👨🔧 Tip in Michel (the corner of the expert)

* "Hi the 2-stroke gold! The screw M7x1x12.5 of the reinforcing disc, it is typically the screw never to neglect or replace with a standard BTR screw of DIY! The step of M7 x 1,00 and the head imprint are very specific.

My stand trick for replacing and mounting these M7 screws (detail 12): absolute degreasing, strong net brake and torque tightening !

When you disassemble the bell shock disc, these screws are subject to huge shear stresses at each gas stroke. If only one screw loosens on the track, it rides against the housing or destroy the rubber shock absorbers !

When reassembling:

1. Clean the M7 tapping in the bell with brake cleaner and a blow gun (there must be no drop of oil).

2. Systematically apply a drop of forty brake (red) on each new M7 screw.

3. Tighten the cross screws at the torque wrench. If a screw head is marked during disassembly, change it directly, do not wait for it to be at the next interview! "*
