.....yeah that's the ticket ... who makes a FINE-tooth 10mm gear wrench ?

I have been using a 1/4 ratchet on the rest. How many of these have you done? ... I would think it would be EZier on a lift. I am doing this on a concrete floor. A 3 ton jack-stand ... a floor jack and TWO bottle jacks ...

One bottle jack uNder the oil pan and the other tweaking the tensioner ...
