Caterpillar - D8 - Diesel - Cold Start - Cat - Tractor - WW2 - Normandy

Caterpillar D8-8R Built in Illinois USA in 1941 then shipped over to England to join 79th armoured Div 819 Dozer Squadron. This actual machine took part in Normandy and D-Day events. Filmed on 19th July 2008 at Barton under Needwood Steam Rally ( near Lichfield Staffs ) What you are watching is the start process needed before the Big Cats diesel engine can be started. The petrol driven starter motor ( donkey engine ) is fired up first. This generates heat which inturn is used to warm up the big diesel engine prior to starting. The action of the starter motor also builds up the oil pressure in the big diesel engine. When the required oil pressure has been reached you will see the guy activate the start mechanism on the diesel engine. Once she has fired up the primary petrol engine is shut down leaving the Big Cat Diesel engine purring away....Sweet
