With the fabrication of some special tools, I was able to finish the job.
Borrowed a 600 ft-lb torque wrench from work:
Mounted the swing cylinder in the pivot post and ran the bolt in with my impact gun after applying #271 loctite to the bolt:
Used my home-made torque multiplier to get to the specified 1100 ft-lb for the piston bolt:
Partially threaded on the cylinder tube, and endcap, and installed the home-made spanner wrench to the cap via a 9/16-18 bolt into the rear port:
Moved the swing cylinder to the trunion mount, applied loctite to both sets of threads, and ran the housing together with my impact gun:
Reassembled everything, tested the swing back and forth for a while, no leaks.
So I'm no longer afraid to rebuild HYD cylinders.
