If you have to change the handrail drive belt look for the service axles that can be pulled out, I believe they have a 8mm screw holding them in. Service axles are usually placed together. Pull 5 steps on top and 5 steps below so you can fit in there to change the belt. Also may wanna clean the handrail drive belt sheaves. Problem with someone splicing is that you don't see the damage to the other parts so you may be replacing the handrail again soon . Clean or replace the turn around cluster rollers as well.
