Constabulary Report post Posted January 9, 2016 (edited) My opinion - it is not worth the work / the trouble / the time / the money. Better buy a new JACK Servo Motor from College Sewing in the UK (if you don´t need the bells and whistles your EFKA has) or one of the HoHsing motors some members have recommended. Same with your very old Simanco Motor, I would not repair it except you like the historical motors but be aware - they are decades old and probably not electrically safe anymore.

TinkerTailor Report post Posted January 10, 2016 (edited) It might just be dust in the fan or a bit of lube needed. Rip it open, clean and lube it and put it back together. That was an expensive well built motor. You pay for good things so they are built to last and service. I think it is well worth trying, Lube is cheap and easy. The bearings are likely replaceable from places like mcmaster-carr. I looked up a few parts lists for other efka motors and they list what appear to be standard bearing sizes. However do keep in mind if it starts to go south, or major parts are needed, draw the line and bin it. (edit: it is a 6303ZZ bearing used on all the motors i found breakdowns for.)

Its not that hard to run a new 3 wire grounded cord and ground the metal case of the motor. Edited January 10, 2016 by TinkerTailor Quote Share this post Link to post Share on other sites
TinkerTailor Report post Posted January 10, 2016 (edited) What is the model number on the motor? Here is the parts breakdowns for a few similar motors, if not the same. http://www.efka.net/en/Produkte/ersatzteile-EN-FKV-motor.htm they also use 6302ZZ. and 6001.2ZR, also readily available. The 6303 and 6302 are 5 bux each in canada. Edited January 10, 2016 by TinkerTailor Quote Share this post Link to post Share on other sites
Davidstryingtosew Report post Posted January 26, 2016 +1 Tinker Motors are so simple. The only real wear is in the bearings. If you plan to have it down for a few days, definately order some new bearings, dont even bother with lube. Like Tinker says, there just $5 each off Ebay. you might need to have a shop press the old bearing out. The new ones can be tapped in with a hammer. But use a block of wood (like a 2 by 4) between the bearing and your hammer. Just light taps, not one big hit. It'll get in there. Then you'll have a new motor ready for more decades of service.
