Frequently Asked Questions
Q: What is the difference between the GWK-MPB045VG-LW and the GWK-MPB045VG-LW-XL?
A: The main difference is wheel durometer: the standard LW model uses 95A polyurethane wheels, while the LW-XL variant uses 97A Shore hardness polyurethane wheels. The 97A rating provides higher load capacity and longer wheel life in high-frequency or heavy-load applications. Both fit the same Yale MPB045VG model. Choose 97A if your jack runs heavy routes or operates 8+ hours daily.
Q: Are the 97A wheels harder to roll than the standard 95A wheels?
A: Yes, slightly. The 97A polyurethane compound is stiffer, which increases load-carrying capacity but requires slightly more effort to push the loaded jack. On smooth, level concrete floors the difference is minimal. On uneven floors or outdoor surfaces, 95A wheels roll easier. For warehouse use with smooth floors and heavy loads, 97A is preferred. For frequent short-distance moves, 95A may be more comfortable.
Q: Do I need to change my greasing schedule with 97A wheels?
A: No. Both wheel types use the same lube axle system and greasing interval: every 500 operating hours or monthly. The 97A compound does not change bearing lubrication requirements. Use the same NLGI grade 2 lithium grease and same 2-3 pump application. The harder wheel material increases wear life, not grease needs.
Q: If I currently have 95A wheels on my MPB045VG, can I upgrade to these 97A wheels?
A: Yes. The GWK-MPB045VG-LW-XL kit is a direct bolt-on replacement for the standard LW kit. Axle dimensions and fastener points are identical. No modifications needed. Simply remove the old wheels and install the 97A kit using the same tools and procedure. Your axles and bearings do not need replacement unless they show damage.
Q: What is the maximum load capacity of a Yale MPB045VG with 97A wheels installed?
A: The MPB045VG is rated for 4,500 pounds maximum load capacity regardless of wheel durometer. The 97A wheels are engineered to carry this load without deformation. The difference between 95A and 97A is durability over time, not maximum load. Do not exceed 4,500 pounds; damage to wheels, axles, or frame will result.
