CA 2299882
An adjustable ramp helix is disclosed for attachment to the clutch of a snowmobile or other vehicle. The adjustable ramp helix may include a base having a throat. Extending upwardly from the base opposite to the throat may be three equally sized ramp supports where each ramp support has an adjustable ramp. Each adjustable ramp is preferably pivotally attached to the top portion of a corresponding ramp support for positioning to the interior thereof. Each of the adjustable ramps includes an arcuate foot section which passes through an arcuate aperture in the base. A threaded outer dial collar may be rotatably engaged to the throat for positioning with respect to the collar. The collar engages the arcuate foot sections of the adjustable ramps to uniformly and simultaneously elevate the adjustable ramps above the ramp supports. The elevation of the adjustable ramps provides a new angle for the bushing faces for engagement to the clutch of a vehicle to establish an alternative speed of shifting for a snowmobile or other engine. An operator may thereby adjust the speed of shifting for a snowmobile or other vehicle without disassembly of the clutch and replacement of the helix during use in high altitude, varying snow, or changing temperature conditions.
