Temperature-Responsive Fan Engagement

The fan clutch allows controlled slip when extra airflow is not needed, then transmits more torque as temperature rises. This reduces the drawbacks of a permanently rigid fan drive.

Inspect for cracked blades, loose fasteners, shaft play and contact marks before replacing the hub. A damaged fan can overload a new clutch and create a safety risk.

Buyer Matching Guide

Send 4406277, FORD Transit engine details and original-part photographs when interchangeability is uncertain. Front, rear and side views are especially useful.

Confirm the OE number and usable cross-references.

Match vehicle model, engine, chassis and production period.

Check drive-side thread or flange and rotation direction.

Measure hub height, pilot diameter and fan bolt circle.

Verify blade alignment and clearance inside the shroud.

Commercial and Heavy-Duty Cooling Notes

FORD Transit applications may spend long periods idling, towing or working at low road speed. Confirm radiator cleanliness, shroud sealing, belt condition and fan-blade integrity so the replacement clutch operates inside a complete and correctly maintained cooling-airflow system.

Installation and Cooling-System Checks

Installation should be completed by a qualified technician. Follow the specified thread direction and torque procedure, inspect the fan and water-pump bearing, replace damaged hardware, and confirm that the blade rotates freely without contacting the radiator or shroud. Test the vehicle under the appropriate warm operating conditions after assembly.

Packing and QC Notes

For repeat orders, sample records can compare hub dimensions, hole positions, surface finish and carton labeling with the approved reference.

Ordering Specification Notes

To reduce selection risk, treat 4406277 and FD01012-006 as the start of the FORD Transit specification. Add thread or flange details, pilot diameter, bolt pattern, hub offset and shroud clearance. The resulting checklist supports quotation, approval, receiving and installation review.

Wholesale and Procurement Information

Distributors sourcing 4406277 should use FD01012-006 in purchase orders and warehouse records. Include barcode, carton and shipment-document needs at quotation stage.

Frequently Asked Questions

Can I select 4406277 from the product photo alone?

No. Similar housings can have different threads, offsets, rotation or fan patterns, so physical and catalogue checks are required.

What other faults can resemble a weak fan clutch?

Radiator blockage, low coolant, thermostat faults, belt slip, damaged shrouds and water-pump problems can create similar symptoms.

May old mounting hardware be reused?

Only if the service information permits it and every fastener is undamaged. Follow the specified direction and torque.

Can export packing be adjusted for FD01012-006?

Carton protection, neutral labels and customer branding can be reviewed according to volume and destination.

How do I request a quote for FORD Transit?

Send OE 4406277, SKU FD01012-006, quantity, delivery country and any fitment or inspection evidence.
