Clean and Inspect the Parts

13.Inspect the cylinder tube and piston for scratches. Replace if necessary.

14.Using a clean, dry cloth, remove any grease from the inside of the tube, the outside of the piston, and the cylinder rod.

15.Remove the two cylinder block o-rings from the blocks and replace.

16.Remove the piston o-ring and replace.

17.Remove the cylinder rod from the rod end block.

18.Remove the rod o-ring from the rod end block and replace.

19.Liberally apply high temperature lubricant grease (part 115982) to the inside of the tube, the outside of the piston, all the o-rings, and the cylinder rod.

Re-Assemble the Air Cylinder

NOTICE

In the following step, the long screws must be tight- ened in a crisscross pattern. Failure to do so may result in air cylinder damage.

20.Reinstall the four long screws that attach the two drive blocks by finger-tightening them. Then torque
