INSTALL OIL SEAL
| *1 | O-ring |
| *2 | Ring |
| *3 | Oil Seal |
| *4 | Snap Ring |
| *5 | Spacer |
Coat new the spacer and O-ring, ring with power steering fluid.
Install the O-ring, spacer and ring.
Using a snap ring pliers, install a new snap ring.
Coat new oil seal with power steering fluid.
Install oil seal to the gear housing.
INSTALL O-RING
Coat a power piston, dust seal and a new O-ring with power steering fluid.
Snug the dust seal down with the piston ring compressor for 5 - 7 minutes.
INSTALL VALVE HOUSING ASSEMBLY
Using a plastic hammer and a sliding handle, lightly tap in 2 new union seat.
Note
Before installing the union seat, remove dust sticking to the control valve housing.
Mount the gear housing on SST and clamp SST in a vise.
Using SST, install the power piston assembly unit holding the power piston by your finger.
Install the 4 bolts.
INSPECT PRELOAD
Using SST, check the power piston rotating torque.
| Rotating torque |
|---|
| 0.29 - 0.54 N*m (3.0 - 5.51 kgf*cm, 2.58 - 4.75 in.*lbf) |
If the rotating torque is not within the limits or the difference between clockwise and counterclockwise rotating torque is over 0.54 N*m (5.51 kgf*cm, 4.75 in.*lbf), replace the power steering gear assembly.
INSTALL SIDE COVER
Set the power piston at the center of the shaft.
To prevent oil seal and O-ring from damage, wind vinyl tape on the serrated part of the sector shaft.
Install and push the sector shaft into the gear housing so that the center teeth mesh together.
Install the sector shaft side cover with the 4 bolts.
INSPECT TOTAL PRELOAD
Using SST, turn the power piston shaft to full lock in both direction and determine the exact center.
| *a | Matchmark |
Align the matchmarks on the power piston shaft and end cover of the power piston assembly to show neutral position.
Install SST with a torque wrench in the power piston shaft.
Using a screw driver, turn the sector shaft adjusting screw until the preload is within specification.
| Preload (turning) |
|---|
| 0.49 - 0.93 N*m (5.0 - 9.5 kgf*cm, 4.3 - 8.2 in.*lbf) |
Using a screw driver, hold the adjusting screw and torque the lock nut.
Recheck the total preload.
| Preload (turning) |
|---|
| 0.49 - 0.93 N*m (5.0 - 9.5 kgf*cm, 4.3 - 8.2 in.*lbf) |
