I bought this for £150 earlier this year on ebay. It had come from a CCM that the owner got back 3 years after it was stolen! It had been partially stripped by the 'perps' and left in an ugly mess. The seller confirmed it still turned over. WIth it came the CDi, coil and carb. In that condition it was a punt, but I always like a gamble...Here is how it looked at first:











I started to clean it up:



Then gave it over to Minter to look at...

Our main man Simon has entrusted me to rebuild a 640 which he happened to stumble upon!

Its been attacked by rust as the clutch case was off it for probably ages.. its rusted the Main Bearings hence a need for a bit of a rebuild..



A bit of heat manged to get half a sprag and rusted on primary gears off..



Found some crude oil in the filter housing!



Then came the big split..



All is well inside, apart from main bearing!



Anyone got a crank pushing tool?...



The offending article now removed - proper lumpy!

Its amazing what you can do with all the correct tools and an oven!





Now for the hard bit..... putting it all back together!!

Fantastic job mate.
I would get it all back together then find a spare cog.

I would love to have the knowledge, patience and time to be able to do that.
looks great.

Very impressive indeed. Really well done.

Looks like a fun job. I must get me one of them engine stands. I bet Simon can't wait to get it fitted to his bike.
Good luck with it.

I think Garys a plumber in his spare time nice work keep the pictures coming

I can't remember, it was titled "breaking CCM" and he described it as a 636.
