Valve stem deflection Support the valve with V blocks as shown and check its deflection with a dial gauge The valve must be replaced if the deflection exceeds the limit Valve stem deflection specification If the valve stem is worn down to the limit as measured with a micrometer where the clearance is found to be in excess of the limit indicated above replace the valve if the stem is within the limit then replace the guide After replacing valve or guide be sure to recheck the clearance Valve stem diameter specification Valve Intake valves Exhaust valves Valve to guide clearance Measure the clearance in two directions X and Y perpendicular to each other by rigging up the dial gauge as shown If the clearance exceeds the limit specified below then determine whether the valve or the guide should be replaced to reduce the clearance to the standard range Valve to guide clearance specification Valve Intake valves Exhaust valves Standard Service limit 0 025 0 055 mm 0 090 mm 0 0009 0 0022 in 0 0035 in 0 040 0 070 mm 0 100 mm 0 0016 0 0028 in 0 0039 in 7 20 Service limit 6 960 6 975 mm 6 90 mm 0 2740 0 2746 in 9 271 in 6 945 6 960 mm 6 80 mm 0 2734 0 2740 in 0 267 in Fig 7 69 Valve seat width measurement Coat the valve seat with red lead paste un iformly Fit the valve and tap the coated seat with the valve face in a rotating manner in order to obtain a clear impression of the seating contact In this operation use the valve tapper to hold the valve head Fig 7 70 Fig 7 68 Standard
