Front axle of 1982 Mirage 1200

[lawrence]

What are the bits and pieces on the front axle?  I pulled the wheel off to have a new front tire fitted. I recovered the spacer on the left side and the cover for the speedo drive gear on the right, but I didn't find any spacer for the right side.  Doesn't one fit against the bearing on the right side? I looked all around the floor of the shed, but there was none to be found.

Hi Lawrence

the speedo drive housing doubles as the spacer on the right side, you are not mssing any bits....

look inside the speedo housing, you will see that the inside casting acts as the spacer by pressing up against the bearing.

If it's like an RGS, there isn't one. The axle is stepped, the lip should be pulled up hard against the speedo drive when the nut on the left is tightened. Don't tighten the RH pinch bolt until the LH nut is secure. HTH

Thanks so much for the timely, reassuring replies.  When things fall on the floor with a ping or a clatter, it sends a shudder through me.  Pieces roll away never to be seen by human eyes again.
I'm relieved to learn I don't need a RH spacer, as I've had enough mechanical screw-ups for today.
I've got to get the Mighty Mirage road worthy, as she'll be called to duty next month!

I hate to be a party pooper, but there is a thin spacer on this Laverda Paradies exploded drawing - Item 17:

 

[Paul Marx]

Wagner uses the factory drawing which is wrong. There is no spacer. I think this has been extensively dealt with before.

,, There is no spacer. I think this has been extensively dealt with before. 

& others would debate that fact ??

What if Lawrence's bike uses #69 (oh-ar) and not #46? Would #17 need to be there then?

The  No 17 on wagner's drawing is an insert that goes in a recess in the speedo drive housing - it doesn't increase the width of the housing - different part on a RG series I believe. - Regards - phil

well bugga me.  just had a dekko at me SF2 & it's embedded in the housing.  not that i doubted ya Phil, or Paul.
(bolt)

i've bead-blasted a couple of those drive housings & don't recall ever noticing it ??  but that's probably not such a surprise ay!
& the RGS parts list describes it as ?20 x 24.1 x 2
cheers,  Mark

The washer is IN 99% OF ALL CASES NOT LOST.

Only very late 180 and 120 use the larger washer which I show in the parts diagram.

See attached picture of the earlier housing.  The small ring presses in the housing and never comes loose unless you pry it  out  This housing will  fit on any bike with disc brake old or new.

Keith Nairn helpfully explained the reason for these differing arrangements when I was struggling to sort out front wheel alignment.  The small ring provides a hardened stop against which the wheel spindle shoulder is tightened.  When the brake calipers were swung behind the fork legs on later bikes, the fork legs were swapped over and the spindle shoulder then tightens on to the big spacer on the nearside.  The opposite fork leg uses the speedo drive as a simple spacer, rather than a positive stop for the spindle.

At one stage I had two RGS in the shed; one had the spacer embedded in the speedo drive, the other didn't, the axles were identical.

Just making a spacer for the front wheel - I reverse the calipers meaning that the spindle now rests on the spacer instead of the speedo drive housing - I like to use aluminium spacers so have shrunk a steel washer into the spacer. - regards - Phil
