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: SAE for SAE hardware and Metric for Metric hardware.
Make sure fastener threads are clean and you start thread engagement properly.
All torque values are given to specifications used on hardware defined by SAE J1701 & J1701M (JUL 96)

Standard 3/4" wheel studs and nuts should be tightened to torque 500 Ft.-Lbs and standard 22mm studs should be tightened
to torque 700 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.
