11. Apply a generous amount of Molykote Multilub
(art. no. 1236 0011-127) on the nut, washer and draw-rod
bolt. Remove any excess Molykote Multilub with a rag.
12. Tighten the nut to 20 Nm and measure the distance a,
from the top of the nut to the top of the draw-rod bolt.
13. Continue tightening the nut until the measured distance
b = a + 9 mm. Each turn corresponds to an extension of
2 mm.
14. Continue at section 2.11 to ground the bushing flange.
WARNING
If the measured distance b = a + 9 mm is not
achieved before reaching 160 Nm, this indicates that
the threads are too poorly lubricated. If the threads
are not damaged, remove the nut and draw-rod bolt
to apply more Molykote Multilub and tighten again.
If the threads are damaged, the nut and draw-rod
bolt must be replaced.
Please contact the supplier if the specified values cannot be
attained after following the instructions above.
