Sundstrand Sauer Danfoss Series 90 – Side Washer Change
This service bulletin SB 1994-018 for the 130cc pumps, the washers that are under the side cover screws have been taken off all the series 90 42 – 130cc variable pumps.
Always if you take off the side cover screws for any reason, they have to be replaced. The coating that seals and keeps the screws, wears off when are screws get taken off.
The screw length changed on 55cc- 100cc pumps, so take note that the washers are thrown away during repair. The right screw is in the overhaul seal kits.
If you have any questions, on this topic…please let us know.
