Complete Guide to Overhaul for Guascor Engines

Preventive maintenance is the core of any efficient cogeneration plant. When a gas engine reaches the operating hour limit stipulated by the manufacturer, performing an Overhaul is not just a recommendation; it is a critical necessity to avoid catastrophic failures and unplanned shutdowns.

At RS Motor, we specialize in the maintenance and supply of spare parts for cogeneration engines. In this complete guide, we break down everything you need to know about the Overhaul of Guascor engines, highlighting our expertise in the most common models on the market: Guascor 180, Guascor 240, Guascor 360, and Guascor 480.

What is an Overhaul on a Guascor Cogeneration Engine?

An Overhaul, also known as a major revision or Rebuild, is an exhaustive maintenance process that returns the engine to its factory specifications and tolerances (“Zero-Hour” conditions).

Unlike routine maintenance, it involves the complete disassembly of the engine block, the thorough inspection of all its internal components and wear elements, and their replacement with genuine or OEM spare parts. Furthermore, at RS Motor, we offer the possibility of using parts reconditioned by us when replacing components. The final objective is to extend the engine’s lifecycle, optimize performance, and ensure maximum availability at the lowest possible cost.

When is an Overhaul necessary? Maintenance Intervals

Guascor engines follow a strict maintenance plan based on operating hours. Although the exact schedule may vary depending on operating conditions, the important maintenance services are classified as follows:

1. Top-End Maintenance: Type R1

Deep maintenance of the top section (cylinder heads). During this intervention, extensive work is carried out on the upper part of the engine.

• Main Actions: Cylinder head reconditioning, turbocharger inspection, and inspection of liners and pistons.

2. Type R2 Maintenance

R2 maintenance includes all the usual tasks performed during an R1 maintenance, but also incorporates additional, more extensive actions. Among these, the replacement of the alternative trains stands out.

3. Major Overhaul: Type R3 Maintenance

The largest preventive maintenance to be carried out on Guascor gas engines is the Type R3 maintenance. Commonly, this type of preventive maintenance is performed every 50,000 approximate operating hours.

The Step-by-Step Overhaul Process at RS Motor

Our technical expertise allows us to execute Overhauls guaranteeing maximum reliability. One of our greatest added values is agility: the execution time of work in RS Motor’s facilities to completely finish an R3 in shorter periods than in the official service. This is our action protocol:

1. Integral Disassembly and Cleaning: Complete stripping of the engine. Critical components undergo deep cleaning by ultrasound and brushing.
2. Inspection and Non-Destructive Testing (NDT): Strict verification of the condition of the engine block, crankshaft, and camshaft, detecting possible micro-cracks.
3. Machining and Reconditioning: Possible reconditioning of the block, if necessary, cylinder heads, and alternator.
4. Assembly with Original/OEM Spare Parts: Assembly following the manufacturer’s torque specifications using original/OEM spare parts.
5. “Zero-Hour” Finish: We perform a complete painting of the engine to protect it from corrosion and deliver it with a factory visual appearance.
6. Testing (Test Run) and Start-up: After assembly, the starting and running-in are carried out. Key Note: After the initial running-in, we perform an additional short-range maintenance (oil and filter change) to ensure success.
