  1. Hi Ian, They look great, I like the toothed ring for the ABS sensor on the wheel in the middle of the picture 😁. David
  2. To reinforce what Dale and Andy have said: SAE30 in the engine, transfer box, automatic gearbox, steering gearbox, fan drive system and road wheel hubs. EP90 in the final drives.. ATF (eg any version of Dextron) in the fuel pump governor Hydraulic oil in the crane of a FV434 Note that the capacity shown in the manual includes the oil cooler heat exchanger and quite a lot of pipes. I doubt if Jon will need an oil cooler on his Pz2 as it is much lighter and he won't be invading Poland (I hope). David
  3. Raymond, I expect that you know that Peter Gray died some time ago and that Pounds yard has virtually been completely cleared. The M10 that Mike Phelps restored was for sale by pounds for £1800 pounds when I first saw it there. When I inquired about buying it the price went up to £2500 which I thought was high but agreed to pay it. When I rang them to agree a date for collection it had risen to £4000 so I told them that I couldn't do business that way and gave up. I believe that Mike paid quite a lot more eventually. Values have gone up a bit since those days ! David
  4. If you make a loop of rope diagonally across each part of the chassis, from one end of a cross member to the opposite end of the next cross member, poke a piece of wood through the middle of the loop and twist the rope by turning the wood, it is possible to exert a huge amount of force. I would expect that a triple loop of 12mm blue polypropylene rope would easily pull the chassis into line. You would probably have to pull two adjacent sections of the chassis in opposite directions at the same time or you will just parallelogram the whole thing but doing it this way is very controllable and is not trying to rip the joints apart but to pull them together so is much safer than a Portapak. David
  5. The brake bands are operating in an oil filled gearbox so any asbestos dust is trapped in the oil and cannot be breathed in, even when you change the oil. I suppose if you burned the waste oil it would be possible for the asbestos to get into the atmosphere so best not to do that ! In the real world you are much more likely to squash yourself playing with 432s so I don't see anyone getting asbestosis from a 432. And I did have a good friend who died from it so I do take it seriously. David
  6. Ahh, but what if it was blown up prior to 1 May, and so ceased to exist from the point of view of the army. Do the bits become bits of Elefant which they never were when they were part of a functioning vehicle ? I think that if rebuilt into a reconstructed vehicle, it would be correct to call it a Ferdinand or Elefant depending on the finished build standard. David
  7. Many years ago a very well respected vehicle enthusiast managed to kill himself by taking a jeep wheel apart while it still had air in it. This is not just another health and safety pointless idea. David
  8. The "A frame thingy" behind the take out engine on the right of the photo is actually part of the engine. It is the stays for the exhaust mufflers that sit in a frame bolted to the top of the diamond shaped engine mounting frame and held up at the back by those two stays. Later installations did away with the mufflers and just had plain pipes to the fishtails in the overhang of the upper hull. I note that the box for the new engine is marked as containing an engine with Scintilla mags rather than Bosch mags which didn't have a booster coil and so the engine wiring was slightly different, though easily changed to suit. David
  9. The figures quoted above give a reasonable picture of general WW2 tank fuel consumptions but must be interpreted. Shermans, Grants and Valentines were built with both petrol and diesel engines. The diesel versions gave at least 50% better fuel consumption and were quicker. A tank has to work very much harder to move on soft or seriously broken ground or on gradients so its fuel consumption is very much higher in these conditions than on firm level ground. This will result in about four times the consumption that can be obtained on a road. Covenantor and Stuart will do rather better than the others because they are much lighter but all the others if they have petrol engines will average about 0.5 MPG in real life. Please remember that the official testing was not done in particularly scientific conditions and should be read with the statement of the conditions at the time of the test because that makes a big difference.

  10. Hi Louie, Crossley made many types of vehicle over many years. It would help if you could narrow the search down a bit by telling us what vehicle you have. Also it would help if you put your location in your personal details so that it is displayed under your user name so that people can see if you are local to them or not. This forum has people from all over the world which is a big place. In general people can't be bothered to search back through someones previous posts to see these details so adding them greatly increases the chance of people helping, which they will if they can but you need to make it easy for them if you can. David
  11. Try www.sealsdirect.co.uk They offer a fair selection and have their catalogue on line. David
  12. It was quite common for them to be changed to twin rear wheels in civilian life. David
  13. John, I think that that is an excellent idea, it is certainly very hard to see that it could do any harm. The worst that could happen is that the oil oozes out and then you are no worse off than the standard arrangement. David
  14. I was shown a photo once of a low garden 'fence' made from overlapping carrier sprockets, quite a number of them. It was allegedly well know to all the carrier owners in the area and as the guy was not interested in selling his fence, it got a bit shorter from time to time. I wonder what would be a fair swap for that carrier track ? David
  15. Quite right ! Thanks Adrian David
