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.
