Abstract: A compact creeper gear arrangement (70) for a multiple speed transmission (12) in which the creeper gear input (78) and output shafts (88) are laterally spaced from and parallel to the major shafts within the transmission. The creeper gear arrangement (70) utilizes an input gear (74) integral with one of the speed range gears (72) and selectively coupled to a shaft (24) that provides an input to a mechanical front wheel drive assembly (41). The creeper gear arrangement (70) is a dual speed selectively engageable transmission where much of the mechanism is located within otherwise unused space within the transmission.

Abstract: A fan shroud having an integrated aspirator is provided comprising a first section and a second section. The first section and second section are designed to mateably engage one another so as to form an air passage between a fan and a cooling module of a vehicle. The first section of the shroud includes an air duct formed by a channel in the shroud and a similar channel in a duct cover, so that when the duct cover is mated to the first section of the shroud an air duct is created. A first end of the air duct terminates at an aperture disposed in an end of shroud situated proximal to the fan. A second end of the air duct curves upwardly to a nozzle provided on the top side of the duct cover. A pre-cleaner unit having an air intake and an air exhaust is aspirated through an aspirator port. When the pre-cleaner is mounted to the shroud, the aspirator port is disposed in the nozzle of the duct cover. The aspirator port is thus in communication with the air duct and the shroud aperture.

Abstract: A fan shroud is provided having upper and lower sections. The sections are designed to mateably engage one another at mating flanges so as to form an air passage between a fan and a cooling module of the vehicle. The upper section of shroud includes an aspirator portal in an upper surface thereof. An aspirator is provided having an air intake and an air outlet. The aspirator is supported in the lower section of the shroud proximal to the fan with the air outlet facing the fan. An engine intake air pre-cleaner unit having an air intake, an aspirator port, and an air exhaust is mounted to the shroud by aligning mounting tabs on the pre-cleaner with mounting bosses on the shroud so that the aspirator port is disposed in proximity to the aspirator portal in the upper section of shroud. One end of an aspirator hose is connected to the aspirator port of the pre-cleaner and passes through the aspirator portal. The other end of the aspirator hose is connected to the air intake of the aspirator.
