Towing
Warning: Do not tow an unbraked vehicle if the combined weight of both vehicles is more than the sum of the gross axle weight ratings (GAWR) of the towing vehicle. Otherwise brake capacity will be inadequate, which could result in personal injury or death.
Important: When it is necessary to tow the vehicle, make sure the instructions below are closely followed to prevent damage to the vehicle.
Notice: When towing or pushing the vehicle, regardless of the distance or speed traveled, either disconnect the driveshaft at the rear axle and support it as necessary, or remove the axle shafts. Failure to do this when towing the vehicle with the rear wheels on the ground could result in damage to the transmission and other parts.
Note: Towing rules and regulations vary from federal, state, local, and transit authority. These laws must be followed when towing the bus.
Front Towing Hookup
- Disconnect the battery ground cables.
- Remove both drive axle shafts.
- Cover the ends of the hubs with metal plates or plywood cut to fit the axle opening, and drilled to fit the axle shaft studs. This prevents lubricant from leaking out and will keep contaminants from getting into and damaging the wheel bearings and axle lubricant.
- Remove the bumper.
- Attach the towing device. Due to the many variables that exist in towing, positioning the lifting and towing device is the sole responsibility of the towing-vehicle operator.
- Lift the vehicle and secure the safety chains. If extra towing clearance is needed, remove the front wheels.
- Connect the clearance lights, taillights, and signal lights. Connect any special towing lights required by local regulations.
- Chock the tires on the disabled vehicle and connect the towing vehicle's air brake system to the vehicle being towed. Then, release the spring parking brake and remove the chocks.
Notice: The vehicle shouldnever be towed from the rear. The gross axle weight rating (GAWR) of the front axle may not be sufficient to support the increased load when towing from the rear. This could damage the front axle.
Notice: Failure to protect the frame rails from the chains could cause damage, leading to eventual frame failure.
Warning: Failure to chock the tires or connect the tow truck's air brake system before releasing the spring parking brakes could allow the disabled vehicle to suddenly roll. This could cause property damage or personal injury.
