Hi, folks.
Three years ago, when I disassembled my 850-T, I decided to replace the center stand as the one on the bike was pretty beat up. So, I ordered a replacement, planning to re-use the bushings, bolts, etc. I am now in the process of reassembly, and when I went to put the new center stand on, I was unable to find the old bushings and washers, and can only assume that I discarded the old stand and hardware unintentionally. So, I ordered and received replacement bushings and "spring washers", and am now trying to reassemble with all new parts. Which leads to my question:
Are these bushings supposed to be a press-fit into the stand, or are they supposed to be able to float/rotate inside the stand? They seem to have a slight interference-fit in the stand, and I don't know if I should look to press them in, or if I should just sand the powder coating a bit on the stand to allow the bushing to slide in and float in the holes. Here is a picture:

The bushings are just pushed slighly into the holes in the stand, and you can see the interference fit by the fast that they don't fall out.
Any info appreciated!
Cheers,
Shaun

I thought they spin in the swingarm hole. Pretty sure that is where I smear the lube whenever I have them off. And the bolt 'locks' the bushing to the frame. But don't grind on anything until you here from others.

They float. Sand on Garth.

Thanks, Wayne. The stand actually mounts ahead of the swingarm hole, but I think you are right about them not being a press-fit.

Sounds like a consensus forming. I love when that happens!

Bushing and spacers float the spring washers keep the stand tight

Thanks, Jim.
How tight should the bushings be in there? I have been sanding and filing for a while, and it's getting better, but I still can get the bushing to slide all the way in by hand.

Keep going, you only gotta get there once!

Just snug, I use a drum sander in an air die grinder to clean out openings like this.

That bike is not clean enough :laugh: better get some steel wool.

My thoughts exactly. :boozing:

Although not an engineer one would assume that the bushing would take the wear and not the center stand. Typically the bolt would be shouldered and the spring washer would provide the clearance. Unless the bushing is softer than the center stand.

+1 on floating
If you can get it to slide in a few cycles of the stand will take care of any burrs in the contact surfaces. As mentioned, a light wipe of grease helps, but too much collects crud.
Pay attention to the length of the spacers. They are directional.
When all tight, the stand should still swing freely. If side binding, then either the spacers are not installed in the proper orientation or the washers are too fat. I've had both happen.
When installing the stand I attach the springs first and hold them with zip ties. Then if you start the pivot lugs in their place and rotate the stand it snaps into place with no fuss.

if you take off the powder coat won't it rust? maybe you could turn down the bushings instead??

Powdercoat makes a lousy bearing surface. If it's properly greased it won't rust.

Yeah -- you don't really want powder coat in the contact area. It's about 1.5 mils of plastic and makes a lousy bearing. It will drag, peel and bind in the bore -- and it's a pita to get out once cured. When I powder coat I mask areas like that for those reasons.
