Title: rear wheel assembly RD400C
Post by: Membername on June 28, 2019, 03:58:03 PM
Getting ready to drop in the rear wheel bearings (RD400C), is this the correct assembly?  The parts fiche shows the collar that goes into the sprocket side bearing as being on the sprocket side of the bearing rather than on the spacer side, but my bike (one owner, my uncle) had the collar on the inside of the wheel next to the spacer.  I think the bike was prolly correct since that page of the parts fiche has several other errors, including showing the axle in the wrong direction.  Can anyone confirm that the picture is correct, including the position of the collar on the sprocket side bearing and the orientation of the spacer between the two bearings? 

Thanks,
Karen

It can all go together one way. If I remember correctly, the diameter on the sprocket side ( drive side) bearing is bigger than the caliper side. The collar and spacer go on the side with the bigger diameter. Without that spacer, that bearing is going to be sloppy on the axle.

There are several errors in that diagram, another is the order in which the hardware goes on that bolts the caliper bracket to the wheel assembly. The caliper bracket is shown backward. The castle nut should go in the caliper side. Then the nut and large bolt that mounts the caliper bracket goes on under that. The large nut that actually bolts the bracket on faces outward to the right side of the bike.

Here's a photo of how the caliper side should look.(https://uploads.tapatalk-cdn.com/20190628/cd20929cfa79daad29bd61a62cd7271c.jpg)

Pic is correct. The pressed in spacer in the sprocket side bearing does face the inside.
