93 lt-1 engine going into my 83 Elko. I've got it all apart right now, and I noticed some slack in the timing chain. I might as well change it now, but is it really necessary to change the two gears as well? The crank shaft gear is the one that worries me, especially putting it back on, any suggestions?

A new chain always comes with two new gears. The old gears are as much of the wear/play as the chain.

normally youll need a puller to get the crank gear off, it may be stuck somewhat..


going back on, depending on the fit of the new gear on the crank,,
some times it will just tap back on with oil/grease and a big socket and little hammer..


you will need a balancer install tool for the balancer hub/flange,
to press it back on the crank, they are a tight fit.. do not hammer it back on..


make sure you get the right parts the LT1 had 2-3 different covers, WP/Opti drives over the years..
