Clutch holding tool Vespa Smallframe V50, PV, ET3, PK, PK XL - Item number 7675436

Modern day cylinder kits and full expansion chambers give amazing power outputs to the Smallframe vespa Setups like the Polini Evo used with the Big bertha expansion chamber like on ours Generation XI, give more than 24 Nm torque at the rear wheel.

To get the power from the top end to the bottom emd you have the clutch unit. With the high power outputs the clutch is under enormous stress. This connection has to be built with the care needed to get it reliable and long lasting.

Good practice these days is to grind in the clutch on the auxiliary shaft with valve grinding paste and afterwards to tighten down the primary drive and clutch nut to 70 Nm.

Specially for these high torque settings we have clutch and primary drive nuts in high tensile steel. These even sustain torque settings much higher htan 70 Nm. Because these are collar nuts that are usually used securing washers are no longer needed. Good practice is to use screw retaining glue.

To avoid any damages to the clutch basket and primary drive while putting such high torque figures thru the wrench, we have a new clutch holding tool now.

With this new tool inner baskets of the V50 / XL1 clutch
