Just went to replace a rear bearing in a YS 91SRX and got out a YS 5860 replacement bear, installed it and all went fine until I reinstalled the fan hub. Now the motor will not freely rotate, binds very badly.

I have replaced rear bearing many times in the past but this is a first issue like this.

Are there differences in the 91 srx sold by RcJapan and one local in the states?

I see the YS Japan part list which list the rear bearing part number as S9113

I also see the YS US site, listing the rear bearing part number as YS5860

Should I get the replacement bearing from RCJapan?

Suggestions?

Sounds like the bearing somehow shifted and got cocked .......

I would re-heat the motor in the oven at 350 for about 15 min or so and try to reseat that bearing....

Been there, done that and old enough to know better.....
