Drive shaft
« on: May 07, 2016, 10:45:38 am »
HI all

I have a launch model so 2013.  For some time now as I take off from a standstill it has felt like something elliptical has Ben taking up the slack.  Hard to explain but a sort of cyclic wobble only when I let the clutch out.  Last night it seemed a lot worse with a sort of knocking noise as well.  So this morning put it on centre stand, started it and put it into gear.  There is a grinding knocking noise and you can feel a horrible vibration from around the bevel box!  :114: so I decided not to drive it to the shop and green flag is picking it up. 

Just checking with the collective that I am not just hearing feeling backlash as there is no load?  Because now I am staring to question myself.  But any problems with the uj would be at the front.  I can see that when on the stand  it is at an angle but even still it has to cope with that and anyway you feel the front and it is quite smooth put your hand on the back and it is terrible.  Knocking graunching and feels like it wants to escape.  So much so at one point I took my hand away so that when it exploded the shrapnel did not get my hand. 

I can see a discussion with triumph as the 'exteneed' warranty from head change  (they also changed the final drive they said) ran out in April?

Hey John, good move not to road it. Better safe than catastrophic failure. Please keep us in the loop and let us know how you get on with Triumph and your dealer

Best of luck

I would say that was a good catch. I would not have rode it after finding that.
This is a guess on my part, but I bet they warranty it.
It seems that Triumph does not want any issues with final drives like another company had.

Good Luck!

Sorry to hear of this latest problem John.

This is a guess on my part, but I bet they warranty it.
Triumph have replaced complete Units previously out of warranty,
for nothing more than some corrosion of the casing, so I would imagine / hope
they will do the same here, and will be very keen to thoroughly investigate the failed one.

Cheers, and Fingers crossed for you  :821:

Thanks for the replies

Bike picked up on time (I get free green flag through the bank so no cost) and took it to webs.  I have spoken to webs and told them I expected them to try a claim.  That is if it is wrong.  I started it and showed the green flag man really to convince myself that I was not hearing things. It is strange when you first put it in gear it does not sound too bad but within a few seconds it starts knocking and graunching.

We will see what happens.   Been checking the sprint and fixing the tiger I also need a new tyre on the mv.  I found I was riding the trophy so often (and working so many hours)  I neglected the others.   

Typical now the good weather is here.

I'm not sure I understand you correctly, but you say any problems with the universal joint would be at the front.  There are two universal joints - one at the front of the shaft and another at the rear next to the rear bevel box.

Apologies if I misunderstand your description.  Hope this will help.
