Welcome !

this is where the horn goes : note that it (a Lucas Altette) is attached to the mudguard bracket with a flat horn bracket, not the seat bracket.

Found that factory service note .
It is number 125 in the Document repository under Ariel bulletins.
and a drawing about it

Thanks David and Gary,
I will fit the parts.

Hi Gary, but surely the ball valve in the pump itself prevents that is it not?
Thats the 'main virtue' of a ball pump compared to a gear pump.

Dead as in not alive.
Lucas MDB or MD1 or MDB1 sometimes called the 'Covered Wagon' magdyno .
Looking for only the housing, if possible with the triangle shaped front cover and the large brass (?) cylindrical rear cover.
or just any part on the outside. Inside parts are of no importance ...

Hello Dave, I have the bits but I was just wondering if I should fit them. Thanks.

Hi Gary,

I looked at the small cap but It does not have a channel down the side.

Busy with the oil pump.

atm there is no spring-ball-cap behind the feed side .

I know those are there to keep oil in the crank if the oil pump packes up, (never had that )
Also if you want to have a reading on a oil gauge but my VB does not have that.

So, is it needed ?

Thanks.

Not a Ariel so not in the for sale section,
Seen this on Dutch Marktplaats.
If you want to stick out between all those who have the new Norton V4 this could be it :D
