400-4 Frame - Am I Missing a Bit?
« on: June 03, 2014, 03:11:07 PM »
Hi experts,

Another question from Mr. Amateur coming at ya...

Can anyone tell (show) me what this apparently missing part of my frame is for (CB400-4 1976), please?

Thank you,

Drew

I think it is the small plate the rectifier bolts to. As the frame isstripped itshouln't be to difficult to get one made and welded on.

Ah, seems I need to get my friendly recitfier to rectify this for my rectifier!

So the obvious next question... anyone got a picture of what the rectifier bracket looks like so that I can create one, please?

Thank you again, experts out there!

Here ya go... noting that its 'jaws' are open to 'slide' the rectifier bolt in/ out as I remember...

Ah... just found an old pic before the bike was restored... you can just make out here the cut-out for the rectifier mounting bolt.

Note that the mounting bolt (& lug) has a flat .... to stop the rectifier twisting.

Cheers,
Simon
