Installation & Maintenance Tips
1. Installation & Shipping Guidance: Direct aftermarket replacement. Installation position: Undercarriage, outer flanges match rubber track guiding system, inner flange enhances stability. Factory recommendation: Replace with other vulnerable undercarriage parts and rubber track. Shipping: Heavy weight, must ship via freight truck on pallet—do not select FedEx Ground.
