95 S3 Rear Wheel Loose

On the way home from work the other day on the 1995 Speed Triple, I noticed an odd feeling coming from the back end on access/decel. Long story short, there was a ton of play in the wheel even though the axle bolts were plenty tight. Anyway, the hub bearings seemed like they popped out of the bore -- I can't verify, it could've happened during disassembly.

So as I'm set to install new bearings (locally sourced) using these Triumph equivalents:
* 3800016-T0301 = 6305-2RS (drive side) (62x25x17)
* 3800017-T0301 = 6304-2RS (brake side) (52x20x15)
* 3800018-T0301 = 6204-2RS (hub) (47x20x14)

I am questioning whether or not the PO/mechanic installed the hub spacer correctly. SO HERE'S THE QUESTION: does the spacer get inserted into the hub side or the brake side?

Inserting into the hub side seems to make sense because the opposite end with the two notches sits just about flush with the landing for the bearings on the opposite side. However, there seems to be a bit of side to side play to the collar when inserted this way.

When I drop the spacer into the brake side, it drops in nicely, but protrudes through the hub side bore a few millimeters such that I wouldn't be able to press the hub bearing in place. And, none of the bearings internal diameters are large enough to accommodate the spacer either, which is 27mm O.D.

Also, when disassembling the hubs and bearings, the collar of the spacer became dislodged from the tube section. Can I just press this back in place?

Any guidance here sure is appreciated.

There are 3 spacers. One on each outer side next to the bearing and under the dust seal, and there is a bigger space inside the cush drive area. 2WheelPros normally has good schematics, I think they copy them for the Triumph site, but this rear wheel schematic shows the parts looking differently than what is on my Trophy.

The part numbers they give are the real Triumph part numbers, very handy when you have the part number in hand when you go into a Triumph dealer.

Yes, this is the same schematic as the Speed Triple, only the orientation of the middle spacer looks incorrect in the schematic. When the wheel is on my bench, it feels like it should be inserted into the brake disc side toward the drive side.

Is that how your Trophy is set up?

Hi Jeff,
I'm trying to figure out photobucket.

Strange thing, the spacer on the sprocket side, I have one made from steel and another made from aluminum. The spacer on the brake side is aluminum. I think I'll make new ones from steel. They don't wear down has much as the aluminum.
The axle can be slid in from either side. I slide mine in from the sprocket side to get the wheel inplace first, then spacer, and finally lift the brake inplace.
Hope these pictures come thru.
Greg
