Shockwave InstallREPLACING THE helix on a reverse cam secondary Ski-Doo QRS clutch is not a quick task. To do the job, you need a helix compressor like those made by Tyler Olson and the crew at Olson Power Equipment, my local Ski-Doo dealer in North Branch, Minn.
First, you must remove the entire jackshaft/driven clutch assembly and place the clutch in a vice to make the swap. To install the helix in the QRS clutch, first, remove the clutch guard and then use the belt deflection tool to loosen the driven, so you can remove the belt. Next, remove the upper chaincase fill cap and breather. Thread in the upper gear-retaining tool and tap the puller to drive the jackshaft out of the top gear in the chaincase.
Once the jackshaft has separated from the gear, carefully pull the jackshaft/driven assembly through the subframe bracket. Place the driven in a vice and then thread the cam compressor onto the driven clutch. First an internal sleeve is threaded in and an external sleeve slides over the puller. Then the spring compressor screw is inserted into the QRS secondary and tightened until the helix is fully compressed. Next, the cam retention screws must be removed from the back of the driven clutch. If necessary, heat can be applied to get the screws to break loose. The helix, spring, and stopper washer should then slide off of the secondary clutch.
The procedure is essentially reversed for installation of the Shockwave helix. The helix, spring, and washer slide onto the shaft. The driven spring compressor can then be threaded into the shaft and the spring compressor screw used to compress the assembly. Once fully compressed, align the Shockwave's four posts with the mounting holes and torque the four bolts to 24 ft.-lbs. Simply slip the jackshaft through the subframe, tap the gear onto the jackshaft, and thread the upper chaincase bolt into the jackshaft.
Finally, torque the gear bolt down and replace the chaincase filler cap. Moving to the clutch side, you need to slip the belt over the clutches, tighten the driven clutch swivel ring onto the cam with the suspension adjustment tool and put on the belt guard. Now you're ready to ride.
