z400d3 Posted February 3, 2021 Report Share Posted February 3, 2021 I have a question around the orientation of the spacer that fits between the bearings The spacer has a shoulder on one side and I keep seeing mention of it being important that it's installed the correct way around but no mention as to which way is the correct way The manual doesn't show a shoulder at all so not much help there and I've been searching the web but no luck with a conclusive find On the exellent "My Ural" site there is a picture that appears to show the shoulder nearest the threaded part of the spindle prior to insallation http://myural.com/Wheel Bearing Service or Replacement 033_small.jpg When I stripped my wheel down the shoulder was facing the opposite way One wheel bearing was collapsed so of course that could be why ? Any help clarifying the orientation of the spacer would be appreciated Quote Link to comment Share on other sites More sharing options...
z400d3 Posted February 3, 2021 Author Report Share Posted February 3, 2021 I have also seen a You Tube video showing it this way around https://www.youtube.com/watch?v=SSQif7ueUvo&t=119s Quote Link to comment Share on other sites More sharing options...

Scott E Posted February 6, 2021 Report Share Posted February 6, 2021 All that separation flange with it's mounting shoulder does is keep grease from migrating freely from one bearing to the other so one both have a roughly equal amount of grease. I can't see where placing it in one direction or the other would make any difference. It's just a pressed on fit on the bearing spacer. After I acquired my my Dnepr MT-11 I took all 4 wheel hub bearing assembly’s out to clean and repack them. They had never been apart from the factory. 2 hubs had the separator flange shoulders pointed in one direction and the other two the opposite direction. All four were very lacking in the amount of grease on each bearing. It was obvious whoever assembled them put a single finger in the grease tub and wiped it on the outside of the bearings and called it good enough. No packing grease through the roller pins and cages at all. The Ural hubs are exactly the same internally as Dnepr hubs and parts are interchangeable using common bearings and hardware between them.

z400d3 Posted February 6, 2021 Author Report Share Posted February 6, 2021 Thanks Scott I had the same thoughts myself, couldn't think of a reason why one way around was better than another but thought it best to ask the experts 🙂 Quote Link to comment Share on other sites More sharing options...
Serious Black Posted February 6, 2021 Report Share Posted February 6, 2021 It makes no difference which way round the spacer is. Quote Link to comment Share on other sites More sharing options...
z400d3 Posted February 14, 2021 Author Report Share Posted February 14, 2021 Thanks for the responses ... much appreciated It does appear that the spacer can go either way around During my research I came accross some instructive videos on Youtube ... https://www.youtube.com/watch?v=ZVgDG3oA04s https://www.youtube.com/watch?v=zINkpA6vcEA This one gives a detailed description of the orientation of the various parts at about 4 minutes and 25 seconds in https://www.youtube.com/watch?v=K7ukRQiE904 The audio is Russian but you can enable "ropey" subtitles in english by using this method ... On the lower bar on the right hand side of the Youtube video 1. Click on "subtitles/closed captions" to turn on subtitles 2. Then click on the "settings" icon to the right of the "subtitles/closed captions" and click on "subtitles/cc" 3. Click on "Autotranslate" 4. Click on the language you wish to translate to Quote Link to comment Share on other sites More sharing options...
z400d3 Posted February 19, 2021 Author Report Share Posted February 19, 2021 A visual explanation that confirms the orientation of the spacer makes no difference at all as it's just a spacer with a dividng washer ,the collar I could see was was just the fold ...

z400d3 Posted February 19, 2021 Author Report Share Posted February 19, 2021 I was looking for something that would make installing the bearing races a little easier and provide less risk of damaging them, I came up with this ...... I bought a 33mm deep reach impact socket from ebay and worked the side wall thickness down on the belt sander until it would slide nicely into the hub https://www.ebay.co.uk/itm/1-2-Drive-33mm-DEEP-IMPACT-SOCKET-12-Point-Bi-Hex-Design-by-NEILSEN-TOOLS/253241034169?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2057872.m2749.l2649 Works a treat ....
