One of the repaired Jacking Equalization cylinders is positioned for hookup to a crane.

At the crawler parking area, one of the repaired Jacking, Equalization and Leveling (JEL) cylinders is positioned for hookup to a crane. The crane will lift the JEL for placement in Crawler Transporter No. 2. There are 16 cylinders and 32 bearings per crawler. During recent routine maintenance inspections, technicians removed two of the 16 JEL cylinders on the crawler to gain access to the bearings and found three of the four bearings cracked. Further eddy current inspections indicated that cracks were present on 15 of the bearings. Technicians have removed and replaced 14 of the bearings on CT-2, which is being repaired in order to enable Atlantis' rollout for mission STS-112, scheduled for launch no earlier than Oct. 2.
