Specially designed to be used in conjunction with our SI Pinion/gear press extractor tool (not included)- allows for pinion removal and installation on sealed can motors ( motors that do not have a protruding motor shaft on the back side like NSR, SlotIt and other performance motors) the magnetic side keeps the spacer sleeve in place while operating the tool, no more fumbling and extra third hand needed!
Depicted SI tool, motors, spare hand etc...not included.
