GoldenOne Posted November 27, 2021 Share Posted November 27, 2021 (edited) EDIT/UPDATE: The wheel itself is the issue not the mudguard. I get tyre scraping when more pressure is on the right side than left and the motor hub is physically closer to one side of the chassis than the other So I got a sherman yesterday, mudguard arrived today and was annoyed to find that the clearance between the mudguard and tyre is maybe 1-2mm at most. Anyone else have this? Im a little concerned for safety cause the wheel is of course moving 'up' on the rear. So if it did scrape against the tyre during a turn it might well throw me flying forward Edited November 28, 2021 by GoldenOne Quote Link to comment Share on other sites More sharing options...
Planemo Posted November 27, 2021 Share Posted November 27, 2021 1 to 2mm does sound a little tight. Are you sure both the side clips are fully home? I can measure mine tomorrow to compare, but I've never had an issue. But then I don't do mud either 1 Quote Link to comment Share on other sites More sharing options...

As @Planemo suggests above, make sure the side clips are fully home! I have recently fitted a wider tire than the stock Kenda 262 knobby and still have more clearance than your photo shows.

Heat gun to bend it out a bit and now the mudguard sits properly in place. But, I'm getting wheel scraping with/without the mudguard whenever I put more pressure on the right side. Getting on, turning left sharply etc Quote Link to comment Share on other sites More sharing options...

The Sherman is notorious for the knobby being way off centre, straight out of the box for some owners - it may need re-aligning. I had a 6mm side to side drift when my Sherman first arrived, which took some work to finally get running reasonably straight! 1 Quote Link to comment Share on other sites More sharing options...

No wobble etc. It looks like the entire wheel assembly itself is a few mm closer to one side than the other. So I'd somehow need to shift the motor hub itself in order to fix the issue.

Did you take both pedals, then side covers off and check the 6 socket cap screws bolting the shell to the pedal hangers on each side to see if they are All tight? If they are not tight the shell might be moving/flexing during the times you describe the issue as per your quote below: 4 hours ago, GoldenOne said: Getting on, turning left sharply etc Quote Link to comment Share on other sites More sharing options...

Not the tyre. On the scraping side the actual rim is a fair bit closer to the chassis than the other. So the tyre positioning isn't the issue. Problem is, I don't think it's a case of loose screws as theres no give/flex when I push or pull the two sides apart. In the interest of not voiding warranty however, I'm going to email E-rides first and see what they suggest. I hope this can be fixed :/ 1 Quote Link to comment Share on other sites More sharing options...
GoldenOne Posted November 28, 2021 Author Share Posted November 28, 2021 Agh this may be even more complicated than I thought. Clearance at the front of the wheel is very even. Its just the back.... Meaning either the motor is mounted ever so slightly crooked (meaning the rear upper right grinds, but the opposite side, bottom front left, has no issue cause its outside the chassis anyway) or the chassis itself isnt entirely straight. This would be avoidable if the sherman had more than a paper-thin clearance Ill wait for e-rides to get back to me, and then open it up. Hopefully this can be sorted with some screw adjustment. Or maybe a washer in the right spot. Will have to wait and see 1 Quote Link to comment Share on other sites More sharing options...
GoldenOne Posted November 30, 2021 Author Share Posted November 30, 2021 Would anyone here be able to take a quick photo or video of the gap between the inner chassis and the tyre on their sherman? Trying to get an idea of what is 'normal'https://streamable.com/nwcpr5 Quote Link to comment Share on other sites More sharing options...
Planemo Posted November 30, 2021 Share Posted November 30, 2021 (edited) To rule out the fender which you said initially was the problem, confirm you have alignment issues without the fender fitted at all? Sometimes the shells can be mainipulated slightly, but this is in the up/down plane. I cant see how it could be out in the left/right plane (as you suggest) nor in fact how it could be adjusted as there really isnt a lot of movement in the shell to hanger bolts. If no one pipes up with a pic I will get one of mine tomorrow eve. Edit sorry just seen your vid with no fender...and yeah the gap is a bit off but wouldnt have thought it was enough to rub..and I think most wheels are slightly off tbh, it was very common on the MSX's too. But if its rubbing its rubbing. I will get a pic of mine tomorrow, as for sure it never rubs. Edited November 30, 2021 by Planemo Quote Link to comment Share on other sites More sharing options...
Beachboy Posted December 9, 2021 Share Posted December 9, 2021 This what happened with couple of friends sherman, we tear down the wheel found nothing was wrong or out of alignment then we put the wheel back and there..its all perfect but after 15mins of rides, we noticed the wheel back to missed out of alignment again, still no clue and running out of ideas to fix this..even Linnea got no answer with the issue.. its an 6-8months old wheel anyway and he still ride it since he doesnt feel anything wrong when he rode it but cant use the standard mudguard without scrapping tho.

GoldenOne Posted December 12, 2021 Author Share Posted December 12, 2021 Just as an update to this: I contacted E-Rides and they asked me to return the wheel and they'd re-align it. They did so and got it sent back out to me quickly in <48hrs, I'm not exactly sure what they did but they seemed to put some spacing on the mounting area on both sides around the hex screws and it looks like they did a pretty good job. I got it back and the wheel was indeed perfect for a short while, however after a few km the issue had returned and it was back to scraping, similar to what @Beachboydescribed. Had a phone call with @Afeez Kay who was extremely friendly and helpful and they've now said I can return the wheel for a refund. I was really hoping to get it working as it was the last one in stock in the UK and it seems the S20 is going to be a few months out, but I'm glad that E-Rides support was as good as it was, and will certainly be buying from them in future. I can see why so many people love the Sherman though, other than the wheel clearance issue it was a fantastic wheel. Now the wait for S20 begins.... I'm really not sure why Veteran didn't give just a couple mm more wheel clearance as that would have prevented this from happening. There's just so little room for any sort of misalignment, it seems they've got plenty of clearance on the abrams though which is good.

Finn Bjerke Posted April 10, 2022 Share Posted April 10, 2022 (edited) A freind of mine had this problem and fixd it himself. After a crash it was making noises again. I now have this problem after getting a new (bloody expensive) rim. Sherman rides very well indeed but one legged riding and it sounds terrible. Ill try to follow some of the advice here - the plastic sidepads might influence the balance of the wheel. My freind got better screws (very good idea, the Chinese screws are rubbish) and managed to get better alignment ..... The distance between tire and plastic on left and right side should not be identical methinks.. Conclusion Buy Sherman MAX not sherman veteran ... As always the chinses dont give a shit about QC Edited April 10, 2022 by Finn Bjerke Quote Link to comment Share on other sites More sharing options...
MrMonoWheel Posted June 12, 2023 Share Posted June 12, 2023 I have had the same issue as this since my wheel was new. I bought a shinko 244 to throw on as someone in my group runs one on his Sherman S, but due to the crooked wheel it doesn't fit. I have no idea wtf to do.

leadfeathers Posted September 18, 2023 Share Posted September 18, 2023 Hey @GoldenOne, sorry to bring you back into this, but did you ever figure out how to resolve this problem? I fell at relatively low speed on my Sherman, and now it has the same exact issue. Just lightly and briefly leaning on the right side causes grinding that lasts throughout the rest of an evenly-pressured ride. Quote Link to comment Share on other sites More sharing options...
