Description
SAA6D114E-2 6743-01-1200 Engine Assembly Overview
The SAA6D114E-2 6743-01-1200 Engine assembly manufactured by Tatan is a heavy-duty inline 6-cylinder, 8.27-liter mechanical in-line fuel pump industrial powerplant belonging to our Diesel Engine Assembly classification. Engineered specifically for Komatsu PC360-7 and PC360LC-7 36-ton excavators, replacing your failed or cracked engine with a Tatan complete turnkey assembly eliminates wet-liner cavitation leaks, restores 184 kW (247 HP) continuous rock-trenching power, and cures low hot idle oil pressure across demanding quarry and mining applications.
Driving the excavator’s HPV165 hydraulic pump and distributing high-pressure fluid through the PC360-7 main control valve, this complete diesel engine incorporates an induction-hardened forged steel crankshaft, heavy-wall wet cylinder sleeves, a pre-timed in-line injection pump, 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:
36-Ton Heavy Quarry Powertrain Standards & Industrial Engine Fleet Engineering
Operating high-hour 36-ton production excavators in abrasive rock quarries demands extreme thermal durability and high fuel tolerance. Tatan delivers heavy-duty complete diesel engines engineered with heavy-wall wet sleeves, forged alloy crankshafts, and pre-timed in-line injection systems across international earthmoving fleets:
🛡️ Anti-Cavitation Wet Sleeves
Centrifugally cast alloy iron wet sleeves with reinforced viton packing prevent vibration pitting and coolant contamination into the sump.
🔥 Reinforced Cylinder Head
High-tensile alloy iron heads with reinforced valve bridges resist thermal fatigue cracking under continuous 184 kW full-load digging.
🛢️ High-Flow Lube System
Heavy-duty oil pump delivers continuous high lube volume, maintaining hot oil pressure above 0.38 MPa across all main journals.
Application Scenarios & Buyer Value
When upgrading or replacing your 36-ton excavator powerplant with our SAA6D114E-2 6743-01-1200 Engine, buyers achieve maximum operational uptime and flow control:
| Application Scenario | Value Delivered to Buyer |
|---|---|
| Komatsu PC360-7 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 36-ton engine inventory ready for immediate shipment to minimize customer downtime. |
SAA6D114E-2 6743-01-1200 Engine OEM Diagnostic & Troubleshooting Guide
Use this OEM manual diagnostic guide to troubleshoot SAA6D114E-2 engine symptoms on your Komatsu PC360-7 excavator:
| Hydraulic Symptom | Technical Cause Analysis | Tatan Factory-Grade Solution |
|---|---|---|
| 1. Engine oil turns milky & oil level rises in pan | Wet cylinder liner lower viton O-ring degradation or cavitation pitting eroding through the cylinder sleeve wall, allowing coolant into the oil pan. | Replace with Tatan 6743-01-1200 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 keystone ring groove carbon-welded or broken 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. Heavy black smoke & engine bogging under 1.9 m³ bucket load | In-line mechanical injection pump governor spring fatigue or turbocharger wastegate actuator drag causing boost pressure loss (< 180 kPa). | Inspect turbo boost pressure, verify injection timing, or drop in complete replacement turnkey engine assembly. |
Transport Packaging & Certified Manufacturing Standards
Complete 8.3-liter diesel engines require absolute vibration and moisture isolation. Every Tatan PC360-7 engine undergoes anti-corrosion fogging, heat-sealed plastic wrap, and solid timber export crating:
