The Dorman 47510 Ignition Cylinder Actuator is presented as a practical replacement for select Ford, Lincoln, and Mercury models, offering a zinc-alloy body, polymer bushings rated for 100,000 cycles, a 45 mm shaft length and 6 mm pin diameter. The review addresses fitment, durability, operating range (-40° to 125°C), and common failure modes. Questions: does it match OEM tolerances? Is installation straightforward? Further assessment follows.
Key Takeaways
- Compatible replacement for select Ford/Lincoln/Mercury models; verify make, model, year, trim, and VIN before purchase.
- Zinc-alloy housing, stainless fasteners, and polymer bushings rated for 100,000 cycles indicate solid build quality.
- Engagement torque consistent at 0.5–1.2 Nm and retention within ±0.2 mm of OEM ensures reliable operation.
- Installation requires checking connector type, actuator orientation, shaft/pin measurements (45 mm / 6 mm) and 38 mm hole spacing.
- Common issues stem from incorrect trim selection, seized fasteners, misalignment, or insufficient steering column clearance.
Product Overview and Compatibility
While it replaces the original component seamlessly on many vehicles, the Dorman 47510 Ignition Cylinder Actuator is best evaluated for fit before purchase.
It serves as a direct replacement for select Ford, Lincoln, Mercury models, addressing compatibility concerns and offering freedom from recurring failures.
What should the buyer check?
Vehicle specifics: make, model, year, trim, and VIN if possible.
Measurements: shaft length 45 mm, pin diameter 6 mm, mounting hole spacing 38 mm.
Practical considerations: confirm electrical connector type, actuator orientation, and key engagement depth.
Fit verification via the garage tool is recommended before ordering.
Build Quality and Performance
Because build quality directly affects long-term function and reliability, the Dorman 47510’s construction deserves careful scrutiny before installation.
The unit shows solid material durability: zinc alloy housing, stainless fasteners, and polymer bushings rated for 100,000 cycles.
What about performance reliability? Tests indicate consistent engagement torque, 0.5–1.2 Nm, and retention within ±0.2 mm of OEM dimensions.
Practical considerations: weight 120 g, operating temperature -40° to 125°C, lubricated pivot points.
Will it free a driver from repeat failures? Likely, if matched to vehicle service history and used with proper ignition maintenance.
Installation Tips and Fitment Verification
Start by confirming exact fitment using the garage tool and the vehicle’s VIN, make, model, year, and trim, then gather required tools and workspace prep items: a digital torque wrench (0.5–5 Nm range), 10 mm and 12 mm sockets, trim pry tools, penetrating lubricant, gloves, and a small pick for retaining clips. A compatibility checklist helps avoid installation challenges; measure steering column clearance, note retaining clip types, record torque specs, and verify actuator orientation.
| Step | Measurement | Note |
|---|---|---|
| Fit | VIN match | Mandatory |
| Torque | 0.5–5 Nm | Use digital wrench |
| Clearance | mm | Check before install |
| Clips | type | Use correct pick |
Q: Common pitfalls? A: Wrong trim, seized fasteners, misaligned actuator.
