Cam & crank gears for I-5 motors

[Phil Payne]

> When rebuilding the 5000 turbo I-5 motor, what is the consensus on having to replace the cam
and crank gears? There doesn't seem to be much of any wear on mine, and since they're metal
and the belt is rubber, it doesn't seem like much wear would ever occur. Then again maybe it's
one of those have to replace items... Thanks for the tip.

I've never had to replace a cam gear.

I replace the crank gear about one time in four.  The key thing is the state of the Woodruff
key that engages in the crank - if it shows any sign of cracking at the sides, I replace the
pulley.  I find I usually have to drill out the Allen screws that hold the pulley into the
rear of the harmonic damper.
