Castle Nut Tool SIP for castle

nut bearing drive shaft

/GL/Sprint 1°/V 1°/180 Rally

castle nut for Vespa 160 GS
/180 SS
Ø 46,9 mm, 8/9 pins, 2.8mm

Used to open and close the drive shafts castle nuts at oldie engines.

The SIP castle nut tool is used to open and close the drive shaft castle nuts of vintage Vespa models. In the course of time castle nuts with different notch layouts have been used. For that reason we designed the SIP castle nut tool in a way that it will simultaneously open/close castle nuts with different sets of notches. The tool for the 160 GS/180 SS is thus suitable for castle nuts with a distance of either 3mm or 5mm between their 9 notches. The tool for the 125 VNA/VNB will open and close castle nuts with either 8 or 9 notches. While both ends of the tool are equipped with cogs that will engage in the notches of the castle nut, it is - thanks to a square middle part - easily operated with a standard 1/2" wrench. Attention "left thread", don`t use a wheel gun!
Result: Useful tool for the restoration of older Vespa models and an asset for any workshop.


Sip Tip: Make sure the cogs of the castle nut are intact. Should they be worn, use a new castle nut (depending on the model) part no. 25276300 (GS), or part no. 2110415/2110412 (VNA/VNB).
