Product Description
GWK-PTH-CK is an OEM-specification complete wheel kit for Crown manual pallet jacks, compatible with PTH and PTH50 models (later serial ranges). It combines ultra-polyurethane (70D) load rollers and nylon steer wheels with 20mm bearings, supplied with steel axles and precision fasteners for enhanced durability, wear resistance, and floor protection. Mechanical assemblies exceed OEM tolerances for fit and function.
Compatibility: Fits pallet jacks made by Crown, model PTH. SKU: GWK-PTH-CK

Frequently Asked Questions
Q: Will GWK-PTH-CK fit my Crown PTH pallet jack?
A: GWK-PTH-CK fits Crown PTH and PTH50 models with serial number 3-183850 and higher. If your PTH50 is older (serial below 3-183850), verify the wheel mounting holes and axle diameter before ordering. Check your nameplate on the frame for the serial number to confirm compatibility. Later production PTH models have standardized 20mm bearing bores and compatible fastener patterns.
Q: What is the load rating for GWK-PTH-CK wheels?
A: The GWK-PTH-CK wheel kit is rated for the OEM specification of your Crown PTH or PTH50 pallet jack, typically 5000 lb capacity at a 24 inch load center for PTH models. The 70D Shore durometer ultra-polyurethane wheels are engineered to handle this rated load without deformation. Do not exceed the jack nameplate capacity, and inspect wheels quarterly for flat-spotting or cracking.
Q: Can I replace just the load wheels without replacing the steer wheels?
A: Yes, but not recommended. The GWK-PTH-CK includes both load roller assemblies and steer wheel assemblies. If only load wheels are worn (metal-on-floor contact or severe flat-spotting), you can source a load-wheel-only kit. However, if steer wheels are also degraded, replacing both together ensures uniform performance and handling characteristics. Mixed old and new wheels create handling inconsistency.
Q: What tools do I need to install GWK-PTH-CK?
A: You will need a socket wrench set (10mm to 17mm typical), snap ring pliers for the snap ring removal, a bearing puller if the old wheels must be pressed off, and a light press or bearing driver tool if bearings need to be moved to new axles. All fasteners and snap rings are included in the kit. Most installations take 45 minutes per wheel assembly. Do not use impact tools on bearing bores.
Q: How long do GWK-PTH-CK wheels last in normal warehouse use?
A: Under normal warehouse conditions (smooth concrete, 3000 to 4000 hours annual use), GWK-PTH-CK wheels typically last 18 to 24 months before noticeable wear reduces maneuverability or floor protection. Life decreases on rough concrete, outdoor use, or prolonged loads at the jack capacity. Inspect wheels monthly for cracks, and replace when load rollers lose 25 percent or more of their original diameter or when flat-spotting becomes visible.
Q: Does GWK-PTH-CK include sealed or open bearings?
A: GWK-PTH-CK includes 20mm sealed roller bearings that reduce maintenance and extend wheel life by preventing water and dust infiltration. The precision-sealed design is oil-impregnated and does not require greasing. Do not attempt to open or repack these bearings. If a bearing binds or spins rough, replace the entire wheel assembly rather than servicing the bearing.
