Piston Kit 530069298 Fits Poulan 25DA 25S XXV Chainsaw

Piston kit that fits the Poulan 25DA, 25S and XXV chainsaws; the kit has the piston, rings, wrist pin and circlips. Replaces part number 530069298. Measure the old piston before ordering. Look at the cylinder through the exhaust port before fitting a piston alone, since deep scoring or flaking plating means the cylinder needs replacing too. Find the cause of the old failure, pressure and vacuum test the crankcase, and use a new base gasket and a ring compressor.

• PISTON KIT - Piston, rings, wrist pin and circlips. Replaces 530069298.
• FITS POULAN 25DA, 25S AND XXV - Measure the old piston before ordering.
• CHECK THE CYLINDER, NOT JUST THE PISTON - Pull the muffler and look through the exhaust port. Light transfer marks hone out; deep scoring or flaking plating means the cylinder needs replacing too.
• FIND OUT WHY IT FAILED - A scored piston had a cause: a hardened crankshaft seal, a split intake boot, a lean carburetor setting or the wrong fuel mix. Pressure and vacuum test the crankcase before the new piston runs.
• ON ASSEMBLY - Use a ring compressor, fit the clips with their openings away from the slot, check ring end gap in the bore, and use a new base gasket.
