Abstract
A bearing arrangement to reduce the effects of thermal expansion in a marine transmission includes a pinion gear thrust bearing, a clutch shaft thrust bearing, a shaft roller bearing and a thrust washer. The clutch shaft thrust bearing is retained on one end of a clutch shaft and the shaft roller bearing is retained on the other end of the clutch shaft. A pinion gear is rotatably retained on the clutch shaft. The pinion gear thrust bearing is retained on the pinion gear with a bearing retainer. The thrust washer is retained on the bearing retainer. An end of the clutch shaft thrust bearing rotates relative to the thrust washer and makes contact therewith. The length of thermal expansion in the transmission housing is limited to the distance between the opposing ends of the two thrust bearings.
