Thought I'd start a thread so that I can show you this motor I'm about to resurrect .... and some of the general CX stuff that doesn't go into build threads.
This motor
came as spare when I bought my 500C about 11 years ago. It's been sitting on a shelf ever since. It is a 78 block, which has the same 2045 first four digits of the engine number like every other 78 block or frame have here regardless of source. {I have parts from several different job lots}
Anyhow .... though the crank turns smoothly and there is no evidence of bearing failure I'm hoping that the crank and bearings are good as this is to be a cheapskate build, replacing only those things that really need it - and replacing all of the missing parts from the parts stash.
It will get new rings and chains, but likely good used OEM tensioner parts.Unfortunately, it came with my 500C. I say unfortunately because this individual was a ....... mechanical ...... butcher .... This motor shows evidence of his attempts to something something or something else this motor. My 500C had many horrors when purchased and I couldn't believe he'd actually been riding it.
Anyhow, the first thing I noticed when cleanup started was this.
Why would anyone do this much damage? Presumably just to remove a collar .... with a cold chisel. And mangled the O ring face. I can fix that, with a dremel, JB weld and maybe a thicker O ring.
Moving on, I then found this
How does that happen? Subhuman intervention? I'll look at it when I pull it off tomorrow and make a judgement call whether it's usable. If not, I have another and I've a 50/50 chance it has the same sized bearing hole so I can transfer the bearing. I do have bearings, but I'm as tight as the fishes proverbial with them.
Pulled the gearbox and am dismantling, cleaning and checking it now.
And .... back to that. I note it's not cleaning itself.
