Vacuum Truck Transfer Case

Vac2Go Operation

The transfer case on a Vac2Go vacuum truck is located next to the blower. The transfer case enables the truck chassis engine to either drive the truck on the road or to transfer the power to the blower to engage the blower and allow the vacuum truck to suck material. When the vacuum truck is in Road Mode, the drive shaft is connected to the rear drive axles and disconnected from the blower. When the vacuum truck is in Blower Mode, the engine driveshaft is diverted to the blower and away from the rear axles.

**Note: The blower can only be operated when the truck is stationary and the parking brake is applied.

There are two sets of gears in the transfer case nose cones. One is for the blower and one is for driving on the road. The transmission of the drive is done be engaging or disengaging these sets of gears.

A drive line guard is in place to cover the upper drive line from the transfer case to the blower. This is to remain in place unless the driveline has to be worked on. A latched, hinge door is provided for easy access to the driveline for greasing, which should be closed and latched when the blower is running.

**Note: The driveshaft is extremely dangerous when rotating and can cause injury or even death. Once the blower is engaged, keep a safe distance from the driveshaft and also keep any tools or objects a safe distance away. Never go underneath the vehicle with the engine running. Never work near a rotating drive shaft. Never attempt to engage or disengage the pump or any driven equipment from underneath the vehicle with the engine running.
