4-29. Rear Winch Assembly. - ContinuedNOTEBrake cylinder assembly must be pressure tested to ensure proper piston movement and oil tight seals.(9) Test brake cylinder assembly (60) as follows:(a)(b)(c)(d)(e)Using suitable air pressure source, apply 2,500 psi of air pressure to cylinder assembly (60) and releasepressure.Piston should move approximately 1/8 in. (0.318 cm).Repeat Steps (a) and (b) three times to ensure proper operation of piston.Apply 2,500 psi of air pressure and hold pressure in cylinder assembly (6) for 10 minutes. If cylinder assem-bly does not hold pressure, disassemble and check piston, packings, and back-up rings for nicks orscratches.Repair or replace components as needed, reassemble and retest cylinder assembly (60).Figure 4-24.
