5. DISASSEMBLY AND ASSEMBLY

5.1 DISASSEMBLY AND ASSEMBLY, LIFTING CYLINDER

A defective lifting cylinder is often caused by 
leaking oil sealing rings or a damaged piston rod. 
To be able to repair the lifting cylinder, the entire 
piston rod must be removed and the oil seals 
must be replaced. The cab tilting pump is 
required to take out the piston rod.

Reconditioning of a lifting cylinder requires not 
only the use of the reconditioning kit, but also the 
reuse of a number of components.

Use a separate cab tilting pump to pump the 
piston in and out.

Disassembling lifting cylinder
1.

Remove the dust cap.

2.

Take the dirt scraper out of the lifting 
cylinder.
