We lubricate the threads of the flywheel mounting bolts with an anaerobic thread locker, having previously degreased the bolts and the threaded holes for them.

Tighten the bolts evenly crosswise in two steps:

  • First stage - tighten with a torque of 30 Nm (3 kgf.m)
  • Second stage - twisting to an angle of 80º

If possible, replace the flywheel mounting bolts
