Installation Instructions
David from ENID, OK
Unit was defective when bought
I ended up having to also replace the crankshaft bearing well as the cylinder kit. The owner thought the knocking was too much oil which led to a scori g of the cylinder when it needed crank bearing replaced. Sorry Huskvarna the first one wouldn't weedeat this was the second.

Manufacturer Part Number 575227901
This genuine manufacturer sourced replacement part is specially made for use with a variety of handheld lawn and garden equipment. This part is installed on top of the piston/connecting rod.

Tools Required: Receptacle for draining fuel, Torx wrenches, spark plug wrench, 10mm wrench (or adjustable), long-nosed pliers, rubber mallet, standard screwdriver, old starter rope (or similar cord), adjustable pliers, 2-cycle engine oil, razor blade, ignition gapping gauge. • Remove the air cleaner • Drain the fuel • Remove the air cleaner case • Remove the carburetor • Remove the intake insulator • Remove the spark plug • Remove the engine cover • Remove the insulator gasket • Remove the starter assembly • Remove the fuel tank • Remove the air duct • Separate the engine • Bind the engine • Remove the clutch • Remove the flywheel • Remove the starter pulley • Unbind the engine • Remove the muffler • Separate the cylinder from the crankcase • Remove the piston ring • Install the piston ring
Husqvarna Trimmer Piston Ring
PartSelect Number PS16365561
Manufacturer Part Number 545154001
This metal ring in your engine, known as the piston ring, seals the gap between the piston and cylinder wall. It makes sure that the gases produced during combustion do not escape and that the engine maintains the pressure it needs to run. If the piston ring is damaged, oil can seep into the combustion chamber, causing your engine to exhibit rough idling and your machine emit blue smoke. To switch out a defective piston ring, detach the old ring from the piston with a screwdriver. When installing the new ring, you may need to compress it to make it fit properly. Please be aware that this genuine OEM replacement part is bought individually. It is recommended that you replace all the piston rings in your machine at once, as they tend to wear down at the same rate. Carefully review your user manual to determine how many rings your machine needs before placing your order.
