Piaggio 872909 Engine Crankcase Gasket 0.4 mm – Beverly, MP3, X9, X10, Nexus, Fuoco 400/500

The Piaggio 872909 is the 0.4 mm thick crankcase gasket, an original Piaggio spare part. It is the gasket that seals the joint between the two crankcases of the Piaggio Group's 400-500 single-cylinder engine: it should be replaced every time the engine is opened. The official catalog name is "Guarnizione semicarter" – half crankcase gasket. It fits Beverly 400/500, MP3 400/500/530, X8 400, X9 500, X10 500, X Evo 400, Gilera Nexus 500 and Fuoco 500, Aprilia Atlantic and Scarabeo 400-500.

✓ Strengths

• Original Piaggio spare part – code 872909: die-cutting, thickness and material are as per design specifications
• Declared thickness 0.4 mm – on crankcases, thickness determines internal clearances: it's not an aesthetic detail
• Mandatory at every engine opening – a reused gasket is the #1 cause of oil leaks from the crankcase mating surface
• Covers the entire 400-500 family – from 2001 to today's MP3 530 HPEs: four brands, over thirty versions
• It costs little compared to the engine opening work it necessitates

Recommended products

• Crankshaft oil seals – always replaced along with the crankcases
• Cylinder head gasket and valve cover gasket – if the engine is open, it's worth replacing them
• Complete engine gasket kit – often more convenient than individual parts: ask us for the code for your model
• Engine oil and filter – after such an intervention, you start from scratch

Who it's perfect for

It is useful for those who are doing an engine overhaul – crankshaft, main bearings, connecting rod, oil pump – on a Piaggio Group 400-500, and for those who have an oil leak from the crankcase mating surface. This is not a part you buy out of curiosity: you buy it because the engine is already on the workbench. At that moment, installing the original part with the correct thickness is the only sensible choice: redoing the job for a wrong gasket costs infinitely more than the part itself.

Frequently Asked Questions

What exactly is this part?
It is the gasket between the two crankcases of the engine, 0.4 mm thick. It seals the crankcase mating surface and keeps the oil inside.

Is the thickness important?
Yes, very: on crankcases, the gasket thickness influences internal clearances. Install the one specified for your engine.

Can I reuse the old one?
No. It is a single-use component: it deforms upon first closing, and reusing it will cause oil leaks.

Are other gaskets included?
No, this item is only the crankcase gasket. If you need the complete kit, please ask us.

Will it fit my scooter?
It covers virtually all 400-500 group engines from 2001 to today, including MP3 530 HPE. Check the table and, if in doubt, send us your VIN.
