engineered for higher-load applications or more demanding duty cycles in material handling.
Q: Which Yale equipment models does this XL assembly fit?
A: The YL 524143966-XL is compatible with Yale MPB 040 E (B827) and MPW 045 E (B802) electric pallet trucks. This assembly is designed for production units manufactured from December 2005 forward. Verify your equipment serial number and production date to confirm fitment.
Q: What are the specific component part numbers included in this assembly?
A: The assembly includes a riser bracket (YL 524250478 for post-2005 production units) and lubrication fittings (YL 524148462 and YL 95370). The complete assembly also includes sealed bearings, corrosion-resistant axle, pivot pins, spiral pins, and bushings. All components are integrated into one OEM assembly.
Q: Why is 97A durometer important for this heavy-duty version?
A: 97A durometer polyurethane is significantly harder than 95A or standard ratings. Higher durometer resists flat-spotting, edge wear, and deformation under sustained heavy loads. This extends wheel lifespan in continuous-duty applications. However, harder wheels provide less grip on smooth, wet, or oily floors compared to softer compounds.
Q: Are the sealed bearings pre-lubricated?
A: Yes. The assembly includes sealed bearings, which means they are pre-greased and sealed against contamination. The lubrication fittings (YL 524148462 and YL 95370) are provided for periodic maintenance and re-lubrication if needed during the lifespan of the equipment.
Q: What is the difference between the XL and XL-SS versions?
A: Both YL 524143966-XL and YL 524143966-XL-SS reference the same OEM part number (524143966) and provide identical specifications and fitment. The XL-SS may represent an alternative SKU designation or packaging variant. Contact us to confirm which designation matches your procurement requirements.
