Tightening Torques
Nuts and Bolts (for ISO strength category 10.9)
Tighten nuts and bolts at the torques shown on the table below, unless otherwise specified
in the text.
�
Tightening torques when mounting plastic covers differ from the values on the table
below. Consult a Takeuchi sales or service outlet. Tightening too strongly will break the
cover.
�
When replacing nuts and bolts, replace them with nuts and bolts of the same size and
standards.
�
Tighten nuts and bolts alternately (top, bottom, left then right) or in 2 or 3 times so that
they are tightened uniformly.
