Feeler Gauge SIP spacer gear box

Most maintenance on the motor of your Vespa requires the use of special tools and adapters. Without their use a quick and professional service without permanently damaging engine components is virtually impossible. Regrettably, many of these exclusively Vespa devices are no longer in production or indeed available, apart from a few parts of dubious quality and origin.

Hardly anything can be as annoying, while working on your Vespa, than poor quality tools. For this reason we have had the complete range reproduced and also in some cases even redesigned. Our SIP tools and adapters are precisely manufactured using the highest quality, genuine tooling grade steel, with some items also being surface treated for extra durability

The SIP feeler gauge allows exact measurement of side clearance. Should there be too much clearance, thicker spacer discs are needed, otherwise shifting will be too imprecise and can´t hold the gear. Installation play should be between 0,15 and 0,40 mm (race engines need 0,05 - 0,10 mm only), removal play maximum 0,50 mm.
