What This Komatsu D375A-6R Parts Book Contains

This is the complete illustrated parts catalog for the Komatsu D375A-6R bulldozer, covering machines from serial number 65001 and up and the SAA6D170E-5EE engine from serial 610984 and up. Every assembly is presented as an exploded-view diagram with a matching parts table that lists the index number, Komatsu part number, description, quantity, and — where applicable — the serial number range the part applies to. This structure lets you identify the exact part you need without guesswork, whether you are ordering a single seal or rebuilding a complete assembly.

Engine Assembly

The engine section breaks down the SAA6D170E-5EE into its major subassemblies: cylinder head with valve inserts, guides and springs; cylinder block with liners, main bearing caps and piston cooling nozzles; crankshaft with main and thrust metal options in standard and undersize dimensions; camshaft with gear and thrust plate; pistons with rings, pins and connecting rods; flywheel and ring gear; oil pan with suction tube and gauge; crank pulley; and vibration damper. Each diagram is keyed to a parts table with precise quantities, so you can verify what fits your serial number before ordering.
