Reassembly

31. Check valve installed height if valve seats have been refaced or renewed. l Valve installed height, end of valve to base of spring seat, 'A' = 44.16 to 45.29 mm (1.74 to 1.80 in).

32. Reface valves as necessary. If a valve has to be ground to a knife-edge to obtain a true seat, renew valve.
33. Cut valve seats using suitable cutters: l Valve seat angle 'A' = 45°. l Valve seat insert diameter 'B' Inlet = 36.83 mm (1.45 in). l Valve seat insert diameter 'B' Exhaust = 31.50 mm (1.24 in). l Seating width 'C' - Inlet = 0.89 to 1.4 mm (0.035 to 0.055 in). l Seating width 'C' - Exhaust = 1.32 to 1.83 mm (0.052 to 0.072 in). l Angle 'D' = 70° . l Angle 'E' = 46° to 46° 25'. l Angle 'F' = 20° .

middle of blade contacts area of material to be cut. Use light pressure and only remove the minimum of material necessary.
