4TNE98 Cylinder Block 729902-01560 for Yanmar Engine Parts

Product Details

Product Overview

This is a high-quality Cylinder Block specifically designed for the Yanmar 4TNE98 diesel engine, carrying the genuine part number 729902-01560. As the core structural component of the engine, this cylinder block provides the rigid foundation necessary for reliable combustion and long-term durability. It is engineered to meet OEM size and performance specifications, making it a critical replacement part for engine overhauls and rebuilds.

While fitment is primarily confirmed for the Yanmar 4TNE98 engine model, this block may also be compatible with other engines in the Yanmar TN and TNE series that share the same displacement and mounting architecture. Please verify your existing part number and engine model before installation.

Key Features & Benefits

• OEM-Spec Dimensions: Manufactured to the exact OEM size (729902-01560) to ensure a perfect fit with mating components like the cylinder head, crankshaft, and oil pan.
• Durable Cast Iron Construction: Built from high-grade cast iron to withstand extreme combustion pressures and thermal stress, reducing the risk of cracking or warping.
• Precision Machined Surfaces: All deck surfaces, cylinder bores, and bearing journals are precision-machined to tight tolerances for optimal sealing and reduced friction.
• Direct Replacement: Designed as a direct bolt-on replacement for the original Yanmar part, minimizing installation time and labor costs.
• Comprehensive Quality Control: Each block undergoes rigorous inspection to ensure dimensional accuracy and material integrity before shipment.
• Versatile Application: Suitable for a wide range of heavy-duty applications including construction equipment, agricultural tractors, industrial pumps, marine gensets, and material handling machinery.

FAQ

Q1: Is this cylinder block a direct bolt-on replacement for my Yanmar 4TNE98 engine?
A: Yes, this part (729902-01560) is manufactured to OEM specifications and is designed as a direct replacement for the original Yanmar cylinder block. However, we recommend cross-checking your existing block’s part number and measuring critical dimensions (bore size, deck height, main bearing bore) to ensure compatibility, especially if your engine has been modified or rebuilt previously.

Q2: What additional parts should I replace during a cylinder block replacement?
A: When replacing the cylinder block, it is strongly advised to install new main bearings, thrust washers, cylinder liners (if applicable), piston rings, and a complete gasket set. This ensures proper sealing, oil clearance, and long-term reliability. We also recommend replacing the oil pump and water pump as preventative maintenance.

Q3: How should I prepare the block for installation?
A: Before installation, thoroughly clean the block to remove any protective coating, debris, or machining chips. Inspect all oil passages and water jackets for blockages. Apply a light film of engine oil to cylinder bores and bearing surfaces. Always follow the manufacturer’s torque specifications and tightening sequence for main bearing caps and cylinder head bolts. If you lack experience, professional installation by a qualified diesel mechanic is recommended.
