Abstract
A sealing arrangement is provided between a clutch cover and adjusting ring wherein the clutch cover and adjusting ring are threadably engaged by an internal thread on the clutch cover and an external thread on the adjusting ring. The clutch cover has a smooth, cylindrical surface proximate the internal thread while the adjusting ring has a groove proximate the external thread with an 'O' ring in the groove which is in sealing engagement with the smooth, cylindrical surface. The 'O' ring retains a layer of grease between the threads substantially eliminating purging of the grease.
