(20) Wipe away any excess lubricant or sealing compound
that may be in either injector sleeve bore (1) or in

reamer assembly comes in contact with guide
If injector seat does not match to 360 full face,
injector sleeve must be removed. Install new
injector sleeve and do reaming procedure again.
Stop cutting immediately when seat is full face,
so minimum amount of material is removed.
This way, as much material as possible will be
retained, in the event that reaming is necessary

For correct sealing of combustion gas, injector
seat must be free of machining chatter and
(24) With light but even pressure, turn reamer assembly (12)
(25) Remove reamer assembly (12) and guide bushing (5)
