I would say if the rubber is dry or cracking it need repaired or replaced

Or maybe install it with #1 cylinder at tdc and see how the scribed line matches up with the timing tab on the engine if this is the first rebuild a d stock balancer the tabes should match correct me i i am wrong i do believe there are a couple different tabs?
