  OCDT  "Over Running Clutch Drive Tool" for hand held 20V cordless tool starting.

Heads up:  Our OCDT is only sold to those who have purchased our (ES) easy start engines in the past or have included one with a new purchase.    It only works with our ES or SR engines.   If an OCDT is ordered without having an engine to use it on we will have to cancel your order due to limited OCDT stock on hand.    

 This tool ONLY works with a Gt5A-ES model SkyHawk and GT3-SR SuperRat Engines that have a CCW M6 hex head Crankshaft screw accessible by way of a swing plate on right side of the engine.

This OCDT is an "Over Running Clutch Drive Tool" for starting Gt5A-ES 66cc and StarFire ES 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 that have been modified to eliminate the hammer affect.  

DO NOT USE A HAMMER DRILL or a Impact wrench unless they have been modified . 

Why use an OCDT?    If just using a drill with just a M6 Allen hex head bit you run the risk of damaging your drill not to mention possible self injury.   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 starter. 

NOTE:  Cranking Direction is CCW     If you set your drill or modified impact wrench for CW rotation nothing will happen as the OCDT will just overrun.  

OCDT has a 6mm hex bit drive for starting all SkyHawk Gt5A-ES and SuperRat Gt3-SR70 2 cycle engines. 

10mm hex shank; use 1/2" AC ELECTRIC or 20V Battery powered 1/2" chuck CORDLESS DRILL.  

DON'T USE AN IMPACH WRENCH AS THE JACKHAMMER AFFECT CAN WILL DAMAGE THE ONE-WAY BEARING LOCK MECHANISM.  Heads up:  However, if the jackhammer effect is eliminated by welding the 2 flappers inside the head so they cannot move it is perfectly alright to use a 1/2" drive impact wrench with a 10mm long neck socket that is JB welded onto the 10mm hex shaft of the OCDT.   See pics.  The power and RPM of an Cordless Electric Impact 1/2 drive wrench much exceeds that of the cordless drill and is actually the preferred starting method. 

 Uneducated Competitors say our engine is not electric start.   Nonsense!!!  In automotive applications a 12V Battery supplies DC electricity to a cranking motor ( Starter ) used to crank the engine for starting.    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.   ELECTRIC STARTING!
