BW4412 Transfer Case for Ford 2006-2010 Explorer/Mountaineer 4.0L, w/o Shift Motor

Description

Providing continuous full-time all-wheel drive, BorgWarner BW4412 AWD Marine Gearbox units deliver mechanical power transfer with a 1.00:1 ratio for 2006 to 2010 Ford Explorer and Mercury Mountaineer 4.0L V6 platforms without shift motors. Rated for 245 continuous horsepower at a 5,400 RPM ceiling, this unit directs balanced power across front and rear drive axles during vessel staging on harbor ramps.

Constructed with an extra-thick die-cast magnesium casing split horizontally, this unit minimizes bore distortion under severe tractive loads. A central differential gearset works with a high-strength Morse drive chain to modulate torque distribution between front and rear driveshafts without electronic actuators. High-capacity needle and tapered roller bearings absorb combined radial and axial thrust. The 1.2-quart lubricant capacity flows through internal channels, keeping roller bearings lubricated under continuous duty cycles.

Key Features of BorgWarner BW4412 AWD

Fleet maintenance directors buy BorgWarner BW4412 AWD marine gearbox units to maintain dependable four-wheel drive pulling power in modern shipyard transport trucks. This front differential carrier balances torque output across independent front suspension half-shafts during heavy marine vessel maneuvers.

• Full-time all-wheel drive configuration eliminates shift motor failures on wet harbor ramps
• Internal center differential divides torque smoothly between front and rear drive axles
• Input splines interface straight with Ford 4.0L V6 five-speed automatic transmissions
• BorgWarner BW4412 AWD internal components maintain gear mesh alignment under shock torque
• High-capacity Morse drive chain transfers front driving torque without elongation
• Internal oil pump maintains continuous lubrication across mainshaft roller bearings
• Rear companion flange connects straight to independent rear suspension driveshafts
• Front companion flange connects straight to constant-velocity front driveshafts

Full Time AWD Mechanics

Built for severe commercial service ratings, this transfer case manages 1,580 lb-ft of continuous input torque at 2,400 driveline RPM. The direct 1.00:1 ratio delivers responsive torque distribution while maintaining transfer case sump operating temperatures between 150°F and 175°F. Heat transfer across the magnesium housing dissipates up to 2.1 kW during continuous all-wheel drive ramp work. Advanced tooth contact patterns distribute gear stress uniform across tooth faces, preventing tooth shearing under full engine acceleration.

Companion Flange Mating Limits

The companion pinion flange accommodates constant-velocity driveshafts with a precision-drilled four-bolt pattern. Dual opposing tapered roller bearings resist 3,000 pounds of continuous axial pinion thrust. Dial indicator alignment inspection must show less than 0.0025 inches radial runout relative to the front driveshaft centerline.

Constant Traction Service Regimen

Check automatic transmission fluid condition through the casing threaded fill port before operating support vehicles on steep boat ramps. As an explicit negative filter, this transfer case unit is not engineered for direct propeller shaft connection or inboard commercial vessel propulsion systems.

• Inspect transfer case housing fluid levels and breather valve freedom each shift before ramp transit
• Examine front output seal lip contact areas and driveshaft CV boots every 250 hours of operation
• Replace synthetic Mercon fluid and clean magnetic drain plug every 12 months of service

Commercial Limited Warranty Manifest

This transfer case includes a 1-Year commercial limited warranty against material and craftsmanship defects. Crated shipment contents feature the assembled transfer case unit, front companion yoke, rear output flange, vent tube fitting, and comprehensive installation documentation.
