Check Valves
A major concern and problem area with Triples is with
oil line check valves. Defective check valves
can leak causing excessive smoking or even bent rods from hydrolocking.
Stuck valves can prevent cylinder oiling. The spec for crack pressure was
increased from early (pre '74) valves from 2.8psi. Early check valves can
easily be disassembled and cleaned.
New springs are now available along with new check balls for early check
valves from members of the KTOG message board. This eliminates the need to
make a test setup and reset springs for proper crack pressure.
Newly manufactured check valve springs are made from phosphor bronze
averaging 4.5 to 4.7 PSIG relief pressure. These springs have the small
diameter on one end to "hold the check ball". Stock outside diameter and
inside diameter and stock wire size.
New Chrome Steel check balls 0.125” (stock) diameter.
