Good evening one and all!
This is my first post, so I suppose the decent thing to do would be to introduce myself prior to tapping your collective minds for knowledge and information. My name is Aleks, I'm living in Canada and according to my girlfriend, my romantic notions of getting my "pieces-in-boxes" 1972 Commando 750 running someday are, if not somewhat entertaining, then outright folly. However, I refuse to lay down. So does the Commando, apparently (see images).
Onto the meat of the matter then. Attached you will find images of my first roadblock. The infamous sump plug/monster nut. Unfortunately, its non-uniform shape makes it difficult to measure. The closest size seems to be either 37mm or 38mm. I have a SAE 3/4" drive 1-1/2" shallow socket which seems to be too big (?!) - there is far too much play, whether owing to the deformed nut or something else, I'm not sure. I sourced a poorly crafted specialty tool for removing the plug off eBay, but it too seems to have far too much play to do any good. Likewise, given how stuck the nut is, I'd need to weld the tool onto a pipe of some sort, to get any real torque.
I was just wondering, based on what you're seeing here, what the best plan of attack would be? The chisel-like mark you see was made by a previous loving owner(s), who may have fastened it, in what seems to be a "once and for all" sort of manner. I've been applying some deep penetrating lube and will hit it with a heat gun once I've sourced the appropriate socket. If a breaker bar doesn't do it, would you advise me against trying an impact wrench? What about tapping it? Unfortunately, I'm having a hard time finding images of the plugs, but instinct tells me, they'd be too shallow to tap. What are my options here?
Worth noting (maybe): I may have a franken-Commando on my hands. It's registered as a '72, and the case is stamped 20M3S/142663, yet on another part of the bottom-end I also saw 206429. The frame, sadly, did not have the little riveted plate denoting the frame number.
Thank you all in advance for taking the time to read my mini-rant - any pointers or advice you can share will be a huge bonus.
Sincerely,
Aleks
