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.
