Removing EGR Valve
• The EGR puller must be used when
removing the EGR valve or the valve and
intake manifold may be damaged.
• To remove the EGR valve, first remove the
EGR valve mounting bolts that hold the
valve to the intake manifold.
• Rotate the valve counterclockwise until the
pins at the ends of the EGR puller arms
will slip under the EGR valve housing tabs
and into the holes. Hook the other end of
the puller arms to the puller beam. Position
the other two arms over the holes in the
intake manifold. Turn the shaft clockwise to
remove the EGR valve.
Injector Removal
• After removing the valve cover, remove the
rear port plug. The port plug may pull the
case-to-head tube from the branch
tube assembly. Remove the seven bolts
that hold the oil rail to the rocker arm
carrier. Pull the rail from the head.
• Oil is not drained from the rail prior to
removal, so oil will leak from the rail as it
is removed.
•
Note:
The port plug and case-to-head
tube's O-rings are not replaceable. The
port plug and case-to-head tube must be
replaced if the O-rings are damaged.
Injector Connectors
• The injector connectors on the VT 275
pass through the rocker lever carrier.
Disconnect the injector harness from the
injectors by depressing the metal bail on
the harness connector body while pulling
the harness connector from the injector.
To remove the injector pass-through
connector, use the Injector Connector
Remover (ZTSE4650) or push the open
end of a 12-point 19mm socket over the
connector to release the clips. Carefully
pull the connector body from the carrier.
The injectors will be extracted when the
injector hold-down clamp bolts are
removed.
