4. Blinking in the daylight.

 

 Well after years in the dark its what you immagine. Meet my saviour a matched pair of Triumph  1956 6t  alternator , big bearing cranckcases. the big bearing bit is absolutly essential for this build they are far stronger. You can see a bulge just under the timing chest this signifys it as big bearing job
Now they have been exhumed a bit of prep work is in order.

A. run a drill up the threads very carefuly to get all old gasket goo and general detritus from the last 50odd years out to stop fixings "bottoming out"

B. screw a plug tap down the thread to bottom this cleans and refreshes the thread ready to take a fastening of the correct length and gets a nip on the casing as desired.
