OK I know a pic is worth a thousand words, so I'll
try to make this a little shorter than that.
You have a wheel that tensions the belt, a long arm,
a short arm, a spring and a 10mm stud/bolt.
the long arm has a little tang that goes into the wheel,
you also need a bolt to go thru the wheel to hold it in
place, the long arm goes behind the tensioner wheel,
and sticks out to the right as you face the engine.
The short arm hooks into the long arm, and the spring
hooks to the end of it and to the block, the slot in the
short arm is for the bolt/stud to go thru to lock the tensioner.
The tensioner goes on first, line up the timing marks on the
crank pully and the cam sprocket, and slip on the belt, now
hook the spring up and put in the stud/bolt, do not over tighten !!
it's a little bolt just snug by hand, be gentle the threads are
aluminum.
now tighten the tensioner wheel bolt and you should be done
with this part.
Good Luck
