MEASUREMENTS - CYLINDER LINER - Continued 3. Check liner inside diameter for taper and out-of-round. Taper must not exceed 0.002 in. (0.05 mm) on used liner and 0.001 in. (0.03 mm) on new liner. Out-of-round must not exceed 0.003 in. (0.08 mm) on used liner and 0.002 in. (0.05 mm) on new liner. NOTE Liners, standard and oversized, have an inside diameter of 3.8752–3.8767 in. (98.430–98.468 mm). Liners are available in 0.010 and 0.020 in. (0.254 and 0.508 mm) on outside diameter. Special liner to block preformed packings are required when using 0.020 in. (0.508 mm) oversize liner. When an oversize liner is installed, stamp amount of oversize on top of cylinder block bore adjacent to liner counterbore using metal stamping die set. 4. Remove liner from cylinder block. END OF TASK FITTING CYLINDER LINER IN BLOCK BORE NOTE If the cylinder liner is used with an unbroken glaze, hone liner before fitting liner to block bore (see Repair). 1. Wipe inside and outside of liner clean. Clean block bore and counterbore thoroughly. 2. Slide cylinder liner (Figure 5, Item 1) into cylinder block bore until liner flange rests on bottom of counterbore in block. Do not drop or slam liner flange against bottom of counterbore in block. 3. Tap liner lightly with soft head hammer to ensure liner flange seats on bottom of counterbore. 4. Install cylinder liner hold-down clamp (Figure 5, Item 6). NOTE Maximum liner height difference of 0.002 in. (0.05 mm) between any two adjacent liners is allowed as measured lengthwise along center line between adjacent cylinders. 5. Measure distance from top of liner flange to top of block with depth cylinder gage (Figure 5, Item 5). Liner flange must be 0.0465–0.050 in. (1.181–1.270 mm) below top of block. 6. If above liner depth limits are not met, use a new liner or install liner in another bore. 7. Matchmark liner and cylinder block on outboard side so liner is reinstalled in same position and same cylinder bore as measured. 8. Remove cylinder liner hold-down clamp (Figure 5, Item 6) and cylinder liner (Figure 5, Item 1). TM 9-2815-205-24 0096 0096-6
