Many thanx on the reply. It looked tight, but doable, but I will heed your words of wisdom. I have the CD which gives all the routings for variuos years and options. I'm not very good at reading and writing, but I can follow a pitcher (sic). Did not see anything about a pointer on the tensioner, this engine appears to have a "screen door spring" which has a lever to load and unload it. When you remove the bolt (holding the lever with a MB Pry Bar - Home Depot 3/8" black pipe) you can ease off the sprong, when assembling, pry it back into position and insert the bolt!
Righty tightie, lefty loosey!
