Which is to give the pin enough resistance to help it hold the crank assembly together in use.
This resistance means it usually takes somewhere around 4 ton's to press the standard Lambretta assembly together.
My question....
And I know it's about Vespa's so forgive me please!!!
It's a big ask, but would anyone on this forum know or have the correct figures for a small frame standard 125 vespa crankshaft assembly, both the interference fit and expected press pressures.
Anyone
