The taper on the inside of this tool eases the transition of the o-ring into the groove in the rocker box, and without it, the o-ring typically gets cut or shaved when pushing the rocker shaft into rocker box. The taper allows the o-ring to be installed, undamaged, resulting in a leak-free install.
