2. Grease the spring (6) and place it in the collar (7).
Grease the ball (8) and set it on the spring.

in the cover (2). See Fig. 7. Slide the washer (18)

5. Grease the detent link (22) and link spacer (17).
Assemble the detent link, link spacer, and actuator
link (16) as shown in Fig. 8. The raised bumps on
the links (22 and 16) must face up.
6. Squeeze the spring (3) and install it and the stop
(4) in the link assembly. The spring tension will
hold all these parts together. Grease the valve cup
(5) and install it in the link assembly as shown.
7. Install the link assembly on the cover (2) so the
pointed end of the reset shaft (21) fits through the
holes in the links and the square part of the shaft
engages the square hole. Make certain the bumps
on the detent link (22) engage the ball (8).
