Removing piston

[logan]

I got a ridge reamer but will not fit in the cylinder. Am I doing something wrong?

What's the make and part number of your reamer? It should be adjustable but that doesn't mean the min size of the tool isn't too large for the B3's small bore.

^^ You probably have one for big bore engines. There should be an adjustment screw in the center. Turn it until you see which direction makes the side clamps move in and out. It should be counter clockwise to move them in. Wrap your hand around it and turn the screw until they compress together as far as they will go. If the tool still won't fit in the cylinder bore, you'll need a smaller ridge reamer. Does your cylinder actually have a ridge at the top? Those engines wear forever and unless you have a super high mileage or dirty engine, you may be able to just use a cylinder hone and clean it up.

I got them out. I'm replacing the pistons are the connecting rods pressed on to the pistons or how?

[Zanzer]

Yes, the wrist pins are pressed into the rod ends. It's probably best if you let a local machine shop do this for you if you don't have a press and experience with it. Shops typically don't charge much to press on the new ones and it's cheaper than damaging the rod and/or piston.
