Wheel Nut Check
P4 MM 40; 5th Generation Cascadia MM
Important: After a wheel has been installed,
the wheel nut torque must be rechecked after 50 to 100 miles (80 to
160 km) of operation.
Check the torque on all wheel nuts. See Table for torque specifications, and see Fig. for the wheel nut tightening sequence.
Note: Torque values
are given for lubricated threads. Apply 2 drops of SAE 30W oil to
a point between the nuts and flanges.
Notice: Insufficient
wheel nut torque can cause wheel shimmy, resulting in wheel damage,
stud breakage, and extreme tire tread wear. Excessive wheel nut torque
can break studs, damage threads, and crack discs in the stud hole
area. Use the recommended torque values, and follow the tightening
sequence shown in Fig. .
