Wear indicator for adjustable clutch

In combination with a clutch having a clutch housing with internal threads in which is threadably mounted an adjusting ring which adjusting ring advances axially to accommodate for wear in the clutch and which adjusting ring has a rear surface facing an inner surface of the clutch housing, an adjusting ring position indicator comprising:

• a sleeve inserted through the clutch housing in alignment with the rear surface of the adjusting ring, the sleeve having a bore therethrough and including means thereon for retaining the sleeve in the clutch housing;
• a pin slidably received within the sleeve, the pin having a first end for abutment with the rear surface of the adjusting ring and a second exposed end visible from outside of the clutch housing, whereby when the first end of the pin is in engagement with the rear surface of the adjusting ring, the exposed end of the pin provides a visual indication of the position of the adjusting ring with respect to the clutch housing and thus of wear undergone by the clutch means for releasably holding the pin retracted comprising an abutment proximate the second end of the pin which engages a surface on the sleeve when oriented in one direction and clears any surface on the sleeve when oriented in another direction.
