Step 7. Remove the old stem and stem guide from actuator by gripping the actuator stem with a pair of pliers and
gently pulling the stem guide until the O-ring seal breaks free. The use of pliers to remove the stem will permanently
damage the stem. Discard the old stem and stem guide immediately; these are never to be reused. Ensure that the
placement of the new stem cap is correct; refer to the picture above.
Step 8. Replace the stem and stem guide with the new set that came pre-lubricated in your kit making sure the
guide ribs on the stem guide are positioned into the grooves of the lower casing correctly. Apply Dow Corning
or comparable extreme low temperature lubricant to the tip of the stem. The O-ring on the stem guide should not
be lubricated.
