New Chain Far To Tight

You have turned the eccentric hub?

 

They can seize, how much movement are you getting? Now may be a good time to grease the hub and bearings.

 

The chains the right length link wise?

I could stand to be corrected but from memory, with the chain off you should be able to rotate the eccentric hub through a full 360deg. rotation (unless it's seized).

 

Just count the links on the old chain. Count the links on the new chain. Then you'll know if it's the right length or not.

 

i think you can cause damage with a chain that tight

 

Don't ride it. You could cause significant damage to your output shaft and/or bearing. 10mm play is far too tight.

 

Return the short chain and get the one with the correct number of links. Adding more links = more rivetting = more points of potential failure. Ideally you only want the one riveted link. Don’t try to make a wrong job right, do it right the first time.

 

Always look for the simple solution first! And boy am I simple!! Before anyone else chirps up!
