JT B4007 Transmission Belt for Piaggio

The JT B4007 drive belt is an essential component for the proper functioning of your Piaggio scooter. Designed to ensure smooth and reliable power transmission, this belt is manufactured with the technical specifications necessary for optimal vehicle performance.

It is important to note that, due to various measurement and production processes, length specifications may vary among different manufacturers of trapezoidal belts. However, these differences do not compromise the functionality of the belt. The measurements are determined according to industry standards that consider the external length (Le), internal length (Li), and pitch length, the latter defined at about 3/4 of the height of the belt according to the DIN 2215 standard.

To ensure accurate measurement, it is crucial to also consider the belt tension specified by the vehicle manufacturer, as this factor affects the production process. It is advisable to refer exclusively to vehicle assignments to identify the correct belt.

Particular attention should be paid to the oil pump belt, especially after a breakage of the trapezoidal belt. The flying parts of a broken belt can damage or destroy the oil pump belt, which is located behind the variomatic and is not immediately visible. Checking its condition is essential, as a damaged oil pump belt can cause piston seizure, seriously compromising engine performance. Make sure to keep your scooter in perfect condition with the JT B4007 drive belt.
