4.13 Changing the seals on the hydraulic rams

Figure 4.22

NOTE!

During service work on the hydraulic system, the wing sections and the drill must be fully

lowered, with no pressure in their hydraulic systems

Remove the rams completely from the drill before changing the seals.

Loosen and unscrew the piston rod guide (A) using the special tool (B).

Withdraw the piston rod and change the seals. In the event of external leakage, change the inner
and outer seals on the piston rod guide (A). In the event of internal leakage, change the seals
on the piston (C).

Refit the ram.

In the event of external leakage, also check that the rams two external connections have flat and
smooth surfaces.
