Important
The pushrods must be installed in the original
direction at assembly. This is because the
pushrods have a different degree of hardness at
each end. A paint stripe identifies the upper end
of the pushrod. If the paint stripe is not visible,
mark the pushrods on the upper end as they
are removed.
Mark the pushrods so they can be installed in
the same location at assembly.
