Lambretta Stainless Steel Stepped Repair Stud 8mm to 6mm - 17 x 10 x 11mm For Crankcase Side MB MBP0302
This Stainless Steel Stepped Stud can repair all the crankcase side 6mm threads that strip and pull out.
Most people don't have a Heicoil or Timesert kit (they are expensive) This is a more affordable repair. All you need is a drill, 6.5 or 7mm drill bit and a 8 x 1.25mm tap which most have or can borrow.
Drill out the hole, tap down to slightly shorter than the measurement of the 8mm end and screw in the stud by locking two 6mm nuts together, tap it a bit at a time so when its home tight the flat edge is flush with the gasket face. On final fitting use loctite.
