Product Details

Product Overview

This high-quality engine bearing set is specifically designed for the Nissan NE6T diesel engine, a powerplant commonly found in heavy-duty industrial, agricultural, and construction machinery. The set includes both main bearings and connecting rod bearings, providing the critical components needed for a complete engine overhaul or rebuild.

The set comprises two key OEM reference numbers: 12213-Z5500 for the connecting rod bearing and 12117-Z5560 for the main bearing. These precision components are manufactured to OEM size standards, ensuring a direct replacement fit for your engine without the need for modifications. Sourced from, these bearings are engineered to restore your Nissan NE6T engine to its original performance specifications.

Please verify your engine model and existing part numbers against the information provided to ensure correct fitment for your specific application, whether it be a generator set, marine vessel, or heavy equipment.

Key Features & Benefits

• OEM Specification Fit: Manufactured to the exact OEM size (12213-Z5500 / 12117-Z5560) for a direct, hassle-free installation without the need for machining or modifications.
• Durable Tri-Metal Construction: Engineered with a robust tri-metal layer (typically steel backing + copper-lead intermediate + overlay) to withstand high loads, high temperatures, and the demanding conditions of diesel combustion.
• Fatigue Resistance: Designed to resist fatigue and deformation under the high cylinder pressures of the NE6T turbocharged diesel engine, ensuring long service life.
• Enhanced Oil Retention: Precision-machined oil grooves and chamfers ensure optimal oil film distribution, providing reliable lubrication to the crankshaft and connecting rod journals even under heavy load.
• Comprehensive Overhaul Kit Component: This set provides both main and rod bearings, simplifying the parts ordering process for a complete engine rebuild.
• Rigorous Quality Control: Each bearing undergoes strict dimensional and material composition testing to guarantee consistent performance and reliability.

FAQ

Q: How do I confirm if these bearings are the correct size for my NE6T engine?
A: You must verify the part numbers stamped on your existing bearings. The connecting rod bearing will be marked 12213-Z5500 and the main bearing will be marked 12117-Z5560. If your engine uses different numbers, this set may not be a direct fit. We always recommend comparing with your old parts before ordering.

Q: Are these standard size or undersized bearings?
A: These bearings are OEM Standard Size. They are designed for a crankshaft that is within factory specifications. If your crankshaft has been ground to an undersize (e.g., 0.25mm, 0.50mm), you will need corresponding undersized bearings. Always measure your crankshaft journals to confirm.

Q: What is the proper installation procedure for these bearings?
A: Installation should be performed by a qualified diesel mechanic. Key steps include: 1) Thoroughly cleaning the bearing bore and crankshaft journals. 2) Applying clean engine oil to the bearing surface. 3) Ensuring the bearing tang fits correctly into the locating groove in the rod or main cap. 4) Torquing the bolts to the manufacturer’s specification using a torque wrench. Never mix old and new bearings or reuse old bolts if specified by the engine manual.
