Hi all. So, starter motor died on me today. Very suddenly without warning. No ticks, clicks, whirring or otherwise. Nothing...at all!! Hitting it with a hammer made it click a couple of times but soon after there was nothing again. I have a used one on the way but how on earth do you take the buggers out? Is it hex bolts? I’ve got 2 hex sets and on both of them, they are 1 size too small and the next size up is too big. Losing the will to live. Thanks in advance.
