1948 Triumph Roadster..."Bergerac" triumph with dickie seat in the back !

OK, that rules out a governor issue. Could be restricted fuel supply, or pump cannot keep the carb full.

My old school headmaster back in '60's had one of those, before we knew them as Bergerac's car!

Looks like rego ends with TA which is Devon and Supacat were based there, so could have been in US for evaluation at the time

Mind if I nick this to post elsewhere Richard??

Go ahead, it was one of those emails that goes around, so don't credit me for it.

As we are on the subject, a few weeks ago an overseas friend sent the following, I think it originated in North America:

The Electric car boondoggle

Would that mean that under 'Right To Roam' almost any land is public access?

Oi you, ger orf my land :nono:

Thank you for that gem, however a well known and popular way of improving performance and/or efficiency is to change the carburettor or ignition system. My guess is the carburettor has a slightly larger choke ( the hole where the petrol goes down) from 35 to 40. The distributor has the correct cam drive gear and looks physically the same, so it could be a better version being as it is used on jags and lagonda's, the only difference could be the vacuum advance and retard but it does the same job, or the dwell angle (the cam lobe profile). Anyway I will sort it out, it will run properly, I will not be beaten.

Don't forget the centrifugal advance differs between engine types. Distributors are set up for particular engines, it is all in the assembly part number, not the type number, even the springs on the advance have different rates.

I had to work on a Bedford that was fitted with the larger carb (from an Austin 4 litre) and once I changed it back to the correct 35 version it ran a lot better

Hi ...not directly miliitary but looking to the groups expertise....can anyone remind me why a 4 stroke petrol engine would "hunt" ( rev up and die down of its own accord) when ticking over. Fuel problem ? Electrical/distributor ?Any suggestions welcomed.Thanks Andy

It might help if we knew what the engine was. If it is fitted with a governor, this could be causing it. Could also be restricted fuel supply ............. Is it a lawn mower engine?

 

Somewhere in the dark and distant past I was told that the RTA and various other Acts covering vehicles, also applied off a road or highway, so as stop drivers going mad and driving about without a care for the public's safety.

 

The search continues!

 

When you go to events, you must have read the information to exhibitors, also signed the declaration that you have read these and have insurance for your vehicle and correct licence.

At one of the big events in the calendar, there is this in the exhibitors handout;

"under Sections 1,2 and 3 as amended by the Road Traffic Act of 1991 you could be prosecuted for driving recklessly at this type of event if it was considered you endangered lives of other exhibitors or members of the public"

Any idea what date that is? It's absolutely lovely.

In the description it appears to indicate approximate year is 1914

I think the RR B80 max rpm about 3500, the K60 about 2500 to 3000 Max and the Cummins 6BT ranges from 2800 to 3100 depending upon power setting.

John,

Not quite true, as far as I know. The B81 was I think 3750 rpm, from my recollection of the cut out speed on rotor arm and the K60 had a max crankshaft speed of 2400 rpm, but both cranks were geared to the output flywheel which ran at a max of 3750rpm, bringing it into line with the B81 engine output speed to match the transmission when the FV432 was updated to Mk2

Neil to my eyes & on my particular screen.

 

Right looks like DBG

 

Left looks like OD

I second that Clive.

Neil,

The left hand photo looks more like BS298 (British) Olive Drab ...in semi-matt. When we had vehicles in service in DBG, you will notice in a line of vehicles, the difference due to age of paint finish, if sprayed or brushed, etc. DBG is known to change tone after a while. Also it depends on what you thin the paint with and to what degree.

Of course your two photos might have been taken in different levels of light too.

I am looking for a halfshaft for an Austin series 3, I have been told that's it is the same as the civilian Austin and Morris series III lorries. The part number is an Autin / MOWOG 11K7895 which is on he end of the half shaft.

