Anyone know how to remove the stupid little tensioner arms that hold the nylon chain slider blocks ? I busted one putting a slide block on.. It's the arm on the opposite side of the chain from the spring. Not the arm the spring is attached To... Right now it's just sitting there and it looks like it doesn't matter much.. but my fear is if I steer & the chain pulls tight, if that arm spins around and binds into the chain I'm screwed.
