loctite is dry.
4.
Insert the shaft through the bushings and check again for friction.
Orientate the shaft as per parts draw ing.
5.
Mark valve and body, to assure that each time you remove the valve
you insert it in the same orientation. Insert the valve and place it on

Press the valve w ith your fingers dow n on the shaft and rotate the
shaft to check fit of the valve to the body in both valve positions. The
valve w ill need to be filed to allow for proper seating in the body.
