For 371-5941 3715941 Cylinder liners CAT 3304 3306 Excavator engine parts

Specification

Description

This product is a wet cylinder liner with part number 371-5941 (3715941), specially designed and matched for 3304 & 3306 series excavator diesel engines. It is a core vulnerable power component of the engine cylinder block. Adopting an integrated centrifugal casting structure of alloy cast iron, it comes with honed reticular oil storage patterns on inner wall, multiple sealing ring grooves at the lower end, and complete positioning flange structure at the upper end. It perfectly matches original assembly dimensions and installation tolerances, and can directly replace old parts for engine overhaul and renovation maintenance.

Advantage

Precise original standard size: Part number 371-5941 fully complies with original specifications. No modification or reprocessing is required during installation, with direct fitting and zero clearance.
High-quality alloy material: High-strength gray alloy cast iron with heat quenching treatment, featuring far better crack resistance and deformation resistance than ordinary castings.
Special honed reticular inner wall: Uniform cross oil storage patterns quickly form engine oil film, greatly reducing dry friction wear of piston rings.
Integrated precision machining: Full precision grinding for flange end face, sealing grooves and inner & outer diameters, with stable sealing performance to completely prevent water and air leakage.
System matching design: Matched with piston, piston ring and cylinder gasket in the whole wear system, extending the synchronous service life of whole engine wear parts.

Performance

Wear resistance & durability: The inner wall receives special hardening treatment, enduring high-speed reciprocating friction of piston for a long time. No inner wall scoring, step wear or rapid abrasion in long-term service.
Heat resistance & anti-fatigue performance: Processed by heat treatment aging technology, it maintains stable performance under long-term high temperature and high pressure engine conditions, without deformation, cracking or edge chipping under high heat load.
Stable sealing performance: Multi-channel sealing ring grooves at lower end provide excellent waterproof sealing after assembly, effectively preventing coolant from penetrating into combustion chamber and engine oil water ingress failure.
Power stability performance: High precision cylinder inner diameter ensures stable and sufficient cylinder compression pressure, guaranteeing steady engine power output, standard fuel consumption and smooth idle operation.
Working condition adaptability: Fully adapted to heavy load, dusty and harsh construction site conditions of excavators, meeting high-intensity demands of long-term continuous operation and frequent start-stop work.
