V85tt centre stand bolts. TOO SHORT!

Technical V85tt
1

A Bolivian v85tt rider on the ADV rider site had one of his centre stand bolts fall out causing the centre stand to drop and rub against the tyre wearing 5mm into it.

When i checked my centre stand bolts one side was loose and i could see that the bolts were not engaged in the last 2mm of the “stover nut” (where the self locking part is!). Lots of other v85tt owners on the ADV rider site have found the same problem with loose stand bolts and have been discussing solutions. On mine the nuts were 9 & 9.3mm deep, but the exposed bolt end is 7.6-8.0mm.

So i ground the nuts thinner: down to 7.6mm. When i did them up I could now really feel the self locking part of the nuts working

Although the nuts are slim i got them up to 40Nm (30 lbft) using a spring balance on a combination spanner. The factory figure is 50Nm (37 lbft) but as they are now lubricated by loctite 243 the 50Nm would probably be overkill so i am accepting the lower figure.

Nb this problem may have been fixed on the e5+ model as the OP reported he bought a new stand bolt and it had a thread 2.3mm longer…. so no longer a problem

Sorry its not clean! But as you can see

proper engagement with the self locking nut

if they are self locking nuts (with plastic insert) why do you need loctite?

Guzzi also installed them with a threadlocker compound and as i had some blue loctite it cost me no more to do a belt and braces.

PS they are not Nyloc, they are “Stover” nuts. Difference between Nylock and Stover

good info on that post, I didn’t know about stover nuts. however, going by that description the deformed (locking) threads are in the top of the nut, if you ground them off don’t you end up with a normal nut?

Not quite as dim as i look…. i ground the bottom off the nut.

But that is why it was hard to get above 40Nm; i had reduced the size of the hex faces which combined with use of an open end spanner (as surrounding material stops any of my ring spanners) and limited swing angle :frowning:
