Workers accompany the JEL cylinder as it is moved from the repair site for installation into Crawler Transporter No. 2.

Workers accompany the repaired Jacking, Equalization and Leveling (JEL) cylinder as it is moved from the repair site for installation into 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.
