An example of this would be using washers to pack out a wheel spindle after doing a wheel swap.

Is there anything sacrilegious about doing this? Obviously a single spacer is much less hassle to assemble, a reason manufacturers make them no doubt, but is there anything mechanically suspect about using washers in this way?

The only downside that I can think of is the potential for excessive corrosion. When fabricating your own spacers you should try to replicate the materials used in the original parts in order to minimize the likelihood of chemical reactions that can occur between differening metals/alloys.

My Husaberg came with a cut-off round head of a spanner as a wheel spacer.

However, generally I try and be fairly good with wheel spacers. In other places have often used drilled-out sockets for bigger spacers.

A solid spacer would be more preferable as a spacer than a stack of washers. Washers are not really flat having been stamped out, and there will be an amout of spring in a stack of them. They are also not made to particularly close tolerances. You would experience more flex in a clamped-up assembly using washers instead of a machined spacer.

If you have the exact dimensions of the original I can probably run you one off if Alu is ok (I don't have any big dia steel in stock).


Cheers for the offer but I didn't really have anything in specific in mind. It was just one of those engineering questions that I had been wondering about for a while.

I've done a fair bit of reading about fork/wheel swaps etc but so far I haven't found a definitive guide that says to swap X you need to consider measurement A,B,C and also make sure D is aligned with E.

I have several things in mind though so if I'm ever in need I shall give you a shout Wink

This sort of thing is one of the reasons I want a lathe. It would only need to be small as 99.9% of the work would just be making up spacers or bushes.

Small lathes are pants even for small jobs. You want one like that Keighley lifts lathe in Random Banter.

Washers are ok as long as the spacer doesnt need to be absolutely precisely the right size.

I packed out the rear wheel spindle on my GSXR with washers and that was ok for as long as I owned the thing.

At uni there are rooms full of lathes and mills.....

I'm even taught to use them as an engineering student......

Not allowed to used them for any work outside uni work however as that would invalidate their insurance...... Crying or Very sad

It sucks, all this lovely kit and I can't use it..

Good god, when I was at marine college they used to let us use all the gear in the evenings. Before PC and HSE existed though Embarassed

I'm sure HSE is only implemented on public places, such as schools uni's etc etc.... (ie where someone is likely to bring up some litigation)

In my experience it fails people who are in a real hazard.... Like my mate of a farm has to work with a lot of lime yet is not provided with gloves/mask/eye protection.

Now lime is pretty nasty stuff when it gets in your eyes/lungs ets and the poor chap just has to take his chances. Yet all the little silly bits of HSE which just restrict people and make the world a bit duller always seem to be carried out.....
