1990 Ezgo 3pg assembly
I’m ready to start assembling 3pg. I have new crank bearings & seals, new piston & rings assembly. The crank was so tight on the bearings coming apart I’m dreading assembling the cases. Also the new piston has an arrow on the top & no instructions as to where it goes. I assume it points to the exhaust port. The new rings have an R etched but again no idea. I’ve built quite a few Diesel engines so I shouldn’t be stressing 😀 This motor is just tiny & very different than what I’ve experienced. I’ll be grateful for any advice y’all can give me

Re: 1990 Ezgo 3pg assembly
There is a side port in the piston. That port faces the intake.
The rings are beveled. The bevel goes up. (The R goes up) There are alignment pins in the ring grooves. Make sure the ends of the rings wrap around the pins. Post #25 has your manual showing this. https://buggiesgonewild.com/showthre...=105501&page=3 |
