Frequently Asked Questions
Q: Will GWK-PTH50-CK-SS fit my Crown PTH50 pallet jack?
A: GWK-PTH50-CK-SS is engineered for Crown PTH50 models with serial number 7-000000 and higher. Before ordering, verify your serial number on the jack frame. This complete kit includes both load wheels and steer wheels, so it fits the entire wheel assembly. If your jack is an older PTH50 model below serial 7-000000, contact your supplier for the legacy wheel kit option.
Q: What is the load capacity and wheel material for GWK-PTH50-CK-SS?
A: GWK-PTH50-CK-SS supports rated loads up to 5000 lbs at a 24 inch load center. The kit features two Ultra-Poly 70D load wheels for superior rolling performance and floor grip, paired with polyurethane steer wheels. Stainless steel ball bearings eliminate corrosion issues in wet or food-service environments. The assembly is OEM-level and requires no modification to your pallet jack frame.
Q: What tools and steps are required to install GWK-PTH50-CK-SS?
A: Installation is straightforward. You will need a 9/16 inch wrench and a 3/8 inch socket. (1) Lower the jack fully and unload any cargo. (2) Remove the cotter pins and axle nuts from the existing wheels using your wrench. (3) Slide the old wheels off the axles. (4) Install the new load wheels first, ensuring the 70D wheel faces forward. (5) Install the steer wheels on the rear axles. (6) Reinstall axle hardware and secure with new cotter pins. The kit includes all required hardware. Do not operate the jack until all wheels are fully secured.
Q: Does GWK-PTH50-CK-SS have any cross-reference or equivalent part numbers?
A: GWK-PTH50-CK-SS is the stainless steel variant of GWK-PTH50-CK. The standard OEM part number reference is GWK-PTH50-CK with cross-reference GPSN080. However, GWK-PTH50-CK-SS (the stainless bearing version) does not have published cross-references from other manufacturers. If you need equivalent parts, verify directly with Crown or your distributor as aftermarket stainless variants may have different SKUs.
Q: What is the expected lifespan of GWK-PTH50-CK-SS wheels?
A: Under normal warehouse conditions (indoor, smooth concrete floors), Ultra-Poly 70D load wheels last 18 to 36 months. Stainless steel ball bearings extend overall kit lifespan by resisting corrosion and seizing. In wet or corrosive environments (food plants, freezers, salt water proximity), stainless bearings can add 50 percent more service life compared to standard steel. Inspect wheels quarterly for flat spots or cracks. If a wheel is damaged, replace the entire wheel assembly; do not attempt repair.
Q: What maintenance is required for GWK-PTH50-CK-SS?
A: GWK-PTH50-CK-SS requires minimal maintenance. Bearings are sealed and factory-lubricated for life. Wipe wheels clean monthly to remove dirt and debris that can cause uneven rolling. Check axle hardware (nuts and cotter pins) every six months. If a wheel begins to bind or make noise, the bearing is likely contaminated; replace the entire wheel assembly. Do not attempt to repack or clean sealed stainless bearings. Rotate jacks between different areas of your facility to distribute wear evenly.
