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

the cover (2). See Fig. 12. Slide the washer (18) onto

5. Grease the detent link (22) and link spacer (17).
Assemble the detent link, link spacer, and actuator link
(16) as shown in Fig. 13. 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).
