I am one of the diehards (i.e. sad) people trying to keep a DS4 distributor going.
I have been quite lucky in obtaining a spare one complete with points and cap and also a BNIB cap and BNIB points.
The problem is the rotor arm; I am using a cut down Vauxhall one at the moment which seems to work OK but seems to me to be a sloppy fit on the drive spindle.
If anyone has one, even a worn one, I would be interested.
The Lucas No is M1787 and the Remax No is ES31, these being obtained from http://oldcarservices.co.uk website wich has a very useful chart of all the numbers.
According to the website of the Vintage Mor*is Min*r club (you have to log in) the caps are the same as the fifties Renault Dauphine, can anyone confirm that?
The website also has a comparison list of part numbers for the DS4 and others.
There was recently a thread on the VSCC forum that identified the rotor arm to use as an intermotor IM4780 or 47800 as used on:
BEDFORD (GM) Chevanne 1.3
TRIUMPH GT6 2.0
TRIUMPH Spitfire 1.3
VAUXHALL Cavalier 1.3
VAUXHALL Chevette 1.2
VAUXHALL Chevette 1.3
VAUXHALL VX4/90 1.6
Equivalent to parts:
Bosch Australia GD85
Kerr Nelson IRT026
Lucas Australia GL904
The conductor has to be shortened by about 1/8th inch. I have just bought a Motaquip equivalent (numbered VRA111 on the box) is a better fit on the shaft than the original one on my DS4 and is quite suitable fit.
The cap as above comes from a SEV distributor used on the renault dauphine among others, Intermotor part IM4432 or 44320. I am currently waiting for one to arrive from ebay. The cap is not shown on the Intermotor website so I think has been discontinued, available NOS from various sources. There are some made by Supra that would seem to fit but do not have the same vintage aesthetic as the intermotor version.
The cap was used on:
404 1.6 1960-65
404 Pick-up J7 1965-75
Dauphine 1091, Flouride 1092 1959-62
Simca Aronde 1960-63
Replaces : SEV S4000, 39785, 39811, 430 50003
Ruairidh, I have left a message on your email address as shown on your posts.
Dave, thanks for the info, I have probably been worrying needlessly and will try your tip.
Rob, your reply is excellent and provides numbers to look for at autojumbles.
It is very unusual for these to develop excessive wear. There is no reason why you can't bush the body if the wear is not on the spindle. It may be best to try and get another one to make a good one out of the two. I have about 6 on the shelf but they are a bit of a long way from you!
Take the whole thing apart and see what is warn. Then report back.
I found a cap to fit the DS4 CAV type distributor from small Ford Spares to fit a 1932 to 35 Ford (presumably Y type). Their code YE 12116 A. Fitted with Vauxhaul HA rotor arm and my chummy special is back on the road.
