Chain tightening link
Tip; I might suggest that when you get the chain set right, if you have a drum brake on the rear, that when you tighten the axle nut you hold the brake pedal down. This expands the pads out to press evenly on the drum to center the drum around the pads. This will help the brake work better, both pads will hit the drum at the same time.
