hey all ive got a question, does the spigot bearing have to go inside the flywheel or does the fly wheel have to be removed and then put the spigot bearing into the crank

Spigot bush/bearing fits in the crank. the hole in centre of flywheel should large enough to R&R it. To remove, fill hole with grease and smack a rod in the hole. Drill it out at worst case. it locates the gearbox mainshaft (which floats a bit) in centre to with crank so clutch can stay central & flywheel must have a large enough hole so the spline on gearbox won't come in contact with it when things are all bolted up.
