Sundstrand Sauer Danfoss Series 90 100 CC Pumps & Motors Charge Pump Change

In BLN – 10107 Revision B talks about the change in the charge pump design in pumps 55cc thru 130cc frame sizes. The change is in the outer port plate is not the integral part of the charge pump cover and the distance plates are done away with.
The change is effective as follows:
55cc 93-10
75cc 93-10
100cc 93-15
130cc 93-34

Options on the auxiliary pads are that the charge pump cover is rotating dependent. The cover is either LH or RH. Non- auxiliary pad cover is not rotation dependent.
The charge pump Shaft also has to be replaced, when switching over to the new style. The complete assembly can be interchangeable with hardware 89-17 and future parts. On the flip side, piece parts cannot be interchangeable.
And as new parts come in, the older parts are no longer available.
The chart will show the new replacement parts.
