Product Details

Product Overview

This comprehensive Cylinder Liner Kit is a precision-engineered assembly designed for Nissan SD22, SD23, and SD25 diesel engines. The kit includes the cylinder liner (Part No. 11012-L2002), a complete piston set (Part No. 12010-T6202), and piston rings (Part No. 12033-DY230). It is a critical maintenance component for overhauls and rebuilds, ensuring the engine’s combustion chamber maintains proper compression and oil control.

Manufactured under strict quality controls by, this kit is suitable for a wide range of heavy-duty applications, including construction machinery, industrial equipment, agricultural tractors, generator sets, marine engines, and material handling equipment. While primarily designed for the Nissan SD series, it is commonly used in various Japanese industrial and automotive diesel engines that share these platform specifications.

Key Features & Benefits

• Complete Kit Solution: Includes all three critical components (liner, piston, rings) for a single-source, hassle-free engine rebuild. Eliminates compatibility issues between mismatched parts.
• OEM-Grade Fitment: Manufactured to exact OEM specifications (11012-L2002, 12010-T6202, 12033-DY230), ensuring a direct, drop-in replacement without modification. This guarantees proper piston-to-liner clearance and ring end-gap.
• Durable Cast Iron Construction: The cylinder liners are made from high-quality alloy cast iron with a hardened bore surface, providing exceptional wear resistance against the piston rings and reducing oil consumption over the engine’s service life.
• Advanced Ring Pack: The piston ring set typically includes a combination of compression rings and an oil control ring, designed to optimize gas sealing and lubricant management, which is critical for maintaining engine power and reducing emissions.
• Rigorous Quality Control: Each kit undergoes outgoing video inspection and comprehensive machinery test reports, ensuring dimensional accuracy and material integrity before shipment.
• Versatile Application: Suitable for high-hour engines in construction (excavators, loaders), agriculture (tractors, harvesters), industrial pumps, and marine auxiliary power units.

Technical Specifications

OEM Cross-Reference

This kit is a direct replacement for the following original Nissan part numbers. Please verify your engine block stamping for exact model matching.

• Cylinder Liner: 11012-L2002
• Piston Set: 12010-T6202
• Piston Ring Set: 12033-DY230

These numbers are widely used across the Nissan SD engine family. If your existing parts show different suffixes (e.g., -L2001 or -T6201), please consult our technical team for cross-verification, as minor dimensional variations may exist in older production runs.

Compatibility

This Cylinder Liner Kit is specifically engineered for the Nissan SD22, SD23, and SD25 diesel engines. Based on industry standard applications, it is commonly used for:

• Construction Equipment: Excavators, Bulldozers, Wheel Loaders (e.g., Komatsu D20/D21 series with Nissan SD engine swaps, or Nissan UD trucks).
• Industrial Machinery: Forklifts, Air Compressors, and Generator Sets (Genset) powered by these engine models.
• Agricultural Tractors: Nissan and other Japanese brand tractors from the 1980s-1990s utilizing SD series power units.
• Marine Applications: Auxiliary engines and small marine propulsion units.

Important Fitment Note: While this kit is dimensionally correct for the engines listed, we strongly recommend comparing your existing components to the part numbers above. We do not have verified year-range data for all chassis applications.

FAQ

Q: How do I confirm this kit fits my specific engine?
A: First, check the engine model number stamped on the engine block (look for “SD22”, “SD23”, or “SD25”). Second, remove one existing cylinder liner and piston assembly. Match the part numbers stamped on the old liner (11012-L2002) and piston (12010-T6202). If your numbers match, the kit is a direct fit. If you have a different suffix, contact us with a photo of the old part numbers for cross-reference.

Q: What is the recommended installation procedure for these liners?
A: These are typically dry liners (no coolant contact). Ensure the cylinder block bore is clean and free of debris. Apply a thin film of clean engine oil to the liner’s outer surface. Use a liner press tool to gently press the liner into the block. Never hammer the liner directly. After installation, verify the liner protrusion above the block deck is within the engine’s service manual specification (typically 0.02-0.10 mm). Install new piston rings with gaps staggered 120 degrees apart.

Q: What is the normal service life of this kit under standard operating conditions?
A: With proper maintenance (clean oil, air, and fuel), this OEM-quality kit can provide 5,000 to 8,000 operating hours in industrial or agricultural applications. In marine or heavy construction environments with higher loads and dust, the service interval may be shorter. We recommend inspecting the cylinder bore for wear and piston ring end-gap at every major engine overhaul interval specified by the original equipment manufacturer.
