TM 5-3805-261-34 ENGINE MAINTENANCE. (cont) 13-3. Cylinder Head Assembly Overhaul. (Sheet 5 of 6) INSPECTION/REPAIR (cont) 8. Inspect valve seats on combustion surface. Remove and replace if cracked or badly burned. Refer to paragraph 3-12. 9. Inspect combustion surface for erosion. Check combustion chamber fire ring, oil passages, bolt holes and outer casting surface. If erosion has reduced any of these areas to 0.16 inch or less, you must grind the combustion surface. WARNING Wear safety goggles and respirator when grinding. Failure to follow this procedure may result in SERIOUS INJURY. If injured, seek medical aid immediately. NOTE Cylinder head may appear streaked or discolored after grinding. This appearance is normal and does not indicate any defect in either the material or reconditioning procedure. New cylinder heads from the factory may also have the same appearance but are completely satisfactory for use. 10. Using stone or equivalent, grind smooth all gas and coolant errosion on combustion surface (Figure 13-10). Figure 13-10. Go to Sheet 6 13-14
