Short Block Remanufacturing Process

Short Block Remanufacturing Process

Each short block begins with complete disassembly and thorough cleaning. The engine block is then honed to factory specifications to ensure proper piston ring seating during break-in. In certain assemblies, oversized pistons may be required. Verado Source manufactures proprietary oversized pistons for select models when needed.

All deck surfaces are carefully cleaned and inspected for corrosion and flatness. This step is especially critical for Verado engines, as they are prone to deck warping. The crankshaft is micro-polished and measured for straightness and concentricity. All main and rod journals are inspected before the block is measured to establish precise bearing clearances.

Bearing clearances are set to factory specifications and verified multiple times to ensure proper fitment and accuracy. Connecting rods are cleaned, inspected for size and flatness, and fitted with new rod bearings. Pistons undergo sonic cleaning and dimensional inspection; any piston found to be out of specification is replaced. Remanufactured pistons are then fitted with new piston rings.

Assembly begins with installation of the freshly cleaned and polished crankshaft into the block, followed by installation of the remanufactured pistons. New 14-block damper seals and a new top seal are installed. Connecting rods are torqued to factory specifications.

OEM gasket sealer is applied to the block mating surfaces, and the second half of the block is installed and torqued to specification. At this point, the short block assembly is complete and ready for the next stage of the build process.
