S16R Piston Ring 37517-10010 For Mitsubishi Diesel Engine Parts

Product Details

Product Overview

This high-quality piston ring set, identified by the OEM part number 37517-10010, is specifically engineered for the Mitsubishi S16R diesel engine. As a critical component within the power cylinder group, this piston ring ensures optimal compression, oil control, and heat transfer, directly influencing engine performance and longevity.

Manufactured to OEM size specifications, this piston ring is a direct replacement part designed to restore the sealing integrity of the combustion chamber. It is ideally suited for heavy-duty applications where the S16R engine is commonly deployed, including construction machinery, industrial power units, agricultural equipment, marine propulsion, and generator sets.

Please verify your engine model and existing part number to ensure correct fitment. This component is a standard replacement part and does not include pistons or other assembly components.

Key Features & Benefits

• OEM Specification Fitment: Manufactured to the exact dimensions of the original Mitsubishi part (37517-10010), ensuring a precise fit within the S16R engine without the need for modifications.
• Superior Compression Sealing: Engineered to maintain high cylinder pressure, maximizing power output and fuel efficiency while minimizing blow-by gases.
• Optimized Oil Control: Features a dedicated oil ring design that effectively scrapes excess lubricant from the cylinder wall, reducing oil consumption and preventing carbon buildup.
• Durable Material Construction: Built from high-strength, wear-resistant materials capable of withstanding the extreme temperatures and pressures found in a heavy-duty diesel combustion chamber.
• Enhanced Engine Longevity: By maintaining proper ring-to-cylinder wall contact, this part reduces friction and wear on both the piston and liner, extending the overall service life of the engine.
• Rigorous Quality Control: Each set undergoes factory inspection to guarantee dimensional accuracy and material integrity before shipment.

FAQ

Q1: How can I confirm this piston ring set is correct for my S16R engine?
A: Please verify the part number stamped on your old piston ring set. It should match 37517-10010. Additionally, confirm your engine model is a Mitsubishi S16R. If you have a different variant (e.g., S16R-PTA), the rings are typically the same, but checking your engine serial number is the best practice.

Q2: Does this set include all the necessary rings for one piston?
A: Yes, this is a complete set for a single piston. It typically includes two compression rings and one oil control ring. You will need to purchase the correct number of sets for the number of pistons in your engine (e.g., 6 sets for a 6-cylinder S16R).

Q3: What is the installation procedure for these piston rings?
A: Installation should be performed by a qualified diesel mechanic. Key steps include: 1) Cleaning the ring grooves and cylinder bore. 2) Using a ring expander to avoid twisting the rings. 3) Staggering the ring end gaps (typically 120 degrees apart) to minimize blow-by. 4) Compressing the rings with a proper ring compressor before installing the piston into the cylinder. Always consult your engine’s service manual for specific torque and gap specifications.
