INSPECTION 1. It is mandatory to use a dial bore gauge (2) to measure each cylinder bore diameter. To correctly 2. Measure the inside diameter of the cylinder bore at three levels below top of bore. Start perpendicular 3. Measure the cylinder bore diameter crosswise to the cylinder block near the top of the bore. Repeat 4. Determine taper by subtracting the smaller diame- ter from the larger diameter. 5. Rotate measuring device 90° and repeat steps above. 6. Determine out-of-roundness by comparing the dif- ference between each measurement. 7. If cylinder bore taper does not exceed 0.025 mm (0.001 inch) and out-of-roundness does not exceed 0.025 mm (0.001 inch), the cylinder bore can be honed. If the cylinder bore taper or out- of-round condition exceeds these 9 - 1224 ENGINE - 3.7L SERVICE INFORMATION WK |
