    Its not a Spanish thing though.  They are all over the UK and Ireland as well.  Some are more pronounced than others, but Ive never heard of any damage caused to a bike or any other vehicle because of them.
    I could envisage if you hit them at speed though, a problem that was already there could come to its breaking point.

    Having seen what happened in my case...

    I think that despite the fact that the Triumph manufacturer does not say in its workshop manual that the crosshead of the transmission shaft (cardan) needs maintenance, I suggest taking note and doing our own maintenance and greasing that part between the two rubbers it has the crosshead so that due to the absence of fat or this part with the dry and hard fat.

    We have to think that this part is not protected from the dust and water that enters that area.

    Failure to maintain the area of ​​the crosshead of the transmission shaft (cardan), it can harden and not have a smooth movement and in the case of highway rumble strips, it will be easier for the catastrophe to occur.

    If we look closely we will see that the Tiger Explorer does not have the plastic crap that protects the crosshead from the transmission shaft, but rather it has a bellows-type rubber that protects that area against inclement weather and dust.



    By the way, that crap of the two plastics costs 149.90 euros plus taxes.




    The rubber (bellows) of the Tiger Explorer costs 14.95 euros plus taxes.



    Obviously the transmission shaft (cardan) is more protected from inclement weather than the Trophy. The difference in price of plastics or rubber (bellows), is an abyss.

    In case someone doesn't know... The drive shaft (cardan) of the Tiger Explorer is not the same as that of the Trophy, the drive shaft (cardan) of the Tiger Explorer is somewhat shorter, however, the motor and the tapered case back are completely identical.

    Something like this can be a good solution:

    I check my u-joint occasionally for play.  I have noticed that it is not a grease able joint.  Do you know of a replaceable joint that is serviceable ?

    I can't help thinking there's a bit of unnecessary panic going on. Do we know of another shaft drive failure in all the years of manufacture of the Trophy?

    This is the first I've heard of on the forum, and in the 3rd post on page 2 of the thread digital stated that he is unaware of another breakage like this.

    I don't quite understand what union you are referring to.

    In that area we don't have any gaskets, only the oil seal that is on the outside of the conical box, a rubber ring that is inside the conical box and the famous big oil seal that there is no spare and that whenever oil has leaked from that joint, the entire rear conical box assembly has had to be replaced.

    To remove that giant seal requires a very special tool. But...

    I know of a case of a Trophy that replaced that giant oil seal, if I remember correctly it was an old school mechanic who built a tool to be able to disassemble that part and managed to disassemble and replace that giant seal.

    Surely our friend Tralex, a contributor to this forum, if he wanted to, would be able to build a tool to disassemble that giant oil seal.

    On the other hand, there are no more gaskets, until you reach the input of the gearbox damper shaft.

    Unfortunately, I have to say that there are and I know of quite a few cases...
    On our part, from time to time, we should have to check the area of the conical box where the shaft (cardan) is hooked.

    I have seen losing a lot of oil, as well as eating all the extras of the axles (internal pinions located in the rear conical box).

    I will look for a video that I keep of an Explorer, which makes my hair stand on end to see one of the failures of the conical box that I mention.
