Sundstrand Sauer Danfoss Series 40 Adding an Orifice
Sundstrand Sauer Danfoss Series 40 Adding an Orifice to the Loop Flush Drain
It is a change in the variable motor housing that will let the amount of the loop flushing flow to be controlled. The housing has to be tapped to take in an orifice in the loop flushing drain passage within the housing.
This housing replaces the old one which wasn’t tapped. And the new and old housings you can change out. You will not be able to get the old housing any more either.
