The harebrained idea was mine, its above the dynamo chain, just to squirt chain lube now and then, not to check tension.
ok, to quote GB possibly misquoting John Swigert: 'Okay, Houston, we've had a problem here.' ....

stev, I'm so glad you pointed that out...All the times I've used that phrase, I seriously never gave a thought to how the hair would actually grow brains

...would be kinda tickly, and also never gave a thought that the humble Br'er Hare would be held in such esteem as to have these (or any other) hair/hare-brained ideas... .... kinda reminds me of 'Big-Bunny', The Goodies episode....how'm I doin'

?......(that's the serious fun bit)
...but on another note,
like it was a hole ...........or some other hair-brained idea....
, is where I must've had like a dyslexic moment and it should've been "some hair-brained *other* idea".; totally different.........Sorry to cause you distress...

So now I'll give my own Leporidae/leporid-brained idea... I did an oil change the other day, and when I pulled off the outer timing case, there was evidence of water- just a bit, and as we don't have lot of wet-stuff from the sky (although it did while I was at work the other day), maybe from the quick HP water blast I gave it immediately beforehand, but as there was also milky goo on top of the oil pump, and a film of oil in the belt-drive case, it made me wonder if BG's 'Tiny Screw', may have been intended as a condensation release...

As far as the lifting-eye concept goes, it would need another one in parallel, as they have a tendency to undo if hoisted with a single line....so get screwing BG....

In fact I have a couple of eye bolts installed on mine.....
