Hydraulic Pump/Regulator
Assembly
Clean each part in a suitable solvent and dry using
compressed air.
Inspect all parts and renew as required.
Care must be taken not to let dust or dirt adhere to parts
after cleaning and that parts do not become dented,
scratched or damaged.
Fit new ‘O’-rings, plugs, packing, oil seals and fastener
seals.
Apply Lithium grease to all new oil seals (particularly the lip
areas) and ‘O’-rings, and clean hydraulic fluid to all sliding
parts before installation.
All tapped holes and gasket faces should be thoroughly
degreased by washing, as liquid packing and adhesive is
used on all gasket surfaces and threads.
Apply adhesive to the final few threads of a bolt or screw. Do
not apply excessive amounts of adhesive. Wipe off any
surplus.
Leave the pump for at least twelve hours after assembly to
allow the adhesive to dry fully.
Ensure that all components are re-fitted to the positions from
which they were removed, paying particular attention not to
intermix components from identical sets front and rear.
1
Install regulator piston
23
and bridging piece
29
into the
front of pump housing
1
.
Note:
Make sure the bridging piece is orientated as shown
on page 14 - 3.
2
Fit ‘O’-ring
82
and back-up ring
94
to stopper
24
. Insert
the stopper into pump housing
1
.
Fit ‘O’-ring
85
and back-up ring
95
to stopper
25
. Insert
the stopper into pump housing
1
.
Note 1:
Install stoppers
24
and
25
with the tapped centre
holes facing outwards.
Note 2:
The back-up ring is fitted to the end of the stopper
nearest the tapped hole, with the ‘O’-ring innermost.
Note 3:
The stoppers must be fitted flush with the housing
to prevent damage to the ‘O’-rings.
