CPC Quick Shift / Quick Adjust Cam ArmsInstructions
Thank you for purchasing the highest quality an the highest technological advanced cam arm in the industry. These cam arms are specifically designed to fit 2004 and newer Arctic Cat drive clutches using the set screw design where the cam arm is locked into the pivot bolt with a set screw. You can now adjust the weight of these cam arms by simply adding or subtracting set screws. The accessibility of this adjustment can be made without the removal of the cam arms or by removing your drive belt. Each set of CPC Quick Shift/Quick Adjust cam arms can be loaded up with set screws to increase the weight up to 10 grams. Please follow the instructions below to get the most performance out of this product.
Set screws come in the following sizes and weights.
1/4 x 1/4 = .75 grams, 1/4 x 3/8 = 1.34 grams, 1/4 x 1/2 = 1.98 grams, 1/4 x 5/8 = 2.50 grams, 1/4 x 3/4 = 3.10 grams, 1/4 x 1 inch = 4.15 grams.
#1.When first installing cam arm to pivot bolt, apply a drop of Loctite 620 green retaining compound (not included) inside of cam arm and into the small 8-32 set screw, then tighten securely. If you need to remove the cam arm, apply a little heat with a torch to soften Loctite.
#2. Installing more set screws will decrease RPM's.
#3. Removing set screws will increase RPM's.
#4 Engagement RPM's is best achieved by installing a different tension drive spring.
#5 Installing set screws at the tip of the cam arm (toe loading) will give improved shift out at high vehicle speed (generically speaking over 75 mph) If you decide to toe load your cam arms, you must install the set screw prior to installing the cam arms. You can install up to 1/2 inch long set screw in the tip of the weight before the set screw bottoms out against a stop.
#6. If no set screw is installed at the tip of the cam arm (clip tip), then improved low speed performance will be achieved at the expense of decresed performace at high vehicle speed (just the opposite #4)
#7. Best clutching is achieved by knowing where your power peek is and by adding as much weight as you can without a loss of RPM's at full shift out.
#8 If you have difficulty installing the set screws, you should try cleaning the threads with a gun cleaning brush and solvent, then clean with compressed air. never use a tap, it will break off in the cam arm because the cam arm is heat treated. If you are still having trouble getting the set screws in, run each set screw through a 1/4 X 20 die to remove the burrs on set screw and then apply a drop of blue Loctite to prevent the set screw from coming out.
#9. For additional information, a Clutch Tunning Handbook can be purchased here on the website for $19.95.
Safety
#1. Never run the motor without the clutch gaurd or hood open.
#2. Make sure that each cam arm has the same length and number of set screws in order to keep the cam arms balanced.
#3. Always use set screws with lock-tigh compound on the thread. If the set screws loose this compound then we require a drop of blue Loctite to secure the screw. Screw removal will require the cam arm to be heated to soften the blue Loctite.
#4. Always bottom out each set screw to prevent it from coming out. The lock-tight compound on the threads is used as a precaution for saftey reasons to minimize the possibility of a set screw coming out while the motor/drive clutch is turning.
