360-Degree Adjustable Arms:


Features three adjustable full 360-degree arm rotation for complete adjustability, it can be used on a variety of bolt patterns and for almost any 2 & 4 stroke crankcases.

The arms fit an array of different bolt patterns, so the 3-leg frame is appropriate for many applications. This versatile splitter/separator tool is a necessity in your toolbox..


Please refer to above video for Demo!


Step 1: Place center of splitter/Separator over exposed crank end. Back out threaded shaft until the splitter sits over crank and arms are parallel and equal distance from case. 

Step 2: Using supplied 6mm or 8mm bolts, attach splitter arms evenly spaced around the crank and attach arms to the crankcase. (Occasionally only two arms will be needed; if so, space evenly.)  

Step 3. It is important that the splitter is properly aligned with the crank and the arms are parallel with the case. 

Step 4. Make sure all bolts are removed from the crankcases. 

Step 5. Using a 17mm socket or wrench, carefully tighten threaded shaft until case clears crank. 

Important: as the bike has been together for a while, things could get stuck together, you need to be very careful, not only make sure to apply the force evenly and gradually increase the force (trick is to use small hammer give a gentle taps), otherwise, you will risk breaking the splitter's arms or your crankcase.

Step 6. Disassemble tool from crankcase.
