SAA6D102E-2 6738-D0-0072 Diesel Engine Assembly Overview
The SAA6D102E-2 6738-D0-0072 Diesel Engine assembly manufactured by Tatan is a heavy-duty inline 6-cylinder powerplant belonging to our Diesel Engine Assembly classification. Engineered specifically for Komatsu PC220-7 and PC220LC-7 22-ton excavators, replacing your worn engine with a Tatan complete assembly eliminates cylinder scoring blow-by, restores 125 kW (168 HP) high-load digging torque, and cures coolant-oil cross contamination across demanding quarry and excavation applications.
Built strictly to original Komatsu OEM specifications, this diesel engine incorporates induction-hardened forged crankshafts, a 24-valve crossflow cylinder head, an integrated plate-type oil cooler, and a wastegated turbocharger, ensuring 100% direct bolt-on installation with flywheel housings, main hydraulic pumps, and chassis mounts.

SAA6D102E-2 6738-D0-0072 Diesel Engine OEM Diagnostic & Troubleshooting Guide
Use this OEM manual diagnostic guide to troubleshoot SAA6D102E-2 engine symptoms on your Komatsu PC220-7 excavator:
| Hydraulic Symptom | Technical Cause Analysis | Tatan Factory-Grade Solution |
|---|---|---|
| 1. Low oil pressure warning (< 0.1 MPa) at hot idle | Excessive crankshaft journal and connecting rod bearing clearance, or worn oil pump gerotor teeth losing oil delivery volume. | Replace with Tatan 6738-D0-0072 complete engine assembly with induction-hardened journals maintaining > 0.35 MPa hot pressure. |
| 2. White steam & coolant boiling from expansion tank | Combustion gas blown past cylinder head gasket between cylinders 5 and 6 due to thermal concentration on rear cylinders. | Install Tatan new engine with factory-torqued MLS head gasket and precision surface-milled parent block face. |
| 3. Excessive blue-gray smoke & oil blow-by from breather tube | Dry parent-bore cylinder wall micro-scoring or broken top compression rings allowing high-pressure combustion blow-by into oil pan. | Install Tatan new SAA6D102E-2 diesel engine; flush intercooler piping and replace primary air intake filter elements. |
| 4. Sluggish engine bogging & black smoke under hydraulic load | Wastegated turbocharger turbine shaft seizure or dirty fuel injection nozzle tips causing incomplete diesel combustion. | Inspect turbo boost pressure, verify in-line injection pump timing, or drop in complete replacement turnkey engine assembly. |
