Main Pump (Denison T6DMY Series)
REASSEMBLY
NOTE:
Coat all parts except seals and back-up rings with clean hydraulic fluid to facilitate
assembly and provide initial lubrication. Use small amounts of petroleum jelly to hold O-
rings in place during assembly.
NOTE:
To reverse direction of a new cartridge kit, simply reverse location of inlet and outlet
support plates, and realign cartridge with cover. See steps 1H through 1J.
1. Cartridge reassembly - The direction of rotation is as viewed from shaft end, right-hand rotation is
clockwise; left-hand, counterclockwise.
NOTE:
If locating pins were removed from inlet support plate, install new pins with locking flutes
within inlet support plate. Drive new pins into support plate, with a soft tip hammer.
A. Place inlet and outlet support plates
on a flat surface as shown in Figure
20. Install seal packs into cavities
with seal retainer surface up. (O-
rings facing downward into cavities.)
B. Place a flex side plate over each of
support plates with bronze wear
surface facing up. Align scribe marks
to make sure correct flex side plate is
used with correct support plate.
NOTE:
Flex side plates develop a wear
pattern with rotor and vanes
and should not be
interchanged.
C. For right-hand rotation units, set rotor
on flat wooden board with arrow
pointing right. (For left-hand rotation
arrow should point left.) Assemble
vanes and inserts into rotor in
reverse order. (See Figure 21.) Make
sure sharp chamfer edge of each
vane leads in direction of rotation. All
vanes must move freely in rotor slots
with no evidence of bind.
D. Assemble cam ring over rotor and
vanes with arrow pointing in same
direction as rotor. Lubricate top
surface of rotor and vanes liberally
with system fluid.
IMPORTANT
During handling and shipping of precision machined cartridge parts, it is possible to raise
burrs on sharp edges. All sharp edges on parts of a new cartridge kit should be stoned
before installation.
