Toyota 19102-45150 Distributor Rotor Sub-Assembly

Removal steps 1. Park on level ground, set the parking brake, chock wheels, wear safety glasses, and let the engine cool. 2. Disconnect the negative battery cable to prevent accidental ignition sparks. 3. Remove or move aside any covers or components that block access to the distributor cap; access methods vary by vehicle. 4. Photograph or clearly label each spark plug wire or ignition lead at the distributor cap to preserve firing order. 5. Carefully remove spark plug wires by pulling the boots, not the wires, and set them aside in order. 6. Remove the distributor cap fasteners and lift the cap straight off; some caps have internal leads-handle gently. 7. Identify the rotor retention method (press-fit, clip, or screw); remove the retaining clip or screw if present, or pull the rotor straight up if it is a friction fit. 8. Lift the rotor from the distributor shaft, noting its orientation for correct reinstallation. Installation steps 1. Confirm the replacement rotor matches the original in shape and orientation before installing. 2. Clean the distributor shaft and cap seating area of debris and corrosion with a lint-free cloth. 3. Install the new rotor onto the distributor shaft in the same orientation as removed; push it straight on or reinstall the retaining fastener if one is used-do not use excessive force. 4. Reposition the distributor cap and secure its fasteners, ensuring it seats evenly and any indexing features engage. 5. Reattach spark plug wires to the correct terminals using your labels or photos, seating each boot fully on its terminal. 6. Reconnect the negative battery cable. 7. Start the engine and observe for normal idle and absence of misfires; if running poorly, recheck rotor seating and wire order. 8. After a short test run, inspect for oil or moisture intrusion around the distributor and confirm all fasteners remain secure. Repair tip 1. It is common practice to replace the distributor cap at the same time as the rotor for reliable performance and longer service life.
