Transmission Drive Jt Belt Standard Alternative 7550403 for Motorbikes

Description

Different measurement and production methods used by V-belt manufacturers result in different length specifications across manufacturers.

However, these differences do not affect the functionality of the belts.

Different industry standards mean that different parameters are used to determine the length specifications.

A distinction is made between external length (Le for short), internal length (Li for short) and pitch length.

The pitch length describes the length measurement at approx. 3/4 height of the belt according to DIN 2215.

Furthermore, the belt tension specified by the vehicle manufacturer must also be taken into account for reliable length measurement, as this is also an important factor in the production process.

Due to these different measuring methods, different V-belt dimensions from different manufacturers can occur on one and the same vehicle.

Please orientate yourself exclusively on our vehicle assignments.

Especially for Piaggioscooters, special attention should be paid to the oil pump belt after a broken V-belt!

Due to flying parts of a broken V-belt in the engine housing, the oil pump belt may have been damaged or completely destroyed.

Since it sits behind the variomatic and is not immediately visible, it is always worth taking a look behind the variomatic to check the condition of the oil pump belt and replace it if necessary. A damaged or destroyed oil pump belt leads to piston seizure!
