    Poulan 25cc: Installing Piston/Rings in Cylinder?

    I have just a little more finishing work to do on my Poulan 25cc before it's time to reassemble it.

    What is the best way to reinstall the piston & rings (dual rings) into the cylinder without breaking them?

    Thanks in advance!
    John

    RE: Poulan 25cc: Installing Piston/Rings in Cylinder?

    did you leave the rings on the piston? or did you get new ones or something? I usually start on one end of the ring and work my way around, with a twin ring start with the lower one first.

    as far as getting the piston back in the cylinder, 90%+ of the jugs out there are tapered on the bottom, I've found they can just be pushed back in and push the ring with your fingernail or something easy and get it back in the hole... it's not as complicated as a lawnmower engine or car engine and needing a ring compressor...

    Thanks for your reply RFB- That's what I needed to know! I left the OE rings on the piston and needed to know how to put the piston back into the cylinder without busting the rings.

    Thanks,
    John
