42 486 PL ENGINE P If taper and ovality is found to exceed specified limit or bore dimension is not as specified, Machine bore to next over size Criteria to choose the bore size : l Bore diameter of worn out cylinder bore. l Size of next piston available. l Recommended clearance between piston and bore. l Required bore diameter. NOTE : 0.050 to 0.070 mm stock should be left for honing. CAUTION : Maintain the parallality of cylinder bore axis and perpendicularity to axis of crank shaft Clean block & all passages thoroughly Check water jackets and oil passages for leakage at air pressure 5 bar, under water. If block is to be stored apply grease to machined surfaces. CYLINDER HEAD Mating Surface Using a straight edge and feeler gauge, check cylinder head mating surface with crank case. Fig. 92 & 93 If unevenness exceeds permissible limits, replace cylinder head. CAUTION : CYLINDER head top and bottom surface re-machining in service is NOT permitted. Fig. 93 Fig. 92
