Frequently Asked Questions
Q: What models does the GWK-JET A/L-LW replace, and are there equivalent part numbers?
A: GWK-JET A/L-LW is the primary SKU for Jet Model L pallet trucks. Cross-reference equivalents are GWK-JETA-LW (Model A) and GWK-JETJ-LW (Model J). While the wheel assemblies are identical 70D polyurethane with sealed bearings, verify your frame serial range before ordering to confirm compatibility. The kit supersedes obsolete part numbers PT2748L-080 and PT2748J-080.
Q: Can I install GWK-JET A/L-LW on a Model A or Model J frame if I have the frame dimensions?
A: No. While the wheel assemblies are mechanically similar across Model L, A, and J, the axle bore spacing and fastener hole patterns differ between frames. Use GWK-JETA-LW for Model A and GWK-JETJ-LW for Model J. Forcing this kit onto a mismatched frame will cause binding, play, or fastener failure.
Q: What is the wheel hardness rating, and will these wheels mark polished floors?
A: The wheels are 70D Shore A polyurethane to ASTM D2240 standard, which is semi-hard and oil-resistant. These are non-marking formulations suitable for polished concrete and sealed floors. However, heavy loads combined with sharp turns on delicate surfaces can leave minor scuffs. Test in a low-traffic area first.
Q: Do the wheel assemblies come pre-lubricated, and what is the maintenance interval?
A: Yes, sealed ball bearings are pre-lubricated and require no user maintenance. Typical service life under normal duty is 3 to 5 years. If wheels become noisy or spin unevenly after 2 to 3 years, the bearing seals may be compromised. Replacement is not field-serviceable; replace the entire load wheel assembly.
Q: What tools and steps are required to install this kit on a Jet Model L frame?
A: You will need a 1/2-inch wrench or socket set, torque wrench (recommended), and jack stands. Remove the frame from service. Support the carriage on jack stands. Unbolt the old load wheels using the wrench. Install new assemblies by sliding axles through the frame bore, thread fasteners, and tighten to specification (typically 40 to 50 foot-pounds for Grade 5 steel fasteners). Do not exceed torque; overtightening crushes bearing seals.
Q: What is the maximum wheel load capacity, and how does it compare to original equipment specifications?
A: The kit is rated for the full frame capacity of Jet Model L pallet trucks (typically 5,500 pounds total load per wheel pair on a 5,000-pound truck). The 70D polyurethane and sealed bearing design matches OEM specifications. Do not exceed the frame capacity plate rating or bearing fatigue life will decrease.
