The Caterpillar 3406A/B/C spacer plate is a thick plate that sits between the cylinder head and the engine block. Its function is to provide a seal to prevent oil and coolant leaks, as well as to ensure proper compression in the cylinders. 
The spacer plate should be replaced if it is damaged, worn, or if there are signs of leakage. Common signs of a failing spacer plate include oil or coolant leaks, reduced engine performance, and decreased fuel efficiency. If left unaddressed, a faulty spacer plate can lead to more serious engine problems and costly repairs. It is recommended to have the spacer plate inspected during routine maintenance and replaced as needed.
