69 attached to plate 54 proximate the engine jackshaft 66 rotates at a higher speed and lower torque than the engine shaft 51 jackshaft 66 reaches the second stage 67 fig3 of the cvt module through a bearing 70 affixed to a support plate 72 mounted atop a vertically extending intermediate plate 74 that is secured to horizontal plate 44 jackshaft 66 terminates within and is splined to a variable drive cvt pulley assembly 84 in cvt module second stage 67 pulley 84 can change its effective diameter varying the speed and torque transmitted to lower pulley 88 by a second or cvt belt 89 cvt pulley 84 will be driven by jackshaft 66 at a higher speed than the engine shaft 51 therefore operating at a lower torque a suitable cvt unit is available from cv tech company drummondville quebec canada the cvt unit comprises a first and preferably upper pulley 85 with cooperating conical halves 87 a and 87 b that are axially spaced apart a distance that establishes the belt gear ratio a second jackshaft 92 positioned below jackshaft 66 is splined through lower cvt pulley 88 the cvt belt 89 extends to lower cvt pulley 88 from the upper.
