Automatic Ether Injection System Caterpillar Diesel

If you have a Caterpillar® diesel engine, you may have this feature. The ether cylinder is located in the engine compartment on the driver's side of the vehicle.

To change an empty ether cylinder, follow these steps.

1. Loosen the screw head on the cylinder-to-bracket clamp.
2. Spread the clamp apart.
3. Clean any dirt from the neck of the cylinder and the top of the valve before you take out the cylinder.
4. Check the inside of the valve for any foreign matter. Clean the valve as necessary.
5. Cover the valve to protect it from dirt and take out the cylinder.
6. Install a new gasket whenever you take out the cylinder. Use only one gasket and spread a light film of clean oil on it before installation.
7. Put in the new cylinder. Turn it clockwise until it just starts to contact the gasket.
8. Tighten the cylinder another half turn (180 degrees). Don't over-tighten.
9. Retighten the cylinder clamp.
