My sidewinder doesn't have the inner bolts anymore, none of them do. They use a large washer on the head of the bolt with a spacer and either .5mm washers or 1mm to set the belt height. Therefore, anytime one of the inner machinery washers is remove or added the outside stack must be re-adjusted. Yours is like this also more or less, I think you will figure it out, just keep studying it.
