Sundstrand Sauer Danfoss Series 90 Side Cover Change
Sundstrand Sauer Danfoss Series 90 100cc Side Cover Change
Sundstrand is changing the side cover screw from all of its Series 90 42-130cc variable pumps.
As always the side cover screws if they are take out for any reason, they have to have new ones put back in. The resin coating they put on there at the factory is the reason they have to have new ones put back in once they are taken out. That resin seals the screws and when that is broken when you take out the screws, the seal is not longer there.
The old screw length has changed on 55 -100 cc pumps and throw away the washers also if you are repairing your unit. The correct screw is in the seal kit.
