49182-06010 Turbocharger TD13 for MITSUBISHI S6R / S12R / S16R Diesel Engines

Structural Features and Advantages

The 49182-06010, commonly referred to as the TD13 turbocharger, is a high-performance, heavy-duty forced induction unit engineered to cover Mitsubishi’s most popular large-bore engine families: the S6R (6-cylinder), S12R (12-cylinder), and S16R (16-cylinder). Structurally, it features a single large-volute turbine housing with an optimized A/R (area/radius) ratio of 32, which balances low-end response and high-end flow capacity. The compressor side uses a large-diameter billet compressor wheel with splitter blades (a “mixed-flow” design) to reduce inertia while maintaining high pressure ratios. Unlike smaller turbochargers, the TD13 incorporates a water-cooled bearing housing (optional, but standard on most marine and high-load versions), which prevents coking of the engine oil during hot shutdowns. Key advantages include exceptional airflow capacity (up to 0.78 kg/s), compatibility with both in-line and Vee engines across a wide displacement range (14 to 65 liters), and a cartridge-style rotating assembly that can be replaced without disturbing the engine’s exhaust or intake plumbing. The TD13’s robust cast iron housing with reinforced ribbing resists cracking under thermal cycling, making it a preferred choice for continuous-duty generator sets and marine propulsion.

Core Working Principle

The TD13 turbocharger operates on the constant-pressure turbocharging principle with pulse tuning optimization. Exhaust gases from all cylinders of the S6R, S12R, or S16R engine collect into a common large-diameter manifold before entering the single volute of the turbine housing. While this reduces peak pulse energy compared to twin-scroll designs, it delivers smoother and more consistent turbine inlet pressure, which is ideal for engines that operate at steady loads for long periods (e.g., generator sets). The expanded gas spins the turbine wheel at speeds up to 78,000 RPM, driving the compressor wheel that draws in ambient air through a heavy-duty air cleaner. The compressed air is forced through a charge air cooler (aftercooler) to increase density before entering the engine’s intake plenum. A pneumatic bypass valve (wastegate) is integrated into the turbine housing, calibrated to open at 2.4 bar absolute boost pressure, protecting both the turbocharger and engine from overboost conditions. Because the TD13 is sized for the largest S16R engine, running it on an S6R engine results in very low turbo lag and excellent part-load efficiency, making it a versatile single part number for fleets with mixed engine sizes.

Main Application Equipment

The 49182-06010 TD13 turbocharger is widely used on Mitsubishi S6R, S12R, and S16R engines across multiple industries:

• Prime and standby generator sets (250 kW to 1500 kW) in data centers, hospitals, manufacturing plants, and offshore platforms.

• Marine main propulsion for large tugboats, anchor handling vessels, offshore supply vessels (OSV), and coastal cargo ships.

• Marine auxiliary engines providing onboard power for larger vessels.

• Heavy mining equipment such as large haul trucks (with S16R engines), rock drills, and dewatering pumps.

• Railway traction for heavy-haul locomotives and track maintenance machines.

• Gas compression stations driving natural gas compressors in pipeline networks.

• Irrigation and flood control – large pumping stations with S12R or S16R engines operating 24/7 during harvest or monsoon seasons.

Because the TD13 turbocharger covers three different engine families, it is a popular common spare part for operators who maintain a mixed fleet of Mitsubishi S-series diesels.

Common Failure Symptoms & Repair/Replacement Guidelines

Failure symptoms specific to the 49182-06010 TD13 on S6R, S12R, or S16R engines:

• Slow spool-up and black smoke at low RPM – Indicates a sticking wastegate (common on TD13) or carbon deposits on the turbine nozzle ring.

• Whining or high-pitched screech – Suggests compressor wheel contact with the housing due to thrust bearing wear or foreign object ingression.

• Oil leaks from the bearing housing center section – Oil visible on the outside of the turbo or inside the compressor outlet pipe; often caused by clogged oil drain or worn seal rings.

• Excessive axial shaft play – More than 0.5 mm axial movement indicates failed thrust bearing; radial play beyond 0.8 mm indicates floating bearing wear.

• Low maximum boost – Cannot reach rated boost (typically 2.1–2.3 bar relative on S16R) even with wastegate adjusted; turbine wheel may have eroded tips.

Repair and replacement points:

• Before removing, mark the orientation of turbine housing to bearing housing, as the TD13 has a specific clocking position for oil drain and water lines (if water-cooled).

• Always inspect the wastegate valve seat – a pitted or warped seat causes boost leakage; replace the turbine housing if severely damaged.

• Use only OE-spec or better cartridge assembly (CHRA) for 49182-06010. Do not attempt to replace individual bearings without dynamic balancing.

• Replace all soft parts: oil supply line gaskets, drain flange gasket, V-band clamp (if equipped), and water line O-rings for cooled versions.

• After installation, pre-lubricate the turbo by filling the oil inlet with clean engine oil while rotating the turbine wheel by hand.

• For initial start: crank with fuel off until oil pressure registers, then idle for 5 minutes before applying load. On S16R engines, perform a gradual load ramp (25% steps every 10 minutes) to ensure proper thermal expansion.

• Torque the turbo mounting nuts to 45–50 Nm (use new lock nuts). Re-torque after first heat cycle.
