(9)
Insert valve ball (10) into housing (13) with shaft flats (37) on ball aligned with shaft holes in housing.

Place O-ring (23) into groove in inside end of attaching-cable-side shaft (19) and insert attaching-cable-side
shaft (19) into housing (13) and ball (10).
NOTE
It is normally possible to install the valve ball without regard to left-right or front-
rear position. Occasionally, however, a ball will not be perfectly machined and the
operating shafts will engage in one position only. If this problem occurs when
installing the shafts, it will be necessary to remove the valve ball and install in a
different position to allow the shafts to align properly for engagement with the
valve ball.
(12)
Install bushing (17) onto the handle-side shaft (12). Lightly lubricate O-ring (15) with petrolatum and install
bushing (16) and O-ring (15) onto handle-side shaft (12). Place O-ring (14) into inside end of groove in
handle-side shaft (12) and insert handle-side shaft (12) into housing (13) and valve ball (10). If handle-side
shaft (12) will not mate with ball (10), remove handle-side shaft (12), rotate ball (10) and insert handle-side
shaft (12). Install retaining screw (11) to secure handle-side shaft (12) to valve ball (10). Hold valve ball
(10) with fingers while tightening screw (11).
