4D94E Cylinder Block
Tailor-made for Komatsu engines, it perfectly matches the working conditions of Komatsu models. The one-piece molding process creates a sturdy structure, featuring high temperature resistance and impact resistance, which effectively avoids deformation risks after long-term use. The precision-machined sealing grooves prevent oil leakage, enabling efficient power transmission while balancing durability and fuel economy.
Product Description
- The Komatsu cylinder block fits PC200-8, PC360-7 excavators and WA380 loaders, compatible with core engines SAA6D107E and SAA6D114E. It is made of high-strength wear-resistant alloy cast iron (tensile strength ≥550MPa), with key dimensions meeting IT7 grade: the cylinder bore cylindricity error is ≤0.006mm, the main bearing bore coaxiality is ≤0.012mm, and both have a tolerance of ±0.01mm.
Product Advantages
It undergoes ultrasonic flaw detection (no internal defects), a 2.5MPa water pressure test (holding pressure for 15 minutes without leakage) and high-temperature wear resistance testing, featuring resistance to heavy-load impact and a 60% longer service life. It enables precise adaptation per OE standards to reduce installation and debugging time, and is compatible with multiple models of construction machinery, solving accessory matching issues.
