5118238 VARIATOR MALOSSI MHR EQUIPO 2 PIAGGIO GILERA

With the variator & nbsp; MULTIVAR MHR TEAM 2 , don't be surprised if your scooter will buy one click, a linearity; change, greater & quot; tranquility & agrave; & quot; mechanics when driving at high speeds; and a constancy of performance unknown to the basic version!

The bush is; the point of contact between half-pulley and variator hub and must slide radially and axially without undergoing deformation.
In the light of this consideration we have improved the entire apparatus using cemented and ground steel bushings, both on the internal and external diameter, and, thanks to the use of 2 oil seals, the lubricating grease present in a tank touches the walls of the tank. ; hub bushing coupling ensuring minimum friction in any condition, as well as maximum efficiency performance.
The 22 mm variator hub is also; It has been improved in design: in fact, holes have been made that join the internal and external chambers for the grease to flow and increase lubrication.
This technology also allows to reduce tolerances and, consequently, also all the coupling games are perfected and optimized.
Inside the variator kit & egrave; there is a mobile half-pulley with a diameter of 99.5 made of a special die-cast aluminum alloy.
The contact surface between pulley and belt is; been finished with a diamond tool with extreme precision to ensure a constant coefficient of friction, calculated to prevent slippage of the belt and, at the same time, to avoid premature wear.

Why & eacute; can meet all the requirements of the countless possible calibrations in a racing vehicle, depending on the tracks and the specific engine set-up, Multivar MHR is supplied with two series of 6-roller kits and a contrast spring in pre-hardened chromium-silicon alloy steel with anticlockwise winding (racing). In addition, various springs of the same class with differentiated load are available as options.
