BubzSI, you aren't kidding! It's pretty tight in there.
I got the GearWrench set and ended up messing with it today. Got the belt on and off OK, but I had some trouble getting it back on correctly. Consequently, I ended up pushing fairly hard on the tensioner when it was at its limits. I don't think I did any damage to the hydraulic mechanism (these things have to be built to take some pressure, right?) but the bolt ended up looking like this:
Is the shearing normal or did I push too hard? The socket with the GearWrench set is about the same depth as a box end wrench so it seems like the contact area would be about the same with a 0 offset long handled wrench...
Everything seems to work OK but I'm a little worried about continued use of this tool now...
