John76 Posted October 5, 2022 Share Posted October 5, 2022 Time for the front wheel bearing cleaning, packing and adjusting maintenance. Noticed the washer behind the castle nut has a flat side and a curved side on the small key tab. I never noticed this during prior servicing. That was years ago, and I didn't have the luxury of time to notice such details. Do you install the washer flat side in (against the bearing) or curved side in? Or does it matter??

TobyB Posted October 5, 2022 Share Posted October 5, 2022 It really doesn't matter. The bearing surfaces are ground parallel. t 1 Quote Link to comment Share on other sites More sharing options...
Solution Son of Marty Posted October 5, 2022 Solution Share Posted October 5, 2022 I've never noticed that before, but given the choose I would put the curved side toward the bearing to prevent the sharp sides of the axle slot causing the washer to catch and hang up, not that that's happened to me but I suppose it could. 1 Quote Link to comment Share on other sites More sharing options...
Mikesmalaga72 Posted October 5, 2022 Share Posted October 5, 2022 Noticing the bearing witness marks on the flat side in the picture, I would face it toward the bearings. 2 Quote Link to comment Share on other sites More sharing options...
'76mintgrün'02 Posted October 5, 2022 Share Posted October 5, 2022 Washers get that shape from the punching process. For regular washers, I use the round side up if I want them to look nice and round side down if I want to keep from marring the surface under them. I agree with Toby, that it doesn't matter in this case, but (like Mike) I'd probably put it back the way it was, using the bearing marks on the one face as a guide... just because I enjoy that sort of consistency.

But just because there are witness marks on the flat side doesn't necessarily confirm it was installed correctly. I'm curious to see the orientation of the washer on the passenger side ... stay tuned. John Quote Link to comment Share on other sites More sharing options...
John76 Posted October 6, 2022 Author Share Posted October 6, 2022 OK...a closer look confirms what Son of Marty said! The slot in the axel for the washer key is curved at the inner end. This allows the washer to sit flush against the bearing when the nut is tightened to 22 - 24 lb. ft. to "set" the bearings. After the "set", the nut is loosened, and the bearing end play is adjusted to spec. Manual calls for >0.002", but also says to be sure the washer can move. I ended up with about 0.0035". If the flat side was installed facing inward, it might not seat the bearing correctly. There should be NO witness marks on the washer! So much for intuition...I've done it wrong all these years.☹️ John PS: I thought that curved edge on the washer tab looked too deliberate... not just a result of stamping. The washer also has a chamfered edge that flows with the bearing angle when installed correctly. 1 Quote Link to comment Share on other sites More sharing options...
