SAA6D114E-2 6743-01-1100 Engine Assembly Overview
The SAA6D114E-2 6743-01-1100 Engine assembly manufactured by Tatan is a heavy-duty inline 6-cylinder, 8.27-liter industrial diesel powerplant belonging to our Diesel Engine Assembly classification. Engineered specifically for Komatsu PC300-7, PC300LC-7, and PC300HD-7 30-ton excavators, replacing your failed or worn engine with a Tatan complete assembly eliminates cylinder liner cavitation, restores 184 kW (247 HP) high-load rock-trenching torque, and cures coolant-oil cross contamination across demanding quarry and mining applications.
Driving the excavator’s HPV165 hydraulic pump and distributing fluid through the PC300-7 main control valve, this complete diesel engine incorporates an induction-hardened forged crankshaft, replaceable wet cylinder sleeves, an upgraded plate oil cooler pack, and a wastegated turbocharger, ensuring 100% direct bolt-on installation with flywheel housings and chassis mounts.

Supported Excavator Machinery Brands & Powertrain Lineup
In addition to Komatsu, Tatan manufactures replacement complete diesel engines, cylinder blocks, and overhaul components for major excavator brands:
30-Ton Heavy Mining Powertrain Supply & Multi-Brand Fleet Reliability
Operating high-hour 30-ton excavators under tough quarry conditions demands rugged powertrain engineering. Tatan provides heavy-duty complete diesel engines, water pumps, oil coolers, and crankshafts tailored for mixed fleets across Volvo, Komatsu, CAT, Cummins, and John Deere equipment:
🛡️ Anti-Cavitation Wet Liners
Centrifugally cast alloy iron wet sleeves prevent vibration pitting and eliminate coolant leakage into the oil pan.
🔥 Reinforced Cylinder Head
High-tensile alloy iron heads with reinforced valve bridges resist thermal cracking during continuous 184 kW heavy quarry loading.
🛢️ High-Flow Lube System
Heavy-duty oil pump delivers continuous high oil volume, maintaining hot oil pressure above 0.38 MPa across all main journals.
Application Scenarios & Buyer Value
When upgrading or replacing your 30-ton excavator powerplant with our SAA6D114E-2 6743-01-1100 Engine, buyers achieve maximum operational uptime and flow control:
| Application Scenario | Value Delivered to Buyer |
|---|---|
| Komatsu PC300-7 Engine Replacement | 1:1 direct bolt-on installation eliminates cylinder blow-by and restores 184 kW power for simultaneous boom, arm, and swing speeds. |
| Hydraulic Overhaul Workshops | Avoids the complex labor of block line-boring and fuel pump timing; saves mechanic hours with a pre-timed, dyno-tested unit. |
| Mining & Quarry Fleet Operations | Reinforced forged pistons and multi-layer steel head gasket withstand continuous heavy rock-breaker hammer operations. |
| Heavy Equipment Parts Stockists | Fast-moving, high-demand 30-ton engine inventory ready for immediate shipment to minimize customer downtime. |
SAA6D114E-2 6743-01-1100 Engine OEM Diagnostic & Troubleshooting Guide
Use this OEM manual diagnostic guide to troubleshoot SAA6D114E-2 engine symptoms on your Komatsu PC300-7 excavator:
| Hydraulic Symptom | Technical Cause Analysis | Tatan Factory-Grade Solution |
|---|---|---|
| 1. Engine oil turns milky & oil level rises | Wet cylinder liner lower O-ring degradation or cavitation erosion pitting through the liner wall, allowing coolant into the oil pan. | Replace with Tatan 6743-01-1100 complete engine assembly fitted with brand-new cavitation-resistant wet sleeves and viton seals. |
| 2. Low oil pressure warning (< 0.12 MPa) at hot idle | Excessive crankshaft journal and connecting rod bearing clearance, or worn oil pump gears losing delivery volume under 184 kW heat. | Install Tatan new engine with induction-hardened forged journals maintaining > 0.38 MPa hot running pressure. |
| 3. Excessive blue-gray smoke & oil blow-by from breather tube | Piston top ring groove wear or broken chrome-faced compression rings allowing combustion gas blow-by into the crankcase. | Install Tatan new SAA6D114E-2 diesel engine; flush intercooler piping and replace primary air intake filter elements. |
| 4. Sluggish engine bogging & black smoke under 1.8 m³ bucket load | Wastegated turbocharger shaft drag or in-line injection pump governor timing slip causing low boost pressure (< 180 kPa). | Inspect turbo boost pressure, verify injection timing, or drop in complete replacement turnkey engine assembly. |
Transport Packaging & Certified Manufacturing Standards
Complete diesel engines require absolute vibration and moisture isolation. Every Tatan PC300-7 engine undergoes anti-corrosion fogging, heat-sealed plastic wrap, and solid timber export crating:
