1.1 CYLINDER BLOCK AND CYLINDER LINER 5. Install the water inlet cover plate (J–36223–7A, part of tool set J–36223–D). See Figure 1-11. Use the bolt supplied with the tool to secure it to the cylinder block. Figure 1-11 Water Inlet Cover Plate Installation NOTE: At the base of each liner, the space between upper and lower liner seals is vented to the block surface on the left side. Any coolant leakage past the upper seal is drained to the outside rather than into the crankcase, and is easily detected by a visual inspection. 6. With a suitable lifting device and spreadable bars, immerse the cylinder block for twenty minutes in a tank of water heated to 82-93°C (180-200°F). 7.
Attach an air line to the water inlet cover plate and apply 138 kPa (20 psi) air pressure to the water jacket. Observe the water in the tank for bubbles that will indicate cracks or leaks. A cracked cylinder block must be replaced by a new block. EYE INJURY To avoid injury from flying debris when using compressed air, wear adequate eye protection (face shield or safety goggles) and do not exceed 276 kPa (40 psi) air pressure. 8. Remove the block from the water tank. Remove the plates and gaskets and blow out all of the passages in the block with compressed air. 9. Install the cylinder block to the engine overhaul stand (J–29109). See Figure 1-6. (Rev.
