Frequently Asked Questions
Q: Is GWK-HJ55-CK compatible with Total Source HJ5500 pallet jacks?
A: Yes. GWK-HJ55-CK is cross-compatible with Total Source HJ5500 models and is interchangeable with GWK-HJ5500-CK. Both kits provide identical wheel assemblies, bearings, and fastening specifications. Verify your jack serial range to confirm you have an HJ55 or HJ5500 frame before ordering.
Q: What wheel sizes and materials are included in the GWK-HJ55-CK kit?
A: The kit includes two 3 inch by 3.75 inch ultra-polyurethane load wheels (70 Shore D hardness) and two 7 inch by 2 inch polyurethane steer wheels, also rated 70 Shore D. Ultra-poly construction resists flat spotting and edge wear under heavy repetitive loading on warehouse floors.
Q: Does GWK-HJ55-CK come fully assembled or do I need to install bearings and axles?
A: GWK-HJ55-CK ships with factory-installed precision bearings, axle shafts, load wheel axles, lock rings, spiral pins, hub caps, and all fastening hardware. You receive complete wheel assemblies that bolt onto your jack frame. No bearing or axle installation is required.
Q: What maintenance symptoms indicate I need to replace wheels with GWK-HJ55-CK?
A: Replace wheels when you observe flat spotting, chunking, cracks, or hardened zones on load or steer wheels; excessive wobble during rolling; audible grinding or squealing from bearing races; or when wheels no longer roll freely after lubrication. These symptoms indicate bearing fatigue, wheel degradation, or axle damage.
Q: What tools and steps are required to install GWK-HJ55-CK on my HJ55 jack?
A: You need a socket wrench set, snap ring pliers, and a jack stand. Remove the jack from service and secure it on blocks. Remove fasteners connecting old wheel assemblies to the frame. Align new assemblies with frame mounting points and install hardware. Torque bolts per Total Source service manual (typically 18 to 22 foot-pounds for load wheel mounts). Test roll freely before returning to service.
Q: What is the rated load capacity and operating temperature range for GWK-HJ55-CK wheels?
A: Load capacity matches your HJ55 pallet jack frame rating, typically 5500 pounds. Ultra-polyurethane wheels operate safely from minus 10 degrees Fahrenheit to plus 130 degrees Fahrenheit. Do not use in freezing conditions without verifying wheel flexibility; ultra-poly hardens below minus 10 degrees and risks cracking under load.
