Belt modifying an NEQ-6 pro astrophotographic mount - Part 4

This is part 4 in the belt modification project, which I have split into seven parts. This is the start of the modification phase. In this part I remove the old gear from the RA worm shaft and replace it with an aluminium gear for the belt. I also install the belt itself. After that, I replace the modified RA worm housing into the main upper housing and then replace that assembly back onto the lower assembly, which is on the tripod. Although bearings are not part of the Rowan Astronomy belt mod kit, I take the opportunity to replace the bearings on the worm shafts, replacing them with SKF 608-2RSH bearings. In astrophotography, replacing a chain of gears with a single belt in an equatorial mount addresses the problem of backlash. After this modification, the only mechanical transmission left is the worm gear, and this is adjustable for backlash. Backlash in your astrophotography mount prevents an autoguider (such as PHD2) from making fast adjustments, especially in declination. This is because reversing the direction your mount is moving involves a delay when the gears take up the backlash. The more backlash, the slower your autoguider is to compensate when the guide star drifts, and the worse your tracking is. The product I'm using is the Rowan Astronomy Belt Kit for EQ6 NEQ6 EQ6Pro NEQ6Pro and Orion Atlas EQ-G with Synscan goto drives.
