Well according to the parts diagram below the spring you have connecting plates 7 & 8 together is in the wrong place
It should go from the anchor bolt on plate 8 where it is right now to the same bolt that spring 35 goes to which looks like it is part of the pulley guard part 2
Note the free end of both have the letter E at their ends
This will swing plate 8 substantially further to the right which should give you clean access to the anchor bolt on plate 7 for the currently orphaned tension spring
