Frequently Asked Questions

Do I need all engine numbers for a piston?
Yes, the piston is matched by the engine's model, type and code numbers rather than by appearance. Have all three numbers from the engine to hand before ordering so the part is matched to the engine fitted to your Ariens machine.
When are oversize ring sets used?
Oversize rings are used when the cylinder has been rebored, while standard rings suit a standard cylinder size. The key check is whether your engine is still on its standard bore or has been machined to an oversize dimension.
How do I order gaskets with piston parts?
Choose the gaskets to suit the same engine as the piston parts you are ordering. Matching them from the engine's model, type and code numbers helps keep the rebuild aligned with the engine fitted to your Ariens machine.
