Well after almost 28 years of CB750 ownership, I had still not discovered a suitable tool for removing the really stubborn ones, even my special "Metrinch" sockets and spanners (Simply the best tools in the world, and more surprisingly, they're English!) would rip ther corners offa them.
Out of sheer desperation, I pulled out the most useless (until now) tool I've ever been given, the "Supa Spanner", a "fad" tool "As seen on TV" about 25 years ago, and always demonstrated on a hinge bolt on a farm gate-post, because due to it's design, it wouldn't fit anywhere else.
How the "Supa Spanner" works, is it has two ends with a weird sort of "diamond-hex" hole at either end, that is hinged off the tools handle. To tighten or loosen, you put the hex hole thingie over the hex head of the bolt, or nut, then bear on it with the "Cam" shaped on either end of the handle, and bugger me, it worked perfectly! Now this is on a CB750k2 that, judging by the "fur" on the alloy and the rusty running gear, has seen more than it's fair share of wet weather, probably leaning up against a farm shed for the last few years.
I got so "cocky" that I removed the oil gallery plug so as to fit an oil pressure gauge, just to make sure the oil pump is still alive? The "Supa Spanner" worked perfectly for these tasks. I doubt if there'd be any for sale nowadays (although I haven't checked Ebay yet) but just about every male Aussie would have one in the bottom of his toolkit, as they were cheap "stocking stuffers" and i'm sure I was given at least two, although I can't find the second one, so maybe I "re-gifted" it the following christmas, ha ha! Okay, here's a couple of pics, ooh, and also, when you refit them (if you don't buy a set of kevin's beautiful CNC replacements, I've got a set and they are magnificent!) put a dab of anti-sieze compound on them, oil won't obviously do much as they're pretty much awash with oil with normal use? Cheers, Terry.
