Hello,
So I am re-building my lawnboy after the connector rod broke from the crank shaft. When re-installing the piston and rod to the shaft, How are the needle bearings installed. The old ones ended up all inside the engine. Not sure if I have them all so I may purchase new ones. Do I just grease up the shaft and stick them next to each other like mini pretzel sticks on peanut butter? When buying new ones, are they contained in some kind of sleeve? Hmmm., I'm kinda hungry now.

You can use grease, but the last ones I ordered come stuck together with a glue-like substance. You just put them in and the gas/oil mix melts the adhesive.

O, and another thing. When I took the cylinder apart to get to the piston, I noticed there was no gasket or anything between the two parts. Do I need anything when I screw it back together? Is it torqued to anything special? What about torquing the connecting rod around the crank shaft.

What you should get is a very light product for sealing machined surfaces. You can get this at a Lawnboy dealer or at an auto parts store. I cannot think of the spelling of the product, but it comes in a very small tube, is usually a dark red/purple product, and is about the consistency of fingernail polish. Has to be heat and gas resistance. It's almost like a varnish when it dries. Just thought of it:

Good Luck.

I think I just learned something new here.

The Lawnboys do not use and actual head gasket, only the liquid sealer for the mating surfaces?

Well, up until their last couple of models, they didn't actually have heads. They had a cylinder/head/half crankcase combination, and a mating bottom half of the crankcase, which the carburetor attached to.
