wear eyeshields may result in injury to personnel.
1. Clean cylinder head (3) with compressed air.
Drycleaning solvent is flammable and will not be used near open
flame. Use only in well-ventilated places. Failure to do so may
result in injury to personnel.
2. Clean cylinder head (3) openings and ports with brush and drycleaning solvent. Dry with
compressed air.
d. Installation
CAUTION
Valve seat inserts may be installed one time only. If valve seat
insert is not properly installed the first time, a new valve seat
insert must be installed. Reinstalling valve seat inserts will result
in damage to equipment.
NOTE
Keep valve seat inserts in cold storage until ready to install in
cylinder head. Install valve seat insert very quickly so room temp-
erature does not expand valve seat insert making it difficult to
install.

head (3).
2. Using valve seat insert tool and valve seat insert staking tool, stake valve seat insert (1) into
