SAA6D107E-1 6754-01-1100 Engine Assembly Overview
The SAA6D107E-1 6754-01-1100 Engine assembly manufactured by Tatan is a heavy-duty inline 6-cylinder high-pressure common rail (HPCR) powerplant belonging to our Diesel Engine Assembly classification. Engineered specifically for Komatsu PC220-8 and PC220LC-8 22-ton excavators, replacing your worn or seized engine with a Tatan turnkey assembly eliminates common-rail starting delays, restores 125 kW (168 HP) high-load digging torque, and cures excessive crankcase blow-by across demanding quarry and excavation applications.
Delivering direct hydraulic drive to the excavator’s HPV95 hydraulic pump and regulated by the PC220-8 main control valve, this complete diesel engine incorporates an induction-hardened forged crankshaft, a 24-valve crossflow cylinder head, an upgraded plate oil cooler pack, and a wastegated turbocharger, ensuring 100% direct bolt-on installation with flywheel housings and chassis mounts.

SAA6D107E-1 6754-01-1100 Engine OEM Diagnostic & Troubleshooting Guide
Use this OEM manual diagnostic guide to troubleshoot SAA6D107E-1 common-rail engine symptoms on your Komatsu PC220-8 excavator:
| Hydraulic Symptom | Technical Cause Analysis | Tatan Factory-Grade Solution |
|---|---|---|
| 1. Hard starting / long cranking when engine is hot | High-pressure common rail injector control valve internal wear allowing excessive back-leakage, dropping rail pressure below 35 MPa cranking threshold. | Replace with Tatan 6754-01-1100 complete engine assembly fitted with brand-new calibrated Bosch HPCR fuel injection system. |
| 2. Severe engine bogging & black smoke during compound dig | Turbocharger wastegate valve seized or intake air intercooler core cracked, causing low boost pressure (< 170 kPa) and rich fuel burning. | Install Tatan turnkey complete engine; check boost pressure sensor reading and flush intercooler connecting ducting. |
| 3. Heavy crankcase blow-by mist from breather tube | Piston top ring land micro-welding or cylinder wall liner cross-hatch polished away under continuous 125 kW quarry hammer load. | Install Tatan new SAA6D107E-1 engine; flush engine oil galleries and replace primary air intake filter elements. |
| 4. Engine oil milky & coolant level dropping in expansion tank | Plate-type oil cooler core internal element cracking from thermal shock, allowing pressurized engine oil to cross into the cooling circuit. | Install Tatan brand-new engine assembly with factory pressure-tested heavy-duty plate oil cooler and new thermostat pack. |
