Select chain and sprocket must pay attention to whether the two match, and to ensure the concentricity of the sprocket and tire (sprocket Block), otherwise it will lead to conveyor chain a bear in a loose but its early wear and tear.
Installation, put the sprocket on the worn sprocket seat, mounted on the sprocket screws to put the locking gasket, do not screw too tight, the chain together with the tires mounted on the car and then loaded, and slightly tighten the chain slowly turn the rear wheel to observe the tightness of the chain. If the chain loosening and tightening, indicating that the sprocket and tire (sprocket Block) heart.
Adjustment, turn the rear wheel to the chain tight at the wooden hammer or rubber hammer to gently tap sprocket forward, so that the chain relaxation (non-iron hammer, otherwise it will damage the chain sprocket). Turn the rear wheels observe the chain is a loosening and tightening, broadly stable in the repeated several times until the conveyor chain, tighten the sprocket screws and locking gaskets, check the tightness of the chain. In this way, the tires and sprocket basic concentric, the car running will be very easy.
