13 TEX Rear Hub Failure. NOT BEARING.
« on: December 30, 2018, 11:02:40 AM »
G'day guys. 2013 TEX XC developed a nasty wobble. Rear wheel had significant play and on closer inspection it is the aluminium hub that slides onto the crown wheel shaft that has failed. The splined hub is as loose as a dick in a shirt sleeve and unfortunately this is apparently not sold as a seperate part and requires...at least according to the parts manual...a complete and very costly new final drive.

Question; does anyone happen to have a spare that they dont need? Perhaps someone who has needed a new bevel drive and has the old one kicking around. Would be more than happy to pay.

Any other suggestions would be most welcome.

Cheers guys.

These final drive units seem to suffer more than their fair share of failures,  what in your opinion was the cause on this occasion?

I only ask as maybe it's possible to do something to prevent similar problems on other bikes.

How many miles has it done ? might be worth a shout to Triumph - could they do something special ? - should be some broken units somewhere - they have sold enough now - good luck

Is loose because of wear or worn because it came loose?

Thanks for the reply. Sounds like it could be worth slackening and retorquing the central nut at the annual service and possibly grease the splines at the same time.

I'm not sure that there is a central nut. Looking at the OEM service manual, it looks like the hub may be heat shrunk onto the splines and held in place with a large circlip. Maybe "held in place" is wrong. The circlip may just be there for incidents like this -- in case the hub comes loose...  :155:

In my opinion the hub has begun to "walk" on the splines and the softer aluminium has gradually worn. I believe many of the so called bearing failures attributed to rear wheel wobble are actually this hub failing.

Bike has circa 57,000klms and has seen extensive, 2 up use in some pretty harsh conditions. I will contact Triumph though I suspect that it will be a sorry we cant do anything type of thing. I will also look at alternate engineering solutions

This is correct.

In addition, every other aspect of the drive was in excellent condition. Uni joints, bearings, seals etc. Certainly in my opinion far less issue with these than the BMW FD's that are regularly giving up the ghost

eBay. Saw one there for $300. Used I’m sure but might be worth a shot. I was actually going to pick one up and keep it around.
