Misc: Stands D type stand removal

[danno]

I only use one drum on the back, I think 2 drums are a bit too powerful

I have two drums with the linked brake arms but are far from powerful. They might be ok if the footrest bracket didn't rotate.
Not sure what's supposed to lock it in place on the conical steel mount. I also have the D stand attached here so it's probably a lengthened stud.

Morning Dano, The bit that goes over the stud is located by a pin going into the alloy plate behind,
The footrest should be a good taper which holds it well,
You have to give it a tap sideways to get a footrest off the taper , Unless it a bad taper ?.

Thanks. It doesn't seem to on this modified version of F51/4. The footrest moves down with pressure even with the locknut tight.
The right side (F51/5) is no problem.
Maybe the grease I used on the stand bushing isn't helping but it's always done it.

If you look along the stud from the outer end then behind the part with the taper, which has a flange behind it, there should be a pin at about the ten or eleven o'clock position. There should be a hole into which the pin is fixed on the mounting plate and a corresponding hole in the aluminium part with the taper which is supposed to prevent the rotation. The pin should be about 3/16"/ 5mm diameter and it is not a big job to fit one. It cannot be seen once fitted so it is not something which will spoil the appearance of the bike. Without it the problem will persist.

So is the footrest moving on the taper ,
Or the stud and the tube over the stud moving as one ?,
Never heard of a problem there.

When putting it together there is an amount play on the pin FT185 ,
So you have to reset it after fitting, So the play in the pin is taken up the way anticlockwise.

Yes. F51/4 doesn't move and the footrest is slipping on the taper.

Just clean it up and make sure there is full contact all through the taper,
The end nut does need to be tight !,
Do you have a full nut on the stud, Don't strip the thread if it's only half way on !,
You might need a longer stud ?,
Or is the stud too far through the other side ?,
If there is bare thread sticking out the other side,
Undo the other side to let the stud come through more,
You want both nuts fully on.

Sounds like the tapers don't match. As a temporary test could you put some coarse grinding compound, double sided tape etc into the taper? Tighten it up and then see if it still slips.

 

[danno]

Sounds like the tapers don't match.

Could be. On the right side, the footrest doesn't move even with the nut undone.
Hasn't been taken off much like the left side.
I'll compare the two sides to see if the taper is different.

The stud is a fraction under the nut on both sides so quite even.
