NOTE: After completing the Yoke Reassembly, go directly to the
section on ADJUSTING THE FIRST STAGE on pg 12.
CAUTION: The handwheel connector must be held verti-
cally while being installed upwards into the body until snug.
Failure to do this can cause the o-ring not to seat properly
which in turn will create a high pressure leak.
