Hi, you must completely disassemble the tensioner by pulling the plunger out of the end of the housing and reinserting it from behind after the housing (#14) is installed into the motor. The tensioner is a ratcheting type tensioner and unless you reload it from the back it will be too tight.

The ring goes on the piston. Whay do you say the chain is too tight? Are you having trouble tightening down the plug in the back of the tensioner?

when i install the tensioner the timing chain gets too tight and i can't turn the motor. so when i losen the tensioner the motor turns. but the tensioner is out about half inch.

It's possible that you have the chain doubled over somewhere. Have you rotated the motor around two or three times by hand with the tensioner loose?

That is correct.
Here is a nice write up on the head gasket replacement that you might find helpful.
Remember #14 and 15 need to be installed and tightened before the rest of the tensioner goes together.
