Default C-clip and washer set installation

I purchased an Xnova 4530 motor used here on HF. I took the motor apart for cleaning and maintenance. I noticed that some of the washers are missing. I ordered a set of washers from Amain. I have not found an installation diagram. What is the proper order of installation of these washers to include the wavy washer?

hey john, I usually put one brass one at the bottom of the shaft, in the can then install the stator, I think that's what its called.. then, if they fit. a flat, then the wavy, then the clip.. but I don't think you can go wrong as long as there is a washer on the shaft first.
ive had motors make weird noises and grinding when turning by hand.. turned out there was no washer on the shaft first.
hope that helped.

This was Kyle's response:


The wavy washer goes against motor, brass washers go on top of that. The amount of brass washers depend on the play once the "C-clip" is back on, you might need all of them or you might not.

Kind of a related question...

Some motors I dismantle for repair have a brass washer between the lower bearing and the can. Some do not.

Should they all have one? It seems like the bearing inner race should not abut the can.

Thanks
Dave

I adjust the play of the can, once the c-clip is installed, by pushing the shaft in or out more with an arbor press.
the wavy washer takes up that play, but ive run them without them and haven't noticed anything abormal.

This is Xnova's response:


Normally , the first, put spring washer into, then 0.5mm washer and 0.2mm washer , then C-clip

then you hand spin and press motor rotor to check ok or not, if still a little loose, then put another 0.2mm washer in .

I also asked Xnova about inserting a shim inside of the motor can before inserting the stator. This is the response:


not need .

the shim stack depends on the depth of the shaft and how far it is put in the can.. it varies from motor to motor from what ive seen..
but great info john. very useful, thanks so much.
