Abstract: An oil dam coupling for connecting an output shaft of a transmission arrangement to an input shaft of a pump assembly. The oil dam coupling includes a first member splined to the output shaft and a second member splined to the input shaft. The first member has an end plate which forms a cavity and retains oil within the cavity. The second member engages the first member within the cavity. The oil interacting between the first member and the second member within the cavity will reduce torsional wrap of the output shaft and reduce noise.

Abstract: Countershaft transmissions are useful for vehicles such as lift trucks or the like. But obtaining the desired speed reduction ratios and alignment of the various axes where space is at a premium is difficult. The subject countershaft transmission provides two forward speeds and two reverse speeds using four compactly grouped rotating clutch assemblies of the interleaved multiple plate and disc type for selectively connecting a plurality of constantly meshing gears in preselected patterns. A reverse clutch assembly is mounted on a first shaft, a forward clutch assembly and a low speed clutch assembly are mounted on a second shaft, and a high speed clutch assembly is mounted on a third shaft. A fourth shaft having a bevel pinion gear thereon is located at a minimal drop height "D" from the first shaft so that the longitudinal axis of the bevel pinion gear can intersect the transverse axis of a bevel ring gear associated therewith.

Abstract: A fluid intake screening device (10) is installed in a case (12) defining a sump (14), an opening (20), and an intake passage (28). A tubular baffle member (36) extends from the opening (20) into the sump (14), supports a tubular filter assembly (34) within it, and defines a chamber (52) therebetween. The baffle member (36) has a slot (54) for controllably directing fluid from the sump (14) to the chamber (52). An indexing apparatus (56) positions the slot (54) of the baffle member (36) and adjacent the bottom of the sump (14) and minimizes fluid aeration and turbulence with low fluid levels. A closure apparatus (38) can be removed from the case (12) to permit servicing of the filter assembly (34).
