Major Overhaul of the 1A-9DG Diesel Generator

We offer major overhaul services for the 1A-9DG diesel generator!

Does your locomotive need a power unit upgrade? We provide major overhaul and restoration (KRP-1) of 1A-9DG diesel generators — reliable and efficient units built on the basis of the 16ChN 26/26 (5D49) diesel engine and the GS-501A traction generator. These are installed on locomotives of the 2TE10, 2TE116 series, and their modifications.

What you get after the overhaul:

• Power: Restoration of nominal power up to 2250 kW.
• Efficiency: Fuel consumption reduced by 15–16% and oil consumption by 1.9–2.8 times compared to outdated models (e.g., 10D100).
• Reliability: Extended intervals between repairs thanks to modernized components.
• Eco-friendliness: Compliance with GOST standards for exhaust toxicity, smoke, and noise levels.
• Durability: Full resource restoration with a quality guarantee.

Our services include:

• Disassembly, defect identification, and replacement of worn parts (turbocharger, exhaust manifolds, cooling system).
• Repair and tuning of the diesel engine and generator on a shared frame with a plate coupling.
• Bench testing to confirm operational performance.
• Installation on the locomotive and commissioning works.
