Camshaft bushings are identified in sequence,
1 to 7, starting from the front of the engine.
1. Using camshaft bushing remover/installer
J 42377 (with J 21428-01 Cam Bushing
Installer Set) and a hammer, remove the
No. 1 camshaft bushing from the cylinder
block. Refer to Figure 199.

2. Remove the remaining six bushings in
sequence.
If the camshaft bushings are being replaced in
the chassis, a special tool is required to remove
the No. 7 camshaft bushing. The tool is included
with the J 21428-01 kit. The No. 7 cam bushing
removal tool consists of a bushing puller
(J 21385-1), a cone (J 21385-4), a threaded
mandrel (J 21248-4) and a guide (J 21428-4).
These parts are threaded onto the handle
(J 21099-9), and a slide hammer is then used to
remove the bushing.
