Description
Hydraulic Flow (cont'dl
Reverse Driving at Constant Speed l2WD)when driving in reverse at a constant speed, the dual pump system functions in two wheel drive mode.The rotation speed of the front and rear wheels is the same, so the speed of the front and rear pumps is also the same,Fluid discharged by the front oil pump is drawn in by the rear oil pump and is circulated through the system. But, becausethe there is a difference in the capacity between the two pumps, fluid flows through check valve E, and then through ori-Iices. This fluid lubricates and cools the clutch assembly and bearings.ls this condition, only a low pressure is built up at the clutch piston. Therefore the clutch does not engage, and the vehicleremains in 2WD (front wheel drive).
Reverse Deceleration l/tWDl
During reverse deceleration, the dual pump system can engage four wheel drive.When decelerating in reverse direction, the speed of the rear wheels may exceed the speed of the front wheels (due toengine braking). In this condition, the rear oil pump draws fluid through check valves B and C. Fluid discharged from therear oil pump then flows through check valve E to the clutch piston. There, pressure is regulated by two orifices.The regulated hydraulic pressure at the clutch piston may force the plates and discs of the clutch together to form a con,nection. The engaged clutch passes driving force from the transfer assembly to the rear wheels, producing 4WD.

Knuckle/Hub Replacement
Note these items during replacement:
. Replace the selt-locking nuts after removal.
. The vehicle should be on the ground before any bolts or nuts connected to rubber mounts or bushings are tightened.
. Torque the castle nuts to the lower torque specifications, then tighten them only far enough to align the slots with each
pin hole. Do not align the nuts by loosening.
o Use only genuine Honda wheel weights for aluminum wheels. Non'genuine wheel weights may corrode and damage
the aluminum wheels.
. Onthealuminum wheels, remove the center cap from the inside of the wheel after removing the wheel.
. Before installing the brake disc, clean the mating surfaces of the front hub and brake disc.
. Before installing the wheel. clean the mating surfaces ofthe brake disc and wheel.
. Wipe off the grease before tightening the nuts at the balljoints.
