DS 250 Drive Chain Tightening Method

Read the manual, and have tried the method of loosening the 2 tensioner bolts, but the caliper support bolt on my sons machine isnt the same as it is in the picture…
any help here would be appreciated, I even sprayed some liquid wrench and let is soak down in the hub area in case it was seized up a bit, but maybe the seize is deeper? Im lost, this should be a simple procedure and its keeping my boy from riding his new toy!
