To Remove Valves
Fig. 2 shows the three methods used to hold the valve
spring retainers. To remove types shown in Illus. 1 and
2, use 19063 compressor; adjust jaws until they just
touch the top and bottom of the valve chamber. This will
keep the upper jaw from slipping into the coils of the
spring. Push the compressor in until the upper jaw slips
over the upper end of the spring. Tighten the jaws to
compress the spring. Fig. 3. Remove collars or pin and
lift out valve. Pull out compressor and spring. Fig. 4.
