Probably!?? The locating pins on the crank bearings.They are off.
Just one being off will bind the crank.

well i think you are right jerry but i checked those pins and all three of them are almost flat .you can say there no pins anymore so now what should i do is they replaceable or should i start look for new motor ?

thanks for your help

Take a bearing off and dry fit it over the pin.
The pins actually come out and can be replaced.
Probably not gonna be easy but it can be done.
They need to be in there.
So if you can't get them out, then get another block.

A torch is about the only way to remove them.
that is if you can get a pair of vice grips on the stud.
You try the bearing on the pin?
These things are a very hard steel and pretty hard to bend/mush or mishape?
