| -2- Oy4-E-11123 in conjunction with a pin which is slightly heavier, but 3-1/2 times as stiff as pin E-17765. This increased stiffness we believe is desirable because pin E-17765 gave us a little trouble through spreading out at the sides and thus in time hammering loose in the piston boss. We attach prints of pin E-17765 with reduced bore and of lock screw E-17766 for convenient reference. Oy. M.{Mr Moon / Mr Moore} Olley MO/E COPY | ||
