875499 Piston Ring Kit | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta piston ring kit in the 0.75 mm oversize grade, weighing 0.07 kg and listed for 4 applications across MD and AQD series engines. It is the rebored partner to the standard-bore kit 875498 in this run. Order by the measured bore and the oversize marking on the piston, not by weight — grade is the only reliable guide within a graded set.

🔌 Function

Seals a 0.75 mm oversize piston to the rebored cylinder wall, controls oil on the bore and carries combustion heat out to the liner.

⚠️ Common Signs of Failure

• Blue smoke on the overrun and rising oil use
• Compression down across one or more cylinders
• Breather blowing heavily under load
• Rings seized in their grooves at strip-down
• Bore worn or glazed on an engine already rebored once

🛠️ Service Notes

• Measure the bore before ordering — this kit suits a bore taken out 0.75 mm and will not seal a standard one
• Match the kit to the oversize marking on the piston crown, and check the end gaps in the bore before assembly
