SpAriel MkII aka The Hermanator

Hello Vincent
the one of the two of the bolts shown could be a H30-56 pinch bolt to hold the headlamp cowl to the lower fork yoke.
Regards Klaus

Yes ofcourse ! I could have known that, Nacelle lower bolt.
Hmmm I need two… and the rest of the bike

The 1954/'55 rear wheel spindle in half width hubs on swingarm frames have different spacers.
The drawing in the parts book show the plunger frame arrangment.
For swingarm frames the two outside spacers have small flats that point towards the chain tensioners to keep them from turning while adjusting.
The third spacer between brakeplate and swingarm has the same dimensions but without the flat.

The layout :

my outside spacers just came round no flats on them and the ad juster just touch on the end of the spacers by the nut thats drag for you things that donot fit right my Ariel is a 1954 350 NH

I've never seen a spacer with a flat on it for the chain adjuster. I've 3 PRF wheels, two 1954
and one 1955 and for comparison one spring frame wheel which has a shorter spindle and thinner
spacers as the chain adjusters bear inside the fork and not outside as on the PRF. The PRFs will
fit in the spring frames with a change of brake plate but not the other way round. I've had them
all for more than 50 years now and I'm fairly sure they've not been changed. Have I just been
lucky or unlucky?

The odd thing is... one of these spacers with flat came with a '55 NH I bought two years ago and the other one was with a barn find KH

[Vincent.vanGinneke]

A picture of it loosely assembled, The size of this spacer makes that the adjuster does not touch the round part of the nut.
the head of the adjuster does not bear completely on it, maybe 3quarters.
Do I have a mix of bits ? or is it just a Continental thing ? both NH and KH are original fifties imports and both have the same type of nuts.
Although both of them had a 'collection' of non Ariel rings and spacers on the spindle.
I just assembled what I thought would be correct....but ??

HI Vincent that is how my NH 350 1954 looks like just on the end of the spacer thats how it must be to me it did not look right

[will_curry]

. . . as are all three of mine, I've just had a look. With the wheel close to the suspension unit the adjuster
is definitely touching the spacer well under the centreline.

It doesn't look too clever but nothing's broken yet.
