(Continued from the previous section)
1
Apply the methanol or deionized water to the mating surface
between the cap seal [31] and U-packing [33] to improve slip.
2
Mount the backup ring [23] to the retainer [14].
3
Mount the retainer [14] to the piston rod [13].
- Make sure to mount the retainer straight in to prevent the piston
rod [13] from being scratched.
4
Mount the cap seal [31] to the piston [12].
5
Mount the piston [12] to the piston rod [13].
6
Mount the piston collar [10] to the piston rod [13].
7
Mount the piston lock nut [9] to the piston rod [13].
- Since the employed lock nut is a double nut, tighten the two
nuts with two wrenches.
- Tighten the nut horizontally and uniformly.
- In mounting the piston lock nut [9], be careful to keep the
piston rod [13] from contact with the retainer [14], so that they
do not receive flaws.
8
Mount the lock nut [2].
9
Mount the cylinder [8].
- Do not touch the cylinder inner surface directly by hand.
