The manual says "BOLT, FLUID PASSAGE  BSP.F. , brass   3/8 in."    But this is greek to me . So I do not Know if this will give me the size of tap needed to clean up the threads. Any advice.? I presume BSP.F stands for: Parallel (straight) threads, British Standard Pipe Parallel thread (BSPP; originally also known as^[1]British Standard Pipe Fitting thread/BSPF (Wiki).

Peter,

Check the threads per inch on the bolt, should be 19 for 3/8" BSP. Here is a good source for taps and dies:

To the left, cab nearly out of frame is a British 3 tonner, could be a QL, it appears to be green.

I have the impression from somewhere that the the turretless Morris AC was used by asbestos wearing fire crew to dash to an aircraft crash site and provide immediate assistance in extracting the flight crew even before the RAF Crash Tender put out the fire.

The old Fordson WOT1 or Crossley crash tender would likely beat the Morris to the crash scene!

1947 does not sound right for a 42WLA, looking at the engine number it is more likely a late 1943 build. There are no frame numbers on them originally, the number stamped on the frame has had to be done for DVLA requirements.

Someone find a photo of a real RAF 'Follow Me' vehicle in WW2, as I don't believe they existed

In the book, 'Wheels of the RAF', there is a photo of the RAF airfield at Khartoum, which it says was taken in late 40's, it is noted and clearly visible in the photo of a jeep with a large board on the rear stating 'STOP' and 'FOLLOW ME'. It is an Air Ministry photo, no. R1316.

OK, not wartime, but very close.

RICHARD these are 75 cm long by 3 cm dia black plastic coated could be from ECM

Sorry Wally, something went wrong there, it was a different NSN to yours. 😕

Hi Wally,

Just found this link below, does it match with what you are thinking?

https://www.iwm.org.uk/collections/item/object/30118309

Stick to the bolt stretch method, it came from a much later EMER instruction - No Apes required !!!

Thanks Richard.

That's the first time I've come across a sensible way to accurately pre-stress bolts in small engine construction.

Phil,

You gotta love Rolls engines!

The REME Inspection Standards for the B40 engine, dated 1953, has no mention of torques, just tighten big end nuts using a 6" Tommy bar of 3% Nickel Steel ....................

Thanks Clive. Any mention of the big end figures?

 

Hi Phil,

You have to measure the length of the big end bolts to achieve the correct tightness. First measure the bolt then tighten until the length increases by 0.006" to 0.009", then fit the split pins in the nut. You can measure the bolts insitu with a caliper.

I have been contemplating that option.

It needs to have a two pin electrical connection. It also appears to have an adapter that makes up into a 1/2" x 3/8" UNF adapter in the coolant rail so I have options for the thread sizes on the probe.

I saw the picture of the probe on the Xmod website (out of stock) and it looks the same as the one fitted to Rolls Royce B Range petrol engines. You could try Richard Banister with the NATO number and see what he has in stock, 01797 253211

Hi Graeme,

All I can say is that it is for a piece of US eqipment (or vehicle) supplied to British military, the designation US/ORD indicates this.

david refers to railway problems also  that was never an issue. I consider him thinking about railway bridges

 

The railway is a minature track running in front of the building, nothing to do with bridges.

I think you get away with it. I remember the Charterhouse bedford OY we drove in the UK had no problems in the middle of the bridges . You could stand upright in the back.

They are talking about lowering the garage floor, not the height of the lorry!

Found this on a website about the liberation of Eindhoven:

well thats conclusive!!!!! how did you find that so fast!!!! who has the copy right can I re-post it?

 

 

I think the photo probably came from the REME Museum as it would appear to be their Facebook page. They are at Lyneham now.

Here is the tac sign as in the photo, hope this is of help.

Afternoon, Im hoping someone maybe-able to help,

I have a "b" Vehicle card that states the Vehicle I have was attached to the above from the 7/63 untill 2/80.

im interested as to how it would have looked in service and what markings it may have carried [if any].

Thanks For anyhelp

Sam.

Hi Sam,

As the photo was taken in 1975 it falls straight into the period on the "B" Vehicle card. As the guy posted on Facebook, it was the only Leyland recovery at that unit. The Div sign can be seen on the nearside rear, and if it is what i think it is, a red diamond with two diagonal dark blue stripes and 'XII' written across it. Somewhere I might have a good picture of the sign. Great provenance!

I worked in REME workshops for 22 years and still have a good interest on the subject.

regards, Richard

Here is a photo proving it was from Ripon, shown lifting a loco at York Railway museum

not shore that the 38th was with BAOR?

most pictures of trucks ive seen are as you describe, very little in the way of unit insignia.

Im considering putting the truck in to Aden/eastern livery 2 tone ect, I know the 38th had dets in theatre, but not shore regards any markings..

 

I thought 38 Engr Regt was based at Ripon

The company also made a model of a B17 Flying Fortress

The next time you look at a Saracen and then a Stalwart with a standard supension ride height, look at the tracta joint angles.

Sarasen is about 15 degrees angle on the rear wheel set and the Stalwart is about 40 degrees unloaded rear wheel set at standard suspension adjustment height.

Stalwart tracta joints work hard.

Ron

Hi Ron,

I am sure we may have discussed this when we met up at Corowa in March. Suspension angle on Stalwarts in comparison with Saracen or Saladin. Both the later vehicles have minimal loads added, so suspension angle is relatively constant. The Stalwart however, is designed for a 5 ton payload, but as we know, practically all of the Stalwarts in private ownership never carry a significant load. so setting the suspension to a similar setting of a Saracen will improve the life of the final drive train and reduce the torque needed to drive them. Years ago when I worked in REME Workshops, I had to do extensive drive line repairs to a Stalwart used by RE for driver training. It was agreed with the unit that we should lower the suspension as they did not carry loads and had been suffering bevel box and tracta joint failures. This solved the problem. I have also done it for a private owner who also had been suffering breakages due to the excessive angle of driveshafts. I did note the heights for each 'axle', (ie Front, Centre, Rear) but it might take a bit of searching to find them.

regards, Richard

Your probably right. I'm still learning. What do you think about driving with silencer off and back cover off? If it don't over heat then it might help narrow it down?

Thanks for the help

You will find the noise from the open pipe is far to great to go on the road with, although it sounds great (!). When we tested the Fox's after repairs we always left the rear armour off to check for leaks and had a short silencer made to fit the outlet on side of the hull, think it was one from a V8 Rover, you will need something on there. My thoughts are that there is a possiblity tthat sound deadening material in your silencer may be obstructing gas flow, how ever it seems you have not confirmed all the belts are intact yet.

OK. Was going to drive fox without silencer to see if it would overheat. Best I can tell it is homemade and hollow. Took back cover off and observed ware on the edge of the blower motor belt. Thought of test run with cover off to see if it would not overheat.

 

If I am not mistaken, the photo shows the power steering pump pulley and belt
