Abstract: A clutch release assembly for use in a motor vehicle includes a retainer sleeve, a retainer, a release bearing and an input shaft sleeve. The retainer has an axis of rotation, and has both a first end and a second end. The retainer is disposed on the first end of the retainer sleeve. The retainer is adapted to engage a radially inwardly directed end of one of a lever and a diaphragm spring finger. The release bearing is disposed on the second end of the retainer sleeve. The input shaft sleeve is disposed radially within the retainer sleeve and has a first end and a second end. The input shaft sleeve is radially sized to slidably fit both within the retainer sleeve and over an input shaft. The input shaft sleeve has a radially inwardly extending anti-rotation feature, and a radially outwardly extending travel limit. The input shaft sleeve has a smooth low friction surface disposed toward the retainer sleeve. The input shaft sleeve protects the retainer sleeve from the input shaft.

Abstract: The position of an adjusting ring used in a clutch adjustable for wear is monitored by an indicator comprised of a pin having a first end biased into engagement with the adjusting ring and a second end which is visible from outside of the clutch housing. As the adjusting ring is turned to compensate for clutch wear, the adjusting ring moves axially with respect to the clutch housing and the pin moves progressively into the clutch housing. When the end of the pin is no longer projecting from the housing, the mechanic knows that clutch wear can no longer be compensated for by axially advancing the adjusting ring. In accordance with a preferred embodiment, the indicator pin is made of nylon and is retained in a nylon sleeve while being biased by a coil spring. The assembly is initially held together by abutment between a rib projecting from the pin and an end surface of the sleeve.
