Suzuki GSX-R750 (1993-1995) [65/352] Cylinder head distortion

Содержание

ENGINE 3 22 CYLINDER HEAD DISTORTION Decarbonize the combustion chambers Check the gasketed surface of the cylinder head for distor tion with a straightedge and thickness gauge taking a clear ance reading at several places indicated If the largest reading at any position of the straightedge exceeds the limit replace the cylinder head 09900 20803 Thickness gauge Service Limit 0 2 mm 0 008 in VALVE STEM RUNOUT Support the valve with V blocks as shown and check its runout with a dial gauge The valve must be replaced if the runout exceeds the limit 09900 20606 Dial gauge 1 100 mm 09900 20701 Magnetic stand 09900 21304 V block 100 mm Service Limit 0 05 mm 0 002 in VALVE HEAD RADIAL RUNOUT Place the dial gauge at right angles to the valve head face and measure the valve head radial runout If it measures more than the limit replace the valve 09900 20606 Dial gauge 1 100 mm 09900 20701 Magnetic stand 09900 21304 V block 100 mm Service Limit 0 03 mm 0 001 in VALVE FACE WEAR Visually inspect each valve for wear of its seating face Replace any valve with an abnormally worn face The thick ness D decreases as the wear of the face advances Measure the thickness and if the thickness is found to have been reduced to the limit replace it 09900 20102 Vernier calipers Service Limit J 0 5 mm 0 02 in VALVE STEM DEFLECTION Lift the valve about 10 mm 0 39 in from the valve seat Measure the valve stem deflection in two directions X and Y perpendicular to each other by positioning the dial gauge as shown If the deflection measured exceeds the limit see below then determine whether the valve or the guide should be replaced with a new one 09900 20606 Dial gauge 1 100 mm 09900 20701 Magnetic stand Service Limit Intake and exhaust valves 0 35 mm 0 014 in
