STORK TM410 & TM410C Marine Fuel Injection Pump

Genuine STORK TM410 & TM410C Fuel Injection Pump

The STORK TM410 fuel pump is a high pressure, single cylinder, jerk type injection pump, designed for use with Marine Gas Oil (MGO) and high viscosity Heavy Fuel Oil (HFO) under severe operating conditions. This part is designed to work at normal working crankshaft speeds of 500 to 600 RPM. This atomizes the fuel correctly, reducing exhaust smoke and saving your cylinder liner and piston assembly from premature wear.

The Stork Werkspoor TM410 and TM410C series medium speed four-stroke diesel engines are well known world-wide as workhorses for maritime propulsion, auxiliary power generation and fixed land-based installations. The fuel injection system requires accurate pressure tolerances and perfect timing in order to maintain high thermal efficiency and clean combustion.

Main Features

1. The HFO optimization is designed to accept high viscosity fuel profiles in compliance with ISO 8217:2005(E) and ISO-F-RMH 700 without viscosity induced pressure decreases.
2. This jerk-pump arrangement permits the development of pressure in each cylinder individually, but keeps the performance balanced through the engine block.
3. High Grade Wear Resistance: Specially surface hardened plunger and barrel assemblies are precision machined to decrease the corrosive sulfur content and abrasive cat-fines in heavy fuels.
4. Rigid Monoblock Housing The cast housing is designed to minimize high mechanical stresses at the peak injection pressure periods, therefore reducing external fuel leakage and casing distortion.
5. Provides a seamless fit with the existing timing gear mechanical rollers and low-pressure fuel rail connections to give a drop-in fit. Direct interchangeability. Made to the exact OEM specs.

Marine Engineer Expert’s Insights:

1. Bumping Clearance & Timing Verification: Never assume a direct swap means automatic timing alignment. Always measure and check the fuel pump timing and lead position via the engine flywheel markings. Incorrect indexing alters peak cylinder firing pressures (Pmax), leading to thermal overloading or exhaust smoke.
2. Inspect the Cam Roller Assembly: Don’t just replace the pump casing. Always inspect the driving cam track and the roller guide for pitting or uneven wear patterns. A sticky cam roller will distort the injection profile, causing fuel delivery lag and accelerated wear on your brand-new plunger.
3. HFO Temperature Management: If running on Heavy Fuel Oil, ensure that your fuel system pre-heating temperature is fully stabilized before changing over or loading the engine. Cold HFO causes immense thermal shock and high structural stress inside the pump barrel, which can score the plunger or lead to immediate sticking.
