From TrucksPlanet.com: The main post-war military AEC truck was the new cabover range Militant with military name FV-11000. In May 1951 the first 10-ton truck O859 Mk-I (FV-11008) 6x4 was presented. It has a GVW 20.7 tons, was equipped with a 6-cylinder overhead valve diesel engine A223 (11,3 l, 144 hp), 5 - speed transmission with optional 2-speed gearbox and a double main gear, pneumatic brakes and a spring suspension. The variant O860 Mk-I with a winch and 6x6 wheel arrangement also was producing. The next versions were producing: FV 11001 / 11002 : Ballast Tractor 10 ton General Service Medium/Heavy Anti-Aircraft 6x4 / 6x6. FV 11003 : Truck 10 ton General Service Crane Bridging 6x4 or 6x6. FV 11004 : Truck 10 ton General Service Tipper ( End Only ) 6x4. FV 11005 : Truck 10 ton General Service Tipper ( Three Way ) 6x4. FV 11006 / 11009 : Truck 10 ton General Service Fuel Tanker 2500 Gallon 6x4. FV 11007 / 11008 : Truck 10 ton General Service Cargo (14 ft / 16 ft) 6x4. FV 11010 : Tractor 10 ton General Service for Semi-Trailer 6x6. FV 11011 : Truck 10 ton General Service Crane Missile 6x6. FV 11012 : Truck 10 ton General Service Cargo Dropside 6x4. FV 11013 : Truck 10 ton General Service Crane General Purpose 6x4. FV 11014 : Truck 10 ton General Service Excavator 6x4 or 6x6. FV 11015 : Truck 10 ton General Service for 20 ton Trailer 6x6. FV 11016 : Truck 10 ton General Service Cargo ( 18 ft Dropside ) 6x6 Front hook 7 ton Winch. FV 11017 : Truck 10 ton General Service Self Propelled Launcher 6x4. FV 11021 : Truck 10 ton Tipping Platform, Self Loading, RE 6x6. FV 11022 : Truck 10 ton Heavy Duty ( RAF ) 6x6. FV 11031 : Tractor 10 ton General Service Light Anti-Aircraft 6x6.

Hi Ted, I'm showing FV 11022 as a mk1 Militant 6x6 RAF, do you concur? Mike

Have you looked at the way Bedford and Ford got round the problem using the existing steering box on VAL and D series? I cannot find a picture of the Ford but it is similar to the Bedford here: https://www.google.co.uk/search?q=bedford+tk+power+steering+ram&tbm=isch&source=iu&ictx=1&fir=Oew3mWD1Ns5ZTM%3A%2COSHep7bWNANkUM%2C_&usg=AFrqEzdc5cVlxB1qni6aNIyoFCmXTYKYIA&sa=X&ved=2ahUKEwjsgtL-7cbdAhWOXMAKHYlxAD0Q9QEwAHoECAYQBA#imgrc=Oew3mWD1Ns5ZTM: The actuating valve is built into the ram and you still have manual steering in the event of a hydraulic failure.

I presume you mean Explorer and mine certainly had a cab heater/demister. The RAF ones were also fitted for vacuum brakes with a tank just inboard of the offside rear wheels, you can just see the back of the tank in this photo: https://ccmv.aecsouthall.co.uk/p57805472/h8f5d48b#h8f5d48b

You need a threaded base, bulb holder, lens and rubber boot for each lamp, they were used on many military vehicles but seem to be in short supply. The larger plastic lens screws on the outside of the threaded base and replaced the original small glass version which screwed inside the base.

Different weight class yes but Mustang was a 6x2 Chinese Six.

Mandator and Mammoth both date back to the 30s but while Mandator was a 4 wheeler Mammoth could be a 6 or 8 wheeler including the twin steer Mammoth Minor.

My Explorer was ex RAF Kinloss where it served as a recovery and snow plough. It was originally RAF blue, then airfield yellow and finally IRR when transferred to the REME.

An obvious air leak will most likely get you a PG9 if you get pulled by plod or the DVSA. Don't forget that unlike modern trucks that have failsafe spring brakes and split air systems, the Martian is single line and any fault will result in failure of the primary braking system. An internally corroded air tank is a potential bomb and just as with workshop compressors should be checked on a regular basis.

Providing they are used unladen and not drawing a laden trailer.

I suspect it was stripped by being over tightened to cure a leak caused by re-using the copper banjo washers, they should always be treated as one timers and replaced. As Richard has suggested, it looks like you may be lucky and able to reduce the boss and re-thread but don't be tempted to do it in situ as you will never get the end square and risk getting swarf in the hydraulics.

Photo was taken at the Bunker Bash, Kelvedon Hatch on May 22nd 2011. https://ccmv.aecsouthall.co.uk/p399964332/h2489f6ea#h2489f6ea https://ccmv.aecsouthall.co.uk/p399964332/h2489f6ea#h32de02e8 The Explorer name is clearly visible on the bonnet side.

6x6 Contractor known as Explorer mk2. There were 4 or so chassis cabs available brand new when Scammell closed down, I seem to remember a couple ended up on a landfill site taking roadgoing trailers to the tipping point.

Yes and yes, but it can be done, Avgas duty is £0.377pl while petrol/diesel is £0.5795pl. Avgas is specially formulated for long stroke high altitude slow revving aero engines and can cause problems with starting and low speed running in automotive use.

Excellent write up by Adrian Barrell of his Multibank restoration: http://hmvf.co.uk/topic/7836-m4a4-restoration/?tab=comments#comment-97070

SPMT or Self Powered Modular Transporter, the girder trailer was too large to access the site.

Is that the one from Turbo Venture in Newcastle?

Needless to say the whole operation was over-hyped by the press prior to the move which used two 8 row bogies, smaller girders than those shown and a pair of MAN 8x4 tractors not the Trojans as suggested. Saddest part of the story is that we seem to be incapable of building a similar transformer in the UK rather than having to buy from Korea.

If the information is correct this is a tiddler of a transformer at just 143 tons which could easily be transported on just one of the 14 line bogies of the girder trailer, see here for an example with a 200 ton transformer, 16 lines plus 25-30 tons on the tractor: The only advantages of a girder trailer are a lower travelling height and an easier time for any weak bridges. Don't forget that 70 years ago both Pickfords and Wynns were regularly transporting 200 ton transformers without the luxury of motorways.

Automatic transmission fluid type A for the cab tilt pump and power steering according to the workshop manual.

T5-350 was the standard 'box fitted to the Leyland DAF T244.

Just spoke to my pal who is the tacho calibrator at a large DAF dealer, he was sure that the tacho (analogue or digital) could be calibrated against the VIN number. He also rang the tacho training officer who agreed with him and suggested your calibration center read their 'special notices' which explain the procedure.
