GW L13

Frequently Asked Questions

Q: What makes GW L13 different from standard 3 inch load wheels?
A: GW L13 is a 2.85 inch diameter wheel, not 3 inch. This smaller diameter is designed for specific manual pallet jack models that require a reduced-height assembly or lower overall mast collapsed height. The 3.75 inch width and complete drop-in assembly design mean GW L13 can be swapped without additional hardware modifications. Do not assume all 2.85 inch wheels are equivalent; always verify the bearing type matches. GW L13 uses precision sealed bearings rated ABEC-1 tolerance for smooth operation up to 5500 lbs load capacity.

Q: Is the GW L13 wheel assembly zinc-plated throughout, and why does that matter?
A: Yes, GW L13 includes zinc-plated axle and washers to resist corrosion in damp warehouse conditions. Zinc plating extends the lifespan of the wheel assembly by preventing rust on critical mounting components. The black polyurethane tread is non-coated, allowing direct contact with the floor for high traction. In wet or coastal environments, zinc-plated hardware reduces maintenance and extends the interval between replacements. Inspect zinc plating annually for white corrosion spots; light corrosion does not affect function, but heavy corrosion indicates high moisture exposure and may require protective oil coating.

Q: How do I diagnose bearing failure in a GW L13 load wheel?
A: Symptoms of a failed GW L13 bearing include squealing noise during jack operation, rough or grinding sensation when spinning the wheel by hand, and irregular lift or descent speed. The wheel may develop side-to-side play if the ABEC-1 sealed bearing is severely degraded. Jog the jack up and down slowly and listen for noise from each wheel; bearing failure in one wheel produces a consistent squeal. Do not operate the jack if bearing failure is suspected; continued use can damage the axle and fork, increasing total repair cost. Replace the entire GW L13 assembly; sealed bearings cannot be serviced separately.

Q: What is the correct installation procedure for the GW L13 drop-in assembly?
A: Lower the jack fully on a level surface and lift the fork clear of the floor. Remove the cotter pin and nut from the existing wheel assembly. Slide the old wheel off the axle. Clean the axle shaft with a wire brush to remove rust and debris. Slide the GW L13 drop-in assembly onto the axle, ensuring the wheel and precision-sealed bearing seat fully. The assembly is pre-aligned, so no adjustment is needed. Reinstall the zinc-plated washer and nut hand-tight, then tighten snug with a wrench. Insert a new cotter pin through the axle hole and bend the prongs outward to lock. Test hand-spin rotation to confirm smooth, free operation before lowering the jack.

Q: What is the expected lifespan of the GW L13 wheel assembly?
A: GW L13 wheels typically last 24 to 48 months in medium-use conditions handling 50 to 100 pallets daily. Heavy daily use or rough handling can reduce lifespan to 12 to 24 months. The ABEC-1 precision sealed bearings are designed for longer life than standard bearings; however, contamination or water intrusion can accelerate wear. Inspect GW L13 wheels monthly for tread loss, bearing noise, or zinc-plating corrosion. Replace wheels as soon as tread loss exceeds 25 percent or bearing roughness is detected. Replace both or all wheels as a set to maintain balanced lift and prevent uneven wear on the mast.
