FILTER A. 2C1540 - Caterpillar

A switch on the right panel causes injection of ether into the intake manifold. A thermal switch prevents ether injection if the coolant temperature is above 38°C (100°F). The only service necessary is replacement of the canister when it is empty. 7N296 Ether Cylinder is used and is available separately from your Caterpillar Dealer.7V4134 Ether Starting Aid Group
