[. . . ] Use a "Vee" block and the flat side of a grindstone to grind valve clearance. The end of the stem must be flat and true or abnormal wear will occur. EXHAUST VALVE SEAT IN HEAD INTAKE VALVE GUIDE DIMENSIONAL CHECK. Check dimensions per specification requirements, determine if valve guide clearance is beyond acceptable tolerance. If valve guide clearance is worn beyond tolerance, ream valve guide oversize and install 1/32'' (. 787 mm) oversize valve, or replace valve guides. 29 THIS SYMBOL POINTS OUT IMPORTANT SAFETY INSTRUCTIONS WHICH IF NOT FOLLOWED COULD ENDANGER THE PERSONAL SAFETY AND/OR PROPERTY OF YOURSELF AND OTHERS. VALVE GUIDE REMOVAL AND INSTALLATION INSTRUCTION FOR VALVE-IN-HEAD ENGINES. Submerge the head in a pan of oil so that both guides are covered with oil. When the oil begins to smoke, remove the head from the pan of oil with a pair of pliers. Place head on the bed of an arbor press on parallels with the snap rings on the long ends of the guides facing down. Use a 1/2''(25. 4 mm) diameter, 6'' (152 mm) driftpunch and the arbor press to push valve guides out of the head. GUIDES HEAD OIL INSTALLING NEW GUIDES NOTE For easy installation, the replacement guides should be placed in the freezer compartment of a refrigerator or on ice for no less than 30 minutes prior to installation. Submerge head with guides removed in a container of oil so that both guide bores are covered with oil. When the oil begins to smoke, remove the head from the pan with a pair of pliers. See Specifications. TOP PISTON LAND CLEARANCE PISTON 1st COMPRESSION RING CYLINDER WALL SIDE CLEARANCE 3rd OIL CONTROL RING PISTON DIAMETER MEASUREMENT. This is a cam ground piston and the diameter will not be the same when checked at another point. Pistons and rings may be available in either . 010'' (. 254 mm), . 020'' (. 508 mm), . 030'' (. 762 mm) and . 040'' (1. 016 mm) oversize. RING AND WRIST PIN ASSEMBLY. Stagger the piston ring gaps 90° apart when installing piston and ring assembly in cylinder. The wrist pin is a palm press fit (pressed in by hand with some resistance). Replace piston and wrist pin if loose. RING GAPS CHECK PISTON DIAMETER AT THIS POINT RING END GAP MEASUREMENT. Before installing the rings, insert each ring into the cylinder bore to check the end gap. This gap check should be made in a worn cylinder, a reconditioned cylinder and a new cylinder. An inverted piston should be used to push the ring into the cylinder to a point that would be the center of ring travel. Insert the piston ring into the cylinder and place the top side of the piston on the ring to position the ring squarely in the bore; remove piston. Measure the end gap by inserting a feeler gauge between the ring ends.
