Lambretta Stepped stud, 6 to 7mm - 17x10x11mm, Lambretta crankcase side, stainless steel, MB

A stainless steel stepped 7mm to 6mm oversized stud to repair a damaged crankcase side 6mm thread.

If the thread has gone you could fit a Timesert or helicoil, these cost money, here is a simple way to repair the casing.

Drill the casing to 6.1mm and tap out the casing to 7 x 1.00mm to the correct depth then loctite and screw the stud into place.

A much cheaper stronger repair from MB.
