Might as well replace the rear bearings, cheap enough to do. No major issues but my hub is a little mullered. And I find another fault that costs me even more money...
Definitely not a how to but I hope you find it useful.

On an '81 T140 I had, when I went to change the rear wheel bearings I found that the bearings were fine but the housing had worn. Had to make up a sleeve, then things were fine.

That happened on my Suzuki GS, ended up having to source another front wheel. The previous owner had done thousands of miles on warped discs and I think the vibrations had caused the bearings to move in their housings.

It is better to fit the bearing spacers to the bearings before fitting the bearing as an assembly of bearing with spacer. If you tap in the spacer as shown you are transferring the impact force through the balls to the bearing race. You would have to redesign your tool so that you are tapping the outer race when you insert the bearing assembly. The Triumph workshop manual does advise this.

If you mean the inner spacers that sit outside the bearings? That wasn't a hard hit to get them in, just a tap to ensure they're seated.

@@bodganeering Yes those ones but you are still transferring the shock load through the balls. Otherwise good vid and helpful.

Great video, and killer job on the bearing seat tool you made. My manual has the LH and RH spacers reversed from what you showed. Maybe US model is different? Got my bearings in today (thanks to your video) but the tire wheel seems tight when you spin it. Maybe I'll try swapping the spacers. Thank you and keep up the great work.

Depends on the manual whether produced by Triumph or Haynes/Clymer, they all seem to differ. I know there was a problem with Triumphs official parts list in the mid 70’s, if they can’t get it right what chance do we have? 😂 My general rule of thumb is put it back as it came out but that is heavily reliant on the previous person dining the work. Oh the joys of motorcycle ownership… 😂😂😂

Back in my submarine days, we used to throw bearings in the deep freezer with the food (well-hidden of course so the cooks don't get mad) if we wanted to shrink the bearing outer race and cook the bearings in a toaster oven for an hour or longer if we needed the inner race to expand over a shaft.

I’ve never had any joy freezing bearings, most domestic freezers don’t get cold enough. If you watch Cutting Edge Engineering do it he uses liquid nitrogen, that works a treat.

Prime time to throw in a lightweight disc on there.

Shame there’s nothing lightweight about a Bonnie… 😂

I also thought of replacing my speedo drive unit. I bought one from the UK but I ended up greasing my old one and also replacing the cable itself as it was somewhat crimped around the fork area. Speedo works like it should now.

The whole bushing on the output on mine has worn so needs replacing. A lot of people forget to grease them.
