Product introduction
This Cummins piston ring compressor is designed specifically for heavy-duty engines, compatible with 6.7L ISX 020 pistons and matching 4955975CQ-20 piston rings, providing high-precision installation support. The Cummins ISX piston ring compressor features a modular design, ensuring a perfect seal between the piston rings and the cylinder block, significantly reducing oil consumption and extending engine overhaul intervals to 1.6 million kilometers. The 4955975CQ-20 piston rings feature an alloy cast iron base with molybdenum-plated/chrome-plated surface treatment, and an optimized oil distribution groove structure, making them suitable for high-load conditions such as those found in mining truck diesel engines.

Product Advantages
The 6.7 cummins 020 piston perfectly matches the cylinder block, with zero damage during installation and a 30% improvement in sealing. It supports 1800 bar high-pressure common rail systems, is heat-resistant, and provides stable power, perfectly compatible with the 6.7L ISX 020 piston. Furthermore, the ISX piston ring compressor has evolved from a high-top ring position to a low-top ring position. Measuring the distance from the piston top to the top of the top ring groove, the high-top ring is approximately 8 mm, and the low-top ring is approximately 11 mm. The low-top ring design, matched with APR bushings, helps to lower the piston top ring position.
FAQ
Q: 1. What is the core function of the Cummins piston ring compressor (model 4918898)?
