  1. I should have realised it was not a Gardner of that era as it is a mono block. Finding gaskets for that will be interesting. You did say you like a challenge. Low revving slugger the last Thornycroft I drove was a Sturdy. It will probably be BSF and Whitworth fastenings.

  2. That is going to be fun putting that back together. There is a good Gardner engine site on Facebook they know there engines inside out, also where to get parts from. If you can find the engine information plate. If the main engine drives a generator it is a late build. It would probably be cheaper to find a running engine than rebuild the one that you have. Do you have the starter motor and dynamo?

  3. I think it is a Coles mkV11 crane the same as fitted to an AEC 0854. There was a blog about 4 or 5 years ago of an AEC restoration and I think someone had spare crane manuals. Yours looks like the short wheelbase Thornycroft Amazon version. I am guessing it has a Gardner 6LW power plant. I would think the crane engine is by now a replacement I think originally they were Ford petrol powered. If you have photos of the engines we should be able to pin them down.

  4. Yes I remember the Scania combo. I don't think they offer it any more. Volvo are now offering that combination. With the L60 the supercharger gives low speed induction air pressure positive flow and when the turbo's get up to speed they take it to the limit. but I notice there is no mention of an intercooler package. This would have put the induction air temperature above the optimum for best power from the package. A standard Leyland 680's favourite trick was to suck the bits of turbo that broke off in and spit them into the silencer. Balancing turbocharger spools in those days was not the science it is today. Roots blowers if the revs get to high suffer from rotors kissing as the lobes elongate. Of coarse there was the Foden FD6 mk V11 4.8 litre which was supercharged and turbocharged but I think they were only around the 225 bhp range. They only had a single turbo. Stretching the memory now.
