Belt Conversion - Rear Cog Install

This blog post is the 2rd of 4 Belt Conversion posts. Here is the link to part one:

Rear Cog Removal

The Rohloff-Gates carrier only goes on one logical way, with the threads for the sprocket pointing out.  A liberal mount of waterproof grease applied to the threads of both the hub and the carrier, and the carrier screwed on easily.  I did find it convenient to leave the cog removal tool (from when I removed the original cog) in place.  This helped guide carrier and avoid cross-threading.

The cog's positioning wasn't quite so simple, as it  would screw on either way without being obvious as to which way was right.  It also isn't symmetrical, as one side has a lip, so there is a right way.  Wanting to install it correctly, I broke down and actually read the instructions that came from Gates.  Imagine that.  It didn't help at all.  The entire instruction sheet talked about proper belt handling.

So, I guessed. The cog only screwed on about two threads and stopped..  It didn't seem right ... that and the fact any time there's a 50-50 shot at anything, I guess wrong 83% of the time.  So, I guessed again.  Bingo, the cog screwed on farther and came flush with the edge of the carrier.  Lip side out ... again with plenty of water proof grease on all the threads.

Here's a pic ... note: the carrier is black and the sprocket silver.
