Std 70mm Engine Piston And Ring Set 119515-22080 For Yanmar 2d70e-5 3tnv70 2ym15 3ym20 Vio15 Mini

Product Details

Product Overview

This is a high-quality Standard Size (STD) 70.00mm Engine Piston and Ring Set, identified by OEM number 119515-22080. Designed as a direct replacement for Yanmar diesel engines, this piston assembly is a critical component for maintaining compression and engine performance in compact machinery.

This kit is engineered for use in the Yanmar 3TNV70, 3D70, and 3D70E engine models. It is commonly utilized in popular mini excavators such as the Yanmar Vio15, as well as marine applications like the Yanmar 2YM15 and 3YM20 sail drives. While primarily designed for Yanmar, this part is also a common service component for Komatsu and John Deere equipment that utilizes these specific Yanmar engine blocks.

As a critical engine component, this STD piston set ensures a precise fit within the cylinder bore, restoring compression, reducing oil consumption, and maximizing engine power output. It is a perfect solution for engine overhauls or rebuilds on small diesel engines in construction, agricultural, and marine sectors.

Key Features & Benefits

FAQ

Q: How do I confirm this piston is correct for my Yanmar 3TNV70 engine?
A: Please verify your engine’s model number and the existing piston size. This set is specifically for the Standard (STD) 70.00mm bore size. If your cylinder bore has been machined oversized, you will require an oversized piston. Always cross-reference your old part number (119515-22080) to confirm compatibility.

Q: Does this kit include piston rings and pins?
A: Yes, this is a Piston and Ring Set. It includes the aluminum piston and the complete set of piston rings (compression and oil rings). Please check your specific kit’s contents upon arrival, as wrist pins may be included or sold separately depending on the specific configuration.

Q: What is the installation procedure for this piston?
A: Installation should be performed by a qualified diesel mechanic. Key steps include: 1) Thoroughly cleaning the cylinder bore. 2) Installing the rings on the piston using a ring expander. 3) Lubricating the piston and rings with clean engine oil. 4) Using a piston ring compressor to install the piston into the cylinder bore, ensuring the arrow on the piston crown points towards the front of the engine. 5) Torquing the connecting rod bolts to the manufacturer’s specifications.
