Idler pulley question, 86CGT

[Jeff Blanchard <jeffb@gamma1.lpl.arizona.edu>]

Hi,

I recently purchased an idler pulley to use in my timing belt replacement
on my 86 Coupt GT.  My first timing belt change attempt failed because I
could not manage to lock the crankshaft pulley (I tried the 12mm
hex-wrench trick without success).  So, I have not yet taken off the old
idler pulley, but I have a couple of questions:

1) The part that I purchased looks WAY too small.  It has an OD of 2"--the
one on my engine (10V-I5) looks about twice as big.  Beck/Arnley part#
024-1049, does anybody know how big it really is--it is one piece, right?

2) Is removal just a matter of pulling it off?

TIA,
