of track width, tire pressure, and load capacity. Size changes such as rim width, center piece location, larger or smaller diameter, etc., without written factory recommendations, may result in an unsafe condition regarding stability. Wheel installation It is extremely important to apply and maintain proper wheel mounting torque. Wheel nuts must be installed and maintained at the proper torque to prevent loose wheels, broken studs, and possible dangerous separation of wheel from the axle.
Page 61
The tightening of the nuts should be done in stages. Following the recommended sequence, tighten nuts per wheel torque; Table 5-3 Wheel Torque Table Torque Sequence 1st Stage 2nd Stage 3rd Stage 75 Nm/54.3 ft·lb 150Nm/108.5 ft·lb 275 Nm/198.9 ft·lb Wheel nuts should be torqued after first 50 hours of operation and after each wheel removal.
