SIEMENS XBZ ¾ “  three way valve mates with SBC28.4 -  SBC28.2 motor

Contrary to what SIEMENS and hydraulic service people said the valve is fully repairable.

You will need:

A big vice and a big pipe wrench. That’s because you need a lot of force to break the seal glue from screw threads.

Two new O-rings with some kind of grease for lubricating.

You will also need Teflon tape or Teflon seal liquid for seal in place of producer’s seal glue.

That’s all.

 

 

There is no need to remove all junctions, just the upper part of one of the two T sections to reach the part

With the two O-rings that need replacement.
