This chain tensioning system consists of an
upper and lower chain tensioner arm which is
supported by a pivot pin secured between the
outer and inner frame channel. A tensioner
spring is connected between the upper and
lower assembly keeping a constant tension on
any slack there may be in the chain.

(6mm) or greater, replace the nylon
