CCW CRANKING OCDT > Right side ( overrunning clutch drive tool ) NOTE: Made Exclusively for current manufactured SkyHawk GT5A-ES & Avenger 85 Engines that can utilize Cordless Drill cranking. Will not work with any other engines. "Over Running Clutch Drive Tool" for hand held DeWalt 20V-1/2" drive cordless drill Counter Clockwise, ( CCW ), engine cranking = Electric Starting! RIGHT SIDE ENGINE CRANKING Only. The CCW OCDT only works with our Avenger 85 and the Skyhawk Gt5A-ES engines that have the special M8-1 left hand thread 10.9 HARDENED Allen Head Cap screw securing the B5 beveled gear that requires counterclockwise cranking. OPERATION: The CCW OCDT locks in the Counterclockwise direction and overruns in the clockwise direction as viewed from the Cordless Drill end. NOTE: By CCW Cranking on a hardened 10.9 M8-1 left hand threaded bolt this ensures no bolt breakage as opposed to cranking on the left side soft magneto nut that strips out easily especially if an impact wrench is used. Words to the wise! Uneducated Competitors say our Gt5A-ES engine is not electric start. Nonsense!!! In automotive applications a 12V Battery supplies DC electricity to a cranking motor ( "Starter" ). Said cranking motor has an overrunning clutch drive pinion. When using a 20V cordless hand tool and our OCDT you have the exact same concept. 20V Battery, Motor and Over-Running Clutch Drive. Hence ELECTRIC STARTING! Our new design OCDT is available in 2 models, one for CCW direction and one for CW direction cranking. Hence, Right side and Left side engine cranking. For a CW cranking OCDT see the another ad. SkyHawk Gt5A-ES & Avenger 85 engines use this CCW OCDT with a M6 Hex 1/2" drive socket bit for Right side engine cranking through the swing door hole to the beveled gear M8-1 ccw left hand Allen Head cap screw. For all other China Doll engines use a CW OCDT with a hex socket for Left side engine cranking off the magneto rotor nut. See listing in another ad. This new OCDT design uses a one-way needle bearing instead of a ball bearing. Needle bearings provide a higher lock torque spec than do ball bearings yet provide a very smooth transition to overrun when the engine starts. NOTE: It has been brought to our attention by knowledgeable engine builders that there are cheaply made in China hand ratchet adapters on the market but they will soon break when the engine lights off. Maybe good for a 1/2 dozen cranks then throw'em in the trash bin. A ratchet does not work the same as the smooth operation of one-way bearing. OCDT is an "Over Running Clutch Drive Tool" for starting engines with a 20V 1/2" / 13mm cordless drill or can use a standard wall plug in 1/2" 110V AC drill. 20V 1/2" cordless Impact wrenches can also be used if they have been modified to eliminate the hammer affect. DO NOT USE A HAMMER DRILL or an Impact wrench unless they have been modified to eliminate the hammer affect. Why use an OCDT? If just using a drill with a M6 Allen hex bit, you run the risk of damaging your drill not to mention possible self-injury when the engine starts. The OCDT ensures safe smooth start up when the engine fires up. It does the same job as a starter drive in your car's 12V starter. The OCDT 10mm hex shank end fits a M10 socket that can work with a Modified 1/2" Impact Wrench or can chuck directly into a 20V Battery powered 1/2" chuck CORDLESS DRILL. DON'T USE A 1/2" DRIVE IMPACH WRENCH UNLESS THE HEAD FLAPPERS HAVE BEEN WELDED STATIONARY AS THE JACKHAMMER AFFECT WILL DAMAGE ONE-WAY BEARINGS. Heads up: If the jackhammer effect ON A 1/2" IMPACT WRENCH is eliminated by tack welding the 2 flappers inside the head so they cannot move it is perfectly alright to use it. See pics. The power and RPM of a Cordless Electric Impact 1/2 drive wrench exceeds that of the cordless drill and is actually the preferred starting method. Please understand that if you order the wrong OCDT version the return shipping both ways shall be paid for by the buyer.
