Sundstrand Sauer Danfoss Series 40 High Pressure Relief Check Valve Change

The change is due to making it a higher performance unit and cost effective part.

It will effect the housing and relief/check valve on M46 pumps and the center section on 90-7001. The parts are “NOT”  interchangeable.

The older design will no longer be available.

If you have the older housings and center  sections, you will need to convert to the new models when it is time to replace parts. You can still get the relief check valve for the older units.

The newer design will only be sold as a kit. It has a spring,relief check valve and plug.
