48mm Cylinder Piston Kit 503541171 Fits Husqvarna 262XP

48mm cylinder and piston kit that fits the Husqvarna 262 and 262XP chainsaws, with installation instructions. The kit has the cylinder, piston, rings, wrist pin and clips. Replaces part number 503541171. Measure the old piston before ordering. Pressure and vacuum test the crankcase first, since a hardened crankshaft seal or a split impulse line will score the new piston the same way it scored the old one. Clean the mating faces to bare metal, use a ring compressor and tighten the cylinder bolts evenly.

• 48MM CYLINDER AND PISTON KIT - Cylinder, piston, rings, wrist pin and clips, with installation instructions. Replaces 503541171, also written 503 54 11-71.
• FITS HUSQVARNA 262 AND 262XP - The 48mm bore saws. Check the model plate and measure the old piston before ordering.
• WHEN THE CYLINDER GOES TOO - Scoring you can catch with a fingernail, or plating that has flaked or worn through, means a new piston alone will not hold compression.
• PRESSURE TEST FIRST - A hardened crankshaft seal, a split impulse line or a loose intake boot leans the mixture out and will score the new piston the same way it scored the old one.
• ON ASSEMBLY - Clean the mating faces to bare metal, use a ring compressor, fit the new base gasket, and tighten the cylinder bolts evenly in a cross pattern.
