Replacing tilting cylinder seals 

Fig. 27 

 

 
1.

 

Empty the oil from the cylinder by carefully moving the cylinder back and forth.  

2.

 

Move the piston to the middle position. Unscrew the gland (pos. 3) from the cyl-
inder casing (pos. 1). (A special tool is needed to remove the gland). If the gland 
is stuck, it may help to warm up the very front of the socket. When the gland has 
been unscrewed, pull the piston towards the gland. Pull the piston rod complete-
ly out of the cylinder casing (pos. 1).  

3.

 

Remove the self-locking nut (pos. 10) holding the sleeve (pos. 4). 

4.

 

Pull the sleeve (pos. 4) off the piston rod (pos. 2). 

5.

 

Pull the gland (pos. 3) off the piston rod (pos. 2). 

6.

 

Remove the seals from the gland and the sleeve (pos. 5+6+7+8+9). 

7.

 

Clean all parts thoroughly. Check for filings, shavings, burrs, and make sure that 
there is no rust around the scraper ring (pos. 5) in the gland. If rust is found, it 
must be removed.  

 

Assembly 

1.

 

Assemble the new seals (pos. 5+6+7+8+9) into the gland and the sleeve.  

2.

 

Lubricate the screw threads on the gland (pos. 3) and the cylinder casing (pos. 
1) with oil.  

3.

 

Mount the gland (pos. 3) onto the piston rod.  

4.

 

Mount the sleeve (pos. 4) and screw on the self-locking nut

 with Loctite

. Make 

sure that the screw threads are completely clean and free from oil or other im-
purities before using Loctite.

 Do not refill the oil for the first 12 hours after the 

application of Loctite.

 

5.

 

Lubricate  the  outermost  seal  of  the  sleeve  that  has  contact  with  the  cylinder 
casing and the inside of the cylinder casing, then guide the piston rod into the 
middle position of the casing.  

6.

 

Screw the gland onto the casing and tighten. 

7.

 

To mount the cylin

der, (see ”Changing wing fold cylinders”).
