Frequently Asked Questions
Q: What is GW 421 steer wheel axle rated for in terms of frame size?
A: GW 421 is engineered for wide-base manual pallet jacks with frame widths of 30 to 36 inches. The axle shaft is 1.0 inch diameter and features heavy-duty double-seal bearings. Do not use GW 421 on standard 24-inch frames; the oversized bearing housings will not fit the frame mounting points.
Q: Does GW 421 steer wheel axle require special bearing grease?
A: GW 421 uses sealed cartridge bearings that are pre-packed with NLGI Grade 2 lithium-complex grease at the factory. Do not attempt to relubricate sealed bearings. If seals fail and bearings are exposed, clean and repack with only NLGI Grade 2 EP lithium grease rated for roller bearing service.
Q: What bolt torque specification applies to GW 421 steer wheel axle mounting?
A: GW 421 frame bolts must be torqued to 25 foot-pounds using 0.5 inch Grade 5 capscrews. Undertorqued bolts allow axle migration and creeping wear. Overtorqued bolts above 28 foot-pounds risk stripping the frame threads. Use a calibrated click-type torque wrench and verify torque every 500 hours.
Q: Can GW 421 steer wheel axle be removed without removing the load platform?
A: You can remove GW 421 without removing the load platform if the jack is lowered fully and the forks are retracted. However, access is extremely tight on wide-base frames. Most technicians remove the platform (6 bolts) to gain clearance for arbor press alignment. Platform removal adds 15 minutes to the job but prevents press angle errors.
Q: What is the service life of GW 421 steer wheel axle under continuous warehouse operation?
A: GW 421 is rated for 8000 to 10000 operating hours in continuous warehouse duty. Actual life varies based on floor conditions, operator technique, and maintenance frequency. Rough floors reduce life by 30 percent. Inspect the axle every 2000 hours and replace immediately if you observe radial play exceeding 0.25 inches.
