Yanmar YM2000 Fuel Pressure/ hard starting

Ouch! You did the right thing, pulling the pistons.

I wonder if it was cranked with water in the cylinders to bust up stuff like that.

My guess is, at some point in time it was. If you look back on page 11 you will see the pictures I posted last night.

ouch ! Does that engine have cylinder liners ?

It appears to, I will try honing first, if it’s not enough then it will have to come all the way out and apart and go get re-sleeved. I was really hoping to be able to do an “in frame” rebuild, but we will see.

If you can get them out. You should be able to install new sleeves

What’s the best method to getting them out? I’ve done several gas engines and my old Cummins, but none have had sleeves.

never taken any out myself, but I have read in the past where someone has removed them.
If I'm not mistaken, there is a tool that is used to remove them.
Perhaps hoye has such a tool

Yes YM2000 has sleeves/liners.

Hoye diagram.

Note in the diagram, the crankshaft slides out the back of the block so replacing main bearings isn't trivial.

A buddy of mine is a certified diesel tech up at the semi dealership here in town. I’ll be borrowing his hone anyway, I’m sure he can help remove the sleeves if we decide they need to be replaced.
