Quoted from timlah79:
THANK YOU! I'm not worried about soldering the connectors. It's the solder "blob" on the motor housing that I do not know how to do. I also don't think it's a standard solder job. If I put my soldering iron at it's max temp 890 degrees, it doesn't even melt that stock "blob". I have even tried putting the iron on the inside of the broken stock motor housing to see if I can just pull off the blob itself. I've also tried to exacto knife it up so I can reuse it. No luck. It is not solder I don't think. It is "welded" onto the housing / w/e metal the housing is made of. I imagine even if I use the new capacitors in the same manner, that it's probably not a good idea to glue or use electrical tape to attach that housing point? Due to heat from the motor?
Temperature is only half of the equation on a soldering iron: wattage is the other. It sounds like you have a low power iron. That "blob" is very similar to how electric guitars and amplifiers have a common ground on the back of the volume potentiometer. If you don't have a local pinball repair guy, call around to music stores and ask if they do amplifier repair. Those guys will have the iron and knowhow to solder it up. Just take the old assembly and your new parts.
Below is a photo of an amp I built for a friend. I had it in for maintenance not to long ago. If you just can't find anyone, send it to me, and I'll fix you up.
