Preview: Engine casing bolt M7 x 80mm -VESPA- 56-24mm

Description

The Vespa housings are fixed in the classic way, mostly by tie rods. Unlike stud bolts, tie rods are not screwed into the housing, but are guided through a bore hole that runs through both housing parts to be connected, and in the case of the Vespa motors are screwed on one side. The other side of the housing bolt (tie rod) has a head without a wrench but with an anti-twist device.
This technique minimizes the continuous effect on the thread, the torque distribution in the housing is better, but the main advantage is of course the more cost-effective production of the housing, because no threads have to be set here.

The 80mm engine housing bolt shown here is the second longest bolt used in the PX Lusso, MY, 2011, Cosa and T5 engine housings.
It is mounted at the height of the shock absorber mount.

The PX old models do not need this bolt.
In the small frame motors it is used at the lower side of the engine block.
