I have a Kymron lots of issues with bolts. The Chinese are pitiful with QC . I have found thur research that your excavator, Kymron , and a number of others are made by a Company in China by Hightop. All having poor workman ship in design & assembly / QC. I should have bought a Kubota !
I had the exact thing happened to mine. Started leaking fluid out of the bottom after about 5 hours of use. Initially found those bolts to be very loose and tighten them down. Must have tightened on top of the o-ring because when I pulled it out it was also chewed up just like yours. Found a similar size replacement one at Lowe's in one of the multi-packs.
Do you have the AGT H12? There could be some pressure against the gear, try moving the machine some when you pull the motor. I saw another video where somebody had to pull the gear off before the motor would come out. Good luck & I hope you find an easy solution.

Do you have to relieve hydraulic pressure for this ? And what about bleeding the system, do you have to ?
There should not be pressure on the hydraulic lines & I did not bleed the system... no problems
Hello David, same problème here, which type of ring you put please, 138 mm?
Hey David, I have the same problem with my swivel motor. I removed the 4 bolts and 2 hoses, but the motor would not come off. Any suggestions?
