PROPELLER SHAFTS
DESCRIPTION
Power is transmitted from transmission to
rear axle through one or more propeller shaft and
universal joint assemblies. The number of pro­
peller shafts and universal joint assemblies vary
with vehicle wheelbases and combinations of trans­
mission and rear axle equipment. Some typical
arrangements are shown in figure 1.
All propeller shafts are tubular type. Asplined
slip joint is provided in each drive line. If a single
propeller shaft is used, slip joint is at transmis­
sion end of shaft; if two or more shafts are used,
slip joint is at forward end of rear shaft. End of
slip yoke is sealed by afeltorcork washer, held in
place by asteel washer and a dust cap which threads
onto end of yoke. Fixed yoke may be either welded
to propeller shaft tube as shown in figures 3 and
4, or it may be splined to a stub shaft and secured
with a nut and cotter pin as shown in View A, figure
5. Alignment arrows on slip yoke and shaft pro­
vide for alignment of yokes at assembly.
