This Caterpillar Engine Kit is FP Diesel Brand. FP Diesel, part of the Federal-Mogul engine systems group, is the leading brand of premium heavy duty engine parts and gaskets. Today's heavy duty market demands performance. At FP Diesel, performance means more than just providing quality parts at competitive prices. Performance means precision engineered parts that meet your demanding specifications. FP Diesel brand parts carry a unprecedented 2 year warranty.

All cylinder blocks must be precisely checked for concentricity and deck surface condition prior to liner installation. Anything less than perfect condition at these points can lead to cracked flanges on the cylinder liner. Failure to thoroughly inspect these two areas is the leading cause of liner flange cracking and should be the foremost consideration if liner flange failure occurs. FP Diesel warranty claims will not be considered without sufficent evidence on the cylinder blocks condition.

Please refer to Caterpillar repair procedure (SEHS9564-1) for inspecting your liner protrusion and cylinder block deck.
