Specifications

Controls and Operation

Manual operation via window crank handle. No electrical components required.

Operation: Insert crank handle and turn clockwise to raise window, counterclockwise to lower window. Smooth, consistent force should be applied for optimal operation.

Maintenance: Regular lubrication of gear mechanism and sliding surfaces. Inspection: Check for wear on gear teeth and mounting points every 6 months. Adjustment: Minor alignment adjustments possible via mounting bolt slots. Safety: Manual operation provides reliable function without electrical dependency.

Connecting Components

Integration with existing door assembly including window glass, door frame, and interior panel.

  1. Window glass attachment: Secure window to regulator mechanism with proper bolts.
  2. Door frame mounting: Align regulator with factory mounting points in door frame.
  3. Crank mechanism: Connect manual crank handle to regulator gear assembly.
  4. Weather sealing: Ensure proper alignment with window seals and channels.

Tip: Test window operation at each connection point before final assembly.

Maintenance Procedures

Regular maintenance ensures long-term reliability and smooth operation.

  1. Lubrication: Apply white lithium grease to gear mechanism every 6 months.
  2. Inspection: Check for wear on gear teeth and mounting hardware annually.
  3. Cleaning: Remove debris from window tracks and mechanism regularly.
  4. Alignment: Verify window tracks properly in channels during seasonal changes.
  5. Tightening: Check mounting bolt torque every 12 months.

WARNING! Use only recommended lubricants; improper products may damage mechanism.

Safety Features

Manual operation eliminates electrical failure risks. Built-in safety stops prevent over-travel. Durable construction resists impact and wear.
