At our Hydrostatic Pump Repair Site, we offer many types of Hydrostatic Transmission Repair and information relating to Hydrostatic Parts
Today we will discuss:

Sundstrand Sauer Danfoss Series 90 75cc Auxiliary Flange Charge Pump Cover

The service bulletin SB 2005-011 is to point out that it will no longer mark the flange “R” or “L” for the rotation anymore.

The pilot surface has changed on the cover. The right hand rotation on the charge pump cover will have one step. The left hand rotation on the charge pump cover will have two steps.

The P/N will remain the same.

The units that will be affected by this are

Series 90 42 thru 100cc pumps with auxiliary pad options.

Serial numbers are A-05-17-xxxxx

They are still interchangeable.
