Vespa PX PE T5 Gearbox Parts
The gearbox is one of the most important components inside a classic Vespa engine.
The gearbox allows the rider to select the correct gear for starting, accelerating, cruising and stopping.
Scooter Vista stocks a range of Vespa PX, PE & T5 gearbox parts, including:
- Gearbox gears
- Gearbox shims
- Gear selector components
- Cruciforms
- Selector shafts
- Selector boxes
- Gearbox covers
- Layshafts
- Gear shafts
- Bearings
- Bushes
- Circlips
- Washers
- Spacers
- Gearbox hardware
If you're rebuilding an engine, it's important to inspect the complete gearbox rather than simply replacing one obviously worn component.
Vespa Gearbox Gears
The gearbox gears are responsible for providing the different ratios used by the Vespa transmission.
Worn gearbox gears can result in:
- Difficult gear selection
- Noisy transmission
- Gears jumping out
- Excessive backlash
- Damaged gear teeth
- Poor transmission operation
When rebuilding a gearbox, inspect the teeth and mating surfaces carefully.
If the gear faces or teeth show significant wear or damage, replacement should be considered rather than simply reusing the old components.
Vespa Gearbox Shims
Vespa gearbox shims are used to correctly control the end float of the gearbox gear stack.
Correct gearbox shimming is important because excessive movement can contribute to poor gear selection and accelerated wear.
Scooter Vista stocks gearbox shims for Vespa PX, PE and T5 applications in different thicknesses.
When rebuilding a gearbox, the correct clearance should be checked rather than simply fitting the same shim that was previously installed.
The correct shim thickness depends on the condition and dimensions of the gearbox components, so the gearbox should be measured during a rebuild.
Vespa Gear Selector Parts
The gear selector mechanism transfers movement from the gear control to the gearbox.
Components can include:
- Gear selector
- Selector shaft
- Selector box
- Selector cover
- Selector arm
- Selector components
- Selector bearings
- Selector bushes
- Selector hardware
Worn selector components can contribute to excessive play or difficulty selecting gears.
Replacement Piaggio gear selector crosses are available for PX, PE, Arcobaleno, T5 and Cosa applications.
Vespa PX PE T5 Cruciform / Gear Selector Cross
The cruciform, also known as the gear selector cross, is a critical component inside the Vespa gearbox.
It engages with the gearbox gears and allows the selected gear to transmit drive.
A worn cruciform can contribute to gears jumping out, particularly under load.
When rebuilding a high-mileage gearbox, inspect the cruciform carefully along with the gearbox gears and selector shaft.
If the cruciform is worn, replacing it while the engine is already apart can help prevent having to dismantle the gearbox again later.
Vespa Gear Selector Shaft
The selector shaft transfers the movement from the external selector mechanism to the internal gearbox selector.
During an engine rebuild, inspect the shaft for:
- Wear
- Corrosion
- Damage
- Excessive movement
- Worn sealing surfaces
A damaged selector shaft can also affect the operation of the gearbox and may contribute to oil leaks.
Vespa Gear Selector Box
The gear selector box is mounted externally on the engine casing and connects the gear cables to the selector mechanism.
Scooter Vista stocks Vespa PX, PE & T5 gear selector box components and related hardware.
When rebuilding the selector mechanism, inspect the selector box, cover, shaft, cable connections and seals.
Vespa Gear Selector Box Cover
The selector box cover protects the selector mechanism and helps retain the components inside the assembly.
Replacement covers are available for different Vespa applications, including PX and earlier large-frame models.
A replacement cover can be particularly useful during an engine restoration where the original has become damaged or corroded.
Vespa Gearbox Bearings
The gearbox relies on bearings to support the rotating components.
During a complete engine rebuild, inspect all gearbox bearings for:
- Roughness
- Play
- Noise
- Corrosion
- Damage
If an engine has covered significant mileage or the gearbox is already dismantled, replacing worn bearings can be worthwhile.
Vespa Gearbox Circlips & Washers
Circlips, washers and spacers help retain and correctly position the gearbox components.
