Standard Ignition FD-112 Distributor Rotor

Distributor Rotor for Ford Pinto and Mercury Capri

Standard Ignition FD-112 is a distributor rotor built for direct-fit service in select Ford and Mercury applications. It is engineered with a dielectric-strength alkyd body to help resist dirt buildup and reduce carbon tracking, while solid brass segments support strong conductivity for consistent spark delivery.

Compatible With 1971-1973 Ford Pinto and 1971-1972 Mercury Capri applications, this rotor is a practical replacement for ignition service on classic vehicles that need reliable distributor performance. The FD-112 part number is also useful when matching an existing service reference during ignition repair.

Key Features

• Distributor rotor for ignition system service
• Dielectric-strength alkyd construction helps resist dirt adhesion
• Helps reduce carbon tracking for longer service life
• Solid brass segments support conductivity and spark transfer
• Shaft retention clips used where required for fit and performance
• Standard Ignition FD-112 replacement part number

Detailed Description

Standard Ignition FD-112 is a distributor rotor intended for classic Ford Pinto and Mercury Capri ignition systems. The rotor’s alkyd material helps maintain electrical isolation inside the distributor, while the brass contact segments are selected to carry voltage efficiently from the distributor to the plugs. This combination supports stable ignition performance in older vehicles where rotor wear, tracking, or poor conductivity can affect drivability. If you are sourcing a Ford Pinto distributor rotor or a Mercury Capri ignition rotor, FD-112 provides a direct replacement reference for these applications.

This part cross-references 4R1076 and 6-430 for the same application.

What It Helps Address

• Misfire caused by worn rotor contacts
• Carbon tracking inside the distributor cap and rotor area
• Weak spark transfer from the distributor to the plugs
• Ignition performance loss from rotor material breakdown
• Fitment issues when replacing an existing FD-112 reference

Installation Notes and Tips

Inspect the distributor cap, rotor tip, and related ignition components before installation. Clean the distributor interior to remove dirt or carbon residue, and confirm the rotor seats correctly on the shaft. For best results, replace worn cap and rotor components together when service wear is present. Verify application by year and model before ordering: Fits 1971-1973 Ford Pinto and Fits 1971-1972 Mercury Capri.

Quality Assurance

Standard Ignition uses materials and design details aimed at improving electrical performance and service life, including brass segments and retention features where required. FD-112 is built as a replacement ignition component for the listed Ford and Mercury applications.
