The Piaggio 829526 is the center crankcase gasket for Piaggio LEADER 125-250 cc engines, a genuine Piaggio spare part.

Alternative OEM code: 827773.

Compatibility

Perfect for

It is intended for anyone opening the engine of a LEADER 125-250 – crankshaft, main bearings, connecting rod, oil pump – or for those with an oil leak from the crankcase mating surface. These vehicles are now twenty years old: when you reach the point of taking the engine apart, spending a few euros for a genuine gasket is the last place you should look to save money. Redoing the work due to a leak costs infinitely more than the part itself.

Frequently asked questions

What exactly is this part?
It is the center crankcase gasket, i.e., the gasket between the two halves of the engine crankcase. It seals the mating surface and keeps the oil inside.

What is the "LEADER" engine?
It is the family of 4-stroke single-cylinder engines from 125 to 250 cc from the Piaggio group, fitted between 1998 and 2008 on the Vespa ET4 and LX, Beverly, Liberty, Fly, X8, X9, Runner, Scarabeo, and many others. This is why the same part number works for so many vehicles.

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

Are other gaskets included?
No, this item is only the center crankcase gasket.

Is there an equivalent part number?
Yes: the item is also listed in the catalog as 827773.
