KIT SVC PISTON NV PLATED SAS 582023101

I removed the four bolts on the bottom of the chain saw as well as the carburetor . Then carefully remove the cylinder from the piston. Then remove the retaining ring that has a spot to get an awl under the ring and pry it out. Use a punch and drive the old pin from the piston then lift the piston off of the connecting rod.Be sure to clea ... Read more n off all the old gasket maker mine was black so it made it easy to scrape it all off, I use a plastic putty knife so not to damage the surface. Now put one of the retaining rings on the side of the piston that doesn\'t have the spot where you can pry from. Use plenty of oil and mount the new piston and pin then the retaining ring. Now use more oil and lube the new piston and put the new ring in the groove carefully so not to break the ring. Slide the new plastic sides in and oil them. Run a bead of black gasket maker and let set for 30 min. Oil the new cylinder walls and carefully slide the new cylinder down over the new piston making sure the new ring is hitting the pin in the Ring groove. Button everything up and let it set 24 hours then you\'ll be ready to start the saw up. I put mine together yesterday and this afternoon it started on the second pull of the rope. Good luck with yours!

Disassemble engine. Cleaned crank and rod plus all bearings. Lightly lubed. Installed ring on piston. Put piston on rod with new wrist pin an clips an slid assembly in to cylinder an bolted it back in the housing. Finished assembling. Tuned carburetor, works great.

Completely disassemble chainsaw to unbolt cylinder out of plastic housing. Cleaned main bearing because that\'s where the piece came from to seize cylinder. Bearing seemed to roll smooth so only changed cylinder and piston. Changing main bearings would be as simple as pulling them off by hand. Reassemble everything. I make it sound simple ... Read more but I\'ve worked on dirt bikes a lot. To me it wasn\'t hard but regular backyard mechanic should be able to figure it out. Two strokes are pretty simple. Did look a few things up on you tube for help but got it back together and cuts great. Sounds completely different so the broken piece must have been there from new. Only had 20 min when it seized but sitting in my garage as spare for 3 years so warranty expired. I would say try it yourself because you\'ve got nothing to loose!

Tiny snap rings on piston pin are tricky
Make sure piston ring is situated properly on positioning pin
With a little finesse you donÆt need a ring compressor
Then make sure you donÆt let anyone use it who doesnÆt know that straight gas ruins 2-stroke engines

Disassembled the saw- removed the cylinder/crank assembly- removed crank/piston - removed lock ring from piston- removed pin- reinstalled new piston/ring , pin and lock ring- reassembled

This is a complete engine removal and dissassembly

Followed eReplacementParts video on YouTube - very helpful.
1. Drained the fuel and oil from the saw
2. Disassembled the saw to gain access to and remove the engine
3. Pulled the piston from the cylinder (wrist pin retaining ring had come loose and wedged between the piston and cylinder
4. Installed new pisto ... Read more n assembly onto the crank and installed it in the new cylinder
5. Re-installed the engine in the saw and reassembled everything else. Did have to chase a few threaded holes in the cylinder assembly with a tap as they were quite tight otherwise.
6. Filled the saw with oil and gas and started it after about 3 pulls.
Saw runs like new and for about $50 I avoided spending $300 on a new saw. Great parts that fit perfectly and are high quality. Highly recommend trying this yourself if you have any mechanical experience - there\'s not much to 2-cycle engines. Hardest part was reattaching the throttle trigger mechanism.
