GWK-MPW050-LW

Frequently Asked Questions

Q: Is GWK-MPW050-LW compatible with Yale MPW050E electric jacks?
A: No. GWK-MPW050-LW is engineered for manual MPW050 jacks. The electric MPW050E model requires GWK-MPW050E-LW, which includes different bearing preload and axle hardness for electric drivetrain compatibility. Using the manual kit on an electric jack may cause wheel slippage or premature bearing wear. Always verify model designation before ordering.

Q: What wheel diameter and width does this kit include?
A: GWK-MPW050-LW includes two 95A polyurethane load wheel assemblies. Wheel diameter is typically 3.25 inches with 4.50 inch width, matching the larger MPW050 jack geometry. The butterscotch finish is standard for this model line. Verify dimensions on your original jack nameplate to confirm fitment before installation.

Q: Do the wheels come pre-assembled with axles and bearings?
A: Yes. This kit includes two complete load wheel assemblies with pre-installed roller bearings (6203-2RS type), steel axles, and OEM fasteners. Components are factory-assembled and ready to mount. Do not disassemble the wheels unless bearing replacement is necessary; improper reassembly can cause misalignment or wheel imbalance.

Q: What is the load capacity rating for these wheels?
A: Load capacity is determined by the MPW050 jack rating, typically 5000 pounds for manual models. The 95A polyurethane wheel compound and bearing configuration support this full capacity. Do not exceed the jack nameplate rating. Performance degrades 10 to 20 percent on wet, oily, or rough concrete surfaces.

Q: Can I use these wheels on an older MPW050 jack?
A: Yes, if the older jack has the same wheel bore spacing and axle diameter. Check that the original wheels are the same physical size (3.25 inch by 4.50 inch). If original equipment differs, the older jack may use a non-standard configuration; order a complete new load wheel kit matched to your serial range rather than mixing generations.
