Jacking and Towing
Jack Points
[WARNING]
Proper jacking procedures and basic safety
measures must be observed to ensure the safety of personnel
while working under the bus. Always check the serviceability of
any lifting equipment prior to use. Ensure that the lifting device
is of sufficient strength to handle the bus, and that the surface
provides the necessary firmness to support the weight of the bus
concentrated on the footprint of the jack. Never move under a
bus supported only by a hydraulic jack.
1. Park the bus on a flat, level surface of sufficient firmness to sup-
port the jack.
2. Chock the wheels in both directions.
3. Use only jacks and jack stands of sufficient capacity to support
the bus. Following the jack manufacturer’s recommendations,
place the jack securely under the axle at the spring or suspen-
sion beam, nearest the tire/wheel to be repaired.
4. Jack the bus only to the height necessary to service.
5. Support the bus with blocks or jack stands under the frame
rails.
Towing
If the bus is towed with the rear wheels on the road, the driveshaft must be prevent-
ed from turning in order to avoid possible damage to the automatic transmission.
This is accomplished by removing the rear axle shafts, and covering their openings
with caps to prevent rear axle lubricant spillage.
Also, on
Vision
buses equipped with air brakes, if full normal air pressure cannot
be provided the air system, the spring brakes must be mechanically caged to prevent
their engagement.
1. Apply the parking brake and chock the wheels while preparing the vehicle
for towing.
2. Remove the stud nuts and washers from the center hub.
