c. Installing valve grip.
(1) Place grip safety, valve lever, and rocker arm in position in right valve grip. ([Fig 48]) Be sure the shorter end of rocker arm is at the top. Place grip spring over spring pin. Slip short end of grip spring in groove of rocker arm. Place long end of grip spring on outside of grip safety.
