The 'E' Type Forum

Hi Colin, I came up with a small list for that period. Also noted that both Sicursiv and Triplex were in use on XJ6 of the same period. The dates are the build dates. If you want any of the images I can post them. SICURSIV 1S51863 7 June 73 L&R Qtr light + Triplex Rear Door 1S51880 2 June 73 L Qtr l...

Don't know if this helps but S3s which commenced build in 1970, so a few years later than your S1, had the vacuum chamber of the servo finished in yellow cadmium plating according to Richard Ross in his book Guide to Authenticity. This is an original 1971 servo. https://i.postimg.cc/pdnXRG4X/S3-Brak...

Hi Steve,
When the S1 2+2 was introduced in 1966 it had a plain button in the handle and a separate lock below. Perhaps that is the source of your handle.

No, you didn't miss it Steve, it's from the press release.

This Jaguar illustration clearly shows bolt heads outwards with wire wheels. Looking at the nut it seems possible it would foul the wheel if outboard. https://i.postimg.cc/FFYznKzs/S3-Front-Suspension-schematic.jpg This claimed 15,000miles S3 currently for sale on BAT shows the same orientation. htt...

Hi Colin, It's about 120 pages to scan the whole document but all the specification data is reproduced verbatim in the Appendices of Porter's Definitive History, which I imagine most people who are interested in this level of detail will already have. Re publishing it on the forum, not sure about co...

Hi John, Couple of thoughts both related to heat soak from a hot engine when stationary. 1. Further age degradation of the 50+ year old electronic components in the amplifier has occured since it was relocated and without airflow they are now failing at a lower temperature than they were previously ...

It appears so.
Extract from the S3 launch Press Pack.



Other than the first few hundred 2+2s refered to earlier, the part number for S3 front dampers remained the same throughout production of both 2+2 and OTS cars.

Same upper column was used on later S2s and S3s. This is S3, a thin plastic split sleeve held on with two thin plastic bands.

Neither did LHD.

Looking deeper, it seems that this dimmer was added to LHD cars in early 1972, but it wasn't fitted to RHD cars, which just got a blanking plug to fill the new mounting hole.

Later handbooks clarify. The OP has a 1971 ('early') car so won't have the supplementary control in the footwell. The parts manual shows the rheostat it but doesn't identify the change point when it was added. https://i.postimg.cc/G2qkh4Gg/S3-Rheostat-Panel-Light-1.jpg https://i.postimg.cc/7PtWK6dS/...

This extract from a 1973 Lucas Workshop Instruction on the "Roller Clutch Drive Assembly" may help.

For effective roll over protection have a look at Bob Tulius' car for mounting points. It's in the Gaydon museum.

From the S3 Press Release: Referring to the V12 1. "Only about 80lbs (36kg) more than a 4.2 litre XK six-cylinder unit, both fully equipped" 2. Aluminium block -"Jaguar saved 116lbs. (53kg) by comparison with the same unit in cast iron" 3. "The complete engine weighs only 680lbs. (308kg) with all an...

Interesting background on ride frequency thanks.

The wheel rates come from the S3 launch press release.

I'm presuming you're referring to the information in Appendix 7 The production torsion bar figure of 100lb/in" is given in the document headed "Comparative Specification of Production "E" Type and Coomes "E" Type 18th. August 1962 " in Appendix 9. 0.750" nominal diameter, 36 7/8" length - V12 cars ...

Facsimiles of the documents are in Peter Wilson's book "Strictly No Admittance". Probably be breaking some rules to post copies here.

Hi Damian, Prior to introduction of the larger diameter (0.780-0.784") torsion bars referred to above, production bars were rated at 100lb/in. The wishbone rubbers contributing a further 16lb/in. (info from Jaguar documents dated 1962). Bob PS Have you seen CliveR's posts on jag-lovers? Sounds like ...

Just to add that the S3 PM shows 3off BD25659 each for attaching "Jaguar"and "E Type" and 3off BD25644 for "V12". Jaguar called both "Friction Bush, securing emblem". They are shown fitted with the top hat on the outside of the panel. Some of the top hats are just visible in the second image below. ...
