    RR B80 oil pressure/starter motor

    Using a 24v on a 12v system will give you a very poor motor performance, and it will overheat sooner than work. Have you a photo of the 12v unit? If it is working O.K. on the bench is there another solonoid in the circuit, or a poor earth?

    Diesel IN CVRT worth it or not

    Main thing with the Jaguar engine is to keep it running at the right temperature. Do not let sediment build up in the system, it tends to settle at the rear of the block. J60 is basicaly a derated 4.2 XK engine with 24volt electrics, so parts are easy to obtain. Fuel injection is an easy option but the more power the more heat and you start the worry of transmission problems. I would guess that about 10% up would not hurt as it will not be running the extended periods that it did in service. Another thing to remember is keep the engine breather filter clear as they do not like positive crankcase pressure it makes them smokey. With the use of an endascope you can look in down behind the front timing cover to check the lower chain tensioner and make sure it is in place.

    Leyland DAF 45 150

    Glad you have got something sorted. What type of Rolls engines did you work on? I found if you kept them cool they just went on and on.
  5. I think it is Laminated for windscreens and Toughened for the rest.

    I know it is no help, but it is not good practice working on your own under a truck. Gearboxes are heavy awkward lumps. What will be your escape route if something goes wrong, is there no one who could go with you just to pass spanners and just be there incase you have a problem.

    Anneal a diesel pipe

    Go for it. When clearing a concrete pump pipe a piece of foam is used and pushed through with water. You could blow it through first, then push a piece of foam through with a piece of wire wool in front, using either fluid or air pressure power to clear the internal scale into a bucket.

    WW1 Thornycroft restoration

    As with everything on this rebuild a wise decision logically arrived at. It may be a disapointment for the team not to reach their self imposed deadline, but for me watching it has been a fantastic journey. I applaud your efforts.

    I remember an advert years ago for a Big Ben Sandmaster with a pipe trailer, working in the desert on oil production.

    the mysterous lost 7th Gear

    Was the Torque converter lock up disenabled on some trucks for some operational reason? This would have the effect of losing a gear, or rather the 6 intermediate gear ranges. When the vehicle moved up to 6th the T/C would not lock up so losing direct drive, or as you would say 7th

    the mysterous lost 7th Gear

    As long as you are getting all 6 gears and the torque converter lock up is working thats the lot. There was some discussion a few years ago on this site about gear changing. If you go to Drops 8x6 auto box.
