Where is the correct place for the axle Washers

[bikefreakvinnie]

Hey,
I'm in the process of installing a torque arm and i was wondering where should the axle washer go:
1. between the nut and outward side of the fork (like in a traditional bicycle), or in my case nut and (outside of) torque arm.
2. or on the inside of the fork, with just a bare nut on the outside of the fork, or again in my case the bare nut against the torque arm..
heres a picture of my nut and washer since the nut has a "grip flange" as part of it:

was that washer supplied with a bafang rear motor? if so it looks like the optional spacer that fits on the inside of the dropout on the drive side, adjacent to the torque washer. It that case it provides a little more clearance for the chain to run past the frame on the smallest cog. It wasn't required in my particular setup.

The answer is yes. To tell you exactly where the correct place is, we need a lot more info.

But in general, some kits have an axle with a very narrow shoulder, and need a washer on the inside of the fork, and another on the outside.

Most though, have a washer, sometimes a tourqe washer , or a tourqe washer then a washer, then the nut. The main issue is that you have a washer that fits inside any small cup on the dropouts if you have that kind of fork. I just did a thread with pix on fitting a motor to quick release forks that shows what I mean. A tourqe arm would be likely to be much bigger than any cup, or lawyer lips, and need a washer under it, between the forks and the tourqe arm, so it's very likely you will want forks, washer, tourqe arm, and maybe another washer between touque arm and the nut if there is enough axle length.

Thanks for that, I'm a bit clearer now..
It is a front kit I have alright, sorry for not being too clear about that.. its a Suzhou Bafang QWSXB2 from:

I was really wondering about that torque washer so thanks for clearing that up for me dogman! I've had a good look at the set up and I think there is what looks like a torque washer on the inside between the fork...
As you may have seen from my newer post I have put the washer on the outside of the torque arm between the torque arm and nut but I'm not really sure if I need it at all, I think your right Dogman and that it is intended for that quick release cupped fork feature!...
Certainly when that type of nut (flanged with a grip) is provided on a traditional bicycle there is no washer...

The washer is a far bit smaller than the nut!

LOL!!!! anything over 250 watts is considdered offroad use!
You Britts don't need torque washers or even axle nuts for that matter at that power level :lol:
Just need a coulple table legs to duct tape the hub to and some roller blades!

Comeon be nice... you know the britts would use packaging tape or scotch tape - clear so it has more invisible stealth = )

Heh heh, kinda true, but if you damage the forks using the washers wrong, you could still have the wheel fly off using less than 200 watts. I was going real slow when I broke both collarbones. Cracking a set of dropouts, or having a nut that loosens iteslf is bad at any wattage.
