Re: Tyres again!

Malcolm, the vast majority of tyres we buy for all our cars are now listed under the "Summer tyre" category on tyre web sites. I have 185/80/15 Vreds Sprint Classic on my car as do many of us and they perform well within the limits I'm prepared to take my car to, wet or dry. They also did well, and ...

Re: Positive or negative earth?

The biggest challenge in a polarity conversion is reflashing the dynamo field but you're sidestepping that issue by fitting an alternator. On a standard car, early enough to have no electronics and motors that all have field windings rather than magnets that's it. I believe you have a cam driven tac...

Re: L2RHD - bending the pedals

As above I used the Mike Cassidy diagram from the Knowledge Section. The brake pedal ends up effectively straight on a RHD car. For the clutch pedal I made a cardboard template to the dimensions in Mike's drawing to offer up for quick check to see if it had been bent enough. You may want to put an "...

Re: Soldering

I find that if you use an open flame you need to use a plumber's flux which is quite aggressive to avoid a dry joint. When I wanted to solder the brass rear quarter window upright without ruining the chrome I bought a 300W soldering iron similar to the one in David's picture above off eBay. Around £...

Re: Original mild steel exhaust

I bought the Jaguar Classics mild steel system - see post below for around £600: http://forum.etypeuk.com/viewtopic.php?f=4&t=10386#p90274 It was made of "aluminised" mild steel. The "aluminised" is a coat of aluminium paint. One of the downpipes came painted black so I rejected it. The response cam...

Re: airfiler box SII

Whilst it is usually nice to have everything working as the car left the factory, this is one item where you really won't notice that it's not working or not there, especially as it's probably not been working for years - unless you're planning a drive across Siberia any time soon. It was only fitte...

Re: SU Carbs problems

I appreciate that the problem doesn't lie just in having two smaller SUs rather than 3 bigger ones, but Jaguar obviously felt that three 2inch SUs were the beasts to go with. The majority of 4.2 litre XK engines that Jaguar delivered had only two SUs and many of those versions developed a similar o...

Re: SU Carbs problems

Allen, the carbs you have are perfectly able to run your engine and run it well if they did come from a 1974 Jaguar. The best starting point would be to use the same needles as were originally used in the 1974 setup. However, for your lack of revs problem I'd be checking that the carb butterflies op...

Re: Wiper splines, Spindle dismantling, Bizarre Shapes ?

Rory, could they be because someone thought the retaining clips in the base of the wiper arms needed a "lead in" to enable easier sliding on? Obviously, for that to be true the chamfer would have to line up with the clip on the arms so does it?

Re: Wiper Drive Pimary Link, Eccentric, and Wiper Parking.

Simon, the service manual tells you what to do, it doesn't give you the reason why the longer crank has to be on the driver's side but as you suggest, it's to do with the arc traveled. With the passenger side crank being shorter the wiper arm and blade will travel through a greater angle of sweep. T...

Re: Wiper rack fitting

Speaking from Series 2 - but not 2+2 - experience, there's a gasket that goes over the spindle on the outside before you add the chrome outer bezel. Also there's no harm in applying silicon to the wiper spindle on the underside of the scuttle before you pass it through. As to the problem of the spla...

Re: Advice regarding starter.

So the power generation is roughly 10 volts X 210 amps = 2100 watts with the engine spinning...you need around 2kw of energy to spin the engine....roughly.... No, you need torque to spin the engine, 8.3 ft lbs or whatever. An electric motor wound the way a starter motor is will be much more efficie...

Re: Breaking the barrier

So you seem to be saying that all the Stromberg CD s as fitted to US spec cars can be adjusted. No, not really on S2s they can't be adjusted very much. The Jaguar Service manual in the Emissions Section gives an explanation on what can be done but basically unlike SU's each carb was individually ca...

Changing the distributor to one with the UK mechanical advance curve along with a vacuum advance capsule will give a significant mpg improvement.

Is it the case that 3 SUs are always going to be better , or can the Stroms be made to function equally as well ( I have removed the secondary throttles ) ? The straightforward answer is that, yes, the 3 SU setup will always be superior to CDs . Define superior. If in the context of this thread we'...

Re: Laycock de Normanville

Yes, the gear ratios simply get duplicated (except between 1st and 2nd) so there is no point in engaging overdrive in anything other than top. Except that with third overdrive being very similar to top, you can enjoy driving around twisty country lanes in third and use the overdrive to quickly swit...

Yes, up to £1500 for a 4 speed gearbox with Compact A Laycock overdrive isn't cheap but by the time you add all the other parts you'll need to get a LT77 or other gearbox to fit and work you'll find it's certainly a cost effective option.
