Not sure if this is the correct forum to asking such a question, but I am tearing down an old AC motor that has seen better days. Essentially through to clean each component and replaced any frayed wiring. I cleaned up shaft housing and noticed a piece of cotton hanging out quite a bit (now know its the oil wick to lubricate the shaft) so I tried to pull grab and pull it out, but a little more came out from the recess. I figured I'd better consult someone before I get ahead of myself.

To give an idea of what I'm referring to check the image located quarter ways down the page and note 'e' in Figure 1. http://wiki.vintagemachinery.org/Electric-Motor-Tutorial.ashx

Is it possible to replace this wick?

  • Are you asking can it be removed and replaced(the answer is yes) or how to remove it as it is falling apart while being removed? – mikes Sep 11 '15 at 20:54
  • I think at this point it is going to need to be removed and replaced otherwise it will interfere with the shaft. How would I going about replacing it? – wellington Sep 11 '15 at 23:35
  • I assume it uses sleeve bearings? – Pubby Sep 12 '15 at 22:20

I havent done one in years , not really hard if the sleeve is not two badly worn, pull the bolts that hold the end bells and slip the end that is falling apart off, examine the sleeve if it is worn you will need to get a shaft measurement and the outside diameter and replace it the ones I remember doing had wool packing but you said this was cotton, .there are 2 types some have an end plate (the easy ones) pull the plate fill with material and put the plate back on, saturate with oil and reassemble the end bell on the shaft and tighten the bolts, the tough type ,. same start remove the end bell Carefully press out the end cap seal so you can re use it once that is out you can press the sleeve out to the center, use caution this is very poris and may be brittle if it overheated, if in good shape repack the "void" and as you get close to full slip the sleeve back in 50% then continue packing untill no more will fit, it helps to oil the material prior to pressing the sleeve all the way back in because once it is damp it stays in place better once you have the sleve back in replace the end cap seal, saturate with oil , replace end bell and bolts and you should be good to go

    I think it probably is really wool: all the best motors used that. It probably is not cotton. – wallyk Nov 25 '15 at 0:06
