FA20 Engine Line Boring Service

With the growing popularity of FA20 engines, we've identified a recurring issue similar to what we see in EJ engines: misaligned main bearing bores. This misalignment can lead to a loss of oil pressure, resulting in spun rod and main bearings. To address this, our FA20 Engine Line Boring Service offers a precise solution to correct the main bearing housing alignment and ensure optimal engine performance.

Service Features:

• Precise Material Removal: We begin by removing 0.04-0.08 mm of material from each case half. This step is crucial for achieving proper alignment in the subsequent steps.

• Case Halves Bolting: After the initial material removal, we bolt the case halves together, ensuring that they are securely positioned for the line boring process.

• High-Precision CNC Alignment: The case is then loaded into our CNC machine, where it is carefully leveled out to a tolerance of 5 microns, ensuring top-to-bottom precision against the CNC spindle axis.

• Precision Line Boring: The final line boring is performed within a precision of 5 microns, targeting the minimal recommended bore size to achieve the best possible bearing crush. This step is essential for ensuring that your engine operates smoothly and efficiently.

• Ready for Assembly: Once the line boring process is completed, the FA20 engine case is ready for assembly, with the corrected bearing alignment providing a solid foundation for reliable engine performance.

Complementary Services:

This service is often combined with other offerings such as our FA20 Engine Closed Decking Service, which further enhances engine performance by providing additional cylinder support.

Comprehensive Support:

We offer full service including pickup and re-delivery of your engine case after the chosen engineering processes are completed. Your engine case will be ready for immediate assembly, or you can choose to have it assembled by our professional team.
