Disaster blaster fix

Only you can inspect it. I have seen considerable talk on forums and fb groups that report bad wrist pin bearings. (Chi-NA).
If you haven’t started tearing it down, power wash it first

I got er apart yesterday the bearing on the crank to the rod is bad there is play in that so is this crank junk now? And how about the case there is some scuffing in the area the crank sits the walls look like some metal had shaved off the wall not terrible but I think I can save the case by cleaning it up I’ll post a pic of it later

You can get the oem. Crank rebuilt. Which is a good piece. Or buy a new one

At least get any chunks off that have any possibility of coming lose

What kind of play does the rod have? Up and down(bad)
Some Side to side is normal
Push rod to one side and insert feeler gauge see what you have. That's if you don't have up down play.

Replacing the rod is something best left to a machinist/professional. Runout between the two sides is like .00025” or something like that

Definitely let a machine shop that is setup to do it correctly

It is pressed apart. And pressed together in a jig
