●Take care not to tilt or lean the reamer in the guide
while reaming.
●Otherwise, the valve is installed slanted, that causes oil
leaks from the stem seal and improper valve seat
contact and results in the valve seat refacing not able
to be performed.
●Use cutting oil on the reamer during this operation.
●Rotate the reamer clockwise, never counterclockwise
when inserting and removing.
