SPRING BUSHING REPLACEMENT
Small Bushing
(1) Insert 3/8 by 8 inch (0.95 by 20.3 cm) length of
threaded rod halfway through bushing.
(2) Place suitable size socket on one end of rod with
open end of socket toward bushing. Socket will serve as
bushing driver.
NOTE: The socket must be large enough in diameter to
bear against the metal outer sleeve on the bushing but
still be small enough to pass through the spring eye.
(3) Install one flat washer and one hex nut on rod
behind socket (fig. 2N-9).
(4) Install 2 inch (5.08 cm) long section of suitable
size pipe on opposite end of threaded rod. Pipe will serve
as bushing receiver.
NOTE: The inside diameter of the pipe must be large
enough to accommodate the bushing but still seat
against the spring eye surface properly.
(5) Install flat washer and hex nut on rod to secure
pipe section. Be sure flat washer is large enough in
diameter to support and maintain alignment of pipe
section.
(6) Tighten both hex nuts finger-tight and align all
components.
NOTE: Be sure socket is positioned in the spring eye
and aligns with the bushing. The pipe section must butt
against the spring eye surface so the bushing can pass
through it. The socket will act as a press ram and press
the bushing out of the spring eye.
(7) Tighten nut at socket end of rod until bushing is
pressed out of spring eye.
(8) Remove bushing tools and old bushing.
(9) Install replacement bushing on threaded rod.
(10) Assemble and align bushing tools as outlined in
previous steps.
(11) Align bushing with spring eye and press bush-
ing into eye.
(12) Loosen bushing tools and check bushing posi-
tion. Bushing must be centered in spring eye. Ends of
bushing must be flush or slightly below side surfaces of
spring eye.
(13) If bushing is not centered, reinstall bushing
tools and correct bushing position as necessary.
