Heavy-duty diesel engine blocks often need counterboring during repair or if they have been overhauled. Typically the engine block and wet liners develop a leak and the counterbore seats in the engine block which require them to be resurfaced during an engine overhaul. The team at The Service Company is skilled in utilizing precision machining equipment to ensure a proper engine counterbore on your heavy-duty truck. Our focus is to provide accurate machining facilities and service in order to reduce your downtime and increase your vehicle's longevity.

The main purpose of cylinder liner or sleeve protrusion in your diesel engine is to give you the proper amount of “crush” on your cylinder head gasket. This ensures that once torqued, your cylinder head crushes the gasket evenly and to the correct specification. Counterboring ensures that the cylinder liner is properly sealed in order to prevent the antifreeze from entering the oil pan.
This requires counterbore cutter plates and a very accurate counterbore-machining unit that can be centered automatically and uses electromagnets to clamp in place. Proper counterboring requires an extensive amount of training and experience.
