1. Clean and inspect all parts IAW General Maintenance Instructions (WP 0019).
CAUTION
Do not clean or reuse O-rings.
Do not use abrasive material to clean cylinder sleeves. Failure to follow these instructions
may result in damage to the equipment.
2. Remove O-ring (Figure 3, Item 3), shim(s) (Figure 3, Item 2) (if equipped), and two black packing O-rings
(Figure 3, Item 4) from cylinder sleeve (Figure 3, Item 1). Discard O-rings.
3. Measure inside diameter of sleeve (Figure 3, Item 1) with an inside micrometer or bore gauge from top to
bottom of sleeve where it is subject to piston and ring travel. Take measurements at right angles to determine if
sleeve is out-of-round or excessively tapered. See Table 1 for maximum allowable sleeve wear. If sleeve does
not meet specifications it must be discarded and a new piston sleeve (and piston) installed.
