Towing
If the bus is towed with the rear wheels on the road, the driveshaft must be
removed in order to prevent the drive motor input shaft from turning which
could damage the motor. This is accomplished by removing the rearmost
driveshaft. Also, on buses equipped with air brakes, if full normal air pressure
cannot be provided to the air system, the park brakes must be mechanically
caged to prevent their engagement. See
Caging the Spring Brakes.
1. Apply the parking brake and chock the wheels while preparing the ve-
hicle for towing.

WARNING!
On units with hydraulic brakes the parking brake
becomes ineffective when the driveshaft is removed which could
allow the bus to roll if the wheels are not chocked. CHOCK THE
WHEELS to avoid personal injury or death.
2. From under the bus locate the driveshaft behind the axle housing for re-
moval. Remove the capscrews that secure the yoke straps at the forward
universal joint.
