Use only the tool (94291, Fig. 3) to grind the
valve seats.
1) Read the data in the manufacturer’s
documentation for the tool (94291).
2) Put the valve seat (1) in the correct
position on the tool (94291).
3) Put the gauge (94279) on the valve
seat (1, Fig. 4).
The data on the gauge (94279) shows the
maximum permitted limits for the valve
seat (1).
4) Use the feeler gauge (94122) to
measure the values. If the measured
values are more than the limits shown,
you must replace the valve seat (1).
5) If the measured values are less than
the values given, do the procedure that
follows:
a) Use the tool (94991) to grind the
sealing face of the valve seat (1).
Make sure that you get a smooth,
flat surface.
b) Keep the valve seat angle to
between 30.0° and 30.2°.
