TAG000220 - IRD Unit – 6-Cyl
The IRD takes the gearbox output and splits it two ways. Drive to the front wheels passes through the differential carried inside the unit, which feeds the two front driveshafts and allows them to turn at different speeds when cornering. Drive to the rear passes through the hypoid gear set to the rear output pinion, and from there via the propshaft and viscous coupling unit to the rear differential.
Internally the unit comprises the main casing and right-hand housing, the primary and intermediate shafts, the laygear and hypoid gear set, the differential unit, and the rear output pinion with its housing.
The IRD and the rear differential must run matched ratios. A mismatch - most often introduced by mixed or unevenly worn tyres, or by an incorrectly specified replacement unit - places the viscous coupling under permanent load and will destroy the coupling, the IRD and ultimately the rear differential.
Supplied as a new unit rather than a remanufactured exchange assembly.
