The Linear 227653 HCI Drive Sprocket is a genuine OEM replacement component designed for Linear HCI gate operators. Positioned in the drivetrain, this sprocket engages the operator’s chain to transfer motor power to the output, helping restore smooth, reliable travel and consistent torque delivery. It is engineered for a direct fit in HCI systems that specify part number 227653 in their service or parts documentation, making it an ideal replacement part for repair, preventative maintenance, or performance restoration in commercial and industrial automatic gate applications.
Use this part when you notice symptoms such as chain slip, irregular movement, or tooth wear inside the operator. For installation, disconnect power and follow lockout/tagout procedures, remove the chain guard, relieve chain tension, align the sprockets, secure the new drive sprocket as specified in the Linear HCI service manual, and retension the chain before testing. No programming is typically required unless travel limits or control settings are adjusted during service. Always verify compatibility with your exact HCI model using the operator’s parts list or by consulting Linear technical documentation.
