Brauer/Brower unit won't retract and leaks oil. Help pls

Hi
I accidentally friction welded the drawbar to the end of the brauer unit plunger by powering up the spindle with the plunger down. They have since been separated however now when the command to activate the cylinder is given the cylinder will extend but not retract. I know the problem is with the cylinder itself as I have tested the pneumatic system with a brauer unit from another Triac, which worked fine.
I think that I have damaged the seals by heating up the unit during the accident. I can also see that some oil is leaking from the bottom of the unit- the brown substance in the second photo. Does anyone know what type of oil to top up the unit with and how to disassemble the unit to investigate further? The socket head cap screw in the photo just turns the whole plunger when I turn it. I can see a circlip at the bottom of the unit but I can't separate the threaded body of the cylinder from the steel mounting flange. Any advice would be greatly appreciated.
Thank you for your help
