Frequently Asked Questions
Q: Will GWK-MPW045E-LW fit my Yale MPW045E jack from 2010?
A: Yes. This kit is engineered for Yale MPW045E (B802 series) jacks regardless of production year. The wheel bore, axle size, and bearing configuration remain consistent across the MPW045E model line. Always verify your jack nameplate shows MPW045E or MPW 045 E before ordering to avoid cross-model fitment issues.
Q: What is the difference between GWK-MPW045E-LW and the XL variant?
A: GWK-MPW045E-LW uses 95A Durarun polyurethane wheels. The XL variant (GWK-MPW045E-LW-XL) uses 97A durometer wheels, which are slightly harder and more wear-resistant. The XL is recommended for higher-cycle warehouse operations where wheel degradation is frequent. Both kits mount identically; choose XL if your facility runs 20+ pallet moves per hour or operates on rough concrete.
Q: Do I need to replace the axles and bearings when I install new wheels?
A: Only replace axles and bearings if they show play, rust, or noise during rotation testing. This kit includes new bearings (6203-2RS) and hardened steel axle hardware. If your existing axles are straight and spin freely, reuse them and install the new wheels on the old axles. Inspect for pitting or scoring first. Replacing all three components ensures maximum load life.
Q: What load capacity does this wheel kit support?
A: The wheel kit itself is rated for the full MPW045E jack capacity. Do not exceed the jack nameplate rating (typically 4500 pounds for MPW045E). The 3.25 inch diameter by 4.50 inch wide 95A polyurethane wheels are load-rated for this class. Floor surface affects performance: rough or oily floors reduce effective capacity 10 to 15 percent.
Q: How do I know if these wheels need replacement?
A: Replace wheels when you observe flat spots, visible cracks, permanent deformation, or loss of traction. Pressing your thumbnail into the wheel should leave only temporary impression; permanent indentation means the 95A compound has degraded and wheels must be replaced. Typical service life is 18 to 36 months depending on floor type and cycle frequency.
Q: Does this kit cross-reference to any other part numbers?
A: GWK-MPW045E-LW replaces Yale OEM part 524233481 and is equivalent to GWK-MPW045E-LW-XL (harder durometer only). Do not confuse with GWK-MPW050-LW or GWK-MPW050E-LW, which fit the larger MPW050 and MPW050E models. Verify cross-references on your invoice before installation; wrong wheel diameter will cause improper jack geometry.
