As the last Windsor was produced, 26 April, 1945, mounting track was still a three man operation(
1945, not three person).
The accepted practice of positioning the track at 62-3/8" on centre, then rolling the carrier onto track until one foot extends behind center of the rear bogie is shown. Using a cable and track pin, two men to pull the track over the idler wheels and sprocket.
The Ford Service Bulletin describes the next step of the procedure:
"Operate carrier carefully in reverse gear with the brake locked on side opposite to track being installed." Or: "Start engine and operate slowly with transmission in reverse gear. This will tighten track and permit easy application of track jack." Clearly one needs to be on the correct page of the procedure.
