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.
When Assembling
Assembly is the reverse of dismantling, but note the
following points:
1 If certain components have been renewed, it will be
necessary to check specified clearances and, if
necessary make adjustments at the appropriate stage
of assembly. Failure to make the necessary
adjustments could result in poor performance and/or
premature damage. Refer to Adjustments, following
these notes, for details of the components and
procedures involved.
2 When installing the gear assembly into spindle 2, align
the inner race of bearing 22 with the outer race already
installed in the spindle. Lower gently to avoid
damaging the bearing.
3 The outer race of bearing 21 is an interference fit in
hub 1. To install, position an aluminium rod A as
shown, at various points around the circumference and
tap gently until the race is fully seated.
4 When fitting the reamer bolts 19 to secure flange 3,
tighten them evenly and progressively so that the flange
remains square with its associated components.
5 Unless new snap rings 20 are being fitted (see
Adjustments) make sure that they are returned to the
position on flange 3 from which they were removed.
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 unit for at least twelve hours after assembly to
allow the adhesive to fully dry.
Ensure that all components are re-fitted to the positions from
which they were removed, paying particular attention not to
mix components from identical sets front and rear.
