Since the Kriket is $10, and can be had at NAPA.... Why risk hand tensions? Sure the Kriket may not be wholy accurate... But prolly way more so than your hand.

The numbers don't seem correct - 4.0 Newtons of force equates to 0.899236 pounds-force.

According to this link, http://arnnworx.com/tensioning_belts.htm the proper tension for a new belt is 40 pounds (force) for the cam belt and 27-28 pounds for the balance shaft belt. IIRC the 9201 tool uses a value of 4.0 for a new cam belt and 2.8 for the balance shaft belt. This being the case, why all this frustration about units? It appears that the 9201 is calibrated in 10s of pounds (i.e. 4.0 = 40 pounds, 3.2 = 32 pounds, etc.) I've never used the 9201 (too expensive) so I don't know for sure though. Is this correct?

My car's PO didn't even use that method. He just put it on, started the engine, and the belt blew. My guess it was from belt(s) rubbing against each other and blowing up. I really wish I was there; there's nothing like being completely paranoid about starting the car up after I get it back together!
