  1. Regarding 'modern youth', I can't remember where, but there is a rant in the Bible about how useless young people are, so this is not a new idea. Also we should remember that we were all 'the youth of today' once. David
  2. Virtually all straight 6 engines are 153624. It is an inevitable result of the crank design which has to be that way to get the dynamic balance. The only other possibility is 142635 which is 153624 reversed, but this is very unusual. David
  3. On the use of a piece of copper behind the weld, the heavier it is the better as it acts as a non stick heatsink so if it is too light it will initially work well and then melt ! That said, a piece of 28mm copper water pipe flattened out can get you out of trouble. Brass really doesn't work as the zinc content will burn if it gets too hot and if not will tend to melt and solder itself to the back of the weld. I have a hand held spot welder (great for sectioning a piece into a door skin) for which I made a flat faced copper cap that fits over one electrode so that that side of the spot weld is almost dead flat. This way there is almost no distortion or damage to the outer surface. David
  4. I don't believe that is a MkII LRC. They were 4x4. This one is 4x2 with five stud wheels intended for 9.25 - 16 tyres but with 9.00 - 16 American NDCC fitted. These won't easily fit onto normal eight stud British wheels but will onto the lighter ones intended for 9.25 - 16s. David After Adrian's correction lower down this thread, he is quite right, the LRC in the first post has got Firestone directional tread tyres ( I don't know what I was thinking when I wrote American NDCC) However I still think that they are 9.00-16 as 9.25-16 are much lower profile so from the side look much less chunky. See the photo of three LRCs with Dunlop TrakGrip 9.25-16 in the post below this.
  5. Or the instrument cluster came from a RHD UK spec vehicle...... David
  6. As stated above you can't directly measure bore wear with a digital calipers as it won't reach beyond the unworn part of the bore that the top rings don't reach. As a crude but useful starting point, find a bit of thick fencing wire or similar, cut a straight bit to about 3mm more than the bore . Round the ends into a smooth roughly spherical shape and then bend it in the middle so that it JUST fits into the bore. You can then measure this with the calipers and if the wire is stiff enough and you had the right feel of it in the bore you will have a useful idea of the size at that point. do the same at several points on each bore and you should have an idea of the situation. If there is a big step at the top of the bore at the limit of where the top ring reaches, that will break new rings even if the diameter is acceptable so it would need removing anyway. Maximum wear is usually a little below that step and across the axis of the engine. Any deep grooves from broken rings or debris are bad but depending on severity and intended use you might try to hone them. Ideally a rebore, new pistons, rings and all bearings and gaskets is the way to go. A good quality digital caliper (not a £5 one!) is a basic tool that you need for any work of this kind. Have fun and work slowly and carefully. David
  7. If the part is not available in the UK it would obviously be very expensive here so HMC should levy a special extra charge to bring the imported part up to the same level. Of course, the effort that you went to to go and acquire the very rare part in an unfamiliar country and ship it home proves how keen you are to get it and should be taxed too. This is called an integrated policy. David
  8. Tony, what sort of cab did the one you took your test in have? - did you see any with the OY cab fitted? I wonder if anyone can find a photo of an MW with an OY cab in service. The more I think about it the more sensible it seems that a batch could have been rebuilt like that. David
  9. I wonder if the cab was replaced by the military. I can't see a civilian replacing the cab (presumably for more comfort) but retaining the roof hatch. It would have been easy to obtain an OY cab when this truck was disposed of but equally the army/air force would have had lots of trucks to cannibalize post war. If it was serving in a non-combat role the conversion would make sense. Another issue with converting it back is that the bonnet and sides are different on a MW as the bonnet extends back further and is at a more horizontal angle. I think that I would keep it the way it is. It looks nice and is much more comfortable and usable with this cab though not as 'military' looking. It may have genuine military provenance as it is now - the first hint is the disposal card indicating it as 'closed cab' when it was built as an aero screen. David
  10. Neil, If the cab has been changed to an OY type (quite a common civi mod) the steering column will probably have been changed too as the MW driving position and so the steering column angle is lower than the OY type. The steering box is a different casting with the mounting lugs to the chassis at a different angle. I re-machined mine to make it fit but it is not the ideal solution. The wooden MW cab is relatively easy to reproduce if you have one to copy and good OY cabs are getting hard to find so don't throw anything away. Have fun, David
  11. Is it fluid ? If it is fluid you take the tire off, take the tube out squeeze out what you can through the valve hole and put it all back together. If it is foam filled with semi rigid foam to make it properly bullet proof you can't get it out, although I suppose that it might be possible to cut the foam filled tube out of the tire in small pieces but I think you might loose the will to live. I would use the tire until it is worn out and throw it away. David
  12. After the war a lot of RAF land was used for storage of returned armoured vehicles and trucks so the fact that one of the co-ordinates is at Waterbeach Airfield is not in itself a problem. Whether there is anything there is another question.... David
  13. No need for creative user names, some of us use our real names - much better for networking ! David
  14. I have a spare battery clamp free if you want it. I will be coming down in Leighton Buzzard on the 21 August and leaving on the 23rd. PM me if you want it. David
  15. TL part numbers relate to British built light tanks and carriers. Ford didn't build light tanks so this is a carrier part. David
  16. Yes, the extra weight is an unwanted side effect that reduces mobility, ride quality, tire life, fuel economy, and wheel bearing life. Much better for us to have a spare wheel and a jack ! David
  17. Tire size is 9.00 - 16. You are not going into combat so you don't need them bullet proof. David
  18. That is the 'standard' setup but the strength and length of the spring is tailored to the dimensions, weight and power of the vehicle so they are not at all universal though they look similar. They have no relationship to suspension springs other than both being leaf springs. David
  19. I agree with John. The small pipes are for injecting a spray of petrol into each port for very cold weather starting. Just blank them off. David
  20. I bought a brand new red one, unmarked except for "Petroleum Spirit Highly Inflammable" in 1970 from Halfords. I have no idea what was stamped into the bottom if anything. They were still in common use then as plastic ones had only just started to be available. David
  21. All these cans have interchangeable caps. This one simply has the wrong cap on it ! David
  22. I think that the blocks keep the tilt spaced away from the tailgate itself. The point being that any water on the inside of the canvas drains outside and that the canvas doesn't rub on the steel angles and bolts. David
  23. What a great set of photos of very expensive parts being made ! It is great to see 'proper' engineering being done. David
  24. In common with most WW2 British trucks, the governor on the carburettor does not set a continuous speed for the engine but instead limits the maximum RPM that the engine can reach, although of course it can't stop an overspeed caused by being in the wrong gear going down a steep hill. Now that we are all used to driving motor vehicles this is much less of an issue so I wouldn't worry about having a working governor. David
  25. And I thought that Valentines were bad for driver vision ! David
