I have been researching to find out the correct bolts for mounting the gearbox to the engine on 52 star twin.
Mine has 4 bolts, (3/8W x 1 1/2") but my parts list shows 2 bolts (3/8W x 1 1/2") and 2 studs with nuts, measuring 3/8W16TPI - 3/8BSF20TPI each
I suspect that the 52/53 ST had bolts, then changed to the 2 bolts and 2 studs for the SS in 54. Is this correct??
Also if the crankcase had 2 studs, then it would be near impossible to move the gearbox out far enough to clear the studs, if the complete box was to be removed, unless of course the main shaft was taken out.
These studs are part number 35-4005 gearbox fixing stud (crankcase bottom fixing) 2 off, listed for A7, A10, and Star Twin.
This part number also listed for plunger and swing arm frame from 1954.
Any help would be greatly appreciated.
Thanks Keith
