FILM-STRIPE 9X2803 - Caterpillar

The 4.5" bore, V8 (Direct Injection) Engine can be reconditioned to provide performance characteristics comparable to a new engine. The reconditioned engine will operate satisfactorily if certain reconditioning precautions are observed.Performance and oil control comparable to a new engine can be obtained only if the necessary machining is done to the required Specifications. Cylinder block reconditioning requires an automatic honing machine to control size, surface finish, and crosshatch pattern of the cylinder bores. A manually operated hone does not give satisfactory results and is not recommended.To facilitate reconditioning, pistons and rings are available .020 in. (0.51 mm) and .040 in. (1.02 mm) oversize.Connecting rod and main bearings are available .010 in. (0.25 mm), .020 in. (0.51 mm) and .050 in. (1.27 mm) undersize.Main bearings are available with a .010 in. (0.25 mm) oversize outside diameter. These bearings are for cylinder blocks that have had the bore for the main bearings bored oversize.
