The new Allen Screw is made of Titanium Grade 5 6Al4V certified U.S. derivation, the choice to use Titanium is due to the different thermal expansion compared to Steel; this will make it possible to unscrew/screw without problems the Allen Screw even with the hot engine.
It has a total length of 9mm of which 6mm are of thread and a protrusion from the crankshaft of only 3mm so as to avoid collisions with the tank in case of excessive flexion of the chassis.
The new geometry eliminates any rubbing between bearing/bell, in order to decrease the operating temperatures of the whole, in addition external diameter protects the bearing from dust and foreign bodies.
We recommend that you do not use any type of Threadlock and leave a game of 0.15/0.2mm in the coupling between Bell and Allen Screw.
We recommend to always use tools in GOOD Condition!!!
It can be used with any engine and mounted on all 1/8 Buggy models.
The weight is of 0.45g
