For several decades, UPC has renovated ALCO marine engine cylinder heads. We have conducted the inspection and reconstruction according to the standards of many major manufacturers. A complete record allows the traceability of the operations in compliance with our ISO 9001 certified quality management system.
To this day, more than 3,000 cylinder heads have passed through our workshops!
UPC performs the counterbore for Detroit Diesel Series 60 and Mercedes engine blocks. For nearly 20 years, our team has counterbored more than 15,000 cylinders in our workshops and throughout Québec.
This operation is required to renovate the engine when the cylinder liner journal has collapsed, causing a loss of tightness with the surface of the cylinder head. For each counterbore, we guarantee the quality and accuracy of the operation to ensure the tightness of the system: cylinder head, gasket, cylinder liner and engine block.
UPC has also counterbored many engines of all sizes!
