In general, 8.8 grade bolts are sufficient for correct installation. Under particularly harsh operating
conditions, grade 10.9 bolts can also be used.
If grade 10.9 bolts are used, make sure that the structure in which they are fitted is of adequate strength.
Do not use bolts graded higher than 8.8 to install gearboxes with mounting elements (casing, flange or foot)
made from aluminium.
20. Fill the gearbox with oil or top up as necessary, as instructed in the “LUBRICATION” section in this
manual.
21. Check that all service plugs are tightened to the torque values given in the following table.
