I want to replace rear Pulley and Belt on my 2002 HD Touring
It has a 1 1/2" belt and pulley I want to put on a 1 -1 1/8" pulley and belt
looking at a 2006 pulley pn# 40306-00 not sure if it will fit and if I need spacers.
Has anyone changed their pulley and belt and would share PN#'s?

 

Why would you want to change it ? The pulley you listed is for a Softail and has the wrong offset. You need the 2004-2006 touring parts. 40217-04 pulley with a casting number 40117-00, 5 pcs of 3737A bolt and the 40024-04 belt.

 

I have a 1990 Glide and have changed the whole rear end (wheel, brake and swingarm) for 2007 parts, with a 1 1/8" belt and 2004 stock touring pulley. The narrower belts are spaced away from the wheel, so you will be able to use a 150/80 tyre with plenty of clearance.
