The genuine Piaggio oil sump gasket, part number B014152, seals the connection between the oil sump and the crankcase. It is used in various Piaggio four-stroke engines with displacements from 125 to 200 cc, including engines from the IGET and LEM series with air or liquid cooling. The gasket prevents engine oil from escaping at the joint between these two engine housing components.
The oil sump gasket is a separate replacement part and is particularly required when removing, replacing or reinstalling the oil sump. Its shape is specifically designed to match the corresponding Piaggio engine housing construction.
The gasket has an elongated, asymmetrical shape that follows the sealing surface between the oil sump and the crankcase. The green gasket carrier material features a reddish-brown sealing bead running along the designated sealing contour.
The sealing bead also surrounds the seven visible mounting holes. This supports sealing not only along the outer contour but also around the bolt passages.
The gasket is designed as a flat, preformed component. The mounting holes are already positioned at the required locations. During assembly, the gasket is placed between the machined mating surfaces of the oil sump and the crankcase.
In a four-stroke engine, returning engine oil collects in the lower section of the engine. The oil sump forms part of the oil reservoir. To keep the oil inside the engine housing, the connection between the oil sump and the crankcase must be reliably sealed.
The oil sump gasket performs this function at the bolted joint. Within its intended operating limits, it compensates for minor irregularities between the mating surfaces and helps maintain an even seal along the housing contour.
A damaged, compressed or incorrectly positioned gasket can cause oil leaks. For this reason, a new gasket should always be used when this engine housing joint is opened.
Gasket B014152 is assigned to the genuine Piaggio oil sump with part number B013437. Both components are listed together in the relevant Piaggio spare parts catalogues within the engine lubrication system assembly.
The gasket is used in different engine variants, including selected air-cooled AC engines and liquid-cooled LC engines from the Piaggio IGET and LEM series.
The exact application depends on the specific engine version. Even within the same model range, different gaskets may be used depending on the year of manufacture and engine code.
The vehicle list covers different model years and engine versions. Compatibility depends on whether the genuine Piaggio oil sump gasket B014152 is specified for the particular engine. Before ordering, the engine code and original part number must be checked against the appropriate spare parts catalogue.
Before installation, the sealing surfaces of the oil sump and crankcase must be thoroughly cleaned to remove old gasket residue, oil deposits and dirt. The mating surfaces should be inspected for damage and distortion.
The new gasket must be aligned according to its contour and the existing mounting holes. It must lie flat and must not slip out of position or become trapped when fitting the oil sump.
The mounting bolts must be tightened according to the vehicle manufacturer's specifications, following the prescribed sequence and using the specified tightening torque. Additional sealants should only be used if expressly required by the relevant repair manual.
After installation, the engine oil level and the tightness of the joint must be checked. A previously used, damaged or deformed gasket should not be reinstalled.
The genuine Piaggio oil sump gasket B014152 allows the sealing joint between the oil sump and crankcase to be correctly renewed on the specified engines. Its precisely defined contour and integrated sealing bead enable the existing gasket to be replaced in accordance with the original engine construction.
