On Minarelli engines or copies thereof, it can easily happen that one knocks the seals at the crankshafts too far in, thereby mistakenly blocking the lubrication channels. This results in faulty crankshaft bearings in record time, which is the last thing you want after installing a new crankshaft in your engine block.
Easyboost has solved this problem with this cleverly designed tool so that you cannot push the seals too far into the block and thereby guarantee a perfect installation, every time. The tool fits perfectly around the edge of the seals and the built-in elevation ensures that you do not drive the crankshaft seals too far into the block, as the tool goes on the edge of the block before the accident occurs.
