hub motor tabbed washer installation=inside of dropouts?

[nycmetrotadpole]

wondering where the correct installation of the tab washer that comes with direct drive hub motors. I saw a ebike video that instructed that the tab washer istalls on the inside of the dropouts . I watched the vendor video for installation instructions and it showed the tabbed washer on the outside of the dropouts.
where is the correct installation .

Where ever it fits best on your bike.
Maybe inside the frame on one side and outside on the other.

It depends on the particular configuration of the axle shoulders on the motor. I have seen some where the tab went inside, but typically it's outside.

And then, if you have spread the frame open wider than normal, you could end up with any configuration of washers it takes, in or out. Whatever it takes to get to where the disc brake lines up, and no chain rubs on the frame on the other side in high gear.

The better motor kits, come with a good fit that pops on your bike that is 135mm wide, the brake lines up, and all is well with the tab washers, usually, on the outside.

The 200 buck amazon kit, could be anything. This month, perfect fit, next month, no telling what's in the kit this time.

Inside would be the safest place since if the axle nut comes loose, the tabbed torque washer can't come off. Other than that, it really doesn't matter as long as the tab sticks into the dropout and doesn't face away from it.

Depends on how your wheel lines up in the frame. Look to center the tire in the frame and making the brakes work. I like Wes idea for having them on the inside if they fit the need and use. What kit ?

There are times when you need to put it together and take it apart many times to get things wired up to go. Do you have a torque arm ? Yet.
Make sure chain does not rub on the motor in low gear. I hate the cruise control button and disconnect it. It can stick at a bad moment.

FWIW, Wes uses a steel bike he can bend out far enough to use the washers on the inside easily. But it all depends on the way the axle is cut, how the wheel is laced, etc.

If it's possible, inside can be good, especially on the gears side. I like a bit more space for the chain on that side.

thanks, a lot of good info on a part of a hub conversion item that is included in the kit, with youtube video as your guide. i like wesnewell infi on the extra protection if the nut came off, "Inside would be the safest place since if the axle nut comes loose, the tabbed torque washer can't come off. Other than that, it really doesn't matter as long as the tab sticks into the dropout and doesn't face away from it."

i am redoing mine , since i have time due to snow fall, i got a threaded rod and nuts/washer to spread the rear dropouts with a little more finesse , originally it was the screwdriver method, that failed due to the spacer washer outside diameter cocking into the freewheel, which i need to take a photo of to further explain.
i am new at ebikes, but am some what familiar with working on bikes, not great but ,question items like this , especially when i saw on , thin it was ypedals video placing the tab washer on the inside, but that was a front wheel,where lawyer lips can cause other problems.
i am going to have to use a couple washers to clear the freewheel and enable the chain to run smoothly.

When I need the spacers, I definitely use a tabbed washer on the inside vs outside. They can be just the right thickness, to get a chain off the frame in the highest gear, either at the axle, or a slight rub on a chain stay.

I have a bit of an advantage though, I have tons of all kinds of e bike washers in a bin by now. It can be a problem, when all you have is what came with one kit.

Any good tabbed washers that can work adequately instead of adding a torque arm? I’m using a track bike with horizontal dropouts. MAybe even two per side (facing forward.). Or some that are a bit longer for more leverage?

I see this variation but otherwise all seem the same
