The Piaggio 478324 complete timing cover is the original spare part for the Piaggio group's 50-125 4-stroke engine: a die-cast aluminum cover supplied complete with an oil seal and chain guide shoe. It covers twenty years of scooters: Piaggio Liberty, Zip, Fly, and Typhoon 4T, Vespa LX, S, Primavera and Sprint 50, Aprilia Scarabeo, Sport City ONE, SR Motard and Mojito, up to the Euro 5 models currently in production. Product code 478324.

✓ Strengths

• Original Piaggio spare part – code 478324 as listed in the catalog for these engines, with the same mating dimensions as the factory-fitted part.
• Complete and ready – oil seal already pressed into its seat and chain guide shoe already mounted: no parts need to be salvaged from the old cover.
• Die-cast aluminum – rigid body with ribs, flat sealing surface, mounting holes with machined seats.
• One code for many models – the same cover fits the 50 4T of Liberty, Zip, Fly, LX, Primavera and Sprint, and the 100-125 4T of Fly, Liberty, Zip, Scarabeo and Mojito.
• Replacement without surprises – simply remove the old cover, clean the surface, install the new one with its gasket, and tighten in a cross pattern.

Who is it perfect for?

It is the spare part for those who find oil on the timing side of a Liberty, Zip, Fly, or Vespa 50 4T and discover that the cover's oil seal has failed, or for those who open the engine for the timing chain and find the shoe worn out or the cover cracked from a fall: with the complete part, everything is reassembled new at once, without having to look for separate oil seals and shoes. It is useful for workshops that service Piaggio 50 4T models, which are among the most popular scooters in Italy, and for those putting a Scarabeo, Mojito, or Vespa ET4 back on the road with the original code specified by the manufacturer.

Frequently Asked Questions

Which scooters does the Piaggio 478324 timing cover fit?
Code 478324 is listed in the Piaggio catalog for the 50-125 4-stroke engine found in Piaggio Liberty, Zip, Fly, Typhoon 4T, Free 100, Sfera 125 and Hexagon LX4, Vespa 50 4T, ET4, LX, LXV, S, Primavera and Sprint 50, and Aprilia Scarabeo 50 and 100, Sport City ONE 50, SR Motard 50 and Mojito 125, as shown in the table.

What does "complete" mean?
It means that the cover arrives already assembled with the oil seal pressed into its seat and the chain guide shoe installed, as shown in the photos. These are the two components that wear out and often require the cover to be replaced: here they are new and already in position, so there is nothing to transfer from the old part.

Is the gasket included?
No. The gasket between the cover and the crankcase is not included and must be purchased separately with the code specified for your engine: a new gasket is always used during reassembly, because the old one remains deformed and does not guarantee oil tightness. The screws are also not included: the original ones are reused if they are intact.

How do I know if the cover needs to be replaced?
Typical signs are oil seepage on the timing side that doesn't stop by changing the gasket, because the oil seal is leaking, a metallic chain rattling noise due to a worn shoe, or a crack or broken mounting lug after a fall. In all these cases, the complete cover solves the problem with a single part.

Is it an original Piaggio spare part or an aftermarket equivalent?
It is the original Piaggio spare part with code 478324, new and never fitted, the same one specified by the manufacturer for these engines. It is not a reproduction cover: the casting, sealing surface, oil seal, and shoe are those of the original equipment, and the code is still listed for Euro 5 models in production. It is shipped from Italy with an invoice.

Is it also suitable for my 2-stroke Liberty or Zip?
No. Code 478324 only applies to 4-stroke engines: Liberty 2T, Zip 2T, Typhoon 2T, and LX 2T models have a different engine without a timing chain, and therefore do not use this cover. Check your owner's manual to see if your scooter is a 4T, and if in doubt, send us your VIN before ordering.
