Just a quick question about installing an RM non-adj. roller on my '02 LS1 block. Is there any trick to pulling off the OE crank gear from the crank snout and sliding the RM double sprocket snout on or is this as straight forward as it seems (using a puller)?

 

Its pretty straight forward as pulling off with a puller and pressing a new one on. I used a threaded rod in the crankshaft, placed a pipe that fit over the crankshaft and used a nut and washer to push the gear on. My hardest time was making sure the upper/cam gear and lower/crank gear were lined up. You'll need a straight edge and feeler gauge to make sure that they are lined up.
