Hi All,
So I lost some ball bearings to the armature of a 622-100X motor and I want to replace them. My question is can I just use the bearings pressed in the washer or do I need to get the exact replacement with all of the individual balls.
Thanks for your help. Bob

The 622-100X used before 1950 uses separate washers and balls 671M-19 & 671M-21 where as the later 622-100 used the 681-121 and 671M-23.
You need to get the individual balls unless you want to redesign the bearing arrangement in the motor. The caged balls are not a direct replacement. If you give Jeff Kane, The Train Tender a call, you will have the correct replacement parts in a couple of days. I grease up the washers and then use a little of grease on a tooth pick to put the balls in. Just make sure you do not have too much end play or the balls can get out and will be losses. If there is to much end play, over 0.010", add an additional 671M-19 thrust washer to the stack.
I'll just get the direct replacement 671M-21. Thanks for the help!
