TRIM/TILT
Using the special tool and a torque wrench (1), tighten
the left and right rod guides (2) to the specified torque
as shown.
TOOL:
Pin wrench, 4 mm (3)
TORQUE: 140 N·m (14.3 kgf·m, 103 lbf·ft)
To tighten the rod guide with the pin wrench, 4 mm,
read the torque as follows.
Formula:
Torque wrench (1) reading =[A x B] / [A + C]
A: Torque wrench effective length [m (ft)] (4)
B: Specified torque [N·m (kgf·m, lbf·ft)]
C: Pin wrench effective length [m (ft)] (5)
Example:
Torque wrench reading using a torque wrench with an
effective length of 0.4 m (1.31 ft) and pin wrench with an
effective length of 0.06 m (0.20 ft)
Torque wrench reading =
[0.4 (1.31) x 140 (14.3, 103)] / [0.4 (1.31)] + [0.06
(0.20)]
= 122 [N·m (12.4 kgf·m, 90 lbf·ft)]
A: Torque wrench effective length = 0.4 m (1.31 ft)
B: Specified torque = 140 N·m (14.3 kgf·m, 103 lbf·ft)
C: Pin wrench effective length = 0.06 m (0.20 ft)
I.e. torque wrench reading is 122 N·m (12.4 kgf·m, 90
lbf·ft).
Apply ATF to the manual valve O-rings (1).
Install the manual valve (2) to the pump (3) and tighten
it to the specified torque.
TORQUE: 3.4 N·m (0.35 kgf·m, 2.5 lbf·ft)
Install the internal circlip (4).
Apply ATF to five new O-rings (1) and orifice collar (2).
Install the steel ball (3) into the reservoir valve (4) and
set the pin (5).
Install the reservoir valve into the cylinder.
Install the five O-rings and orifice collar in the cylinder
and install the pump (6) on the cylinder.
Install and tighten the socket bolts A (7) and two socket
bolts B (8) to the specified torque.
TORQUE: 8.3 N·m (0.85 kgf·m, 6.1 lbf·ft)
