18. A chain guide comprising:
-
a bracket adapted for being secured to an associated engine, said bracket comprising a support, a bracket leading end and a bracket trailing end spaced from said leading end in a chain movement direction, said bracket further comprising a first saw-tooth fixing element defined by a plurality of teeth that extend in said chain movement direction and that are raked in said chain movement direction;
a plastic guide shoe comprising a shoe leading end, a shoe trailing end, a chain guide surface adapted for slidably supporting an associated chain moving in said chain movement direction, and an inner surface positioned adjacent said support of said bracket, said guide shoe selectively movable slidably relative to said support of said bracket between a first position where said guide shoe is separable from said bracket and a second position where said guide shoe is fixedly secured to said bracket, said guide shoe comprising;
(i) a portion defined at said shoe leading end that that engages a portion of said bracket when said shoe is located in said second position; and
, (ii) a second saw-tooth fixing element that mates with said first saw-tooth fixing element when said guide shoe is located in said second position, said second saw-tooth fixing element defined by a plurality of teeth that extend in said chain movement direction and that are raked in a direction opposite said chain movement direction. - View Dependent Claims (19, 20)
