Insert the piston rod into the inner tube.
Hold the inner tube bottom by a vise.
Using rod guide case wrench [A], tighten the piston rod
guide case to the inner tube.
Special Tool - Rod Guide Case Wrench, 33 mm: 57001
Torque - Piston Rod Guide Case: 90 N·m (9.2 kgf·m, 66 ft·lb)
The tightening torque of the piston rod guide case is
specified to 90 N·m (9.2 kgf·m, 66 ft·lb), however in use
of the rod guide case wrench (special tool: 57001-1744)
[A] you reduce the torque to about 90% of the specified
value [81 N·m (8.3 kgf·m, 60 ft·lb)] due to the offset [B]
of the wrench square hole.
This torque value [81 N·m (8.3 kgf·m, 60 ft·lb)] is appli-
cable when you use a wrench whose length [C] gives
leverage of approximately 450 mm (17.7 in.) between
the grip point [D] to the center of the coupling square.
To obtain the correct tightening torque with your torque
wrench, you need to calculate as follows.
a × b ÷ (b + c) = d
[a] Specified torque
[b] Length from center of square hole to grip point
[c] Offset = 50 mm
[d] Tightening torque
For an example:
90 N·m × 450 ÷ (450 + 50) = 81 N·m
A socket of piston rod guide case is shallow (4 mm)
and therefore be sure to check that the wrench
(Special Tool: 57001-1744) is securely seated on
the piston rod guide case.
When tightening the piston rod guide case. If the
wrench is not securely seated on it, the piston rod
guide case may break.
Install the piston rod nut [A] until it is bottomed.
