Perkins 2674A080 Turbocharger TO4E35 for 1006-6T Diesel Engine

Perkins 2674A080 Turbocharger TO4E35 for 1006-6T Diesel Engines

The Perkins 2674A080 Turbocharger is a finely constructed, heavy duty forced induction system specifically intended for the Perkins 1000 Series (i.e. 1006-6T and 1006-6TW six cylinder turbo diesel engines). The turbocharger is designed on the TO4E35 / GT3267 aerodynamic platform engineered to cope with the severe thermal dynamics and demanding operating conditions of maritime propulsion, auxiliary power generation, large agricultural equipment and industrial prime movers.

The 2674A080 features high-performance nickel-alloy turbine housings and precision balanced cast-aluminum compressor wheels to optimize volumetric efficiency, maximize torque delivery and reduce specific fuel consumption (SFC) through precise wastegate control and aerodynamic profiling to the YB engine build lists.

Main Features

1. The profile of the compressor wheel TO4E35 was custom designed for the volumetric air requirements of the 6.0L 1006-6T engine block and is optimized to avoid compressor surge and exhaust choking.
2. High Thermal Resiliency Premium ductile iron housings are designed to withstand high exhaust gas temperatures (EGT) associated with sustained heavy-duty industrial or marine use.
3. Factory Calibrated Wastegate: Pre-set pneumatic wastegate actuator that prevents over-boost concerns and delivers dependable low-end torque.
4. Dynamic Balancing: Components are micro-dynamically balanced to minimize operating vibrations which greatly increases the service life of internal journal and thrust bearings.
5. Direct OEM Fitment: Manufactured to the same mechanical specifications as the original equipment so they may be attached to existing manifolds and oil lines without modification.

Applications

• Marine Propulsion & Auxiliaries The Perkins YB construction list is ideal for main propulsion arrangements on commercial vessels and continuous-duty marine auxiliary generators.
• Industrial Generator Sets: Used in prime power and standby diesel generator packages for telecom, data center and maritime applications.
• Agricultural Equipment : Used in heavy duty tractors, harvesters and irrigation pumps driven by Perkins 1006-6T engine.
• Construction & Engineering Field: Ideal for earth-moving equipment, material handlers and big industrial pumps serving difficult job sites.

Protocol for Professional Installation & Commissioning

1. Mandatory Oil Priming: Never perform a dry start of a newly fitted turbocharger. Prior to connecting the oil feed line, inject clean certified engine oil straight into the turbocharger’s oil inlet port and rotate the compressor wheel by hand throughout this process. It gives instant lubrication to the journal bearings on first cranking.
2. Flush the Lines: Check and flush the oil feed and drain lines. Over time the heat generates carbon deposits (coking) to block the drain lines. A restricted drain creates crankcase backpressure inside the turbo block, which forces oil past the dynamic seals to spill into the exhaust or compressor housings.
3. Check Intake Integrity – Make that all parts of the air intake system are vacuumed and clear of foreign object debris (FOD) upstream of the compressor. A compressor wheel turns at 100,000+ RPM . Even a tiny bit can wreck one .
4. Cool Down Routine: Operators should idle engine 3 to 5 minutes prior to absolute shutdown after high-load operations. Thermal soak occurs during abrupt shutdowns, where stagnant oil in the turbocharger bearing housing bakes, closing internal oil passageways and causing premature bearing failure.
