Re: Yamaha 50hp Piston Installation
Usually the pistons are installed from the head side while attached to the connecting rod, and then bolted to the crank via the rod cap. It is unusual to install the pistons on the crank side. Again why?<br /><br />Regardless, you can use your fingers, or two small flat tipped screw drivers (brass tipped if possilbe). A ring compressor won't work becasue of the block design and because the crank is probably in the way.
