331-1682 Direct Injection Engine Block for Caterpillar C7.1

331-1682 C7.1 Cylinder Block Overview

The 331-1682 engine cylinder block is designed for Caterpillar C7.1 inline six-cylinder direct injection diesel engine applications. It provides the main structural housing for the cylinder bores, crankshaft and other major internal engine components.

This cylinder block is applicable to selected Caterpillar 320D2, 320D2 GC, 320D2 L, 323D3 and 324 excavators. Because engine arrangements can differ within the same equipment model, final fitment should be confirmed using the engine serial number, arrangement number and original block part number.

Inspection Before Engine Assembly

Before assembly, clean and inspect the cylinder bores, deck surface, main bearing housing, oil galleries, threaded holes, core plugs and machined mounting faces. Bore dimensions, deck flatness and bearing alignment should be checked according to the applicable C7.1 engine rebuilding specifications.

Engine assembly and measurement should be completed by a qualified diesel engine repair workshop. The old block number, engine identification plate and clear photos can be supplied for additional checking before shipment.
