OEM Cross-Reference
This piston ring set directly replaces the following original Mitsubishi part numbers:
ME999540 – Compression ring set (6D16/6D17)
ME999955 – Oil ring set (6D16/6D17)
These numbers correspond to genuine Mitsubishi heavy equipment parts and are interchangeable with aftermarket equivalents from major manufacturers. For cross-checking, always verify ring thickness and groove dimensions against your specific engine serial number.
Compatibility
This piston ring set is specifically designed for Mitsubishi 6D16 and 6D17 diesel engines. Based on common industry applications, these engines are typically found in:
Excavators: Commonly used for medium to large hydraulic excavators in construction and mining.
Forklifts: Heavy-duty forklifts in warehouses and ports.
Bulldozers: Track-type tractors for earthmoving operations.
Trucks: Medium-duty commercial trucks and dump trucks.
Loaders: Wheel loaders and skid-steer loaders.
Buses: Coach and transit buses requiring reliable diesel power.
Note: Fitment is inferred based on standard OEM applications. Please verify compatibility with your specific equipment model and engine serial number before purchase.

FAQ
Q1: How do I confirm that these piston rings fit my specific Mitsubishi 6D16 engine? A: Check your engine serial number and existing ring dimensions. Our rings match OEM specifications for standard 6D16 and 6D17 engines. For engines that have been rebored or modified, measure the cylinder bore diameter and ring groove width. If your engine uses oversized rings (e.g., 0.25mm, 0.50mm), this standard set may not fit. Contact us with your engine details for confirmation.
Q2: What is the recommended installation procedure for these piston rings? A: Proper installation is critical for performance. Clean cylinder bores thoroughly and lubricate rings with clean engine oil. Use a piston ring expander to avoid distortion. Ensure ring gaps are staggered at 120-degree intervals and verify end gap clearance using a feeler gauge. Torque connecting rod bolts to manufacturer specifications. We recommend professional installation by a certified diesel mechanic.
Q3: How should I store these piston rings if not used immediately? A: Store rings in their original packaging in a cool, dry environment away from direct sunlight and moisture. Avoid exposure to corrosive chemicals or extreme temperatures. If the plastic bag is opened, reseal it or transfer rings to a sealed container to prevent dust contamination. Proper storage ensures rings remain within tolerance for up to 24 months.
