CONNECTING ROD BUSHING REPLACEMENT
Connecting Rod Bushing Replacement
Connecting Rod bushings (small end) 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 connecting rod on the base
of the arbor press such that the small
end bushing bore of the connecting rod
is directly supported and the bushing
can be freely pressed from the
connecting rod.
NOTE:
Avoid supporting the connecting rod in
such a way that bending loads are
placed on the length of the connecting
rod in order to prevent damage to the
connecting rod.
(2) Insert the tool in the connecting rod
small end bushing so that the shoulder
of the tool rests on the edge face of the
bushing and is clear of the ID of the
connecting rod bore
(3) Press out connecting rod bushing.
(4) Clean connecting rod thoroughly as
described in the Cleaning section of this
manual and inspect the condition of the
connecting rod bushing bore. Repair
scratches as required per the Cleaning
section of this manual.
Assemble a new connecting rod bushing using
the arbor press and extraction/insertion tool
described above as follows:
(1) Support the connecting rod on the base
of the arbor press such that the
connecting rod bushing bore is directly
supported.
NOTE:
Avoid supporting the connecting rod in
such a way that bending loads are
placed on the length of the connecting
rod in order to prevent damage to the
connecting rod.
(2) Insert the tool in the bushing so that the
shoulder of the tool rests on the edge
face of the bushing and is clear of the ID
of the connecting rod bore
(3) Insert bushing until the bushing is
centered within the bore of the
connecting rod and bushing is flush with
the sides of the connecting rod.
(4) Broach the bushing ID to size per the
Fits and Clearances section of this
manual.
