Bolt Torque Chart
TIGHTENING WHEEL NUTS
Standard 20mm wheel studs and nuts should be tightened to torque 644 Nm (475 Ft.-Lbs.) during initial operation of the grain
cart and then checked for proper torque after every 10 hours of use. Failure to do so may damage wheel nut seats. Once seats are
damaged, it will become impossible to keep nuts tight.

SAE Fasteners
Always tighten hardware to these values unless a different torque or tightening procedure is listed for specific application.
Fasteners must always be replaced with the same grade as specified in the manual parts list. Always use the proper tool for
tightening hardware. Make sure fastener threads are clean and you start thread engagement properly. Torque values in the
charts below use a torque coefficient of 0.17.
