Vespa Engine and Parts
Engine and parts: The heart and driving force of the Vespa, the Engine and parts section is located at the rear of the vehicle, firmly anchored to the frame by two pins:
the first, at the end of the central tunnel and the second to the shock absorber.
Given its importance, the engine is composed of numerous and different parts. In a complete overhaul, it is good to check the wear of all the spare parts, paying particular attention to the crosspiece,

A chamfer has been machined on the corners of the ends of the cross to preserve the integrity of the gears and the selector
The cross has slightly larger dimensions compared to the original ones which may require small adjustments to be made on the wheel axle before assembly.

Equipped with a self-locking cone capable of stably coupling the crankshaft and pinion.
With this system, the key does not need to be used. Ideal
for modified engines and
for crankshafts damaged at the key location.
The cone is compatible with the entire range of Piaggio crankshafts
and interchangeable. It is recommended to apply strong type locking
on the fixing nut and to respect the tightening torque of 60-70 Nm.
For disassembly, a 3-thread puller is required, not included.

Perfectly compatible with all models with a long splined lever, it increases the operating pressure by significantly "softening" the lever.
If you have a short lever available, proceed as follows:
Disassemble by removing the elastic pin, cut the lever in half with a hacksaw, then cut a 10/12mm sheet metal plate and weld it. You will then have a lever made up of 3 pieces longer than the original by about 10/12 mm.

The gear lock is used to easily block the primary transmission of your Vespa smallframe engine.
By placing the component between the sprocket and the gear, thanks to its asymmetrical shape,
we can securely and stably block the normal rotation of the gears.

The pressure plate is made from solid anticorodal aluminum with hard oxidation treatment. Designed
for all central spring/double central spring clutches, it has a
special shape that prevents the ring from coming out and directs oil onto
the clutch pack discs, improving their performance. Compatible with all clutch covers for smallframe Vespa.

The construction of the teeth is carried out with a module gear shaper tool
1.5 with relative corrections for the pinions added to the original
pair.
The width of the tooth has been widened (1 mm towards the inside) to
achieve greater resistance without compromising smoothness.
The spring seats have been revised to use springs with square wire.
The greater stroke of the shock absorber protects the gearbox and cruise.
In the center, there is a roller bearing on the most stressed part and a guide bushing on the shaft end. This solution
allows the bell to be compatible with the original starter gears.

Born for the soft use of the vespa, they reduce the elastic effect of the
traditional rubber support ensuring excellent riding comfort. The elastic joints are contained by a cup made
of acetal resin which further dampens vibrations
without compromising wheel alignment.
The central stainless steel shaft is fixed to the frame with 2 M10 screws replacing the original through bolt.
Designed for Quattrini engine casings, they are compatible with Piaggio
engine casings. Check the size of the seat, it must not exceed diam.

The new reinforced axle shaft for Vespa smallframe engines is
made of high-strength steel with a corresponding vacuum carburizing
treatment.
The material used and the new sizing make the shaft
particularly suitable for tuned engines or with displacements greater
than normal (even up to 250 ccm)
Today, thanks to recent investments by some manufacturers, it is
possible to find on the market a wide range of very powerful thermal groups
that even exceed 40 horsepower.
I remind you that the Vespa smallframe engine was designed to last over
time and its power hardly exceeded 10 horsepower.
With these power increases, it is essential to adjust all mechanisms to avoid breakages and premature wear.
Example of the new sizing. The threading has also been increased to M16x1.25
