Re: Endplate fixing studs

Another thought, remember clearances are very tight in this area on the Lambretta. Taller studs & nuts (I think the correct nuts are shorter than standard aren't they?) and extra washers might cause rubbing problems on the chain/crownwheel. yes steel of course ..........it was late and I was ti...

Re: Endplate fixing studs

Endplate studs are supposed to be 28mm in length with a 10mm thread on each end,by the way you dont need to fit a flat washer,just a spring washer. thats all very well but as i said 2x top sellers sold me studs that measured just 26mm and a 10mm thread has only 8mm useable thread at best. Try runni...

Re: Endplate fixing studs

Is buying a length of M7 threaded rod and cutting your own an option? Plenty on eBay. Sent from my SM-G920F using Tapatalk good idea George but probably not really a good idea for this application unfortunately.

Re: Endplate fixing studs

Sounds like you are winding the studs in till they bottom out. how did you come to that conclusion ? :) I know my post was rather long but I thought that I had made it clear that the maximum insertion was 8mm ? ;) To 'bottom out' the stud would be impossible as the threaded part of the studs is onl...
