Isuzu c240 liner

When sourcing the Isuzu C240 liner, you must prioritize material composition and dimensional accuracy. Ensure the liner is made of high-boron cast iron or alloy cast iron to provide excellent wear resistance and heat dissipation. Key dimensions to verify include the inner diameter (86mm standard), outer diameter, and total length, with a tolerance level strictly adhering to OEM standards (typically ±0.02mm). Additionally, check for a honing pattern (cross-hatch) on the inner wall, which is essential for oil retention and piston ring lubrication.

The Isuzu C240 engine is widely used in forklifts (such as TCM, Heli, and Hyster) and stationary generators. You must confirm whether the liner is a 'Finished' (ready-to-install) or 'Semi-finished' (requires boring after installation) type. For B2B buyers, Finished liners are preferred for quick maintenance, but you must provide the supplier with the engine serial number or the specific equipment brand to ensure the flange height and thickness match the engine block's counterbore.

Reliable suppliers should hold ISO 9001 or IATF 16949 certifications, which are the gold standards for automotive and engine component manufacturing. Request Material Test Reports (MTR) to verify the hardness levels (typically HB170-240) and surface roughness (Ra 0.4-0.8μm). For international trade, ensure the products comply with GB/T 1150-2010 (Chinese national standard for internal combustion engines) or equivalent international benchmarks.

The biggest risks are material fraud and shipping damage. Some low-cost suppliers may use ordinary grey cast iron instead of alloyed iron, leading to premature engine failure. To mitigate this, use Made-in-China.com's Secured Trading services to ensure payment is only released after quality verification. Furthermore, because liners are brittle, ensure the supplier uses individual VCI (Volatile Corrosion Inhibitor) packaging and reinforced wooden crates to prevent rust and cracking during sea freight.

Focus on the Total Cost of Ownership (TCO) rather than just the unit price. Negotiate for tiered pricing (e.g., discounts at 100, 500, and 1000 units) and ask for free samples for metallurgical testing. Professional buyers on Made-in-China.com often negotiate for a 12-month warranty or a 1% spare parts allowance to cover potential defects found during assembly.

Cylinder liners are heavy and dense, making Sea Freight (LCL or FCL) the most economical choice. Ensure the supplier provides an accurate HS Code (typically 8409.91 or 8409.99) to avoid customs delays. If shipping to regions with strict import regulations, verify if a Certificate of Origin (CO) or an SGS/Intertek pre-shipment inspection is required to facilitate smooth customs clearance and potential tariff exemptions.
