Perkins 1104A-44TG2 Diesel Engine Assy: Complete Generator Power Unit Ready to Ship

When the backup genset at a mine site, plant or commercial building quits at 2 a.m., the first question is never "what failed" — it's "how fast can we get power back". If the engine itself is worn out, the honest answer is usually: not fast enough. And on 60 kVA to 80 kVA sets, the engine is the part that decides whether your power is stable or just present.

Rebuilding a tired engine in the field means chasing individual internal parts, paying labor to piece it back together, and hoping it holds under prime load once it's on line again. Swapping in a complete factory-assembled engine — cooling package included — is the boring, dependable fix. It costs less in downtime than any other option, and it's the one we recommend.

At SWAFLY MACHINERY CO., LIMITED, we keep high-demand power units in stock so buyers don't have to wait out a factory backorder. Right now we have brand-new, complete Perkins 1104A-44TG2 engine assemblies in the warehouse, each supplied with its radiator water tank package, ready for immediate international dispatch.

Why this engine, for gensets specifically

The 1104A-44TG2 is a 4-cylinder, 4.4-liter turbocharged diesel built for G-Drive (generator set) duty. It's a popular engine for a reason: simple, tough, and it takes load well. For power generation, that matters more than peak numbers.

• Complete power unit, radiator included. Engine block, fuel system, air intake and heavy-duty radiator water tank come as one package. Your technician can set it straight onto the base frame — no hunting down separate cooling parts.
• Mechanical fuel injection. A rotary pump that doesn't care about dirty fuel or dusty air, and doesn't drag an ECM into every fault code. In harsh, off-grid conditions, that simplicity is the feature.
• Steady 50/60Hz output for 60–80 kVA sets. Suitable for standby and prime power gensets, with good fuel economy and low noise.
• Parts you can actually find. Standard Perkins 1100-series engineering means filters, belts and wear parts are stocked almost anywhere in the world — no waiting weeks for an obscure component.

What we check before an engine leaves the warehouse

A complete engine plus radiator is an awkward, high-value shipment. We do this every day, and the checks are deliberately boring:

1. Fit verification first. Our team confirms flywheel size, SAE housing spec, control wiring layout and radiator mounting dimensions against your alternator (generator head) and base frame. 100% compatibility, or we tell you what's off.
2. Sealed against corrosion. Engine and radiator core are fully drained, treated with rust preventive, sealed against dirt and moisture, and wrapped in heavy-duty protective film.
3. Crated for ocean or air freight. The whole package is bolted down inside an export-grade wooden crate — radiator fins and fuel components included, protected for the journey.

A failed genset engine doesn't have to paralyze your operation. Don't rebuild it on hope.
