11.4.4 Replacing the connecting block or drain valve
The connecting block or drain valve must be exchanged if the assembly is damaged, if
continued and correct function is no longer guaranteed or if a permanent leak has developed
in the assembly. It is possible to convert from a connecting block to drain valve arrangement
and vice versa.
Procedure:
1. Much of the procedure is identical to the procedure involved in changing the hydraulic
uid including removal of pump carrier plate “O” with engine / motor. For this reason, we
recommend that you carry out this replacement as part of the uid change. The work
required to replace the connecting block or drain valve is performed at pump carrier plate
“O”.
2. Loosen union “N” securing the pipes to the connecting block or drain valve and unscrew
return line “M” from the connecting block.
3. Loosen securing screws “L” from the connecting block or drain valve and remove the
screws along with washers “K” underneath.
4. Now you can remove the connecting block or drain valve along with the seal underneath
and t the new connecting block or drain valve. It is possible here to convert from a
connecting block to drain valve arrangement and vice versa.
5. The new connecting block or drain valve is tted and connected to the pump carrier plate
in reverse order
6. To nish assembly, proceed as described in the “Replacing the hydraulic uid” chapter.
