Piaggio 880727 Water Pump Cover Gasket – Beverly, MP3, X10, and SR GT 400

The water pump cover gasket is the flat seal that closes the water pump housing on the engine: a grey shape with a wide central opening and five mounting holes. It is an original Piaggio Group spare part for 350 and 400 4V engines, and it must always be replaced whenever the pump is opened. Product code 880727.

✓ Strengths

• Original Piaggio Group spare part – in the official spare parts catalogue, it is position 2 on the Water Pump plate, Engine group.
• Custom-molded shape – five holes already aligned with the cover screws: simply position and close, no trimming or adjustments needed.
• Part to be replaced at every opening – this is the component that prevents coolant leaks after servicing the impeller or the cover.
• One code for two brands – the same spare part fits Piaggio Beverly, BV, MP3, and X10, as well as the Aprilia SR GT 400.
• Inexpensive and engine-saving – reusing the old gasket is the fastest way to end up with liquid on the crankcase.

Technical specifications

Vehicle compatibility

The list is taken from the official Piaggio spare parts catalogue (B2B area). If you have any doubts, send us your scooter's chassis number and we will verify the correct code for you.

Who it is perfect for

It is intended for those opening the water pump: to replace the impeller, to redo the mechanical seal, or simply because they found traces of coolant leaking from the engine casing. It is one of those spare parts that should be ordered along with the main component, because realizing that the gasket is missing once the job has started means leaving the scooter disassembled for two days. Also useful for workshops that keep this code in stock: it covers the entire Piaggio Group 350 and 400 4V family, from the 2012 Beverly to the 2026 Aprilia SR GT 400.

Frequently asked questions

Which vehicles does the 880727 gasket fit?
In the official spare parts catalogue, the code is assigned to Piaggio Beverly and BV 350 and 400, MP3 350 and 400, X10 350, and the Aprilia SR GT 400 E5+. Exact versions, years, and markets are in the table above: we do not declare it compatible outside of those entries.

Do I have to change it if I open the pump?
Yes. The gasket is designed to be crushed between two surfaces and, once compressed, it does not regain its thickness: reusing it is the most frequent cause of leaks that reappear after a few kilometers. It is inexpensive and easy to change while the cover is already off.

Is sealant needed along with the gasket?
No, if the surfaces are clean and flat: the gasket works on its own, as intended by the manufacturer. Before installation, all residue from the old one must be removed without scratching the mating surfaces, and the screws must be tightened in a progressive, cross-pattern sequence.

Does the package include the cover?
No, it only contains the gasket. On the same catalogue plate, the water pump cover is code 1A017501, and the mounting screws are 834065 and B016775: these are separate orders. If you also need the cover, write to us and we will check the official catalogue for you.

How many are needed per repair?
One. The official catalogue plate specifies a quantity of 1 per vehicle, and it is the piece that closes the pump cover. If you are redoing the entire cooling system, check the other seals separately; they have different codes.

What should I do after installing it?
Top up the coolant, bleed the system according to the manual's procedure, and bring the engine to temperature while keeping an eye on the casing: if the gasket is installed correctly, there will be no traces of liquid, neither when cold nor hot.
