Frequently Asked Questions
Q: What jack models accept GW 229?
A: GW 229 is engineered for narrow-frame pallet jacks (25-inch width) with load ratings up to 5500 lbs. It is not compatible with standard 27-inch frames. Measure your jack frame centerline to centerline of wheel mounts before ordering. If you install GW 229 on a 27-inch frame, the wheels will not track straight and the jack will pull to one side during operation.
Q: How do I check if my jack needs a 25-inch or 27-inch axle?
A: Measure the inner distance between the two frame ears where the axle bolts attach (frame width). GW 229 fits 25-inch frames; GW 227 or GW 228 fit 27-inch frames. Cross-installing the wrong width causes uneven load distribution, accelerates wheel bearing wear, and can result in axle failure under load. Always verify frame width before purchase.
Q: What is the torque specification for GW 229 installation?
A: Torque GW 229 axle bolts to 40-48 ft-lbs. Use a calibrated torque wrench to avoid over-tightening, which can strip the frame threads. Under-tightening creates axle wobble and leads to bolt loosening during operation. Check bolt tightness after the first 100 operating hours, then every 500 hours or quarterly.
Q: Can GW 229 handle overload conditions?
A: No. GW 229 is rated 5500 lbs static load maximum. Exceeding this rating concentrates stress on the axle shaft and bearings, causing permanent deformation and failure within hours of overload. There is no safety margin—reach or exceed 6000 lbs and the axle will bend or seize. If your loads regularly exceed 5500 lbs, upgrade the entire jack to a 6000-lbs model with GW 231 axles.
Q: How often does GW 229 require greasing?
A: GW 229 uses open-bearing cartridges that require greasing every 250 operating hours or quarterly, whichever comes first. Apply ISO VG 32 lithium multi-purpose grease to the bearing points on each side until grease appears at the wheel. Over-greasing clogs the bearing and increases friction—use only 2-3 grease gun pumps per side per service.
Q: What symptoms indicate GW 229 bearing failure?
A: Squealing or grinding noise during load lift, resistance when spinning the wheel by hand, or one wheel dragging behind the other are signs of bearing wear. If the axle shaft is bent, the wheels will not spin freely or will wobble excessively. Stop operation immediately—continuing with a failing axle increases risk of load drop. Inspect and replace within 24 hours.
