- Properly lubricate the pistons, rings, and cylinder walls with engine assembly lube before insertion.

Troubleshooting & FAQ
How do I know if these piston rings fit my engine?
These rings are for specific Volvo Penta AQ series 4-stroke gasoline engines (AQ 120B, 125A, 140A). Always cross-reference your engine's OEM part number with 275342. Checking the physical dimensions of your old rings can also help confirm fitment.
What are signs that my piston rings need replacement?
Common symptoms of worn or failed piston rings include excessive oil consumption, blue or grey exhaust smoke, loss of engine power/compression, and increased crankcase pressure (blow-by).
Is a special tool required for installation?
Yes, professional installation requires specialized tools such as a piston ring expander and a piston ring compressor to ensure rings are not damaged during installation and seat correctly in the cylinder.
Do these rings require a break-in period?
Yes, after a rebuild with new piston rings, a proper engine break-in procedure is crucial. This typically involves running the engine at varied loads and RPMs to allow the rings to seat properly against the cylinder walls for optimal sealing. Refer to your engine's service manual for specific break-in guidelines.
Is this a genuine Volvo Penta part?
This is an aftermarket replacement part, not an OEM component. It has been engineered to meet or exceed original specifications using comparable materials and is manufactured in an ISO 9002 certified facility with batch inspections for quality assurance.
