Kelly 1,029 #1 Posted September 4, 2008 I found a new short block for a HH60 that I might pick up, but not sure about correct diam. for the crank, I'd like to put this on my 603, but unsure of the size I need? as I have no motor in it So if any one know's how long and diam. Please help. This one is 2 3/4x 3/4 with a 1/4 keyway, will it fit any WH without changing the crank? or finding a pulley to fit. :USA: Share this post Link to post Share on other sites
