for engines with a rear oil drain plug thats center is about 3/8" from the bottom of the engine
.
retract the push bolt until its end is even with the body of the adjuster then line it up with the drain plug mark where your 1/4" mount holes will need to be then drill the 2 mount holes and bolt it down
.
now to adjust the engine and chain just loosen the engine mount bolts then turn the push bolt until the engine is where you want it to be then tighten the jam nut to the body of the adjuster and retighten the engine mount bolts
.
now no amount of chain pull or engine vibration will allow the engine to slide backwards
.
this adjuster requires a minimum of 3/4" of mount space behind drain plug . the push bolt is 2 1/4" long make sure you have clearance for it to. a shorter bolt can be used if needed
.
$15 shipped in the USA
