I finally got tired of tripping over the Cinel 202-12 that I've had holding down a corner of the shop for too long and decided to try and get it running - I posted some questions 5 years ago but time flies.
when I tried to power this up 5 years ago it made horrible noise and the driven pulley seemed to be low on the shaft. I bought the machine out of a school, not under power. The drive belt appears new. On tearing into it today I'm thinking someone did a belt replacement and screwed it up more than fixed it.
Pulled the motor housing / drive off the machine, pictures below. Here are my questions - figured I would ask before I do something stupid and break something.
Does anyone have any tricks for removing the spring on the motor side? I'm assuming I have to work the belt off - which should be a lot of fun. Then put a bit of compression on the spring so as to remove the snap ring, release pressure and pull things apart. Anyone have any wisdom on this?
Likewise, anything to watch out for when removing the pulley assembly that is on the quill side? You will note there is one extra piece that was between the bottom pulley sheave and the motor housing base - it was captured by the drawbar but just floating. I'm suspicious that it is the retainer - part 85B in the parts list - and whoever had it apart put the whole thing back together incorrectly. As one bolt was missing and a large internal tooth lock washer was also floating around in the housing I'm figuring it was not the best person working on it. To top it off there was no woodruff key to drive the quill. Keyway in the number 98B helical gear was full of crud - looks like the key got lost at assembly time.
The quill power feed does not appear to engage, the handwheel just spins. I think at one point on here I found a post by someone who had repaired the same problem, what amounted to a shear pin in the mechanism. But now I can't find that thread. The power feed box will also not hold oil and I think that was covered in the same thread.
I have not had this thing running - but, since I have it this far apart would you think I should open up the back gear cavity and check things out, and re-lube? Machine is a 1966 and in pretty good shape overall. As I said, came out of a school. It's been banged some but not really worn.
Thanks for any advice you might have on attacking this. I've searched and not a lot out there on actually tearing into these variable speed drives.
