Most owners of classic Harleys know this problem: in springtime, after a long garage period, you start your motorcycle and immediately watch a puddle of oil building underneath the machine. The crankcases had filled with oil from the tank and now get rid of it through the venting system. With this tool, you can re-cut the ball seats of the check- and relief valve and thus again ensure a proper fit of the steel balls in the oil pump to prevent oil from bleeding through the oil pump. This hand tool comes with 2 adapters, one of them suitable for the threads of the check valve and the other for the threads of the relief valve.