 

 

 

Hi Gill,

I said in a previous post to you, that the shaft is possibly the same as a civilian Series III, as this military lorry was only produced in small numbers, it is highly likely that Austin used 'off the shelf' parts.

cheers Richard

There is an auction in France later this month with a WW1 Renault artillery tractor in it. Seem like a collection is up for disposal. See link here:

https://www.alcopa-auction.fr/voiture-occasion/renault/tracteur-d-artillerie-lourde-type-plaque-eg-60695

It is possible that this halfshaft is the same as the civilian Austin and Morris Series III lorries. There appears to be a Austin / MOWOG part number on the end of the shaft, 11K7895 (if I read it correctly). I would expand your search to historic commercial sources quoting the details on the end of the shaft. Maybe someone on here has BMC parts lists and can track this number down.

Its connected to the slump test, which ensure concrete is mixed to the correct consistency.

I don't know how you get you drinking water in Kent Richard, we don't even do that over here. So sorry to disappoint the latrine watching fraternity on here, but nothing to do with humane waste products.

 

If it helps, this is 1952 & the apparatus evolved from another government body.

Clive to quote your comment on an earlier post, 'it does have a certain lavatorial flavour'. I took that as a clue

Is it a laboratory test rig where you can pour urine through the two funnel filters and what is collected in the tube below is fit for drinking water?

Just going on similar MO themes of the past!

 

Richard's point about wind-up on the road as soon as the steering wheel is turned, made me wonder whether it would be OK to drive my Lwt in 4x4 in a straight line as in May each year I take part in a parade of MVs and other vehicles that moves so slowly, that clutch pumping is getting to be a bind on my knee. So far I have resisted using 4x4 mode but if it is a very straight 1 mile parade, then I trust it would be ok to be in 4x4 second gear and trickle along?

Larry,

The remark I made about steering related to those vehicles with H layout of driveline and one central diff only, ie Saracen, Stalwart, Ferret, etc. The wind up referred to is between each wheel on one side.

RICHARD have you tried CHRIS MUYS at FTS l have had Cadillac engines and bits from him in the past

Thanks Wally,

I thought my client had contacted Chris Muys, but will try myself just in case. Appreciate your help.

best regards,

Richard

The problem of wind up is overstated anyway. None of the vehicle manuals even mention it, and as long as tyre diameters are within specification it largely just results in additional tyre wear.

 

Cheers,

Terry

Terry,

The military publications never state problems or fault finding in these Alvis and Daimler vehicles. Things like that are largely taught on the courses. Having been working on these vehicles over a 40+ year period I can assure you the 'wind-up' is not overstated. Even with all new tyres on, once you turn the steering and drive on a hard surface all the wheels on one side of the vehicle are trying to travel different distances yet being driven together, This means all clearances in the gear train and tracta joints are being taken up, which also means high friction levels and stress, especially in Tracta joints.

regards, Richard

Richard do you need some from over here, happy to help if needed.

Hi Robin,

At present the situation in N.America is that no STD size Main bearings are available from suppliers. Currently looking closer to home and possibly Europe to see if there is anything about, otherwise it means grinding the crank to suit available sizes, which is an expensive option. Will see what replies come in.

regards, Richard

On my way to work this morning, spotted 3 jeeps near Ashford Kent. Nothing really unusual except that one was 'Nuffield jeep'. Suspect they were on route for France.

Wanted for a Cadillac 346 V8 engine, one set of new Main bearing shells, Standard size. Anyone got some for sale?

regards, Richard

Dear All,

 

IMHO all the Stolly needed was a means to declutch the fore most and rearmost wheel stations when not needed. Then there would be no wind up loads on the transmission.

 

John

Some private owners have done just that.

Richard

Given that wind up is more of a problem with a 6x6 Stolly than a 4x4 vehicle, can anyone explain why the army are considering using a new 8x8 wheeled APC, the Mechanised Infantry Vehicle?

How will wind-up be minimised to an acceptable level?

Wind up in a Stalwart or other Alvis FV600 series vehicles, or Ferret and Fox to is attributed to the 'H' drive train layout and one central diff in them where all wheels on one side theoretically have to travel at same speed but almost impossible when on bends or tight turns. Advances in drivetrain layouts today mean this is not so much of a problem.
