Stnick, 'just a couple of questions: Is your chain the more likely 5/16" or actually 5/8"? The "sprocket" you refer to is, I believe, the chain "gypsy" upon which the chain wraps while being pulled. If you have a manual Lofrans this gypsy
is on the starboard side and you have a drum on the port to wrap your line rode
for raising. With the manual windlass
you would be present on the bow to transfer the line to the gypsy
at the begining of the chain, or likely, the gypsy has a middle groove than can accomodate the line. Although my horizontal manual windlass
is a different brand, I am very pleased with using it on my two rodes that are likely similar to yours. In addition, your presence on the bow while using the manual windlass
will make it easy to assist in leading the rode
into the appropriate chain locker.
