B-Mod Pump Identification
This service manual is to be used for P1/PD Design Series B (B-mod) pumps.
In order to identify which series of pump you have, please refer to the Series
Designation spot in the P1/PD model code as shown below.
The design series is based on the type of control selected. B-mod pumps use
the C, L, and AM controls. All other control types are Design Series A (A-mod).
There are however two exceptions. Both exceptions are on the 45 & 60cc pumps.
One exception is when the load sense (L) or remote compensator (AM) is used
in combination with the torque limiting control (ALT or AMT). The ALT or AMT on
the 45 & 60cc pumps is still the A-mod design series. The other exception is if
the Universal “U” conguration model code option is selected with the 45 or 60cc
pump. On those two displacements, the Universal “U” option is also still an A-mod
design series.

"U" Universal Designation
For service information on A-mod pumps please refer to
Bulletin HY28-2665-02/SVC/EN. The latest edition can be found at
www.parker.com/HPS.
NOTE: A-mod and B-mod controls are NOT Interchangeable! Adapter block
is required to put a B-mod control on an A-mod or an A-mod control on a
B-mod pump. See Parts Kits page for adapter block part numbers.

These pumps are designed to operate in any position. For shaft up, contact factory.
The pump shaft must be in alignment with the shaft of the source driver and should be
checked with a dial indicator. The mating pilot bore and coupling must be concentric.
This concentricity is particularly important if the shaft is rigidly connected to the driven
load without a exible coupling.
Splined: The shafts will accept a maximum misalignment of 0.005 in (0.15mm) total
indicator reading. Angular misalignment at the external and internal spline axis must be
less than ± 0,002 mm per mm of shaft radius, ± 0.002 inches per inch of shaft radius.
The coupling interface must be lubricated. PARKER recommends lithium molydisulde
or similar grease. The internal coupling should be hardened to Rc 27-34 and must conform
to SAE-J498c, class 5 at root side t.
Keyed: High strength heat treated keys must be used. Replacement keys must be hardened
to 27-34 Rc. The key corners must be chamfered 0.032-0.040 in (0.81-1.0 mm) at 45° to
clear radii that exist in the keyway.
The P1/PD series is designed for inline-drive. Side loading on the shaft is not recommended.
If this is unavoidable consult your nearest Parker representative.
Connect inlet and outlet lines to the port block of the pump. The maximum case pressure is
2 bar (30 psi) continuous, 4 bar (60 psi) intermittent. The case pressure must never exceed
inlet pressure by more than .5 bar (7 psi). When connecting case drain line make certain
that drain plumbing passes above highest point of the pump before passing to the reservoir.
The case leakage line must be of sufcient size to prevent back pressure in excess of 2 bar
(30 psi) and returned to the reservoir below the surface of the oil as far from the supply inlet
as possible. All uid lines, whether pipe, tubing, or hose must be adequate size and strength
to assure free ow through the pump. An undersize inlet line will prevent the pump from
operating properly at full rated speed. An undersize outlet line will cause back pressure and
cause heat generation and increased noise. Flexible hose lines are recommended. If rigid
piping is used, the workmanship must be accurate to eliminate strain on the pump port block
or to the uid connections. Sharp bends in the lines must be eliminated wherever possible.
All system piping must be cleaned and ushed before installing pump. Make sure the entire
hydraulic system is free of dirt, lint, scale, or other foreign material.
CAUTION: Do not use galvanized pipe. Galvanized coating can ake off with continued use.
Although the P1/PD series pumps have very fast off-stroke compensator response, system
relief valves are recommended in all cases for safety considerations.
The uid recommended for use in these pumps has a petroleum base and contains agents
which provide oxidation inhibition and anti-rust, anti-foam and de-aerating properties as
described in Parker standard HF-1. Where anti-wear additive uids are specied, see
Parker standard HF-0.
90 V. I. minimum. Higher values extend the range of operating temperature but may reduce
the service life of the uid. Viscosity cannot be lower than 7 cSt.
Determined by the viscosity characteristics of the uid used. Because high temperatures
degrade seals, reduce the service life of the uid and create hazards, uid temperature
should not exceed 230°F (110°C) at the case drain.
The pump is self-lubricating and preventative maintenance is limited to keeping system
uid clean by changing lters frequently. Keep all ttings and screws tight. Do not operate
at pressures and speeds in excess of the recommended limit. If the pump does not
operate properly, check the troubleshooting chart before attempting to overhaul the unit.
Overhauling may be accomplished by referring to the disassembly, rework limits of wear
parts, and assembly procedures as provided in this service manual.
Fluid must be cleaned before and continuously during operation, by lters that maintain a
cleanliness level of ISO 20/18/14. Better cleanliness levels will signicantly extend the life
of the components. As contaminant generation may vary with each application, each must
be analyzed to determine proper ltration to maintain the required cleanliness level.
