Changing the timing belt-cylinder  

 

 

Fig. 24 

1.

 

The timing belt is lowered on solid 
surfaces and the pressure is taken 
off the timing belt-cylinder. 

2.

 

The hoses are installed on the cylin-
der. 

3.

 

The cylinder is supported. 

4.

 

Cotter pins and nails are removed, 
and then the cylinder is free. 

5.

 

The  new  or  repaired  cylinder  is  in-
stalled.  Remember  to  secure  the 
nail in the nail stop and secure the 
nails with cotter pins. 

6.

 

The hoses are installed. After instal-
lation, ensure that there is no risk of 
tearing or clamping the hoses. 

 

 

 

After installation, activate the cylinders again. The cylinders are activated both 
ways and are fully sealed in both outer positions. This must be done in order to ven-
tilate the system with the cylinder.  

 

 

 

There must never be persons within the operating radius.
