rear wheel removal and re installation

I hope you're no seriously contemplating shaving anything off. I'm not sure it even matters, but is the spacer the right way round?

the spacer is uniform from both ends it fits in the wheel either end and the distance from the wheel axle edge is the same regardless which end of spacer I put in first against the circlip inside (that circlip hold the big spacer in the middle of the wheel with bushing on both ends two rubber O-rings and the circlips one on each end of that now I had a spacer before and I taped it to the wheel when I took the wheel for a new tire that spacer was lost during the tire replacement so i ordered another one apparently we have the right spacer according to the tech at triumph dealer we checked it is 29.48 mm long end to end said so on the packing box and I measured it it is 29.48
so I am really really out of options
 

"I had a spacer before and I taped it to the wheel when I took the wheel for a new tire that spacer was lost during the tire replacement so i ordered another one apparently we have the right spacer according to the tech at triumph".

New info! There is no way the original parts of the bike changed size on their own. It has to be the spacer. It's the wrong one. Put the axle in, with all the equipment attached, then measure the gap best you can. Go to the dealer and find out which spacer comes closest to that. That's your best bet. You can probably find that info out on the net also.
 

yet the dealer tech said I had the right spacer.
the difference between the swingarm face and the spacer face (the gap) is 3mm less than the width of the brake mount. no amount of wiggling is going to move the swingarm that far away
 
So now you've got me all interested in this...

The link I used above is from a Touring model. Just noticed that. Sorry. I did however find that same spacer on this site:

http://www.2wheelpros.com/oem-parts/triumph-spacer-20x35x22-t2012097-part.html

...and it says it fits a 2006 Triumph without specifying which Rocket, BUT if you keep digging on that spacer it does say that it fits a 240 rear tire. That has to be it. You just happen to have one of the bikes with the smaller spacer. I would either get someone with a lathe to trim down the one you have to 22mm or order one.
 
I've had the same problem a couple of times when changing out the rear tire. The wheel was not fully seated onto the bevel box. What I did was cut a metal tube slightly smaller than the width of the brake fitting that goes between the spacer and the swing arm, then put the axle through the wheel, the spacer, and the tube and then through the swingarm, and then put the nut on and torqued it down a bit. That compressed the wheel fully into the bevel box splines and after doing that the brake would fit just right.
 

I'd certainly be doing that before any grinding. The thing came out of there, right? So it must go back in.

This microfiche says there is an ABS style spacer which is the one you have. It also shows a non- ABS spacer which is approx 7.5 mm narrower.

you may be onto something here the shorter spacer would fit perfectly I think you solved my problem anyway I can shave that spacer I am NOT shaving the brake mount boss spacer are easier to replace
thanks a bunch and I am keeping the link on my bookmark
 
I am perplexed!!! if it is the same spacer and it came out it has to go back in, or is it a replacement spacer which has not been in the bike before, you mentioned one was lost and replaced but was that this time or a previous tyre change.
As if you put a shaved down one and then the wheel miraculously seats itself in the rest of the way you could end up with some serious damage I would thourally clean the splines all the way to the inner end and apply only a light smear of grease and try again, old (thickens with age) grease pushed up the spline could be all that is stoping you
