Cruciform PIAGGIO

PX (old)4
type
Product description
The gear selector cruciform has one of the toughest jobs in the whole gear box. The gear selector cruciform is put in position within the desired gear cog on the output shaft every time you change gear and ensures that the power of the motor can be effectively transmitted through the desired gear, to the output shaft, and finally the rear wheel. The intervals at which the cruciform should be replaced are determined by the mileage of the motor. The life of an average cruciform is usually over after 10-12000 km or 6-7500 miles. Broken or incorrect selector boxes or rods, wrongly assembled output shaft assemblies, forgotten safety washers for the old PX cruciform or badly adjusted gear cables all shorten the life of an average cruciform quite drastically. This leads to the gears not staying in position and in a worst case scenario create much more extensive damage within your motor. For this reason the cruciform should be replaced during every major service of your motor. We recommend the use of original PIAGGIO cruciforms. If you are riding on a tight budget you can also make use of the aftermarket items. If you are riding a tuned PX EFL VESPA model the use of a MJ9 Hard+ cruciform has proved successful. Exact dimensions and a harder production material than the standard items make these cruciforms especially suited to the job in hand. Extremely durable cruciforms with a minimal increase in were to the output shaft cogs are the more than welcome effects of this timely update. The division of the models into a first and second series is only to enable a difference in the groups of articles. Exact model listings explaining which cruciform is relevant to which model can be found at the bottom of the page.
Conclusion:
You cannot afford to save on this essential spare part. One should always be included in every toolbox. -TIP: Always check that you assemble the gear cogs correctly arranged and in the right order . Do not forget to measure the end float to be sure of the correct tolerances for your output shaft assembly. Check the cruciform and selector box for wear and always use fresh gear box oil!