These are small components but are essential to the correct assembly of the gearbox.
Whenever a gearbox is dismantled, check that:
- Circlips are undamaged
- Washers are correctly positioned
- Spacers are present
- Components are assembled in the correct order
Never reuse damaged or distorted retaining components.
Vespa PX PE T5 Layshafts
The layshaft, sometimes referred to as the gearbox shaft or rear axle shaft, forms a major part of the Vespa transmission and final drive.
Scooter Vista stocks suitable Vespa PX, PE, EFL and T5 layshaft/rear driveshaft components.
A worn or damaged layshaft should be inspected carefully during an engine rebuild.
Check the splines, bearing surfaces and threads for signs of wear or damage.
Vespa Rear Hub Parts
The rear hub transfers the final drive from the gearbox to the rear wheel.
Scooter Vista stocks a range of Vespa PX, PE & T5 rear hub parts, including:
- Rear hubs
- Rear hub nuts
- Hub washers
- Hub spacers
- Rear hub oil seals
- Dust plates
- Wheel nuts
- Wheel washers
- Hub hardware
- Rear brake components
The rear hub is a particularly important area to inspect because it combines the final drive, rear wheel mounting and braking system.
Vespa PX PE T5 Rear Hubs
Replacement rear hubs are available for PX, PE and T5 applications.
Scooter Vista stocks standard and strengthened rear hub options.
For example, the Scootopia strengthened PX Disc, EFL and T5 rear hub is reinforced through the centre of the hub and features larger fins. It was developed with higher-powered Vespa engines and sidecar or tuned-cylinder applications in mind.
A strengthened rear hub can therefore be worth considering for a performance Vespa rather than simply replacing a standard hub with another standard component.
Vespa Strengthened Rear Hubs
Modern Vespa engines can produce considerably more power than the original engines these scooters were designed around.
A strengthened rear hub can provide additional support for riders running:
- Performance cylinder kits
- Tuned PX engines
- Higher-output engines
- Sidecar combinations
- Performance exhausts
- Long-distance touring setups
The Scootopia strengthened EFL-style rear hub uses a 30mm oil seal and was originally fitted to P-range and T5 models from 1984 onwards.
Always check the correct oil seal specification when changing between different hub designs.
Vespa Rear Hub Oil Seals
The rear hub oil seal prevents gearbox oil from escaping through the rear hub assembly.
A failed rear hub seal can result in:
- Oil leaking into the brake area
- Contaminated brake shoes
- Gearbox oil loss
- Oil around the rear hub
- Rear brake performance problems
Different PX, PE and T5 hub arrangements use different oil seal sizes.
Scootopia's PX/PE/T5 oil seal set includes several rear hub seal applications, including early 27 x 47 x 6 and later 30 x 47 x 6 seals.
Always check the hub and oil seal specification before ordering.
Vespa Rear Hub Dust Plates
The rear hub dust plate helps protect the rear hub and brake assembly from contamination.
Some PX, T5 and EFL arrangements use a dust plate with a felt sealing component.
Scootopia's PX/PE/T5 oil seal set includes a T5, Cosa and EFL rear hub dust plate with felt.
During a rear hub rebuild, inspect the dust plate and replace damaged or missing components.
Vespa Rear Hub Nut
The rear hub nut secures the hub and rear wheel assembly to the gearbox shaft.
This is a critical fixing and should always be correctly installed and secured.
Replacement rear hub nuts are available for PX and T5 applications, with the PX/T5 nut specification listed as M16 x 1.25 on compatible later models.
Never substitute an incorrect nut or locking arrangement.
Vespa Rear Hub Nut Locking Kit
The rear hub nut requires the correct locking arrangement to prevent it from loosening.
Replacement locking kits can include:
- Hub nut
- Lock washer
- Split pin where applicable
- Associated retaining hardware
Italian-made replacement rear hub nut locking kits are available for PX, T5 and other compatible Vespa applications.
Always check the correct locking system for your specific hub and gearbox shaft.
