Procedures:

Disassembling/assembling the outer cylinder
Disassembling the left-hand outer cylinder
– Pull the piston rod approx. 20 cm out of the cylinder pipe.
– Using protective jaws, clamp the piston rod in the vice.
– Unscrew the hydraulic adapter. The hydraulic adapter is secured with Loctite, so it may be necessary to gently heat the thread.
The next steps of the disassembly process are the same for both of the outer cylinders.

Disassembling the left-hand and right-hand outer cylinder
– Using protective jaws, clamp the cylinder pipe loosely in the vice.
– Unscrew the cylinder head using a hook spanner. The cylinder head is secured with Loctite, so it may be necessary to gently heat the thread.
– Remove the cylinder head from the piston rod.
– Remove the set of seals.

Assembling the outer cylinder
– Clean the cylinder head and check for signs of wear and damage.
– Insert a new set of seals into the cylinder head.
– Lightly coat the seals with hydraulic oil.

– Check the piston rod and the chamfer for damage.
– Clean and degrease the thread on the cylinder pipe and cylinder head.
– Secure the thread by spreading three drops of Loctite 243 over the entire thread.

– Attach the cylinder head and screw it on as far as it will go using a hook spanner. Secure the cylinder head by knocking the hook spanner with two blows of the hammer.
