Standard clutch spigot bush (24mm) to suit hydraulic clutch 105 series twin cam engines. Also fits Montreal engines.
Some early 1750 engines uses the earlier bush - sold under code EN101.
** NOTE ** - If you are having a later crank (75 twin spark or Alfetta) machined to take a spigot bush so the 105 gearbox will fit you need to tell the machine shop to drill the hole at least 30mm deep even though the bush only sits 22mm into the hole. This gives the necessary clearance for the gearbox input shaft. If you don't machine the crank deeply enough the gearbox will not bolt up!
