If machines were assembled in cold conditions at −10 °C (14 °F) or below, inspect the mounts in four places under the cab for proper installation torque. If the mounts are not seated properly or the torque is low, replace the hardware and mounts and torque to proper specification. The mounts should be kept at −10 °C (14 °F) or above for at least 24 hours before installation.

Note: All future 773F, 775F, and 777F Off Highway Trucks assembled in temperatures below −10 °C (14 °F) should follow the above practice.
