CAUTION:
 Secure steering gear assembly with a vise, using copperplates or something similar to prevent it from being damaged.
Do not grip cylinder with a vise.
 Before performing disassembly, clean steering gear assembly
with kerosene. Be careful not to bring any kerosene into con-
tact with the discharge an d return port connectors.
DISASSEMBLY
1. Remove cylinder tubes from gear housing assembly.
2. Remove rear cover cap from gear housing assembly.
3. Measure adjusting screw height from gear housing assembly,
then loosen adjusting screw.
CAUTION:
 Do not turn adjusting screw more than twice.
 Replace steering gear assembly when adjusting screw is
removed or more than twice.
4. Use a rear cover wrench (SST) to remove rear cover from pinion assembly.
5. Remove O-ring with a flat-bladed screwdriver, and pull out rear cover.
6. Remove pinion assembly from gear housing assembly. CAUTION:
In order to protect oil seal from any damage, pull pinion
assembly out straightly.
7. Loosen lock nut of outer socket, and remove outer socket.

c. When installing outer rack oil seal, cover the end of rack with anOHP sheet [70 mm (2.76 in) × 100 mm (3.94 in)]. It will avoid
damaging rack oil seal. Then place oil seal on sheet. Pull rack oil
seal along with OHP sheet until they pass rack end. Then
remove OHP sheet.
d. Install end cover assembly to rack, move it to gear housing assembly.
5. Using a 45 mm (1.77 in) open head (suitable tool), tighten end cover assembly at the specified torque.
CAUTION:
Do not damage rack surface. If it is damaged, it may cause
oil leaks. Replace rack assembly.
6. After tightening end cover assembly, caulk cylinder at one point as shown in the figure using a punch. This will prevent end cover
from getting loose.
7. Install pinion assembly to gear housing assembly. CAUTION:
In order to protect oil seal from any damage, insert pinion
assembly out straightly.
8. Apply recommended fluid to O-ring. Install O-ring to rear cover.
9. Use a rear cover wrench (SST), install rear cover to gear hous- ing assembly.
10. Confirm projection on rear cover cap nearly fit with marking posi- tion on gear housing assembly.
11. Apply recommended thread locking sealant to the thread (2 turns thread), and then screw in the adjusting screw until it
reaches height “H” from gear housing assembly measured
before disassembling.
12. Rotate pinion ten times whole range of rack so that parts get to fit with each other.

4. If tooth contact is improperly adjusted, follow the procedure
below to adjust the pinion height (dimension X).
 If the tooth contact is near the face (face contact), or near the heel (heel contact), thicken pinion height adjusting washers to move
drive pinion closer to drive gear.
Refer to RFD-38, "
Inspection and Adjustment".
 If the tooth contact is near the flank (flank contact), or near the toe
(toe contact), thin pinion height adjusting washers to move drive
pinion farther from drive gear.
Refer to RFD-38, "
Inspection and Adjustment".
Backlash
1. Remove rear cover. Refer to "Differential Assembly".
2. Fit a dial indicator to the drive gear face to measure the back-
lash.
 If the backlash is outside of the specified value, change the thick- ness of side bearing adjusting washer.
CAUTION:

Side gear and Pinion mate
gear  If any cracks or damage on the surface of the tooth is found, replace.
 If any worn or chipped mark on the contact sides of the thrust washer is found, replace.
Side gear thrust washer and
pinion mate thrust washer  If it is chipped (by friction), damaged, or unusually worn, replace.
Oil seal  Whenever disassembled, replace.

1. Make sure all parts are clean and that the bearings are well lubricated.
2. Assemble the pinion gear beari ngs into the differential shim
selector tool.
 Pinion front bearing; make sure the J-34309-3 pinion front
bearing seat is secured tightly against the J-34309-2 gauge
anvil. Then turn the pinion front bearing pilot, J-34309-5, to
secure the bearing in its proper position.
 Pinion rear bearing; the pinion rear bearing pilot, J-34309-8,
is used to center the pinion rear bearing only. The pinion rear
bearing locking seat, J-34309-4, is used to lock the bearing to
the assembly.
 Installation of J-34309-9 and J-34309-16; place a suitable
2.5 mm (0.098 in) thick plain washer between J-34309-9 and
J-34309-16. Both surfaces of J-34309-9 and J-34309-16 must
be parallel with a clearance of 2.5 mm (0.098 in).
3. Install the pinion rear bearing inner race into gear carrier. Then place the pinion preload shim selector tool, J-34309-1, gauge
screw assembly.
4. Assemble the pinion front bearing inner race and the J-34309-2 gauge anvil. Assemble them together with the J-34309-1 gauge
screw in gear carrier. Make sure that the pinion height gauge
plate, J-34309-16, will turn a full 360 degrees. Tighten the two
sections together by hand.
5. Turn the assembly several times to seat the bearings. Tool number : — (J-34309)

6. Measure the turning torque at the end of the J-34309-2 gaugeanvil using preload gauge.
7. Place the J-34309-11 “R200A” pinion height adapter onto the gauge plate and tighten it by hand.
CAUTION:
Make sure all machined surfaces are clean.
8. Position the side bearing discs, J-25269-4, and arbor firmly into the side bearing bores. Install the bearing caps and tighten bear-
ing cap mounting bolts to the specified torque. Refer to "COM-
PONENTS".
9. Select the correct standard pinion height adjusting washer thick- ness. Select by using a standard gauge of 3 mm (0.12 in) and
your J-34309-101 feeler gauge. Measure the distance between
the J-34309-11 pinion height adapter including the standard
gauge and the arbor.
10. Write down exact measurement (the value of feeler gauge). Tool number : ST3127S000 (J-25765- A)

11. Correct the pinion height washer size by referring to the “pinion head number”.
There are two numbers painted on the drive pinion. The first
one refers to the drive pinion and drive gear as a matched
set. This number should be the same as the number on the
drive gear. The second number is the “pinion head height
number”. It refers to the ideal pinion height from standard
for quietest operation. Use th e following chart to determine
the correct pinion height washer.
12. Select the correct pinion height adjusting washer. Refer to RFD-38, "
Inspection and Adjustment".
13. Remove the J-34309 differential shim selector tool from the final drive housing. Then disassemble to retrieve the pinion bearings.
