Removal and Installation
Removal
To replace service seat inserts, machine the insert in the same manner as if machining out the internal seat. Hold the same tolerances and follow the same
installation procedures.
Installation
Inspect the valve guide bores as described in the Cleaning and Inspection section of this group. If it is necessary to install valve guides, install the guides
before installing the service seats.
Replacement valve seat inserts must be installed if the valve seats have been ground previously. The illustrated marks indicate valve seats have been
ground previously.
