ROCKER ARM BUSHING REPLACEMENT
Rocker Arm Bushing Replacement
Rocker bushings that were rejected during
inspection must be removed and replaced as
described in this section.
Use an arbor press and an extraction/insertion
tool (piloted shoulder press tool) to remove the
rejected bushing as follows:
(1) Support the rocker arm on the base of
the arbor press such that the center
bore of the rocker arm is directly
supported and the bushing can be freely
pressed from the rocker arm.
NOTE: Avoid supporting the rocker arm in
such a way that bending loads are
placed on the rocker arms in order to
prevent damage to the rocker arms.
(2) Insert the tool in the rocker arm bushing
so that the shoulder of the tool rests on
the edge face of the bushing and is
clear of the ID of the rocker bore
(3) Press out the rocker arm bushing.
(4) Clean rocker arm bore and oil holes
thoroughly as described in the Cleaning
section of this manual and inspect the
condition of the rocker arm bore. Repair
scratches as required per the Cleaning
section of this manual.
Assemble a new rocker arm bushing using the
arbor press and extraction/insertion tool
described above as follows:
(1) Support the rocker arm on the base of
the arbor press such that the center
bore of the rocker is directly supported.
NOTE:
Avoid supporting the rocker arm in
such a way that bending loads are
placed on the rocker arms in order to
prevent damage to the rocker arm.
(2) Rotate to align the bushing so that the
lubrication hole is aligned with the oil
hole on the pushrod side of the rocker
arm bore.
(3) Insert the tool in the rocker arm bushing
so that the shoulder of the tool rests on
the edge face of the bushing and is
clear of the ID of the rocker arm bore
(4) Insert rocker arm bushing until the
lubrication hole of the bushing is
centered on the oil hole on the pushrod
side of the rocker arm bore and the
bushing is flush with the sides of the
rocker arm.
(5) Ream or hone the bushing ID to size per
the Fits and Clearances section of this
