How to Install Push Rod on Firewall Mounted Boosters
Grab push rod in a vice leaving a small space
between the hub and vice.
Slip 2 screwdrivers between the hub and vice
then pry the hub away from the vice (Pry
easy to prevent cracking the hub.) The push
rod should slip out.
Slip the new plastic lock ring onto the slot at the
end of the push rod.
Slip push rod and lock ring into the hub. Push
and move push rod from side to side until the
lock ring catches in place (do not use hammer
