DRAINING THE OIL
This operation cannot be carried out with the fork installed on the motorcycle.
We recommend loosening the fork cap a little before removing the fork leg from
the fork yokes.
• Remove the fork leg from the fork yokes according to the procedure in the motorcycle
owner’s manual.
• Clamp the fork leg in the vice.
• Remove the fork cap ( 48 ) with the 19 mm spanner.
• Slowly lower the slider on the stanchion tube.
• Push the guide spring cap ( 20 ) and the spring ( 21 ) downwards, so that you can
reach the locknut ( 23 ) with the 19 mm spanner.
• Holding the locknut ( 23 ) with A 19 mm spanner, use another 19 mm spanner to
unscrew the fork cap ( 48 ) completely.
• Remove the fork cap ( 48 ), the guide spring cap ( 20 ), the spring ( 21 ) and the
preload tube ( 25 ).
• Remove from the rod’s edge ( 32 ), the adjustment return inner rod ( 31 ).
• Free the fork leg ( 5 ) from the vice and tip it into a container of a suitable size to
drain the oil; pump the fork to help the oil ow out.
The R5051AC is available as spare part: if you tighten it on the rod’s edge, you
can make the rod extraction from the inner part of the slider easier.
Check appearance, density and quality of the old oil to get an idea of the oil seal
and guiding elements condition. If the oil is dense and dark with solid particles
in it, you will have to replace the guide bushings and the sealing elements.
Paragraph 4.11 describes the
procedure for assembling and
lling with oil.
