Valve Seating

1. Coat the valve face lightly with prussian blue and put the valve on

its seat to check the contact.

2. If the valve does not seat all the way around the valve seat or the

valve contact is less than 70 %, correct the valve seating as
follows.

3. If the valve contact does not comply with the reference value,

replace the valve or correct the contact of valve seating.

Correcting Valve and Valve Seat

NOTE

■

• Before correcting the valve and seat, check the valve stem

and the I.D. of valve guide section, and repair them if
necessary.

• After correcting the valve seat, be sure to check the valve

recessing.

1) Correcting Valve
1. Correct the valve with a valve refacer.

2) Correcting Valve Seat
1. Slightly correct the seat surface with a 0.785 rad (45 °) valve seat

cutter (Code No. 07909-33102).

2. Fitting the valve, check the contact position of the valve face and

seat surface with prussian blue. (Visual check) [If the valve has
been used for a long period, the seat tends to come in contact
with the upper side of the valve face.]

3. Grind the upper surface of the seat with a 0.262 rad (15 °) valve

seat cutter until the valve seat touches to the center of the valve
face (so that (a) equals (b) as shown in the figure)

4. Grind the seat with a 0.785 rad (45 °) valve seat cutter again, and

visually recheck the contact between the valve and seat.

5. Repeat steps 3 and 4 until the correct contact is achieved.
6. Continue lapping until the seated rate becomes more than 70 %

of the total contact area.
