A quick nerdy update to keep us all entertained  :) As long as the parts can print with fine enough detail, this is going to work like a charm, and we will be able to rescue a lot of 'bad' Mac floppy drives/motors.  I heard from a few of you, that not only the smaller gear gets damaged over...

Yessir. I print at Shapeways.com

I have generated precise CAD for all four gears of the floppy drive. I am currently printing them in fine detail, and will be testing as soon as they arrive. I would let you all know if this works out the way I expected to.

Been searching for over an hour... I cannot find any proper instructions on the procedure to remove Analog board for re-capping. (mac %12Ke, specifically, or any similar compact Mac).    I figure I have to discharge CRT first, but then wonder about what steps need to be taken to safely handle...

Diameter of the large gear is 9.4mm. Believe me, I looked all over the Internet and found several places selling these, but nothing in the exact size.

Do you all recommend full crt and large capacitor discharge prior to replacing these small caps?

Solidworks for cad. Shapeways for printing.

The new gear is on the far right. It is a compound gear, so it has a small gear at the top and the larger gear at the base. The one at the top is making proper contact. The one of the bottom is completely missing the master motor gear driver which you can see is not moving. It is the small...

So I just realized that I selected the worst possible material to print that part!. They do have an ultra fine detail option which I will be testing next. I have high hopes that it will work I will post progress soon!

Thanks.

uni: I don't really know what the difference would be between the paper and the poly ones.  If anyone knows the correct type, please chime in!

Uni:  Hrmmm...  so those you posted are Metallized Polypropylene Film.   The ones I posted are Metallized Paper Film.   I think the original ones are paper, no? The price for the same part (all else equal) is about the same on both places.  I think Digikey ships cheaper to me that's all...

Strange.  I just double checked and they work fine for me  :( Search digikey.com for parts: PME271YA4470MR30 PME271M647KR30

Ok, I think these are the best replacements.  What do you think uni? http://www.digikey.com/scripts/DkSearch/dksus.dll?Detail&itemSeq=162607639&uq=635536740540146454&CSRT=6333285681771440465...

Where do you guys recommend shopping for capacitors...?  From my international board, it looks like I will need a 0.47uF X-type polypropylene metalized capacitor. (C37) Also while at it it looks like C33 and C36 are smaller, but same type, and would be wise to replace... those are Y-type ...

Do you have a spare You want to get rid of? :)

Okay I see. I'm going to replace it. I assume it is C 37 in my international board. Attached is a picture, I think I see a crack. Most replacement guide to say to use a Y spec capacitor. This one is labeled as X spec however.

I had finally gotten my old Mac 512Ke together after a mildly successful floppy reapir, and after about 1 hour of use it started going crackle crackle and then a whole lot of DENSE NASTY SMELLING WHITE SMOKE... woah!  I pulled the plug immediately. opened her up, and cant seem to find any...
