Patent ID: 8348356

Claim:
An idler recoil and tension adjustment assembly comprising: a housing including a housing contact end and a yoke contact end; the housing accommodating a reciprocating shaft including a idler recoil section and a tension adjustment section; the tension adjustment section being in communication with a grease port; the idler recoil section being in communication with a gas port; the grease and gas ports being coupled to the reciprocating shaft; the reciprocating shaft being slideably coupled to a blocking plate and the housing being coupled to an abutment that engages the blocking plate in the event the idler recoil section develops a leak thereby causing the shaft to move towards the housing contact end and the blocking plate towards the grease port; wherein engagement between the abutment and blocking plate pushes the blocking plate to a position where the grease port is blocked by the blocking plate when the idler recoil section develops a leak.
