Idler Pulley Not Aligned

["TECH" <tech2@tznet.com>]

	I changed the water pump and timing belt Tuesday in my '86 5ks. when I put
everything on I noticed the idler pulley would not go on in alignment.....it
was tilted in on the intake side.   The belt comes forward, from this not in
alignment, & it will grind against the lower timing belt cover.
	I keep trying to put it on, over & over again, hoping it will go on
straight each time, but it won't....
	What's wrong, how to fix

Thanx in advance
