timing belt age as a sole replacement indicator

[Cody Forbes]

Actually, Mike, I've done mine several times without the lock. I remove the bolt with an air impact gun, and for installation I have somebody in the car holding the brakes while in gear then torque the bolt to I believe 320lb/ft with a fair helping of loctite. Without an air gun I suspect you could loosen it with a breaker bar and somebody holding the brakes.

Rubber can take a "set" as well as harden over time, and if you start that up, the belt is quite likely to break or at least loose some teeth. Timing belts are cheap, engines are not - if in doubt, change the belt!

I've heard of people getting the crank bolt out without the tool, they lock the crank with the end of a pry bar (that's also a good way to get hurt when it slips), but you really can't get it back on tight enough without the tool. A couple of lengths of pipe are a great help, and you'll want a big torque wrench on reassembly.
