Description
Rear Differential
Outline
The Real-time 4WD-Dual Pump System model has a hydraulic clutch and a differential mechanism in the rear differential
assembly. Under normal conditions, the vehicle is driven by the front wheels. However, depending on to the driving force
of the front wheels and the road conditions. the system instantly transmits appropriate driving force to the rear wheels
without requiring the driver to switch between 2WD (tront wheel drive) and 4WD (four wheel drive). The switching mecha-
nism between 2WD and 4WD is integrated into the rear differential assembly to make the system light and compact.
ln addition, the dual-pump system switches off the rear-wheel-drive force when braking in a forward gear. This allows the
braking system to work properly on models equipped with an Anti-lock Braking System (ABS).
Construction
The rear differential assembly consists of the torque control differential case assembly and the rear differential carrier
assembly. The torque control differential case assembly consists of the differential clutch assembly, the companion
flange, and the oil pump body assembly. The rear differential carrier assembly consists of the differential mechanism. The
differential drive and driven gears are hypoid gears.
The oil pump body assembly consists of the front oil pump, the rear oil pump, the hydraulic control mechanism, and the
clutch piston. The clutch piston has a disc spring that constantly provides the differential clutch assembly with a preset
torque to Drevent abnormal sound.
The clutch guide in the differential clutch assembly is connected to the propeller shaft via the companion flange, and it
receives the driving force lrom the transfer assembly. The clutch guide rotates the clutch plate and the front oil pump in
the oil pump body.
The clutch hub in the differential clutch assembly has a clutch disc that is splined with the hypoid drive pinion gear. The
hypoid drive gear drives the rear oil pump.
The front and rear oil pumps are trochoidal pumps. The rear oil pump capacity is 2.5 percent larger that the front oil pump
to handle the rotation difference between the front and rear wheels caused by worn front tires and tight corner braking.
The oil pumps are designed so the fluid intake works as a fluid discharge when the oil pumps rotate in reverse. Genuine
Honda CVT fluid is used instead of differential fluid.
Operation
When there is a difference in rotation speed between the front wheels (clutch guide) and rear wheels (hypoid driven gear),
hydraulic pressure from the front and rear oil pumps engages the differential clutch, and drive force from the transler
assembly is applied to the rear wheels.
The hydraulic pressure control mechanism in the oil pump body selects 4WD mode when the vehicle is started abruptly,
or when accelerating in a forward or reverse gear (causing rotation difference between the front and rear wheels). or
when braking in reverse gear {when decelerating). lt switches to 2WD mode when the vehicle is driven at a constant speed
in forwar! or reverse gear (when there is no rotation difference between the front and rear wheels), or when braking in a
fo rwa rd gear (when decelerating).
To protect the system, the differential clutch assembly is lubricated by hydraulic pressure generated by the oil pumps in
both 4WD and 2WD modes. Also, the thermal switch relieves the hydraulic pressure on the clutch piston and cancels 4WD
mode if the temDerature of the differential fluid rises above normal.

lnstallation
1. Install the outboard ioint into the knuckle.
KNUCKLE
OUTBOARD JOINT
Apply 0.5 - 1.0 g (0,02 - 0.04 oz) of specified grease to
the whole sDlined surface of the intermediate shaft.
After applying grease. remove the grease from the
splined grooves at intervals of 2 - 3 splines and from
the set ring groove so air can bleed from the inboard
ioint.
SET RINGReplace.
SET RING
Install a new set ring onto the driveshaft or interme-
diate shaft groove.
4. Clean the areas where the driveshaft contacts the
differential thoroughly with solvent or carburetor
cleaner, and dry with compressed air. Insert the
inboard end of the driveshaft into the differential or
intermediate shaft until the set ring locks in the
groove.
INBOARD JOINT
INBOARD JOINT
lnstall the knuckle on the lower arm. Be careful not to
damage the ball joint boot. Wipe off the grease before
tightening the nut at the ball joint. Torque the castle
nut to the lower torque specification. then tighten it
only far enough to align the slot with the pin hole. Do
not align the nut by loosening. lnstall a new cotter pin.

1. Clean the areas where the intermediate shaft con-
tacts the transmission (differential) thoroughly with
solvent or carburetor cleaner, and dry with com-
pressed air. Insen the intermediate shaft assembly
into the differential. Hold the intermediate shaft hor-
izontal to prevent damage to the differential oil seal.
