rack. Otherwise, oil leaks may result.
11. Pull rack assembly with rack oil seal out of gear housing assem- bly.
CAUTION:
Be careful not to damage cylinder. If it is damaged, replace
gear housing assembly. Otherw ise, oil leaks may result.
12. Heat rack Teflon ring to approximately. 40 °C (104 °F) with a
dryer, then remove it and O-ring from rack.
CAUTION:
Be careful not to damage rack. If it is damaged, change to a
new one to avoid oil leaks.
13. Use a taped 29 mm (1.14 in) socket and an extension bar. Remove rack oil seal from gear housing assembly.

2. Heat rack Teflon ring to approximately 40 °C (104 °F) with a
dryer. Assemble it to mounting groove of rack.
3. To fit rack Teflon ring on rack, use rack Teflon ring installation tool (SST) from tooth side. Comp ress rim of ring with the tool.
4. Apply recommended grease to rack oil seal. Insert rack oil seal, then insert rack assembly to gear housing assembly.
CAUTION:
 When inserting rack assembly, do not damage retainersliding part. If it is dama ged, replace gear housing assem-
bly.
 When inserting rack assembly, do not damage cylinder
inner wall. If it is damaged, it may cause oil leaks. Replace
gear housing assembly.
 Attach rack oil seal. Both in ner lip and outer lip should
face each other.
a. To avoid damaging inner rack oil seal, wrap an OHP sheet [approximately. 70 mm (2.76 in) × 100 mm (3.94 in) around rack
tooth. Place oil seal on sheet. Then, pull oil seal along with OHP
sheet until they pass the toothed se ction of rack, then remove it.
b. Insert rack oil seal (inner) to piston (rack Teflon ring) position and push retainer to adjust screw side with fingers lightly, and
then make rack move in gear housing assembly, install rack oil
seal (inner) to fit with gear housing assembly.

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.
