Feeler Gauge MethodFigure 7 - 15MEASURE PISTONAT THIS AREAJ8909-31(Not recommended for racing.)a. Remove the rings from the piston.b. Insert a long 0.013 mm (0.0005") feeler gauge intothe cylinder bore.C. Insert the piston (top first) into the cylinder borealong side the feeler gauge. With the entire pistoninserted in the cylinder bore, the piston should notbind against the feeler gauge.d. Repeat the above procedure with a long 0.051 mm(0.002") feeler gauge. The piston should bind.e. If the piston binds on the 0.013 mm (0.0005")feeler gauge, either the piston is too large or thecylinder bore is too small. If the piston does notbind on the 0.051 mm (0.002") feeler gauge, thepiston may be enlarged by hurling or shotpenning.Replace any piston that is 0.102 mm(0.004") or more undersize.Piston Ring FittingCaution: DO NOT remove metal from the grooves orlands. Doing so will change the ring groove clearances andwill destroy the ring-to-land seating.1. Carefully clean carbon deposits from all the ringgrooves. Ensure the oil drain openings in the oil ringgrooves and pin boss are open.2.3.4.5.6.7.Measure the ring side clearance with the correct sizefeeler gauge that fits snugly between the ring land andring (Figure 7-16). Slide the ring around the groove. Itmust slide freely around the circumference of thegroove. Refer to 360 AMC V-8 Engine Specifications,'Engine Assembly' section of this chapter, for thecorrect ring side clearance.Place the ring in the cylinder bore. Use an invertedpiston to push the ring down near the lower end of thering travel area. Measure the ring gap (clearance) witha feeler gauge fitting snugly in the ring opening. Referto 360 AMC V-8 Engine Specifcutions, 'EngineAssembly' section of this chapter, for the correct ringgap (clearance).Install the oil control rings according to the instructionsin the package. Roll the upper and lower rails intoplace without the use of a tool (Figure 7-17).Install the bottom compression ring using the ringinstaller to expand the ring around the piston. Installthe top compression ring using the ring installer toexpand the ring around the piston.Ensure the top and bottom compression rings areinstalled properly. Ideally, the ring gaps should bespaced 180" from each other.Ensure the top and bottom compression rings areinstalled with the top side up.Figure 7 - 16J8909-41
