Lotus Elan

Elan S4 1969 restoration

PostPost by: Sandals man » Fri Oct 23, 2015 8:58 am

I just discovered that my elan has a mechanical brake light switch above the pedal...Does anyone know of a picture or post one where I must mount the 3 way splitter for the front brakes?
Thank you

Willem

I have an US specs S4se (1968), and wanted to share a bit on this "tandem" girling master cylinder, in case it may be of use to you :

mbell wrote:If it was originally a US market car it would have had dual circuit brakes to meet federal requirements.

One connection goes to the front brakes, one to the rear. So the spare three way you found is probably for the front brakes. The rear will have one a 3 way near the rear of the car.


mine is a 0.70" ( ~ 1/16 ) bore girling # 64068928, repair kit 2610

These master cylinders have a reputation of being difficult to bleed, and I've have been doing so tilting the car up and down, sideways etc... for I've been chasing bubbles around for a long time on a occasionnally squeashy pedal, only to realize that this master cylinder has a valve at the front end : I now believe that my intermittent soft pedal symptom comes from a tiny bit of something moving around the sealing of that valve (will take off the master cylinder later this month to check).

good luck !

Hi Willem

The C type cams have one groove on the hub that the sprocket wheel mounts on. The groove on the sprocket wheel that runs radially on its outer edge is used for setting up the timing per the diagrams in the manual or the Wilkins twin cam book.

Normally the exhaust sprocket has "Ex" etched on it somewhere on its front face. Sometimes the inlet sprocket has "In" on it but often it is unmarked. If both your sprockets are unmarked then check to see if the dowel pin position is different on the two sprockets versus the teeth. if it is, then we can probably figure out which one is the exhaust and which the inlet or if no difference whether you have two exhaust or two inlets - some photos would help.

Hello everybody,this is the sandals man from holland.I am putting the overhauld engine in the chassis and have some questions.The fuel line in the rear goes over the chassis or under the chassis between the crossmember and diffrential???
The barrel and olive (3x) of the vacuum adaptor are missing ,where can I get them?
Where can I get a pipe with a barrel for the petrol pump for connecting a hose that goes to the stromberg carburettors?
Thank you
Regards
Willem Holten

Willem,

First, the easy part of your question. The fuel line is correct the way you have pictured it.

Re your fuel pump. You will be aware that you do not have the correct item, so can you be sure that the pump you have, will deliver petrol at the correct pressure? Secondly, if you are going to use that pump, I notice that you have not used any lock washers under the bolt heads that secure the pump to the block. You should.

Lastly, as you do not have the correct pump, it is difficult to point you in the right direction as to where to obtain the pipes and olives for the pump you have, as the sizes may well be different to the original item, but you could ask your fellow Nederlander here, arno at caterham dot nl

Willem,

If you bought it from SJ in the UK it will no doubt work, but it is not the correct pump. I shall post a picture of the right one tomorrow. Forgive me, but your one looks HORRIBLE.

Send a message to Arno with the mail address I gave you, he may have the barrel parts you need.

Willem,

This picture is a correct AC Delco fuel pump, but these are no longer available, unless you find a new old stock or used item. They are out there.

There are more modern equivalents without the glass bowl, but I have never seen one like yours. As I said, if SJ sold it to you, I am sure it will work, but just does not look very period.

I dont believe the 3 way vacuum adapter is original as i have not seen one before on an Elan but I am not familiar with all the details and variations of the various Stromberg head versions. A hose and fittings specialist shop may have what you need for that particular adapter or it might be easier to source the original Lotus fitting that screwed into the inlet tract and typically just connected direct to the rubber vacuum hose that may then have connected to a plastic hose in the case of the head light vacuum system.