Vespa Rear Hub Spacer Washer
The rear hub spacer washer is an important component of the rear hub assembly.
It provides the correct spacing between the hub and associated components.
Scooter Vista's PX/PE/EFL/T5 rear hub set includes a rear hub spacer washer together with the hub, wheel rim nuts and washers, hub nut cap and oil seal.
Do not omit the spacer washer when assembling the rear hub.
Vespa Rear Hub Wheel Nuts & Washers
The rear wheel is secured to the hub using the appropriate wheel nuts and washers.
During a restoration, inspect the wheel nuts and washers for:
- Damaged threads
- Corrosion
- Incorrect washers
- Previous damage
- Poor fit
Replacing worn hardware is worthwhile when fitting a new rear hub.
Vespa Rear Hub Brake Area
The rear hub is closely associated with the rear brake assembly.
When replacing or rebuilding the hub, inspect the surrounding brake components for signs of:
- Oil contamination
- Wear
- Corrosion
- Damaged brake components
- Incorrect adjustment
If gearbox oil has leaked past the rear hub seal and contaminated the brake shoes, simply replacing the seal may not be enough. The contaminated braking components should also be inspected and replaced where necessary.
Vespa Gearbox & Rear Hub Oil Leaks
Oil leaks around the rear wheel area can sometimes be traced to the rear hub oil seal.
Common signs include:
- Oil around the rear hub
- Oil inside the brake drum
- Oil contamination on brake shoes
- Low gearbox oil level
- Oil running down the engine casing
If you find an oil leak, don't automatically assume the hub seal is the only possible cause.
Inspect the complete area and determine where the oil is originating before replacing parts.
Vespa Gearbox Rebuild Parts
If you're rebuilding a PX, PE or T5 engine, it can make sense to inspect the complete gearbox while the engine cases are apart.
A gearbox rebuild may involve checking or replacing:
- Gearbox gears
- Cruciform
- Selector shaft
- Layshaft
- Gearbox shims
- Bearings
- Circlips
- Washers
- Selector components
- Oil seals
Replacing worn components while the engine is apart can save time and labour later.
Vespa PX PE T5 Gearbox Servicing
Gearbox condition is important for both standard and tuned Vespa engines.
During servicing or an engine rebuild, check:
- Gearbox oil level and condition.
- Gear selection.
- Selector movement.
- Gearbox end float.
- Gear teeth.
- Cruciform condition.
- Layshaft condition.
- Bearings.
- Oil seals.
- Rear hub components.
If the engine is already dismantled, take the opportunity to inspect components that would otherwise be difficult to access.
Vespa Gearbox & Rear Hub Parts for Restoration
A complete Vespa restoration often involves replacing many of the small transmission components that have worn over decades.
During a restoration, inspect the:
- Gearbox
- Rear hub
- Selector mechanism
- Layshaft
- Gearbox shims
- Bearings
- Oil seals
- Hub nut
- Hub washer
- Hub spacer
- Rear brake area
This is particularly important on scooters that have been stored for many years or have an unknown service history.
Standard or Performance Vespa Gearbox & Rear Hub Parts?
The correct components depend on how the Vespa will be used.
For a standard restoration, original-style replacement gearbox and hub components may be the best choice.
For a tuned engine, however, it is worth considering stronger components where appropriate.
A performance Vespa may benefit from:
- Strengthened rear hub
- Quality gearbox components
- Correct gearbox shimming
- Upgraded bearings
- High-quality oil seals
- Correctly matched gearing
The engine specification, intended use and final gearing should all be considered when rebuilding the transmission.
Choosing the Correct Vespa PX PE T5 Gearbox Part
Before ordering, check:
Vespa model
Engine size
Year
PX or PE specification
T5 specification
Early or late gearbox
Gearbox shaft specification
Rear hub type
Oil seal size
Standard or performance application
This is especially important when dealing with rear hubs and oil seals because different PX, PE and T5 configurations can use different dimensions.
For example, later EFL/T5 hubs use a 30mm oil seal arrangement, while earlier rear hub applications can use a 27 x 47 x 6 seal.
