Sundstrand Sauer Danfoss Series 40 – Servo Adjustment Screw

This affects M46 variable and tandem pumps.

The change to the screw is to make it stronger to adjust for the depletion of performance. Also the spring guide has been updated as well. It can be used with the older version of the servo screw.

If you need to replace the servo screw, you will need to replace the spring guide also. The old spring guide will not work with the new servo screw.

The older servo screw and spring guide are no longer available.
