Crank won’t turn

Not necessarily it depends on the degree of separation between the Pistons.

 

nah, I'm seeing wrong.

I'm having a hard time seeing straight lines anywhere, which just means I'm not good at perspective this way.

Edit: Can we get a pan out of all 6?

Edit2: #3 close ups at least. Something just doesn't seem right.

 

That thing should roll over unless jammed. I see no sign of rust being the culprit.
Bearings.......eh, maybe. Never seen one "welded". Seen them spun to nothing left but I haven't seen everything....yet.

 

You guys just tell me what more pics/how/ of what and I will get them for you. Also if you want more taken off what tools I may need so that way I don’t have to grab/buy a ton of tools to bring home fro work that I don’t have to. By the way thanks for all the help!

 

When you try to crank it it is in neutral right? It wont crank in gear...

 

It's about as neutral as it can be. It's sitting on it's ass.

 

What do you mean as it can be? It’s either in gear or neutral

 

Engine's out.

 

Does #3 have room to swing there?

 

Myself, I would pull the cap off this piston. If it's the problem rotating one way or the other should turn fairly easy. Piston looks scored but could be imaging tricks..should just need 12pt socket and breaker bar.

 

There's def. a couple don't seem kosher.

 

@Nickj67, look at the connecting rod cap #2. There looks like something wedged between the connecting rod and main cap.

 

I've got a klx 300 in my shop now that wouldn't turn. It ended up having a rust ring on top of the piston from sitting with water in it for an extended period. I've seen the same thing with jet skis. I think pulling the heads is a good idea. If that's not possible maybe stick a borescope down a plug hole to see what's up.

 

I am starting to think this engine had a piston go bad and was running rough when it was turned off and seized up from sitting after that.

 

If you pull caps and push pistons around, put some tubing on threaded studs so you don't scratch the crank.

 

Well I think this Is OP's first time into an engine this far? Doing great so far.

 

There is a lot of info here now. What do you guys think I should do next more pics or pull more stuff off?

 

Well caps or heads. One or the other to find problem.

 

caps, if he pulls the heads and sees nothing he still has to go back to this. If he pulls caps and the crank moves, he knows it's the cylinders.
