SECTION 09: PROPELLER SHAFT
DOB 1300-1556 | X3-45 Commuter PA-1648 Maintenance Manual First release Oct 2020
2. PROPELLER SHAFT DESCRIPTION
The propeller shaft transmits power from the
transmission to the differential. The propeller shaft
is Dana Spicer Life Series SPL250 type with tubular
shafts. It is provided with two heavy-duty universal
joints (
FIGURE 1).
The propeller shaft has a half round end yoke at
each end. The slip yoke is connected to the
differential by a half round end yoke with two needle
bearings.
The other extremity (tube yoke assembly) is
connected to the transmission by a half round end
yoke with two needle bearings (Allison
transmission).
Furthermore, a slip joint on the propeller shaft
compensates for variations in distance between the
transmission and the differential, or between the
output retarder (optional on the automatic
transmission) and differential.
The rise and fall of the drive axle bring about
these variations as the vehicle passes over
uneven surfaces. The slip joint also eases
removal of the transmission or the drive axle.
