4d30g31 Cylinder Liner Kit 495b-01005b Piston Set 495b-04001 495b-04001-1a Ring 490b-04100 For Xinchai Diesel Engine Parts

Product Overview

This comprehensive Cylinder Liner Kit is a precision-engineered component set specifically designed for the Xinchai 4D30G31 diesel engine. It includes the cylinder liner (part number 495B-01005B), piston set (part numbers 495B-04001 & 495B-04001-1A), and piston ring set (part number 490B-04100). This kit is an ideal replacement solution for overhauling or rebuilding Xinchai 4D30G31 engines commonly found in construction machinery, agricultural equipment, industrial generators, and marine applications.

Manufactured to OEM size specifications, this kit ensures a precise fit and reliable performance. While primarily designed for the Xinchai 4D30G31, it is commonly used as a direct replacement for engines in various Chinese-manufactured heavy equipment. The components are built to restore engine compression, reduce oil consumption, and extend service life, making them a cost-effective alternative to OEM parts.

FAQ

Q1: Is this kit a direct fit for my Xinchai 4D30G31 engine?
A: Yes, this kit is specifically designed for the Xinchai 4D30G31 diesel engine. The components are manufactured to OEM size specifications (495B-01005B, 495B-04001, etc.), ensuring a direct, bolt-in fit. However, we always recommend verifying your engine model and existing part numbers before ordering.

Q2: What is included in this cylinder liner kit?
A: The kit includes one cylinder liner (495B-01005B), one piston set (consisting of 495B-04001 and 495B-04001-1A), and one piston ring set (490B-04100). This provides all the core components needed for a single-cylinder overhaul.

Q3: Can I install these parts myself, or do I need specialized tools?
A: While the kit is designed for straightforward replacement, proper installation requires mechanical expertise and standard engine overhaul tools (e.g., ring compressor, liner puller). For best results, we recommend installation by a qualified diesel mechanic. Proper torque specs and assembly procedures should be followed.
