32.Valve Seat Cutter Set (5SL-M1112-70)

This tool set is used for fine adjustment of the contact of the valve and valve seat.

• This set includes 3 specifications each of the diamond cutters for INT and EXT.

• When doing cutting operation, apply engine oil to the cutting surfaces.

• If the valve cannot be completely worn in through rubbing, cut the contact surface of

the seat with a 90 deg. cutter and do the rubbing again.

• Check the contact area and width of the valve and seat. If there is 1 mm-wide rubbed

area in the center of the 90 deg. surface of the valve, no correction is needed. If it is

off to either side, or if there is a rubbed area more than 1.1 mm wide, adjustment

should be performed.
