The total weight of the full piston PRO with rack in M.I.M. stands at 14.40gr, which makes it one of the lightest full pistons on the market. The structure, both as materials and as geometry instead, make it one of the most resistant in the world to the stresses inside the GearBox. The PRO piston in DELRIN TopMax is compatible with all the GearBoxes V2 and V3 on the market and with all types of similar GearBoxes.
The rack in M.I.M., has been worked and made with the second missing tooth and the third tooth already lowered with a 30 ° bevel, in this way a perfect working cycle and engagement with the sector gear is generated. Metal Injection Molding allows to obtain components, normally obtained from bars, forged and / or molded, with greater and wider geometric flexibility while maintaining the characteristics of resistance and durability practically identical to those of the CNC process.
TECH TIP. The rack and the length of the PRO TopMax piston have been designed for perfect coplanarity with the teeth of the sectoral gears. This design peculiarity can lead, on some GearBoxes, to the fact that the piston touches the back of the GearBox shells before reaching the moment of release. For this reason, we STRONGLY RECOMMEND that the piston is free to disengage from the sector gear before it reaches the back of the GearBox shells. If this were not the case, but regardless in the opposite case, TopMax Elaborazioni RECOMMENDS to eliminate at least 1/2 release teeth (depending on the need and the GearBox) on all the preparations / configurations in which our PRO piston is used.
The STRESS-TESTS carried out on the full PRO piston with M.I.M. have been performed with springs and R.O.F. higher than those envisaged and by the Italian legislation on the matter, so the product will guarantee reliability, resistance, durability and very high performance even with decidedly high configurations.
