D6D is a good machine. other than the obvious undercarriage issues you should check the engine for blow by and see if it will start from cold. also expect the belt pulley to be worn out and the engine to get hot on warm extended hard days work unless it has had a change.
That's a roger on the pulleys, never thought about that! Thanks for the reply. Andy.
