Electric motor reassembly
| Maurice | 15/06/2018 16:52:45 |
| 469 forum posts 50 photos | I have just dismantled the motor from my lathe to clean it out, as I thought a piece of swarf may have entered the casing. There are enough slots and openings! As I removed the cover with the start switch on it, two wavy spring washers about 1 1/2" diameter fell out. There are none the other end. The housings look identical, as are the bearings. One at each end makes more sense to me. Has my motor been wrongly assembled for all these years please? Maurice |

| 978 forum posts 26 photos | It is probably correct. One bearing housing should be a tighter fit, whilst the other allows some axial movement to handle thermal expansion - the wavy washers will go in the 'floating' housing.

| 1394 forum posts 103 photos | The wave washers are to provide a small axial preload on the bearings to ensure that they roll & don't skid if the motor is run unloaded. I would put them back as they were, as they were most likely positioned as the maker intended. Nigel B |
