new and larger valves obtained. The

materially. Some use an aluminium al

take the old pistons and drill holes In
them. Each piston should weigh the

You should replace the lost ball with
new one, taking particular care to
obtain the exact size, so that all the
balls of the bearing will be of the same
size. IL you do not replace the lost
ball the additional strain put upon the
others due to the lost one. may cause
