DDP component identification
The DDP096 is a 12-cylinder radial piston hydraulic pump.
The 12 cylinders are arranged into 3 banks (A, B and C) with A being the closest to the mounting flange.
The cylinders are identified by their bank followed by their pumplet number (1, 2, 3 or 4). For instance,
the cylinder from the pumplet 3 positioned in the bank C (the closest to the endcap) is the cylinder C3.
The figure below shows the pump housing with the cylinder labels. These labels are used to identify any
specific components of the pump (e.g., the coil B2). Note that the pumplet numbers are visible on the
pump housing when looking at the pump from the endcap.

Depending on the type of endcap, the pump can either provide flow to one outlet or multiple
independent outlets. Refer to the
manual, BC306384089197, for more
information.
Wiring harness
General harness information
The wiring harness of DDP096 pumps requires the three following sub-harnesses:
•
Two coil harnesses (“A” and “B”)
•
One sensor harness
These wiring harnesses can be individually replaced if needed and are supplied with cable ties (securing
one harness branch to the pump housing or to another branch). The wiring harnesses are tied together at
the main anchor.
Most of the wiring harness is covered in black nylon braid for protection. There is a gap of approximately
10 mm between the end of the braid and each connector to ensure that each harness branch is
connected to the correct coil or sensor. Each connector can be identified by the colors of its wires (visible
in the unbraided part), the number of wires, and the length of the branch.
When securing a cable tie, make sure to tension it to form a snug fit but not to crush the wires. The loose
end of the tie should be cut to maximum 1 mm of protrusion.
In certain scenarios, lifting brackets can restrict access to anchoring tie screws and may need to be
temporarily removed during servicing. They should be torqued back to the value specified in
.
