BOTH these things (638 spline and locknseal nut) can easily be done and we are not talking about something that needs to be done every week/month usually and its not exactly a time consuming complex task. So, for me it made sense to do BOTH and it seems to have worked, now maybe I wasted 30seconds and £3 doing one of these things unnecessarily, but even a tight wad loike me'sen would rather do that than risk a knackered output shaft.

Have unpinned the mkII topic and welded it to the mkI topic and bunged em both in Knowledgebase as this seems to be a frequent enough occurrence to merit it.

After nut came loose on mk2 while in europe, it rattled around un-noticed being kept on the shaft by the plastic cover. When discovered, it had knackered the thread so a new nut would not screw up tight. Sorted it with 3 spots of weld, had to change chain and sprockets, quick grind off of weld, new sprocket, 3 more spot welds and been threr for last 15k, no problem.
1998 TDM850 (24k), 1996 TDM850(58k), 1989 XTZ 750(29k), 1999 XJR1300(13k) no more room in garage ! XJR gone to ex, so 1988 zx10 fills space

Just out of pig ignorance here. What happens if the front nut does come loose. Are you talking a slide along the road. Or does the sprocket take the form of a ninja star and tear the calf off you.?

Only asking cause mine is loose and I will get it sorted sooner if I know im in trouble... smile.gif

when they come off they sit in the thread of the outputshaft
the cover stops it coming right the way off, so other than losing all drive to the rear wheel its not that dangerous
but AND THIS IS THE WORST BIT, while your output shaft is spinning round a a few thousand RPM the sprocket is sitting on the thread wearing it away, this stops you securing the next sprocket as the thread becomes unusable as the new nut just pulls straight over it
i would not ride a bike with a loose front sprocket

I just checked mine after 30k km. It was loose, I know when I fitted it it was done to 85Nm and lockwasher.

I used a Yammy sprocket but reused the washer and nut.

I could not see any damage to threads on nut or sharft.

 

Sprocket and chain are still in good condition.

Will change at about 40k. This time I will change the nut and washer as well as chain and sprockets.

Hmm it aint listified in his list'o'bits but I am sure he does one (cous oi think oi gots one somewhere)... http://www.carpe-tdm...tainless&page=2

 

 
An alternative is the wider nut from a YZF details ear:http://www.carpe-tdm...?showtopic=9244

 

The loctite is mentioned earlier in this ear thread, think its 638 or summat.  Have been using that for a while now after many years of no probs I got a slightly loose nut.  After a coupla thousand moiles to Scotland and back it was very slightly loose again.  Having gone through the pain of completely rebuilding an enjun oi decided that I would invest in the loctite and no probs since.

chill yew got a TDM 900 or an 850 ?

I have an 2002 900, the bikes done 110k km.

 

This is the second chain I have fitted. The first chain I found the nut was still tight when I changed it.

But after reading the post about LOOSE NUTS I decided to check and found the nut was loose. Lock washer was still in place so I do not know were the free play came from. Undid nut and checked thread on nut and sharft no problem so refitted torqued and locktabed.

Will check it again soon to see if it changes.
