Sprocket carrier hitting Shock nut - SF750 (1970)

[Smartv11]

The nyloc nut on the rear shock is far to close to the sprocket carrier (and has hit it previously with previous owner as can be seen by damage).

The sprocket carrier appears to be re-assembled correctly;

- Large 36mm nut,
- chrome chain adjuster,
- swing arm,
- small spacer.

and then bearing, spacer, bearing etc.

What is wrong here / missing??

My options are;

- Reverse nut and bolt, but from photos from internet this is not correct/standard.
- Fit a spacer (2mm) washer, to move wheel to left by 2mm? again this seems incorrect / bodge, although i don't think it would hurt chain alignment??
- Fit non-nyloc nut and spring washer, but this would still be very close to sprocket carrier.
- I've already added some washers to 'shorten' the bolt and the threaded end away from sprocket carrier

Thanks Paul

- Use a M12 half nut

I seem to recall a half nut somewhere in the arse end of Laverdas (too lazy to go out into then shed and check). Otherwise, check that your wheel spacers on the rear axle are all present and correct. Chain alignment is a good indicator as to whether your back wheel is in the right place.

Half nut, as stated above.  It is a close fit.    3C example shown in attached pic.

thanks all for replies - Half nut it is then

Mine must be a half NILOC nut.

 

[Smartv11]

half nyloc would be ideal, but I can't find them anywhere, so spring washer will have to do!

Turn down a Nilok one, (or file it, just take a bit of care to get it square on the face)
.

You're better off without the spring washer. Contrary to popular belief, they provide no locking function whatsoever.  Tests have shown that a nut/bolt with a spring washer is more likely to vibrate loose than one without. Use a drop of Loctite if you're worried about it coming loose.

Back when I had the std wheel in, it was half nut, no washer. Never came loose.

If you're worried: Loctite.
