ABSTRACT:
A plunger stop for temporarily holding the plunger of a ratchet type chain tensioner in place during installation of the tensioner, or during mounting or removal of the chain, comprises a bifurcated part inserted into a groove in which a pivoted ratchet pawl is situated. The bifurcated part is sandwiched between the pivoted ratchet pawl and a part of the tensioner housing, with the bifurcated part straddling a ratchet pawl-biasing spring in the groove. A grip, which is integral with the bifurcated part protrudes outside the tensioner housing so that it can be grasped manually for removal.
