BELLCRANK CENTRE BUSH REMOVE AND REPLACE
Early
type bushes are one piece; later - type comprise
three pieces. The best way to remove and replace
the bush is by using special puller supplied by
Muldoon Transport Systems (tool number BC
BU-1-3) The use of this puller means the
bush can be changed without removing the
Bellcrank (FIG 29a and 29b).

FIG 29b |
The
puller is made to fit the end of the bush, which
stops the bush being distorted during the
process of removing or replacing it; also, this
tool ensures the bush is easily centralized. The
later - type bronze bushes should easily lift
out: one from the top, and one from the bottom.
NOTE
(early and later type bushes are not the same
diameter)
Puller
is supplied with all necessary parts to remove
and replace both types.
NOTE
It is highly recommended that the "0"
rings are discarded when replacing bronze
bushes; this will
allow grease to penetrate better.
