TM 9-2815-210-34-2-2 FRAME 2 NOTE Readings must be within limits given in table 4-27. The letter L shows a loose fit. If readings are not within given limits, throw away part and get a new one. Valve tappet bores (1) and valve tappets (2) are called by numbers one to 12 counting from front to rear of crankcase. Valve tappets were tagged with numbers during engine disassembly. Some early model engines used valve tappets with curved bottoms. Late model engines use valve tappets with flat bottoms. 1. Check whether valve tappets (2) have flat or curved bottoms. Use wear limits in table 4-27 for valve tappets you are working on. 2. Measure inside diameter of 12 tappet bores (1) and outside diameter of 12 valve tappets (2). 3. Measure fit of each of 12 valve tappets (2) in proper valve tappet bores ( 1). END OF TASK 4-119
