It depends on which direction the crows foot is pointing. If it’s at 90 or 270 degrees to the shaft then it makes virtually no difference to the breaking torque, but if it’s at zero degrees (Out the front of the wrench) it increases the breaking torque and at 180 degrees it decreases the torque. In a test just now with my torque calibrator, a crows foot that has 20mm between centres increased the torque by 5% at 0 degrees and decreased it by 5% at 180 degrees. Of course, when one has a torque calibrator available It’s an academic question as one sets the breaking torque with the crows foot fitted 😀 The following formula has been used: M1 = M2 x L1 / L2 Where: M1 is the torque setting of the wrench M2 is the actual torque applied to the nut L1 is the normal length of the wrench L2 is the extended length of the wrench

According to the DVLA its back on the road - showing as TAXED, with a new logbook issued in February. It is however listed as not having been MOT'd - but as its MOT exempt it doesn't actually have to have one.

I'm just wondering what the source of the actual gearbox housing is. The DC prefix is not one that was used on a Triumph, so what other BLMC cars used a 3 rail casing with the DC prefix. I suspect that the AAW stamping was put on by whoever built the box. The annoying thing is that I used to have a very similar gearbox in the garage, but I sold it with one of my GT6's about 4 years ago. I never got round to fitting it, so I never noted its serial number or prefix. If I recall correctly it was built by someone in East Anglia.

When you say that the filter is empty, do you mean it is absolutely totally empty, or has a little bit of fuel in it ? there is a big difference in the diagnosis between the two. how much fuel is there in the tank ? if it’s more than half full, disconnect the fuel pipe before the filter and lower the pipe as low as you can - you should get fuel flowing out of the pipe - if not there is a blockage in the pipe from the tank.

For any given grade of bolt, a ‘black’ one will always be stronger than a plated one. The zinc plating process always weakens the bolt slightly, and if there is a problem during the process it can severely weaken the bolt if there is hydrogen embrittlement. The Cadmium plating process is much more forgiving, but unless you need the bolts for a grade A aerospace application they are forbidden as the corrosion byproducts are cancerous.

Graham, you see this as you are a Moderator. As Admin, I get the same message. It’s an upgrade to the actual Forum operating software that runs on the Invision server, and it’s something that only a Superadmin can install. I’ve asked the Club management several times to get it installed, but the IT support company that do the Superadmin work are reluctant to install it as the last big upgrade from 3.x.x to 4.x.x took a lot of effort to get the Forum working properly. This is a minor upgrade, so I can’t see the problem, but it’s not something I can do myself as I don’t have the required passwords.

What tensile strength bolt and nut have you used ? if they are too low then that might explain the stripped thread

Have you ruled out a bent engine backplate ? Vibration can be caused by an out of balance propshaft - this is usually at a given road speed, rather than in any specific gear. Propshaft induced vibration can also be caused by worn universal joints - and the amount of play in the joint that causes vibration is tiny and you are unlikely to be able to feel it by hand. As the joint wears more, the vibration will feel as though it is going to teat the car apart.

And this is one I saw for real myself - in Reykjavik a couple of years ago

This is one of my favorites

I think that the salient point here about some cables of the same cross sectional area being able to carry more or less current than others is probably down to the temperature specification of the insulation. There are insulations, such as PTFE and ETFE, that are much more tolerant of high temperatures, so one can carry higher currents in the same cross section of wire. Likewise, for the thickness of the insulation itself, there are insulations that have much better mechanical durability to abrasions and cuts, so one can get away with thinner insulation. There are insulations that have much better voltage breakdown characteristics, so again one can get away with thinner insulation - but in a car, the voltage breakdown characteristics are not really a consideration as its all 12V electrics, and not 100's or 1000's of volts (other than the HT leads)

If its the same as the MKIV Spit, then the spring goes down a small metal strip on the exhaust, at the join between the manifold and the downpipe - see photos The spring connects onto the lever at one end, and the other end hooks onto a length of wire which in turn hooks onto the bracket that is attached to a the downpipe joint.

If you are also converting the drive shafts to to use CV joints instead of Rotoflex donuts then you can fit handbrake cable guides to the chassis rather than the bodytub. For Rotoflex cars the brackets were fitted to the body tub so that the cable cleared the rotoflex donut.

If you are replacing the lever arm shock absorbers on a Rotoflex Vitesse with the Rear Shock Absorber conversion kits like the one the TSSC and other places sell (i.e. https://shop.tssc.org.uk/product/rotoflex-rear-shock-conversion or https://rimmerbros.com/Item--i-GRID008052 ) then you MAY need to cut away a small section of the body lip to clear the bracket - it all depends on how many packing washers you use to space the body tub off the chassis. The same goes for fitting the kit on a GT6.

Nice solution

Not exactly sure, but a friend who shall remain anonymous, drove up from London to the Duxford Triumph show in his MKIII Spitfire - and when he came to drive home the car was suddenly running like an absolute pig. So bad in fact that he abandoned the car in my garage and borrowed my turd brown Acclaim to get home (the shame of it !). A couple of days later I started looking at the engine to try and find the problem and found that the bolt on one of the pancake filters had come out and the filter rotated to block the hole. I rotated the filter, refitted the bolt and the car ran perfectly again.

Those holes must NOT be blocked !

Sir Stirling Moss has passed away aged 90 after a long illness as his wife Lady Moss reveals the British racing legend 'died as he lived, looking wonderful' Sir Stirling Moss died at the age of 90 in the early hours of Easter morning The racing legend was one of the most lionised figures in history of British sport Moss's style and skill earned him the acclaim as the greatest all-round racer ever His versatility won him 212 of his 529 races in every conceivable kind of car https://www.motorsport.com/f1/news/stirling-moss-obituary/4779769/?utm_source=RSS&utm_medium=referral&utm_campaign=RSS-ALL&utm_term=News&utm_content=www

There is an awful lot of historic training material out there. The TSSC HQ museum has a good collection. The one thing I have never seen is the actual projector used to present the film strips - they must be really really rare.

You mean these ones ? You need a special projector to show them, they are half frame 35mm. However, to disappoint some of you, the film strips are just a set of pictures that are the same as the illustrations in the training manuals.

They need to be welded on, the forces on them are huge.
