Crankcase Dowel Stud (M6×75, Bottom Joint) for Royal Enfield Bullet/Electra/Lightning | 111864/B | Genuine OEM

If you’re rebuilding a retired-model Royal Enfield engine, this Genuine OEM Crankcase Dowel Stud (Small) – Part No. 111864/B is the correct fastener used in the crankcase bottom joint (dowelled type) to maintain accurate crankcase alignment and reliable sealing. In practical terms, a worn, bent, or incorrect stud here can cause improper case mating, repeated oil seepage, and premature gasket failure—especially after an engine overhaul.

This stud is commonly referenced as a “Stud, Dowel (Small)” in the retired models parts catalogue and corresponds to the dowelled crankcase stud specification used by specialist dealers (commonly listed as M6 × 75mm, dowelled type) 

Why OEM matters: aftermarket studs often vary in thread accuracy and shank tolerances, which directly impacts crankcase alignment. With genuine fitment, you reduce rework risk and improve long-term reliability after assembly.
