Sb-9507 - Sauer Danfoss Series S90 180 cc Service & Parts Manual

PRODUCTS AFFECTED:
SUBJECT:
Charge Pump Design Change
DESCRIPTION:
To improve efficiency and reliability, the number of charge pump parts in the Series 90
180 cc pump is being reduced. The charge pump design is being changed to make the
outer port plate an intergal part of the charge pump cover and to eliminate the distance
plates.
For auxiliary pad options, the new charge pump cover is rotation dependent. The cover
will be marked either left hand (L) or right hand (R). The non-auxiliary pad cover is not
rotation dependent.
The complete charge pump assembly can be interchanged with corresponding hardware.
However, piece parts are not interchangeable.
