Collected my hybrid bellhousing today. This is to fit a Ford type Nine 5
speed gearbox onto the back of an A-series engine. The bellhousing in the car
an earlier fabricated bellhousing that the casting will replace.
I've some jobs to so on the casting including drilling and tapping 3 quarter
UNF holes for the starter motor cover (will be blanked off since the car uses
SO, what size drill do I need if I'm going to tap a quarter UNF?
Secondly, the bellhousing has a steel bracket that takes the clutch fork and
this screws into the bellhousing with a pair of metric M6 Allen caps. I'd
like to not only Loctite these 2 bolts into the casting but I'd like to
them to the pivot bolt for the clutch fork (I realise this is overkill). I
can't drill the bolt heads without a drilling jig (my jig is imperial not
metric) and Allen caps are a sod to drill anyway.
SO, I don't suppose I can just run my quarter UNF tap down the metric M6
thread and get away with it can I (I know it's shameful even to ask)?
OR anyone have a source for drilled head metric hardware - Aircraft spruce
only does imperial stuff?
