It is indeed a thwaites alldrive 4000 but what year it is from no idea. It is still going strong and has moved 1300m3 of earth already but the engine is getting tired so it will need some tlc real soon.

The time has come to open it up, pistons and cylinders worn out. Replacing them + new bearings and cleaning out everything and putting in new seals wherever i can.

Will keep you updated as i go along. I have a YouTube channel where we post videos and the dumper will come in one of the future videos called Domaine Sauvage for anyone interested.

I have all the parts now, i ordered them from stationaryparts in the UK and within 2 days i had them neatly packed in France.
The valves have been regrinded and tomorrow i will start putting in the new pistons and cylinder, i will try to remember to take a picture here and there as i progress.
