Re: Brake servo heat shield

If you're going to make your own, I'd suggest using stainless steel sheet rather than aluminium. Plenty of choice on eBay.

Re: Body seams

Jerry, Even on a "good" restoration using lead loading, it's likely that for the final finish a touch of modern fillers will have been used. That's partly because of the level of perfection people demand on a restoration these days which would be very challenging using lead alone. If you can get a c...

I used to fit the rubber trim after I had the bumper adjusted. More recently I have taken to using Super Glue to attach it to the bumper prior to the final fitting. This works better IMO.

Re: Voltmeter variation.

Certainly in the case of the 4TR, new is not necessarily better but the fundamental circuit design is poor so the 4TR is "hit" with full load every time you start. The 6RA is easily substituted with a standard 12 volt automotive relay available anywhere for less than £5 which will eliminate or prove...

Re: Voltmeter variation.

The 3AW can play no part in voltage regulation so changing it isn't going to help. The fact the 3AW isn't bringing on the ignition warning light indicates that the alternator is still working so my vote goes for replacing the 4TR regulator - which also happens to be the weakest link in the alternato...

Re: Refitting IRS question

When it comes to refitting the radius arms on their cups if you just move whatever you've been supporting the IRS with forwards to the front of the frame and raise the car at that point the cups will slip straight over.
No need to have the car on the ground or burly folks in the boot.

Re: Clutch master cylinder push rod length

You shouldn't "cut down" the pushrod but remove the boot and circlip underneath so you can release the pushrod and swap the original pushrod over to your new master cylinder. You can buy just the pushrod from SNG Barrett for around £20 iirc and fit it to your new master cylinder if you want to be su...

Re: Strombergs to Su’s distributor

The curve and settings for the 123 will be the same for Strombergs as it is for SU's. The advance curve for stromberg equipped cars is different to SU equipped cars. There are possibly even different curves for the different variants of stromberg setup. SNGB list different part numbers for distribu...

You can run without vacuum advance connected initially if you like and it is easy to open the vacuum port on a ...

Re: Strombergs to Su’s distributor

Yes, you do need to change the distributor to the one fitted to UK spec. cars at the time with vacuum advance. That leaves you with a lot of options from fitting a secondhand UK spec. Lucas distributor to having your current distributor rebuilt to UK spec. by the likes of Distributor Doctor. Probabl...

Re: Stop lamps and sidelight circuits.

It could be that the brake light bulbs, the ones with the double filament, aren't in their sockets the correct way round or the filaments inside are broken and crossed over each other. As a first action just remove both the brake light bulbs and see if the side lights still come on when you press th...

Re: gearbox stuck in reverse(I think)

Bill, All true but you need to allow for the possible effect of the reverse detent ball and spring which can "seize" up after a period of none use and make it appear you can't engage reverse. Secondly if you reinstall an engine and gearbox without the gear lever in place and during that process acci...

Re: Starting engine after lay up

No because if the crank thrust bearings have lost lubrication you'll be pressing on them and rotating the crank at the same time whilst you're waiting for oil pressure to build up.

The fastest way to help oil pressure build up is remove the spark plugs.

Re: Alternator warning light coming on but alternator charging

You may be aware of this but it's important to understand that the ignition warning light on the 4TR regulator and alternator system does not function the way a modern day ignition warning light does. The ignition warning light being on or off or even fitted at all has no influence over the working ...

Re: Wiring tests

15 Amp would do but rather than using a fuse I'd suggest using a headlamp bulb instead. It's brightness (or not) gives a more immediate indication of any problem and if you do have a problem offers an easier way forward as you try to eliminate it without replacing endless fuses. Another option if yo...

For your second problem with the starter motor, check your engine earth strap(s) have been refitted. The starter won't turn unless the engine is connected back through to the battery.

Re: Brake bleeding

30 psi :wow:

I'm amazed a reservoir didn't rupture and pebble dash your paintwork with brake fluid.

Note to all, when using a pressure bleeder 5 psi is usually sufficient and I'd consider 10 psi the maximum.
