rebuilding top end

[northshore]

im trying to put my topend back together, but the pistons wont go inside the jug, is there a special way to compress the rings, im trying to do it with my hands, but am having a hard time. thanks in advance!

Put a big zip tie on them, but feed the tie backwards so the it will come back off. Make sure the the ring is seated right on the little pin in the piston that hold it from turning

If the jugs a freshly honed, you may need to put a little chamfer on the bottom, otherwise they should pup in 1 at a time with your fingures, make sure it is the right ring (size wise) rare, but sometimes get packaged wrong.

what they said, or get a ring compressor.

put ur cylinders on top of the pistons, try to hold the rings and just like try to push the pistons upwards while ur holding the rings, it worked for me when i had a broken piston and had to change em'

press harder or hit it with a bigger hammer.

would it be a bad idea to put some premix oil on the rings and piston to help slide it in?

You are supposed to prelube your top end w/the same premix oil you will be running in the first place! I belive the instructions from your pistons even tell you that! Once you lube everything up, you should have no problem getting those pistons to slide into the cylinders w/just your hands.

No, this is the engine, it doesn't need a hammer. Hammers and engines don't go together.

Make sure the split in the ring is lined up with the pin in the piston. I just use my hands and haven't ever had a problem.

Like PUSH THE THROTTLE said, the piston should go into the cylinder pretty easy if you have the gap in rings lined up with the marks on the piston, otherwise they will not go into the cylinder and cause dammage if you try to force them.
