![]() ![]() Using a bore gauge, measure cylinder bore in X and Y directions at A, B and C for wear, out-of-round and taper. If resistance is felt, cylinder head must be replaced. The maximum limit: A + B = 0.07 mm (0.0028 in) After resurfacing cylinder head, check that camshaft rotates freely by hand. Amount of cylinder block resurfacing is “B”. Resurfacing limit: Amount of cylinder head resurfacing is “A”. The limit for cylinder head resurfacing is determined by the cylinder block resurfacing. Head surface flatness: Limit 0.1 mm (0.004 in) If beyond the specified limit, resurface or replace it. Check along six positions shown in the figure. Use a reliable straightedge and feeler gauge to check the flatness of cylinder head surface. 19 Crankshaft.19 Available Connecting Rod Bearing.19Ĭlean surface of cylinder head. 15 ZD SERVICE DATA AND SPECIFICATIONS (SDS). 14 Cylinder Block.15 Piston, Piston Ring and Piston Pin. 12 Inspection.12 YD SERVICE DATA AND SPECIFICATIONS (SDS). 8 Inspection.9 CYLINDER HEAD.10 Inspection.10ĭisassembly and Assembly.10 Inspection.10 CYLINDER BLOCK. 5 Inspection.5 VALVE CLEARANCE INSPECTIONS AND ADJUSTMENTS.7 Adjustments.
