Abstract: An air intake manifold for providing air from an exterior of a vehicle to a ventilation system of the vehicle. A primary plenum chamber has an intake passageway formed therein. The intake passageway is adapted to allow air from the exterior of the vehicle to enter the primary plenum chamber. A secondary plenum chamber is located within the primary plenum chamber. A shield is attached to the primary plenum chamber and extends over the secondary plenum chamber. A secondary inlet passageway is formed in an upper portion of the secondary plenum chamber. The secondary inlet passageway fluidly connects the primary plenum chamber to the secondary plenum chamber. A filter member covers the secondary inlet passageway to prevent debris from entering the secondary plenum chamber via the secondary inlet passageway. An outlet passageway is formed in the secondary plenum chamber. The outlet passageway fluidly connects the secondary plenum chamber to the ventilation system.

Abstract: A clutch actuation system (20) of a vehicle for actuating a clutch lever (22) of a clutch system (24) in response to the actuation of a clutch pedal (26) in a vehicle cab (28). The clutch pedal (26) is attached to a clutch pedal shaft (38). A first bearing member (40) pivotably supports one end of the shaft (38), and a second bearing member (60) pivotably supports the other end. The first bearing member (40) is attached to the inside of the vehicle cab (28). The shaft (38) extends through the second bearing member (60) at a vehicle firewall (50) and through the firewall into the engine compartment when the clutch actuation system (20) is operably installed on the vehicle. A clutch pedal lever (64) is attached to a shaft end within the engine compartment. A clutch return spring (86) biases the clutch pedal (26) via the clutch pedal lever (22) and the shaft (38).

Abstract: A component support system for a vehicle provides a way to firmly attach a component to a vehicle. The component support system includes a component member adapted to attach to the component to be mounted and a support member adapted to attach to the vehicle. The component member has a first mating surface with a first channel formed thereon. The support member has a second mating surface with a second channel formed thereon. The second channel is adapted to interfit with the first channel. Because the channel configurations are non-symmetric about an axis allowing the parts to interfit in only one orientation, the component support system is self-aligning. A fastener is adapted to retain the component member against the support member when the first channel is interfitted with the second channel.
